CHAPTER 655

LAUNDRY AND DRY CLEANING

SECTION 1

FACILITIES

655-1.1 INTRODUCTION

Shipboard laundry and dry cleaning services are provided in support of the Navy’s overall mission. Whenmanaged and operated properly these services provide shipboard personnel with living and working conditionsthat contributes to a high state of crew morale, enhances general health and comfort, sustains maximum person-nel effectiveness and improves personnel retention. It is the responsibility of the ship’s supply officer to providelaundry and dry cleaning services for the crew. This responsibility is normally delegated to a junior Supply Corpsofficer and his subordinates. This section contains administrative and technical information pertaining to operat-ing policies and procedures, safety, shipboard design criteria, and general arrangement and outfitting require-ments.

655-1.2 POLICIES AND PROCEDURES

The general policies and procedures for shipboard self service laundry, institutional laundry and dry cleaningfacilities vary depending on the accommodation level and the type of facility installed.

655-1.2.1 Manning. Personnel are assigned to the laundry and dry cleaning facilities from the ship’s SHcomplement. The allowance of rated personnel is based on the assumption that supplemental TAD and nondes-ignated Seaman, particularly on larger ships, will be required to efficiently man and operate these facilities. Theorganization of a ship’s laundry and dry cleaning facilities vary with the size of the ship. On a smaller ship, suchas a CG or DDG, a Second Class Petty Officer may be assigned as the laundry supervisor with two Third ClassPetty Officers or Seaman assigned as laundry personnel. These three individuals are responsible for the entirelaundry operation. Larger ships on the other hand may have First Class Petty Officers assigned as shift supervi-sors and up to 30 SHs, Seaman and TAD personnel assigned to the laundry and dry cleaning facilities. Theassigned personnel may be designated to a specific laundry work station such as receiving, washing and drying,finishing, or issuing or be assigned to the dry cleaning operation. Individuals may be moved from time to timeto other stations based on workload and to provide training and experience.

655-1.2.2 Supervision. Laundry and dry cleaning responsibility generally come under the direct supervision ofa Ship’s Serviceman First or Second Class Petty Officer(s). The chain of command reporting to the ship’s sup-ply officer typically includes the division LCPO, disbursing or sales officer, and services officer on larger ships.The Ship’s Serviceman supervising the laundry and dry cleaning operation is responsible for maintaining sup-plies, ensuring the compartment is clean and the equipment is in proper working condition, training and assign-ing laundry personnel, and maintaining workflow and quality standards.

655-1.2.3 Scheduling. The laundry supervisor is responsible for administering the schedule approved by theship’s sales or disbursing officer. The schedule should include in-port and underway hours of operation and spe-cific times for receiving and issuing laundry. In order to maintain a balanced and efficient work flow the sched-ule should also include specific assigned day(s) when each division(s) may have their laundry processed. A laun-dry generally operates in 8 hour shifts. Depending on the size of the ship, the workload and available manpower,

655-1

Page 12: NAVAL SHIPS’ TECHNICAL MANUAL - · PDF filenaval ships’ technical manual chapter 655 laundry and dry cleaning this chapter supersedes chapter 655r1 dated 28 feb 1998 distribution

a laundry may operate up to three shifts a day. Due to a variety of factors, such as equipment down time andmanpower shortages, it is very common for ships to operate 24 hours per day and seven days per week whileunderway.

655-1.2.4 Security. The laundry and dry cleaning facilities are designated as Group IV spaces. The keys to thefacilities should be handled as outlined in NAVSUP P-487. The security of the laundry and dry cleaning facili-ties is the responsibility of all laundry personnel to protect against the loss of clothing and supplies, and damageto equipment due to misuse and unauthorized use. Unauthorized use of equipment by untrained personnel mayresult in injury, damage to equipment and possibly fires.

655-1.2.5 Safety. Safety is the uppermost important aspect of daily shipboard laundry and dry cleaning opera-tions. Prior to operating laundry and dry cleaning equipment the operator should observe the following generalsafety requirements:

a. Become familiar with the location and availability of emergency equipment (i.e. eyewash stations, fire extin-guishers, etc).

b. Become familiar with emergency egress routes.

c. Ensure the work area around equipment is dry and clear of obstructions.

d. Ensure work area is properly illuminated.

e. Become familiar with all equipment safety features described inSection 2and the equipment technical manu-als and adhere to all posted equipment operating and safety precautions.

f. Do not allow unauthorized personnel to operate equipment.

g. Ensure all safety guards are in place and all safety and interlocking devices are operating properly.

h. Keep hands, body and clothing away from moving parts at all times.

655-1.2.5.1 Navy Occupational Safety and Health (NAVOSH) Program Manual for Forces Afloat, OPNAVINST5100.19C, Vol II, Chapter C20 contains additional safety precautions for shipboard laundry and dry cleaningequipment and facilities. In addition, equipment technical manuals list specific safety precautions as well as safetyfeatures. The laundry supervisor is responsible for ensuring all laundry personnel are aware of and follow allestablished safe working procedures and precautions. Seeparagraph 655-3.8.2for specific safety and health con-siderations concerning perchloroethylene (dry cleaning solvent).

655-1.2.6 Industrial Hygiene. The mission of the ship’s laundry and dry cleaning facilities is to produce cleanclothing under sanitary conditions. The ship’s medical officer or senior Hospital Corpsman should inspect laun-dry and dry cleaning operation to ensure they comply with the sanitary requirements of NAVMED P-5010-2,Manual of Naval Preventive Medicine, Chapter 2, Sanitation of Living Spaces and Related Service Facilities.

655-1.2.7 Environmental Compliance. The Navy’s environmental compliance policies and procedures appli-cable to afloat units are outlined in Environmental and Natural Resource Program Manual, OPNAVINSTR5090.1B CH-2, Chapter 19. It is the responsibility of the commanding officer to ensure compliance with theguidelines, standards, and procedures of OPNAVINSTR 5090.1B.

655-1.2.8 Training. For supplemental training information not contain herein see Ship’s Serviceman 3 TrainingManual, NAVEDTRA 10176. Before operating equipment all personnel should complete the current PersonnelQualification Standards for Shipboard Laundry Equipment.

655-1.2.9 Heat Stress. The Navy’s heat stress program is outlined in Navy Occupational Safety and Health(NAVOSH) Program Manual for Forces Afloat, OPNAVINST 5100.19C CH-2, Volume 1, Chapter B2. It is theresponsibility of the commanding officer to establish and enforce an effective heat stress policy that ensures com-pliance with the requirements of OPNAVINST 5100.19C.

655-1.2.9.1 Definition. Heat stress is caused by any combination of air temperature, thermal radiation, humid-ity, air flow, and workload that may stress the body as it attempts to regulate body temperature. Adherence tomaximum heat exposure guidelines can prevent or reduce the adverse physiological effects of heat stress. Addi-tionally, sufficient recovery time in a cool environment will help reverse the harmful effects of heat stress. Heatstress becomes excessive when the body’s ability to adjust is exceeded, resulting in increased deep body tem-perature. This condition can cause fatigue, rash, cramps (particularly in the extremities and abdomen), profusesweating, dehydration, tingling in the extremities, pallor, rapid heartbeat, severe headache, nausea, vomiting, andpoor physical and mental performance in affected personnel. As body temperature continues to rise (due to pro-longed exposure), heat injuries (e.g., heat exhaustion or heat stroke) may occur resulting in severe impairment ofthe body’s temperature regulating ability and possible death. Recognizing personnel heat-stress symptoms andobtaining prompt medical attention for affected personnel is the responsibility of all hands.

655-1.2.9.2 Conditions and Causes. While heat stress conditions can occur in practically any space or area onboard a ship, laundries are one of the most likely places to have the conditions that may cause heat stress. Causesof heat stress conditions include operations in hot and humid climates, arduous physical tasks, steam and hotwater leaks, missing or deteriorated thermal insulation, ventilation system deficiencies and clogged lint filters. Inaddition, other factor that reduce physical stamina and enhance susceptibility to heat stress illness are dehydra-tion, lack of sleep, illness, use of medication, drugs and alcohol, and the presence of atmospheric contaminatessuch as combustion gases or fuel vapors.

655-1.2.9.3 Acclimation. In most individuals, appropriate repeated exposure to heat stress causes a series ofphysiologic adaptations called acclimatization, whereby the body becomes more efficient in coping with the heatstress. An acclimatized individual can tolerate a greater heat stress before a harmful level of heat strain occurs.Personnel acquire heat acclimatization only gradually, being fully achieved over a three or four week level ofsustained physical activity. Therefore, unassimilated individuals may increase their risk of incurring acute adversehealth effects from exposure to harmful levels of heat stress.

655-1.2.9.4 Monitoring. Dry-bulb thermometers shall be installed in the laundry and dry cleaning spaces IAWparagraph B0204b(1) of OPNAVINST 5100.19C. Temperatures shall be monitored and recorded IAW paragraphsB0204b(3) and (4) of OPNAVINST 5100.19C.

655-1.2.9.5 Recommendations. Personnel working in heat stress environments should adhere to the followingrecommendations:

a. Drink more water than satisfies the thirst. Do not wait until you are thirsty. It is important that personnel stayhydrated.

b. Eat three well balanced meals a day.

c. Get adequate rest. At least six hours of continuous sleep per 24 hours is recommended.

d. Wear clean clothing composed of at least 35 percent cotton (more natural fiber content allows more effectiveevaporation of water from clothing).

e. Do not take salt tablets.

f. Limit intake of caffeinated drinks.

g. Do not drink commercially prepared electrolyte supplements in place of water.

655-1.3 HABITABILITY DESIGN REQUIREMENTS

The basic habitability design criteria for shipboard laundry and dry cleaning facilities is set forth in Ship-board Habitability Program, OPNAVINST 9640.1A and reiterated herein.

655-1.3.1 Submarine Self Service Laundry. Submarines shall be provided with a self service laundry facilityon the basis of one 16-20 pound capacity washer and one 16-20 pound capacity dryer, per each 100 accommo-dations or fraction thereof and at least one hand iron and one ironing board.

655-1.3.2 Surface Ship Self Service Laundry. Surface ships with 100 or fewer accommodations shall be pro-vided with a self-service laundry facility to include at least one 16-20 pound capacity washer, one 16-20 poundcapacity dryer, 3 hand irons, and 3 ironing boards.

655-1.3.2.1 Surface ships with more than 100 accommodations may be provided with self service laundry facili-ties for processing civilian attire. If such facilities are installed, they shall be located in a dedicated space and ina separate location from the ship’s institutional laundry and in no way augment it’s required capacity. As a mini-mum, one washer and one dryer shall be provided per each 300 accommodations or fraction thereof (based on a22 hours per day, 7 days per week operating schedule). Whenever practical, the ratio of dryer capacity to washercapacity shall be 150 percent (i.e. 3 dryers for every 2 washers). Equipment shall be non-stackable, commercialgrade as approved by the Life Cycle Equipment Manager. Equipment and facilities shall incorporate all shipboardsupporting systems design criteria.

655-1.3.3 Surface Ship Institutional Laundry. Surface ships with more than 100 accommodations shall be pro-vided with a institutional laundry facility capable of processing a minimum of 24 pounds per week per accom-modation within a 96 hour work week based on the following requirements:

a. One change of work clothing, underwear, and socks per accommodation per day and one towel per accom-modation per day.

655-4

Page 15: NAVAL SHIPS’ TECHNICAL MANUAL - · PDF filenaval ships’ technical manual chapter 655 laundry and dry cleaning this chapter supersedes chapter 655r1 dated 28 feb 1998 distribution

655-1.3.3.2 Tenders and repair ships shall have institutional laundry capacities capable of supplementing facili-ties of two tended ships in addition to the requirements of their own ship’s company.

655-1.3.3.3 Irons, ironing boards and stowage shall be provided in all crew/troop berthing spaces.

655-1.3.4 Surface Ship Dry Cleaning. Surface ships with more than 100 accommodations shall have, as aminimum, dry cleaning press capability sufficient to finish press one dress uniform per accommodation permonth. Surface ships with more than 4,000 accommodations shall be provided with a dry cleaning facilitycapable of processing 3 pounds per accommodation per month within a 96 hour work week. The dry cleaningfacility shall be installed in a dedicated compartment separate from the institutional laundry, however when prac-tical, it should be adjacent to the manned laundry facility so that a common receiving and issuing access area isprovided. Dry cleaning finishing equipment shall be in the same compartment as the dry cleaning machine. How-ever, dry cleaning finishing equipment may also be installed in the same compartment as the laundry finishingequipment so that the dry cleaning press(es) may supplement the laundry presses to finish press laundered Cer-tified Navy Twill (CNT) garments. CNT may be easily damaged on a hot head laundry press if improperlypressed. On ships without a dedicated dry cleaning facility, one general utility dry cleaning press and vacuumunit, or one modified hot head laundry press on ships with all electric laundries, shall be installed in the laundrycompartment to press CNTs and wool. The modified electric hot head press shall have a grid plate installed onthe head and the head and buck thermostats shall be reduced to prevent shining or melting of the fabric.

655-1.3.4.1 All ships with a dry cleaning plant shall have a adequately vented stowage tank for dry cleaningfluid.

655-1.3.4.2 Deck drains shall not be located inside coaming areas of the dry cleaning plant.

655-1.3.4.3 Exhaust ventilation in dry cleaning plants shall incorporate all ventilation design criteria in accor-dance with NAVSEA 0938-LP-018-0010.

655-1.3.5 Unauthorized Installations. Any configuration change or alteration to a ship is prohibited as definedin OPNAVINST 4720.93 without approval from the Chief of Naval Operations (CNO) or the Naval Sea SystemsCommand (NAVSEA). Alterations to manned laundry or dry cleaning spaces or requests to redesignate the usageof existing spaces to self-service laundries must be accomplished using an approved K or D Ship Alteration(SHIPALT), Alteration Equivalent to a Repair (AER), or Ship Alteration Repair Package (SARP). Approvedalterations ensure proper configuration control, correct installation, proper logistic support, changes to documen-tation are made, all possible affected ships are identified, and that appropriate funding is set aside to accomplishthe alteration. The installation of stackable washer/dryers in manned laundry spaces or approved self-servicelaundries is prohibited as is the installation of commercial laundry equipment in unauthorized compartments suchas sanitary spaces, wardrooms, pantries, FLAG/C.O. quarters, etc.

655-1.4 LAUNDRY AND DRY CLEANING PROCESS

Self-service laundry, institutional laundry and dry cleaning processes vary depending on the accommodationlevel and type of facility installed.

655-1.4.1 Self Service Laundry. On submarines and surface ships with 100 or fewer accommodations eachindividual is generally responsible for washing their own uniforms, linens and civilian attire in the self-servicelaundry. Submarines may designate a single individual or″Laundry Queen″ who is responsible for the crew’s

655-5

Page 16: NAVAL SHIPS’ TECHNICAL MANUAL - · PDF filenaval ships’ technical manual chapter 655 laundry and dry cleaning this chapter supersedes chapter 655r1 dated 28 feb 1998 distribution

laundering. Shirts and dungarees are usually done separately from the whites which may result in at least twoloads per individual per week. Finishing is done by each individual on ironing boards located within the laundryor living spaces.

655-1.4.1.1 On surface ships with more than 100 accommodations each individual may wash his/her own civil-ian attire in the self-service laundry, should one be provided. If properly outfitted with equipment in accordancewith paragraph 655-1.3.2.1, the self-service laundry facility should be capable of processing a minimum of oneload per accommodation per week. The self-service laundry is for civilian clothes only and is not intended toaugment or reduce the workload of the institutional laundry. In order to maintain the integrity and reliability ofthe self-service laundry specific administrative controls must be invoked and adhered to. These are generally leftto the discretion of the ship and may include:

a. Establishing an operating schedule (i.e. hours and a weekly rotating schedule by division).

b. On large ships assigning a rotating watch to allocate machines usage, monitor the number, size and types ofloads (i.e. no uniforms, blankets, oily rags) and submit trouble calls.

c. Assigning responsibility for daily cleaning of the equipment and compartment.

d. Assigning responsibility for maintenance and repair of the equipment.

655-1.4.2 Institutional Laundry. The institutional laundry on ships with more than 100 accommodations hasfour basic areas; receiving, wash/dry, finishing, and issuing areas. The issuing and receiving areas on larger shipsshould be segregated, however, on smaller ships they may be adjacent to each other. The institutional laundryshould be arranged in an efficient manner utilizing an assembly line process in order to maximize production.Due to different handling practices and uniform materials, the laundering process for crew and troops (E-6 andbelow) is slightly different from that of Chief Petty Officer (CPO’s) and Officer. Articles to be laundered aredelivered to the institutional laundry either in bulk lots or in individual bundles. The receiving SH is responsiblefor inspecting, logging, marking and classifying all lots and bundles delivered to the laundry. Classification is theprocess of separating laundry according to color, fabric type, and degree of soil according to the wash formulasto be used (seeparagraph 655-1.4.2.4.1).

655-1.4.2.1 Receiving Bulk Lots. Bulk lots include combined divisional laundry (the crew’s personal clothing,towels and bed linen), flatwork (table cloths and stateroom bed linens) and organizational gear (medical/dentallaundry, cook’s aprons and barber’s smocks). Crew and troop dirty clothing is stowed in common soiled clotheslockers within the berthing compartments. This clothing is bagged in separate bulk laundry bags for whites andblues and is transported to the laundry by the designated compartment cleaner. Upon receipt the SH shouldinspect the bags to ensure the divisional name is stenciled on each bag in large letters, weight the bag and ensureit does not exceed the rated capacity of the washer-extractors, and ensure whites, blues and/or blankets are notmixed. Following inspection the SH should classify, mark and carefully log in the laundry. The bulk log shouldinclude the following:

a. Div/Dept - Identifies ownership of laundry.

b. No. of Bags - Indicates number of bags turned in.

c. White, Dungarees, Other (WT) - Indicates the total weight of each item by category.

d. Signature Blocks - Acknowledges delivery/receipt and issue/pick-up of laundry.

e. Dates - Indicates dates of receipt and issue.

f. Remarks/Comments - Any other pertinent information.

655-1.4.2.2 Receiving Individual Bundles. Individual bundles of officer and CPO personal laundry, assembledin mesh bags, are transported to the laundry by Food Service Attendants (FSA). Small non-sorted items, such assocks and underwear, should be contained in individual mesh bags. Bundles are combined and classified intosingle lots. The number of bundles assembled into one lot is determined by the classification of the items in thebundles. An individual lot should not consist of more than 50 bundles. Upon receipt of individual bundles the SHshould verify a Ship’s Store Laundry List is included with each bundle, classify, assemble bundles into individuallots, mark and carefully log in the laundry. The press deck log should include the following:

a. Name - Identifies ownership of laundry.

b. Laundry Mark - Identifies individual owner using first letter of last name and last four digits of social secu-rity number.

c. No. of Shirts - Indicates total shirts received.

d. No. of Trousers - Indicates total trousers received.

e. Other - Identifies miscellaneous items received.

f. No. of Underwear - Identifies total pieces of underwear and T-shirts.

g. Signature Blocks - Acknowledges delivery/receipt and issue/pick-up of laundry.

h. Dates - Indicates dates of receipt and issue.

i. Remarks/Comments - Any other pertinent information.

655-1.4.2.3 Identification. One of the main problems in the laundry is the loss of clothing. Adherence to a goodsystem of identification will prevent the loss or misplacement of clothing during the workflow process. There maybe several personnel handling the clothing and proper identification is essential in preventing loss. There are twotypes of laundry identifications; laundry marks and laundry lists. The actual method of identification depends onwhether the articles are received in bulk lots or individual bundles, the types of articles and the method of laun-dering. The clothing delivered to the laundry should already be individually marked. Each person is responsiblefor ensuring his or her own clothing is properly stenciled using a white or black indelible marking pen or has anembroidered name tape. The Navy Uniform Regulations requires enlisted personnel (E6 and below) to mark theirmilitary uniforms (blue chambray shirts, dungarees trousers, working coveralls and blue utility jackets) withembroidered name tapes. Embroidered name tapes are to be made of the exact fabric as the garment to which itis applied. Enlisted personnel may obtain embroidered name tapes from the Uniform Support Center (USC) bymail, phone, fax or SALTS. Ordering forms are available at the local Navy Exchange. Proper stenciling orembroidering is mandatory and improves the identification of personal laundry to ensure proper distribution andwill reduce the number of laundry claims. The Navy Uniform Regulations Manual contains guidance and proce-dures for stenciling various articles and the prescribed location.

655-1.4.2.3.1 Laundry Marks. When a bulk lot is accepted in the laundry it must be properly identified fromstart to finish. Individual items in the bulk lot do not have to be identified but some means of identification isrequired for each bulk lot, or portion, so it can be identified during any phase of the laundering process. Identi-fication of bulk lots is accomplished first by ensuring the laundry bag is stenciled with the divisional name inlarge letters and remains with the bulk lot during the entire laundering process. The bag should be hung on or bythe washer-extractor or tumbler-dryer. Also, markers made of small pieces of duck fabric and stenciled with thedepartments or divisions should be placed with the bulk lot when delivered to the laundry. The same marker canbe used week to week. In the event an oversized lot must be split, put a marker with each portion of the lot. If

it is necessary to process different lots together, use a laundry net bag for the smaller lot and place a marker ineach lot. All markers must remain with the lot or portions of lots during the entire laundering process. The iden-tifying mark should be written on the shell of the washer-extractor with chalk or a dry-erase marker. On multi-pocket washer-extractors identify the load in each individual pocket.

655-1.4.2.3.2 Laundry Lists. Officers and CPOs are required to identify the items they send to the laundry onShip’s Store Laundry List, NAVSUP Form 233. At the top of the list the customer must fill in personal identifi-cation information. On the lower part of the list they check the types and numbers of articles to be laundered.The list along with the laundry is turned in to the receiving SH. The receiving SH must verify the informationon the list. The procedure for identifying items in individual bundles described herein has been used successfullyin shipboard operations. This procedure may be modified to suit individual needs. The steps in the procedure areas follows:

a. Work on only one individual bundle at a time. This will prevent mixing of items from several bundles.

b. Remove the laundry list from the bundle and determine from the individual’s name and social security num-ber what the laundry mark will be. This mark is made from the first letter of the individual’s last name andthe last four numbers of the individual’s social security number. This is the standard type of laundry mark usedthroughout the Navy.

c. Mark the Ship’s Store Laundry List with the individual’s mark. This list now denotes ownership of the laun-dry in the bundle.

d. Count every item in the bundle and verify with the customer’s count. Note any discrepancy on the list andnotify the customer through whoever delivered the laundry bundle.

e. Check each article for a correct legible mark. If there is no mark put only one mark in the proper place. Donot mark such items as bath towels, wet articles, or dark colored fabrics. Use pronged marking tags on theseitems. These tags are narrow pieces of cloth approximately one inch long with metal fasteners in the end. Enterthe correct identification mark on the tags.

f. Check the insides of all pockets for any articles such as pens, pencils, combs and so forth. If any items arefound in the pockets, a notation should be made on the laundry list and logbook so these items can be returnedto the owner.

g. Check all articles of clothing for tears, stains, missing buttons, and so forth. Any items found to be damagedshould be noted on the reverse side of the laundry list and also in the remarks column of the logbook.

655-1.4.2.4 Wash Cycle. After the laundry is received, logged in, classified and marked it is transferred to thewasher-extractors. The primary goal of the washing process is to remove all soil from the items being washed.This is accomplished through a series of baths in which the soil is loosened from the fabric, suspended in thewater and rinsed away. A sour is used in the last rinse step to neutralize the detergent alkalinity and to decom-pose any remaining traces in the clothing.

655-1.4.2.4.1 Standard Navy Wash Formula Classifications. Standard Navy Wash Formulas were developed tomaximize cleaning efficiency while minimizing processing time, water consumption and chemical usage. Theformulas are intended to operate in fully automatic mode in order to minimize operator interface. All laundereditems shall be processed in accordance with the instructions indicated on the garment’s care label using one ofthe following standard Navy wash formula classifications (seeTable 655-1-1):

I White and Khaki Cotton, Polyester, and Cotton/Polyester Blend Materials.

II Utility and Organizational Clothing.

III Woolens, Synthetic/Wool Blends and Special Hazard Uniforms.

655-1.4.2.4.2 In order to minimize potential losses and maximize production efficiency all washing should beaccomplished by lot. Do not mix lots and do not mix lots of different classifications in multi-pocket washerextractors. Open net mesh bags should be used for non-sorted officer and CPO items such as socks, underwearand handkerchiefs. These bags are useful for separating smaller non-sorted items from larger items. Bags shouldbe loosely packed to ensure sufficient penetration of water and detergent. For maximum washing efficiency donot exceed the rated capacity of the washer-extractor. This will provide for maximum mechanical and chemicalaction and prevents wrinkling. Specific washer-extractor operating steps are described inSection 2. After comple-tion of the wash cycle, cleaned clothes are removed and transferred directly to the tumbler-dryers or finish worktransferred to the pressing station.

655-1.4.2.5 Drying and Finishing. All drying and finishing should be accomplished by lot and the identifica-tion marker kept with each lot during the process. When possible items that require approximately the same dry-ing time should be processed together. Drying time will vary depending on many factors such as quality of steamservice, load weight and material, and moisture content. However, the average drying time for a capacity load ofcotton items is between 20 and 25 minutes. Heavier cotton items will take longer while lighter synthetic andblended fabrics will be shorter. Extended drying times are an indication of a possible maintenance problem andshould be checked by the appropriate personnel. Do not overload dryers. Overloading will increase drying time,promote wrinkling and accelerate equipment wear and tear. Specific tumbler-dryer operating steps are describedin Section 2.

655-1.4.2.5.1 Flatwork items, such as bed lines and table cloths, and garments made of synthetic and blendedfabrics, can be successfully finished in the tumbler-dryer without the need for pressing by loading the dryer toapproximately 75 percent of it’s rated capacity and setting the temperature between 140° and 160° F. Itemsshould be removed as soon as the dryer stops and folded or placed on hangers. However, using the ironer willreduce the drying work load and produce a better finish than rough drying. For best quality finishing and ease ofpressing,

items should be pressed as soon as possible (i.e. while still damp) after completion of the washing cycle.

655-1.4.2.5.2 Heavy items may require preconditioning and should be partially dried for 5 to 8 minutes prior topressing. However, over drying can make pressing more difficult and reduce the quality of the finished product.Immediately after preconditioning deliver the garments to the press station. Do not allow the garments to dry.Cover preconditioned garments with damp cloths or nets to preserve their moisture content. If the article is notdamp enough, spray it with the spray gun. Specific flatwork ironer and laundry press operating steps are describedin Section 2.

655-1.4.2.5.3 At the end of the work day all dryers should be unloaded. Check the heat content of any work thatwill remain in the laundry overnight. Spread out or fluff any items that are still hot.

655-1.4.2.6 Assembly and Issue. Individual bundles and bulk lots of completed laundry require differentassembly and handling processes. Generally, bulk lots can be placed directly into the laundry bag in which theywere delivered. Items in individual bundles require specialized handling, thorough inspection and accurate count-ing.

655-1.4.2.6.1 Assembling Bulk Lots. Bulk lots are normally tumble dried and placed back in the divisionallaundry bag. Finished flatwork received in bulk lots, such as table cloths and sheets, should be folded, stacked,tied together and returned in the laundry bag. The assembled bulk lot should be delivered to the issuing area.Issue laundry to authorized personnel only. The bag should be weighed and the post-processing weight recordedin the bulk lot laundry log. The issuing SH and person receiving the laundry must sign the bulk log book in theappropriate columns acknowledging the post-processing weight.

655-1.4.2.6.2 Assembling Individual Bundles. Before receiving individual lots in the assembly area place eachcustomer’s laundry list in an assembly bin in alphabetical order. Handle finished laundry with care and collect itpromptly. Do not allow unfolded clothes from the net bags to accumulate on worktables or in the bins. Place thenet bags as marked in the proper bin. After all of the articles in an individual bundle have been placed in theproper bin, remove each item from the net bag, fold them and return them to the bag while checking off eachitem on the laundry list. Pin the net bag and attach the separate sock bag with a small laundry pin. Return thebag to the bin with the name or laundry mark clearly visible to make issuing easier. Check the laundry list toensure all finish press work (shirts and trousers) is included. Cover the press work with a suit wrapper and stapleor tape the laundry list to the wrapper. Issue laundry to authorized personnel only. The issuing SH and personreceiving the laundry must sign the press deck log book in the appropriate columns acknowledging the piececount.

655-1.4.2.7 Quality Assurance. Quality assurance in the laundry begins in the receiving area and ends with thereturn of clean and finished laundry to the owner. Every individual expects the processing and return of laundrybe accomplished in a professional manner. No articles should be returned to the owner unless it represents thebest quality work and care. When finish work is received in the assembly area it should be checked for cleanli-ness, stains, marks or any other blemishes. A shirt for example should have a quality look; clean, smoothly ironedwith no wrinkles and the proper creases. Any discrepancies found should be corrected before the article isreturned to the owner.

655-1.4.2.7.1 Sendbacks and Claims. Sendbacks are articles in individual bundles or bulk lots that requirereprocessing. Place articles sent back for reprocessing in a net bag so they can be reworked immediately. Send-

backs should receive priority handling so that deliveries can be made on schedule Claims by crewmembers forlost or damaged clothing should be handled in accordance with NAVSUP P-487.

655-1.4.3 Dry Cleaning. The dry cleaning facility on ships with 4000 or more accommodations has five basicareas; receiving/issuing. dry cleaning, finishing, spotting (spot removal) and minor repair of uniforms.

655-1.4.3.1 Receipt. Normally officer and CPO uniforms can be received, handled and processed on an indi-vidual basis. Enlisted personnel uniforms however, may require handling as a bulk lot due to the higher volumeof items. If divisional loads are handled as a bulk lot verify each uniform piece is properly marked prior to receiptto ensure proper distribution. The Navy Uniform Regulations Manual contains guidance and procedures for sten-ciling various articles and the prescribed location.

655-1.4.3.2 Identification and Marking. Proper identification and marking of dry cleaning articles is essentialin preventing items from being lost or misplaced. A master dry cleaning list is used as a record of the dry clean-ing processed for an individual and is used to save time and work, and reduces the probability of misplacingitems. Each customer must fill out the list, remove and retain the bottom claim stub and attach the list to thebundle. Each piece of dry cleaning work is recorded in the dry cleaning work logbook by the receiving SH. Apre-marked tag set is furnished with the master dry cleaning list for identifying each individual item that is goingto be dry cleaned. The receiving SH should detach and pin or staple one tag to each article and leave the remain-ing tags attached to the master dry cleaning list. The count of the remaining tags confirms the number of articlesbelonging to one customer when the articles are assembled.

655-1.4.3.3 Grouping and Classification. Similar uniform items should be scheduled together because the drycleaning load must be of similar material. Material groups are generally broken down into three categories; 1)officer and CPO uniform items, 2) enlisted uniform items, and 3) miscellaneous items such as flags, foul weatherjackets, etc. In general virtually all fibers and fabrics can be safely dry cleaned provided they are resistant to drycleaning solvent. However, all uniforms should be processed in accordance with the guidance on the care label.The two most important things to consider when dry cleaning items are classified are color and lint quality ofmaterial. Table clothes, drapes, flags, and so forth should be classified according to color, material, and lint qual-ity. Foul weather jackets, face masks, winter helmets, and winter trousers may be cleaned together. Signal flagsof different colors may be cleaned together as the lint transfer among the flags is not detrimental to their use.Impregnated, rubberized, oiled articles, or articles manufactured wholly or in part from leather should not be drycleaned as the solvent will damage such fabrics and material.

655-1.4.3.4 Inspection. Each article should be checked for detachable uniform insignia and for items in thepockets. Removal of pens, markers, lipstick and other foreign objects will eliminate a source of damage to theload. Put any such items in an envelope and attach it to the customer’s dry cleaning list. Inspect each article forspots and, if found, send to the spotter for treatment prior to dry cleaning. Inspect buttons, buckles and zippers,and check for tears or any other marks. Note any discrepancies on the customer’s dry cleaning list.

655-1.4.3.5 Pre-spotting. All articles should be examined for spots before they are dry cleaned. Analyze allspots to determine what substance caused them and what method should be used to remove them. At times pre-treating a spot may not remove it entirely but usually it will come out completely during the cleaning process.Post-spotting may be required if a spot was missed. If post-spotting is necessary the article must go back throughthe dry cleaning cycle to remove the chemical used in spotting. Specific spotting and stain removal treatment isdescribed inSection 3.

655-1.4.3.6 Dry Cleaning Cycle. State of the art dry-to-dry, closed-loop dry cleaning machines are much saferand easier to operate than the machines used in the past. Dry cleaning, or washing in a non-aqueous fluid or sol-vent, is the most effective known process for cleaning the broadest spectrum of natural and man-made fabrics.Dry cleaning is essentially a three-step operation: First, solvent is used to dissolve and disperse the soils on thefabric. Second, the solvent and soils are removed from the fabric. And third, the soils are removed from the sol-vent, and the solvent is used again. There are many reasons for dry cleaning garments rather than washing themin water. Some fabrics can not be washed in water for fear of causing distortion due to shrinkage, while otherfabrics are colored with dyes that dissolve in water. All authorized Navy garments are labeled with the appropri-ate care label which typically identifies standard Navy wash formulas I, II or III or dry clean only. This informa-tion is helpful to prevent damage to clothes during processing. It is important that shipboard laundry and drycleaning operators examine and adhere to the care labels on garments before laundering, when undecided as tothe material type or handling procedures. The dry cleaning machine both cleans and dries the load. When the drycleaning cycle is complete the cloths are dry and ready to finish press.

655-1.4.3.7 Assembling and Issuing. Once articles are finish pressed they are to be assembled and prepared forissue. The dry cleaning lists are used to assemble articles into customer groups. The number on each master tagattached to the dry cleaning list corresponds to the number attached to the various articles in a customer’s bundle.The tags are to be placed in numerical order and all articles belonging to each master tag collected. All articlesshould be inspected for broken or missing buttons, broken zippers, etc. prior to issuing. Ensure all belts andbuckles are properly returned. After all items are assembled into a customer’s bundle, the dry cleaning list shallbe attached and the bundle placed in the issuing rack to await pick-up.

655-1.5 ARRANGEMENT AND OUTFITTING REQUIREMENTS

The arrangement principles and ancillary outfitting for laundry and dry cleaning equipment and facilities areas follows:

1. Work flow process shall start with receiving and end at issuing in as direct a path as possible; that is, no longtransits or circuitous routes between equipment and processes.

2. Washer-extractors and deep sinks shall be grouped together and surrounded by a coaming to contain spillswhich will direct the spillage to a deck drain(s). Space should also be allocated within the washer-extractorcoaming area for water heaters, accumulators, and pumps. If the water heater and washer-extractors are notgrouped together a separate coaming area with deck drains shall be provided.

3. A dedicated ship’s hot water system shall be designed to meet the NAVMED P-5010-2 wash water tempera-ture requirement and to meet the washer-extractor hot water demands. A dedicated water heater is necessaryto meet the daily production output from the washer-extractors and provide a high quality of wash. Thewasher-extractor’s supplemental booster heater is provided as a backup should the dedicated hot water sys-tem not be able to meet the hot water demands. However, the supplemental booster heater’s primary func-tion is to partially raise and maintain the bath temperature to the NAVMED P-5010-2 requirement and is notintended as a substitute for a dedicated water heater.

4. Load transfer routes between washer-extractors and tumbler-dryers shall be minimized by installing washer-extractors and tumbler-dryers facing each other across a common aisleway whenever practical.

5. Equipment having revolving drums on a horizontal axis shall be oriented such that the axis of rotation is foreand aft.

SECTION 2

EQUIPMENT

655-2.1 INTRODUCTION

This section contains descriptive technical information pertaining to requisition, selection, characteristics,installation, operation and maintenance of shipboard laundry and dry cleaning equipment.

WARNING

All laundry equipment is equipped with safety devices to protect personneland equipment. If any such device is removed, by-passed or disabled, it shallbe replaced or repaired prior to operating equipment. Equipment shall notbe operated without such devices properly installed.

655-2.2 REQUISITION OF EQUIPMENT

Shipboard laundry and dry cleaning equipment must be selected from the equipment listed within theShip-board Laundry and Dry Cleaning Equipment Catalog (S6152-B1-CAT-010) or must be approved by the LifeCycle Equipment Manager on a case by case basis.

655-2.2.1 Equipment Catalog. The equipment specified within theShipboard Laundry and Dry CleaningEquipment Catalog is designed to meet shipboard environmental effects, offer simplified operator to machineinterface, meet shipboard safety requirements, and create an efficient means to meet the ship’s laundry and drycleaning needs. The Navy’s current laundry and dry cleaning equipment design philosophy is to keep the equip-ment as simple as possible to minimize operator interface and maintenance requirements by selecting equipmentwhich provides the basic operational functions as opposed to equipment which can perform a variety of unnec-essary, specialized functions.

655-2.2.2 Commercial Item Descriptions. Commercial Item Descriptions define the current configuration, fea-tures and essential characteristics, of each category of equipment and are reiterated herein. The equipment’sessential characteristics reflect the Navy’s current philosophy of utilizing commercial marine equipment and dis-continuing the use of Military Specifications. Invoking Military Specifications in the procurement of laundryequipment is no longer required. However, all laundry and dry cleaning equipment procured for shipboard instal-lation must invoke the requirements of the applicable Commercial Item Description. Any equipment which doesnot meet these requirements may degrade the efficiency of the laundry and dry cleaning operations, reduceequipment reliability, compromise standardization efforts and create safety hazards. Any waiver to a specificessential characteristic must be approved by the Life Cycle Equipment Manager.

655-2.2.3 Federal Acquisition Regulations. Users of theShipboard Laundry and Dry Cleaning EquipmentCatalog are reminded that the U.S. Navy’s supply system and procurement processes must abide by regulationsestablished by the Federal Acquisition Regulations (FAR). The FAR requires that all stock system procurementsbe on a competitive basis. Occasionally, manufacturers may be successful in providing equipment which meetsthe basic essential characteristics identified by the equipment’s Commercial Item Description but does not appearin the Shipboard Laundry and Dry Cleaning Equipment Catalog . If a manufacturer’s product is not con-tained in the latest issue of theShipboard Laundry and Dry Cleaning Equipment Catalog it shall not be

Page 28: NAVAL SHIPS’ TECHNICAL MANUAL - · PDF filenaval ships’ technical manual chapter 655 laundry and dry cleaning this chapter supersedes chapter 655r1 dated 28 feb 1998 distribution

excluded from the procurement process solely for this reason if their equipment is demonstrated to meet theCommercial Item Description requirements and receives the approval of the Life Cycle Equipment Manager.

655-2.2.4 Sole Source. Equipment of different manufacturers which is classified as functionally interchange-able is unlikely to be physically interchangeable. A situation may arise when the equipment issued by the sup-ply system may differ from that requisitioned. If there are unusual circumstances, such that existing space con-figuration constraints would preclude installation of any equipment other than that presently in place withoutrequiring extensive modifications to the ship’s configuration and/or extensive service modifications, or the equip-ment within the same category [that is, laundry presses, washer-extractor 35 to 200 pounds, etc.] would not befrom the same manufacturer, causing an operational, maintenance, repair or logistics problem for the ship, theadvice code of the requisition should indicate″2B″ for no substitute acceptable. A justification statement for solesource procurement must also be entered in the remarks block. Minor changes to foundations and/or services arenot considered acceptable sole source justification and will be rejected.

655-2.2.5 Local Procurement. Unless the urgency of the situation dictates otherwise, local procurement oflaundry and dry cleaning equipment and spare parts is discouraged. When the central supply system is circum-vented, vital demand information is not recorded at the central procuring agency. Without that information thecentral procuring agency cannot effectively forecast budget requirements for future equipment procurements andspare parts stock. Local procurement must be authorized by the central procuring agency and shall only be usedin instances when the lead time of the central procurement process prohibits timely delivery of the equipment tosupport the installation schedule. Regardless, whatever is requested, it must be equivalent to the equipment in theShipboard Laundry and Dry Cleaning Equipment Catalog and meet the Commercial Item Descriptionrequirements. Any interim changes or additions to the equipment’s Commercial Item Description in place at thetime of this publication are retained at NSWCCD-SSES. Most of the equipment shown in theShipboard Laun-dry and Dry Cleaning Equipment Catalog have National Stock Numbers (NSN’s) and Allowance Parts Lists(APL’s) assigned and are managed by NAVICP, DGSC or DISC.

655-2.2.6 Modular Equipment. Sectionalized equipment is available which allows transportation of disas-sembled equipment through shipboard passageways, doors, and hatches. Sectionalized pieces can then beassembled in the space using normal tools without the need for welding, cutting, or other types of hot work. Thisphilosophy allows for the installation of equipment without the need for cutting costly access holes and paths totransport a fully assembled unit into the laundry or dry cleaning space. Sectionalized equipment also providesgreater scheduling flexibility as installations may be accomplished incrementally and during any pier side avail-ability.

655-2.3 EQUIPMENT SELECTION

Whenever possible, laundry and dry cleaning equipment shall be selected from a single manufacturer for eachequipment category in order to reduce a ship’s logistical support requirements and minimize operational andmaintenance training requirements. Examples of equipment categories are: 50 and 100 pound capacity tumbler-dryers, laundry/dry cleaning presses, 60 to 200 pound capacity washer-extractors, etc. Available manpowerrequirements for operation, maintenance, and repair are also considered in the laundry and dry cleaning equip-ment selection process. Specialized high-production, automated equipment, such as tunnel washers, multifunctionpresses, folding machines and cabinet presses, are not specified over lower-production equipment, which performthe necessary basic laundering functions. Specialized high-production equipment perform many unnecessaryfunctions and also increases training requirements for the operators and maintenance personnel, and increasesshipboard logistic support.

655-2.3.1 Laundry Equipment. The selection and mix of laundry equipment depends on a variety of factorsincluding equipment redundancy, handling procedures, production rates, accommodation levels and ratio ofofficer/CPO to E-6 and below. In order to maximize the efficiency of shipboard laundry operation each of thesefactors must be evaluated for each individual ship class when determining the optimum mix and capacity ofwasher-extractors and matching tumbler-dryers.

655-2.3.1.1 The Navy’s primary concern when determining the recommended distribution of washer-extractorand tumbler-dryer capacities is to account for equipment down time by providing equipment redundancy when-ever practical so as not to render the laundry facility largely, or fully inoperative. For example, two 60 to 75pound capacity washer-extractors in place of one 150 pound capacity washer-extractor or two 100 pound capac-ity washer-extractors in place of one 200 pound capacity washer-extractor are considered better choices whenaccounting for equipment redundancy. However, the philosophy of building in equipment redundancy comes atthe expense of reduced operational efficiency, increased procurement and installation costs, excess manning,additional space requirements, increased weight, and greater maintenance and spare parts support. Due to theincreased reliability of modern state-of-the-art shipboard laundry equipment, future installations should take in toaccount the additional life cycle costs of installing redundant equipment. The use of fewer high capacity 150-200pound multi-pocket machines should be considered in place of multiple 60-100 pound machines in order tomaximize capacity to square foot ratio and minimize some of the inherent disadvantages of redundant equipmentinstallations.

655-2.3.1.2 The laundry handling process is also taken into account when selecting the mix of washer-extractors.As previously described inparagraph 655-1.4.2.1, E-6 and below laundry is received in bulk divisional laundrybags, generally weighing between 40-60 pounds. A divisional bag is generally processed together as a single bulklot in a compatibly sized single pocket of a multi-pocket washer-extractor or, if necessary, equally split and dis-tributed among smaller capacity multi-pockets. Therefore, the selection of a multi-pocket machine(s) in the 50 -70 pound per pocket capacity range is ideally suited to efficiently process the E-6 and below laundry while eas-ily maintaining the accountability of bulk divisional loads. Machines with smaller multi-pocket capacities, suchas a 60 and 100 pound machine (i.e. three 20 or 33 pound pockets), normally require additional operator steps,unnecessary sorting of large bulk lots, and will slow the laundry process and increase wear and tear on the equip-ment. On the other hand, machines with pocket capacities larger than 70 pounds, such as a 2-pocket, 200 poundmachine, creates wasted capacity since a bulk lot is rarely over 60 pounds and different bulk lots can not be com-bined and mixed. Multi-pocket machines with a per pocket capacity in the 50 - 70 pound range may also be bestsuited for processing E-7 and above laundry on larger ships such as aircraft carriers and large amphibious shipsdue to the large volume of laundry. However, since the E-7 and above laundry is received in individual bundles,sorted and combined into like loads, the selection of an open pocket machine(s) up to 60 pounds capacity, dedi-cated to E-7 and above laundry, along with bed and mess linens, is better suited to efficiently process this laun-dry on smaller ships such as cruisers and destroyers. The use of open pocket machines for officer and CPO sortedlots eliminates the extra operator steps necessary with a multi-pocket machine.

655-2.3.1.3 The production rate of an institutional washer-extractor is one load per hour or 60 minutes per load.The production rates tale into account downtime, light loads, and loading and unloading times. The total institu-tional wash capacity is based on 24 pounds per accommodation per 96 hour work week or 1/4 pound per accom-modation. The required drying capacity is determined by the ship’s wash capacity. The production rate of a insti-tutional tumbler-dryer is 1.5 loads per hour or 40 minutes per load. Roughly 70-75 percent of the wash load goesto the tumbler-dryers. The remaining, consisting of flatwork and officer and CPO uniforms goes directly to thepresses. As a general rule, dryer capacity can be determined by calculating no less than 50 percent of the requiredwasher-extractor capacity. However, for optimum matching of wash and dry capacities and to ensure a continu-ous work flow a design goal of 75 percent is recommended. 50 pound capacity tumbler-dryers are typically

matched with 60 pound open pocket and 150 pound multi-pocket washer-extractors and 100 pound capacitytumbler-dryers matched with 200 pound multi-pocket washer-extractors.

655-2.3.1.4 When calculating washer-extractor and dryer capacities the final selection of equipment shall berounded to the next highest single capacity of equipment available (i.e. 60 pound open-pocket, 150 and 200pound multi-pocket washer-extractors and 50 and 100 pound tumbler-dryers). 16-20 pound capacity washers anddryers, installed for C.O., VIP and officers of equivalent rank, should not be used in calculating total wash anddry capacities. The minimum quantity and capacity of institutional washer-extractors and tumbler-dryers neededto meet the habitability laundry requirements of OPNAVINST 9640.1 based on the ship’s accommodation leveland a properly manned laundry operating 96 hours per week is provided intable 655-2-1. Table 655-2-1is forgeneral guidance only. Each ship class should be evaluated individually on the basis of specific manning levelsand other related factors when determining the optimum mix and capacity of washer-extractors and matchingtumbler-dryers.

655-2.3.1.5 The production rate for laundry finishing equipment is based upon the arrangement of laundrypresses to form operator work stations and upon the item (i.e. trousers, shirts or flatwork) being pressed. Thestandard laundry press work station consists of two utility presses and one pants topper press arranged in aU-shaped configuration to allow one operator to finish press multiple garments at one time. The production rateof a standard press station is approximately 20-22 pieces (shirts, skirts and/or trousers) per operator hour. Theproduction rate of a single utility press is approximately 10 pieces (shirts, skirts and/or trousers) per operatorhour. The minimum quantity and types of laundry presses needed to meet the habitability laundry requirementsof OPNAVINST 9640.1 based on the ship’s accommodation level is provided intable 655-2-2. Table 655-2-2isbased on a properly manned laundry operating 96 hours per week.

655-2.4 WASHER-EXTRACTORS

Washer-extractors perform the following principle functions: water and chemical injection, wash/clean, rinse,drain, and water extraction. Washer-extractors are comprised of two basic parts: an outer shell or tub and arevolving cylinder within that tub. The shell holds the water and chemicals and the revolving cylinder holds theclothing. The cylinder is highly perforated with small holes on it’s outer surface. These small holes allow the

655-21

Page 32: NAVAL SHIPS’ TECHNICAL MANUAL - · PDF filenaval ships’ technical manual chapter 655 laundry and dry cleaning this chapter supersedes chapter 655r1 dated 28 feb 1998 distribution

chemicals and water to enter, saturate and pass through the clothing while retaining the clothing within the cyl-inder. The clothing is cleaned by mechanical and chemical action. The mechanical action is dependent on thenumber and height of the rises and falls of the clothing per unit of time within the cylinder. Chemical action isdependent on the correct amount of chemical product per unit volume of water. Too much chemical product perunit volume of water causes chemical particle entrapment within the garment fibers which causes yellowing ofthe garment during drying or finishing. Too little chemical product per unit volume of water decreases chemicalcleaning action. Extraction is performed after the tub has been drained to remove large amounts of water fromthe clothing. The extraction process is created by the acceleration of the cylinder from the slow rotation of wash-ing to a much faster rotation. With the cylinder rotating at a high rate of speed, the centrifugal force removes amajority of the water from the clothing.

655-2.4.1 35 to 200 Pound Capacity; Institutional. Washer-extractors having a load capacity of 35 to 200pounds shall be manufactured in accordance with Commercial Item Description A-A-59469 having the follow-ing classifications:

655-2.5.4 Operational Procedure. General tumbler-dryer operating steps are provided herein:

NOTE

Different makes, models and types of tumbler-dryers have slight variations intheir principle operations. For precise operating steps refer to the Navy approvedor COTS technical manual.

CAUTION

Never leave the laundry space unattended while tumbler-dryers are inoperation.

WARNING

Fire hazard potentials exist during the drying process. The maximum dry-ing temperature setting should not exceed 185° F. Lint must be removed toprevent excessive temperatures due to a reduction of airflow though thetumbler-dryer. A 135° F cooldown cycle is required to remove residual heatfrom the load in order to prevent spontaneous combustion.

1. Check the primary and secondary lint traps or lint arrester for lint; clean if necessary. During normal opera-tions the primary and secondary lint filters shall be cleaned every 2 hours and 8 hours respectively, and atthe end of the work day.

2. Energize the ship’s exhaust ventilation system which is connected to the tumbler-dryer’s exhaust outlet.

3. To prevent thermal shock and premature failure of steam coils a pre-heat cycle is required. Open the steamcondensate line valves and verify steam inlet line valves are closed.

4. Set timer for 5 minutes.

S9086-V4-STM-010/CH-655R2

655-39

Page 50: NAVAL SHIPS’ TECHNICAL MANUAL - · PDF filenaval ships’ technical manual chapter 655 laundry and dry cleaning this chapter supersedes chapter 655r1 dated 28 feb 1998 distribution

5. Set thermostat at the maximum temperature of 185° F.

6. If tumbler-dryer is equipped with dampers, set them on hot.

7. Slightly crack open the steam inlet line.

8. Push the start button to energize the tumbler-dryer.

9. Slowly open the steam inlet line during the 5 minute pre-heat cycle. If too much steam is emitted to thetumbler-dryer at once, the copper piping in the steam coil will expand rapidly and any remaining condensatewill flash to steam and cause damaging steam piping hammer.

10. Cancel buzzer at the end of the pre-heat cycle.

11. Load the tumbler-dryer with clothing from the washer-extractor. The amount of clothing to be loaded into atumbler-dryer shall not exceed the weight capacity of the tumbler-dryer using clothing/garment dry weight.

12. Close the loading door.

13. Set timer for proper drying time (approximately 25 to 30 minutes). The proper drying time is dependent onthe type of clothing being dried and the load size.

14. Set the thermostat at the proper drying temperature which is dependent on the type of clothing being dried.The drying temperature should not be set above 185° F.

15. If the tumbler-dryer is equipped with dampers, set them on hot.

16. On tumbler-dryer without automatic timed/temperature controlled cooldown, set the cooldown timer for 10minutes.

17. Push the start button to energize the tumbler-dryer.

18. Routinely check the temperature gauge on the tumbler-dryer during the drying cycle to ensure drying tem-perature does not exceed 200° F. If drying temperatures exceed 200° F, the space supervisor should be noti-fied for immediate corrective action. A tumbler-dryer operating above 200° F is a serious fire hazard andshould not be operated.

19. At the completion of the drying cycle the cooldown process should bring the tumbler-dryer temperature to135° F or less. If the cooldown cycle does not cool down automatically or during a set 10 minute cooldowntime interval, notify the space supervisor for immediate action. A tumbler-dryer operating without cooldownmay produce conditions allowing for spontaneous combustion of garments after the drying process.

20. After the buzzer sounds at the end of the cooldown cycle, unload the tumbler-dryer. Promptly removetumbler-dryer loads and manually fluff to remove residual heat. Residual heat can produce spontaneous com-bustion under certain conditions.

21. At the end of the work day, secure steam inlet and condensate valves on steam heated tumbler-dryers.

655-2.5.4.1 Operational Check-out Procedure. In order to ensure safe and proper tumbler-dryer operation andprior to placing machine in service the following general operational check-out procedure is recommended:

NOTE

Different makes, models and types of tumbler-dryers have slight variations intheir principle operations. For precise operating steps refer to the Navy approvedor COTS technical manual.

S9086-V4-STM-010/CH-655R2

655-40

Page 51: NAVAL SHIPS’ TECHNICAL MANUAL - · PDF filenaval ships’ technical manual chapter 655 laundry and dry cleaning this chapter supersedes chapter 655r1 dated 28 feb 1998 distribution

1. Ensure that the door safety interlock de-energizes the cylinder motor when the cylinder door is opened.

2. Ensure that the appropriate indicator lights are lit during the operating cycle.

3. Ensure that all temperature gauges are properly calibrated and function properly.

4. Ensure that the cooldown operation de-energizes the heating element unit (electric or steam) and cools thecylinder automatically to approximately 135° F.

5. Ensure that the drying timer is operational and adjustable from 0 to not less than 60 minutes.

6. Ensure that the steam solenoid operates properly on steam heated tumbler-dryers.

7. Ensure that the buzzer sounds at the end of the drying cycle.

8. Verify correct thermostat operation.

9. Inspect the drum and fan support bearings for wear.

10. If the tumbler-dryer is supplied with air dampers, check that they properly work in deflecting airflow throughor around the heating coils.

11. Ensure that the fan/blower assembly is rotating in the proper direction.

12. Ensure that cylinder basket reversal is between one to four times per minute with proper dwell time betweenreversals (that is, cylinder basket stops rotating before the drive motor is re-energized in the opposite rota-tion). Tumbler-dryer should be fully loaded to verify the proper dwell time setting.

655-2.5.5 Maintenance Requirements. The supervising petty officer is responsible for ensuring the tumbler-dryers are properly cared for and maintained. Dirt, grease and other accumulations should be removed daily fromthe exterior of the machine. Operators should monitor mechanical problems that may occur between scheduledmaintenance checks. Typical problems may include, leaking valves and steam coils, broken and inoperableswitches, faulty thermostat or temperature gauge, misaligned cylinder basket, inoperable safety interlockingdevices, etc. Any equipment malfunction or emergent maintenance problem should be reported immediately tothe supervising petty officer. Only qualified shipboard maintenance personnel should perform mechanical or elec-trical maintenance. Laundry personnel shall not perform this type of maintenance.

655-2.5.5.1 Lint Traps and Heating Coils. Primary lint filters and the interior lint chamber should be clean afterno more than two loads. The secondary lint filter should be cleaned after every eight hours of operation. Dustand lint which accumulates on the heating coils must be removed daily. Improper maintenance of lint traps andheating coils will extend drying times by reducing the efficiency of heat transfer and restricting airflow.

655-2.5.5.2 Fire Hazards. The potential for shipboard dry fires has been reduced significantly through the useof permanent press controls and safety interlocking devices such as high limit thermostats and air flow switches.Operators must be familiar with the proper operation of these safety features. Any malfunction shall be immedi-ately reported to the supervising petty officer and the dryer shall be secured until the malfunction is corrected.Most shipboard dryer fires are as result of the following operator error or negligence:

1. Leaving dryers unattended.

2. Short cycling wash formula resulting in residual oils, greases and solvents remaining in clothing.

3. Over drying light synthetic items because they have been combined with heavier items.

4. Failing to use cool down cycle.

655-2.6 LAUNDRY FINISHING EQUIPMENT

655-2.6.1 Laundry Presses. A general utility and pant topper laundry press is composed of two steam or elec-trically heated pressing surfaces. The top pressing surface, the head, is the moving surface. The pressing surfaceof the head is a highly polished concave metal plate. The lower pressing surface, the buck, is a convex station-ary surface covered with a mesh/spring base pad, two layers of flannel and an outer cover cloth. The movementof the head to the buck pressing surface is accomplished through pneumatics and mechanical linkages. The shapeof the head and buck allows the operator to press a garment efficiently to a desired finish. Pressing of the gar-ment is done while the garment is damp (creases, folds, and wrinkles are relaxed). The laundry press applies highheat and pressure on the garment’s fibers to dry, straighten and set the finish. The padding on the press must bekept resilient to achieve quality finishing results while preventing damage to items like buttons and zippers onthe garments. A laundry press is designed to press cotton and cotton blend garments with high heat and pressure.Using ordinary pressing techniques to press polyester synthetics and wool garments on a laundry press will resultin permanent damage to the garment due to the application of high temperature heat. Polyester synthetics andwool garments can be pressed on a laundry press at reduced temperatures. However, the pressing of wool andpolyester synthetics should be accomplished on a dry cleaning press whenever possible since a laundry press willnot provide the desired quality and requires a special pressing technique.

655-2.6.2.2.1 Operational Check-out Procedure. In order to ensure safe and proper flatwork ironer operationand prior to placing flatwork ironer in service the following general operational check-out procedure is recom-mended:

NOTE

Different makes, models and types of flatwork ironers have slight variations intheir principle operations. For precise operating steps refer to the Navy approvedor COTS technical manual.

1. Ensure the feed rate adjustment of the flatwork ironer is smooth. Ensure smooth activation of the paddedcompression roller onto the heated cylinder.

2. Insure that the flatwork ironer finger safety guard is operating properly. The guard shall deactivate the ironerwhen engaged.

655-2.6.2.3 Maintenance Requirements. The supervising petty officer is responsible for ensuring flatworkironer is are properly cared for and maintained. Dirt, grease and other accumulations should be removed dailyfrom the exterior of the press. Operators should monitor mechanical problems that may occur between scheduledmaintenance checks. Any equipment malfunction or emergent maintenance problem should be reported immedi-ately to the supervising petty officer. Only qualified shipboard maintenance personnel should perform mechani-cal or electrical maintenance. Laundry personnel shall not perform this type of maintenance.

655-2.6.2.3.1 Waxing. Waxing produces a smooth finish on flatwork. Prolongs ribbon life, and prevents linenfrom sticking to the heated cylinder. Laundry personnel should wax the ironer every morning and after every 6to 8 hours of use. The ironer is waxed using a strip of cloth about 3 feet wide and the length of the cylinder.Wax, as recommended by the manufacturer, is to be sprinkled evenly over half of the strip and the other halffolded over. The cloth is then fed through the ironer, folded end first, several times. Care must be taken to notover wax the cylinder as this may cause the return ribbons and drive material to deteriorate. Wax shall never besprinkled directly on to the ironer.

655-2.6.2.3.2 Ribbons. Worn, discolored or torn ribbons shall be replaced by engineering personnel in accor-dance with the procedures described in the equipment technical manual. The ironer should be waxed followingribbon replacement.

655-2.6.2.3.3 Return Ribbon Friction Material. The return ribbon drive roll operates the ironer return ribbons.It is located in the front of the ironer under the canvas feed ribbons. For the ironer return ribbons to be drivenproperly, the ribbon drive roll must be properly covered with frictional material. Special 6 inch wide frictionmaterial wound around the drive roll is used for this purpose. When the friction material becomes smooth orworn, engineering personnel shall replace it in accordance with the procedures described in the equipment tech-nical manual. If this material is not replaced the ironer return ribbons will not be driven at he right speed. Returnribbons should run faster than the heated and padded compression rollers. Jamming or wrinkling of the linensunder the return ribbons indicate the ribbons are not running a the proper speed. This may be an indication thatthe friction material need to be replaced.

655-2.6.2.3.4 Pads and Covers. If the padding on the ironer pressure rolls loses it’s resiliency or becomesscorched or burned engineering personnel shall replace it in accordance with the procedures described in theequipment technical manual. If the padding at one end should become more compressed than at the other end

pass some heavy towels through the thicker end. This should compress the padding so it is similar in diameteracross the width of the roll. A minimum amount of pressure should be applied on the padding to extend the lifeof the padding. Maximizing the pressure on the padding will not improve drying but will cause the padding towear out faster.

655-2.7 DRY CLEANING MACHINES

The dry cleaning process is performed on garments which are damaged by, or do not clean well by washingin water with detergent and drying at high temperatures. The dry cleaning washing process uses charged syntheticperchloroethylene (dry cleaning solvent) to clean these fabrics. The dry cleaning machine performs three majorfunctions to accomplish the dry cleaning process: washing, extracting, and drying. The machine is automaticallyoperated by means of a electro-mechanical or microprocessor automatic formula control unit. The most conve-nient program is a single filtered bath with distillation. The dry cleanable garments are loaded into a perforated,cylindrical basket which will rotate inside a tub when in operation. Once the main door is secured, dry cleaningsolvent is pumped into the cylindrical basket passing through a set of filter units which exist in the machine toremove any impurities residing in the solvent. The garments are then cleaned by mechanical and chemical actionduring the wash cycle. When the solvent level for the wash process is reached, the base tank valve closes andsolvent is continually circulated through the filters and basket. After the wash process the dry cleaning machinedrains the solvent from the cylinder back into the base tank and enters the extract process. The extraction of drycleaning solvent from the garment is performed by the centrifugal force created by increased rotational speed ofthe basket. After the extraction process, the dry cleaning garments are tumbled dried with heat. Heat is createdby activation of a heat pump refrigeration system and supplemental steam coil sending heated air into in the cyl-inder. The heat vaporizes the dry cleaning solvent and the vapor is drawn-off to a recovery housing where it ispassed through a refrigerated coil and is condensed to a liquid. The liquid then passes through a water separatoron its way to the base tank. The dry cleaning garments are then removed from the cylinder for finishing work.During the process solvent is introduces into the still automatically via the program. The distilling process elimi-nates dyes and other impurities that carbon core filtering elements are unable to remove from the dry cleaningsolvent. The distilling process vaporizes the solvent by indirect steam heating leaving the impurities behind inthe still which must be periodically cleaned.

655-2.7.1 20 Pound Capacity; Closed Circuit. Dry cleaning machines shall be manufactured in accordance withCommercial Item Description A-A-59362. The dry cleaning machine shall comply with the applicable EPANational Emission Standard for Hazardous Air Pollutants and the OSHA permissible exposure limits for perchlo-roethylene as applicable to afloat units.

655-2.8 DRY CLEANING FINISHING EQUIPMENT

655-2.8.1 Utility Presses. A dry cleaning utility press is composed of two heated pressing surfaces. The toppressing surface, the head, is the moving surface. The pressing surface of the head is a metal grid plate concavein shape and perforated with small holes. The head is comprised of a pressure chamber for heating and a spraychamber for relaxing garment fibers. The head pressing surface is covered with a perforated grid plate. The lowerconvex pressing surface (the buck) is stationary and is covered with padding and a cover cloth. The buck pressplate is also perforated with holes like the head and also contains a pressure and spray chamber. The movementof the head to the buck pressing surface is accomplished using pneumatics and mechanical linkages. The shapeof the head and buck allows the operator to press a garment efficiently and achieve a desired finish. Dry clean-able garments are finished using low temperature heat, pressure, and steam injection. During the pressing opera-tion, steam is injected through the garment from the head and buck spray chambers using the head operatinghandle and foot pedal respectively. The injection of steam into the garment relaxes the fabric fibers so that thefibers flow into position under low temperature heat and pressure from the press. To set the finish, an air vacuumunit attached to the buck spray chamber is used to draw-off the steam condensate and to dry the garment. Thevacuum is activated using a foot pedal which opens a vacuum valve to the buck spray chamber. The padding onthe press must be kept in good condition (resilient) to achieve good finishing results and to prevent damage toitems like buttons and zippers on garments.

655-2.9.1.1 Post-Installation Check-out Procedure. In order to ensure safe and proper sewing machine opera-tion the following post installation check-out procedure is recommended prior to machine operation:

1. Ensure that the machine wiring has not been cut or abraded, and has sufficient slack to provide strain relief.

655-2.9.2 Operational Procedure. General sewing machine operating steps are provided herein:

NOTE

Different makes, models and types of sewing machines have slight variations intheir principle operations. For precise operating steps refer to the Navy approvedor COTS technical manual.

1. In order to operate the sewing machine it is necessary to correctly insert the needle, thread the machine prop-erly, and to wind and insert the bobbin properly. To insert the needle, raise the needle bar to its highest pointby turning the hand wheel, loosen the needle clamp screw and insert the needle with the flat side of the needletoward the rear of the machine, then tighten the needle clamp screw. The upper thread is taken up from on thethread stand and brought through the thread guides, around the tension dial, through the take-up lever, throughthe thread guides, and then inserted through the needle. The needle bar should be at its highest point whenthreading the needle. After threading the needle, a sufficient amount of thread should be drawn through to pre-vent it from slipping out when operating the machine. The second thread source is the bobbin. To wind thebobbin, place an empty bobbin on spindle. It is necessary to turn the stop motion screw counter clockwise todisconnect the sewing mechanism. Take the thread from the spool and guide it through the thread guide andthen around the bobbin. Move the bobbin winder spindle to the left and then press the foot or knee pedal tobegin winding. When bobbin is full, move spindle to its original position, reattach the sewing mechanism byturning the stop motion screw clockwise and remove bobbin. The bobbin is inserted into the bobbin case, withthe thread being drawn under the spring and then through the delivery eye of the bobbin case. The bobbincase is inserted into the machine by holding onto the latch and placing it into the spindle stud until it catchesand then releasing it. After inserting the bobbin in the machine the bobbin thread must be drawn up by hold-ing the upper thread lightly with the left hand and while turning the hand wheel slowly with the right until theneedle enters the needle hole to catch the bobbin thread and draw it up. Both threads should be drawn underthe presser foot to the back of the machine in preparation for sewing. Material is sewn by placing it under thepresser foot, lowering the presser foot by means of the presser bar lifter and then applying pressure to the kneeor foot pedal. It is not necessary to pull or push the material, just guide it in the desired direction. Material ismoved by the feed mechanism which is located under the throat plate. Stitch sizes are determined by adjust-ing the stitch regulator.

655-2.9.2.1 Operational Check-out Procedure. In order to ensure safe and proper sewing machine operation andprior to placing machine in service the following general operational check-out procedure is recommended:

NOTE

Different makes, models and types of sewing machines have slight variations intheir principle operations. For precise operating steps, the operator should reviewthe Navy approved or COTS technical manual.

SECTION 3

USE AND CARE

655-3.1 INTRODUCTION

This section contains information and instructions pertaining to uniform fabric types, general fabric care,common wash problems, stain removal, specialized cleaning instructions of impregnated clothing, and launder-ing agents and supplies.

655-3.2 FABRIC TYPES

The cleaning process the uniform or linen receives in the laundry or dry cleaning plant depends upon the typeof fiber from which it is woven. It is important that shipboard laundry operators are familiar with the varioustypes of fabrics or fibers most often encountered. The fabrics of which uniforms and linens are made are classi-fied into three general categories: natural, synthetic and blends.

655-3.2.1 Natural Fabrics. Natural fibers comprise three general groups or classifications: vegetable, animal,and mineral. Common vegetable fibers are cotton and flax (linen). Those of the animal grouping are wool, silkand leather. Common mineral fibers are made from glass and asbestos and are seldom encountered in the ship-board laundry. Asbestos material shall not be laundered.

655-3.2.2 Synthetic Fabrics. Synthetic materials are man made of various types of cellulosic fibers (rayon),vinyl fibers, polyamides (nylon), and polyester. Polyester fibers are made with elements derived from coal, air,water, and petroleum. Not all polyester is the same; there are many types, which vary in their original chemicalproperties. Trade names such as Dacron, Fortrel, and Kodel are types of polyester fabrics. Polyester fiber is nearlytwice as strong as cotton and is wrinkle resistant. When resin, heat or crease treated the polyester fabric containsa memory or tendency to return to its original shape. When the garment has been properly processed throughwashing and drying, the smoothness of the garment need not be reestablished by pressing, and the garment shouldreturn to it’s original contours when placed on hangers or properly folded.

655-3.2.3 Blended Fabrics. Garments also include many combinations of natural and/or synthetic fibers calledblends. These are variously described, for example, as 65/35 or 50/50, depending on the percentage of the fibersin the blend. Where the fiber is half cotton and half polyester, it is called a 50/50 blend.

655-3.3 TYPES OF SOIL

In general there are four types of soils; chemical-soluble, water-soluble, insoluble and special. Many can beremoved during the wash process. Those that can not must be identified as they require special treatment.

655-3.3.1 Chemical-Soluble Soils. Chemical-soluble soils dissolve in chemical solvents. They include oils,greases, certain waxes, fatty acids, and vegetable, mineral and animals oils. Since these types of soils are gener-ally not soluble in water they may require special spotting treatment of small localized stains and dry cleaningof heavily soiled items. Lightly soiled laundered items should be washed at higher water temperatures (150° -160°F).

655-3.3.2 Water-Soluble Soils. Water-soluble soils dissolve in water. They include substances such as sugar,starch, gums, salt, flavoring agents and soils. They also include a wide variety of substances generally found in

S9086-V4-STM-010/CH-655R2

655-69

Page 80: NAVAL SHIPS’ TECHNICAL MANUAL - · PDF filenaval ships’ technical manual chapter 655 laundry and dry cleaning this chapter supersedes chapter 655r1 dated 28 feb 1998 distribution

foods and beverages such as mustard, catsup, soups and soft drinks. Perspiration stains are also included in thiscategory. The normal laundering process will generally remove these types of soils.

655-3.3.3 Insoluble Soils. Insoluble soils do not dissolve in water or chemicals. They make up the bulk of thesoils removed from the laundry. They include dirt, sand, carbon, ashes, dust, lint, hair, cosmetics, and dandruffThese soils are usually less visible than oils, greases or food stains but are damaging to the fabrics because oftheir abrasiveness. Most insoluble soils are dispersed during the wash cycle but their complete removal may bedifficult.

Insoluble soils are sometimes redeposited on the garments during the laundry process which causes a gray-ing effect on the fabric.

655-3.3.4 Special Soils. Special soils are insoluble in water and laundry detergents. They include ink, paint,nail polish, and various types of adhesives. They may be partially or completely removed by the spotting pro-cess.

655-3.4 FABRIC CARE

The processes established for shipboard laundering is limited to the few fabrics and fabric blends encoun-tered on a ship. In most instances, of the vast majority of fabrics and blends available commercially, the Navyis concerned with the proper care of only a very few. These generally consist of 100 percent cotton or denim,cotton and polyester blends, 100 percent polyester (CNTs), and wool or polyester and wool blend dress uniforms.

655-3.4.1 Care Label. The Federal Care Labeling Act, which became effective 3 July 1972, requires thatmanufacturers specify laundry or dry cleaning instructions, or both, on the label of each garment. The NavyClothing and Textile Research Facility has determined the proper care of all authorized uniforms. All authorizedgarments are labeled with the appropriate care label which typically identifies standard Navy wash formulas I, IIor III or dry clean only. This information is helpful to prevent damage to clothes during processing. It is impor-tant that shipboard laundry operators examine and adhere to the care labels on garments before laundering, whenundecided as to the material type or handling procedures.

655-3.4.2 Common Wash Problems. It is impractical to prescribe hard-and-fast rules regarding damage sufferedby fabrics in the laundry. Good practice requires that all processing times and temperatures, as well as concen-trations of chemical supplies, be reduced to a point at which effective cleaning will be obtained with minimumharmful effect on the fabric. Excessive bath temperatures, extended wash, rinse and extract times, and excessivedrying and pressing time and temperature should be avoided because they induce fabric damage, promote lintingand reduce garment life. Many common washing problems involve poor soil and stain removal, residues of lintand detergents, wrinkling, pilling and fabric degradation. The suggestions provided inTable 655-3-1should befollowed for satisfactory cleaning results.Table 655-3-1may apply to the cleaning of laundry in the ship’s insti-tutional laundry, self-service laundry or both.

Before washing, run hot waterfor a few minutes to clear lines.Drain water heater occasionally

655-3.4.3 Standard Navy Wash Formulas. The standard Navy wash formulas were developed and tested spe-cifically for shipboard laundry processing and should minimize many common wash problems. These formulasprovide the highest quality wash suitable to the uniform fabrics with the shortest possible washing cycles andminimum potable water and chemical consumption. These formulas must be strictly adhered to and the washer-extractor shall be operated in automatic mode only. Automatic operation will efficiently process the shipboardlaundry and also minimize the excessive equipment wear and tear associated with improper manual operation.

655-3.4.3.1 In addition to separating laundry articles by color and fabric type in accordance with the standardNavy wash formulas, the articles should also be separated by degree of soiling. Lightly soiled clothing should bewashed separately from heavily soiled items. Separating heavily soiled items will reduce the chance of causingthe lightly soiled items from turning gray or dull.

655-3.4.4 Polyester. In order to successfully process linen or garments which contain polyester fibers, there aregeneral guidelines which should be followed.

655-3.4.4.1 Do not wash whites and colors together, since white polyester blend fabrics may have an affinity forloose dye in the wash cycle. When loose or fugitive dye is picked up by white polyester fibers, it is often diffi-cult to remove.

655-3.4.4.2 Do not overload washwheel. This is necessary to insure adequate mechanical action, which is espe-cially important when laundering polyesters. Also, overloading will promote excessive wrinkling.

655-3.3.4.3 Avoid excessive temperatures or sudden changes in temperature. Sudden changes in temperature(thermal shock) will promote wrinkling.

655-3.4.4.4 When polyester uniforms (CNTs) require pressing they shall be finished on a dry cleaning presswhenever possible. Hot head laundry presses will easily damage CNTs if improperly pressed at high tempera-tures. If CNTs are pressed on a hot head press, the head and buck temperatures must be reduced. Also, a throwaway cloth for misting the garment or a head grid plate must be used to prevent the polyester fibers from melt-ing which will cause a permanent shine on the garment. Additional care must be taken when using a hot headpress since stains may be set in instead of cleaned out by the steam action of a dry cleaning press.

655-3.4.5 Wool. Wool fibers are very susceptible to mechanical injury when wet and excessive shrinkage whendried at high temperatures. Therefore all wool garments, with the exception of blankets, shall be dry cleanedunless instructed otherwise by the care label. In order to provide the highest quality of dry cleaning the solvent

Page 84: NAVAL SHIPS’ TECHNICAL MANUAL - · PDF filenaval ships’ technical manual chapter 655 laundry and dry cleaning this chapter supersedes chapter 655r1 dated 28 feb 1998 distribution

must be maintained at the cleanest level possible through continuous filtering and distillation. The paper and car-bon core filters will remove suspended particles, dyes and odors from the solvent. The still will remove oils,grease and other organic material. Proper operation of the water separator is also important in order to preventgarment spotting and shrinkage caused by residual water in the solvent.

655-3.5 STAIN REMOVAL

A large majority of stains are removed in the normal laundering process. Many stains however, require spe-cial treatment such as presoaking or prespotting prior to laundering, or by steam, air and vacuum spotting. Agedand laundered stains may become set and difficult to fully remove therefore they should be treated as soon aspossible and prior to laundering. Because some stains are difficult to remove it may be necessary to treat a stainseveral times.

WARNING

Use of the applicable personnel protective equipment, such as gloves,goggles, etc., and compliance with the precautions identified on the MaterialSafety Data Sheet of the particular stain removing chemical shall be strictlyadhered to. Stain removal should take place under the best possible lightconditions and with adequate ventilation. Special care should be exercisedwhen using flammable solvents to insure the absence of flames or spark pro-ducing tools. The use of nonflammable dry cleaning fluid and other toxicspotting agents may require the use of a respirator.

655-3.5.1 Stain Treatment. Some general stain treatment guidelines are as follows:

1. Read the labels. Before treating any garment, read and strictly adhere to its care label. The same applies todetergents, stain removers and spotting agents. A stain can be permanently set or a fabric can be ruined byusing chemicals improperly.

2. Test. Always test a detergent or chemical on an inconspicuous area of the garment before applying it directlyto the stain to check for colorfastness. A swatch from the seam allowance is usually the best place.

3. Pretreat. To pretreat stains, use a commercial prespotter suitable to the stain or presoak using a detergent con-taining enzymes or non-chlorine bleaching agents prior to laundering.

4. Treat from inside. Treat a stain from the inside of the garment. One good method is to place the fabric facedown on a paper towel. As you treat, change the paper towel regularly to prevent the stain from transferringback onto the fabric.

5. Blot stain. Always blot a stain, never rub it. Rubbing a stain can set it in permanently, and can also perma-nently mark or damage the fabric.

6. Rinse. It may be necessary to rinse some stain removal chemicals before they are allow to dry. Launder treateditems to remove loosened stains and treatment chemicals.

7. Be patient. Don’t over soak, or hand or machine wash a stained fabric for too long. This can cause soil toredeposit on the garment and can fade colors. If necessary repeat the treatment process.

8. Air dry. Air dry a garment until certain that a stain has been removed. Dryer heat will set a stain making itvery difficult to remove.

655-3.5.2 Stain Removal. Different stains require different treatments and properly treating a stain can guaran-tee at least an improvement in the garment’s appearance. Many of the stains encountered can be safely and com-pletely removed by pretreatment prior to laundering using commercially available prespotters, presoaking prod-ucts and stain removers. Knowing the exact type of stain and following the recommended treatment will aid insuccessfully removing it.Table 655-3-2provides general suggestions for removing many common stains.

Scrap residue from fabric and pretreat with a prespotter or laundry detergent. Launder inhottest water safe for fabric. If stain persists, place stain face down on paper towels andapply nonflammable dry cleaning fluid to the back of fabric. Allow fabric to dry, then rinse.Launder again in hottest water safe for fabric.

InkCAUTION

Some inks may be set in by laundering. Pretreat the stain before laundering.Using denatured alcohol or non-flammable dry cleaning fluid, sponge the reverse side of thefabric face down on a paper towel. Rinse thoroughly. Or hold the stained area taunt over themouth of ajar. Drip the non-flammable dry cleaning fluid through the spot so the ink will dropinto the container. Rinse. Hairspray may also work as a pretreater. Once stain is sufficientlyremoved, launder as usual.

Mildew, scorch Presoak item in fabric-safe oxygen bleach and hot water before laundering. If stain persistssponge with hydrogen peroxide. Rinse thoroughly and launder again.

Perspiration Use a prespotter or rub the area with bar soap. Also, treat fresh stains with ammonia andolder stains with white vinegar. Launder in hottest water possible without damaging fabricusing a fabric-safe oxygen bleach.

Rust, brown or yellow dis-coloration

CAUTION

Rust removers are powerful stain removers, but great care must be taken not todamage fabrics. Follow directions carefully.

For spots use a rust remover safe for fabric. For discoloration of an entire load use a prepack-age iron and rust stain remover reclaim system directly in the wash wheel.

Shoe polish - liquidbleach.

Pretreat with a paste of granular detergent and water. Launder using a fabric-safe oxygenbleach.

Then place stain face down and treat with a prespotter or non-flammable dry cleaning fluid. Rinse thoroughly to remove solvent. Let stand until dry.Launder in hottest water possible without damaging fabric using a fabric-safe oxygenbleach.

655-3.5.2.1 Commercial manufacturer’s such as A.L. Wilson Chemical Co. or ECOLAB, provide safe andeffective laundry and dry cleaning stain removal chemicals and systems. Refer to the manufacturer’s recommen-dations for specific stain removal treatments.

655-3.5.3 Spotting. Any stain which resist the normal washing process or locally concentrated pretreatmentremoval efforts must be removed by spotting. Spotting is a specialized art and requires skill in identifying thenature of the stain and in using the proper agent to remove it without damaging or otherwise affecting the cloth,or leaving a ring around the spot from which the stain was removed. The spotter must be familiar with textilefibers, sizing materials, dyes used, stains or spots likely to be encountered, and proper agents or chemicals io beused and their probable action on the various fibers and dyes. The following precautions are to be understoodbefore a stain removal operation is undertaken.

1. Methods recommended for white goods are equally effective for colored goods, providing the reagents usedhave no effect on the color of the material.

2. Tests always should be made on some hidden portion of the garment, such as any extra seam allowance thatmay be present, before the spotting agent is applied to the cloth.

3. Chlorine-bleach or concentrated and warm solutions of alkalies never should be applied to any material con-taining silk, wool, mohair, or other animal fiber.

S9086-V4-STM-010/CH-655R2

655-77

Page 88: NAVAL SHIPS’ TECHNICAL MANUAL - · PDF filenaval ships’ technical manual chapter 655 laundry and dry cleaning this chapter supersedes chapter 655r1 dated 28 feb 1998 distribution

4. Traces of mineral acids (such as sulfuric and hydrochloric) or acid salts that hydrolyze to form either of these,should not be permitted to dry or be pressed into cotton, linen, or rayon fabrics.

5. Rayon articles and other synthetic fabrics should never be treated with organic solvents unless resistance totreatment is known by preliminary test on an unexposed portion of the garment.

6. Color strippers are used to remove dye from fabrics; high-potency liquid titanium stripper is recommended. Itwill safely remove fugitive dye stains from white and colored articles in laundry and dry cleaning.

7. All agents used for stain removal must be rinsed from the article thoroughly prior to drying or pressing toprevent attack on the material.

8. Excessive frictional action should be avoided. This is especially important when treating silk and rayon fab-rics. Where some friction becomes necessary, chafing often can be avoided by working on the reverse side ofthe garment.

655-3.5.3.1 Large ships shall make full use of the spotting board, if installed, for stain removal. On smaller shipswithout a spotting board removal of small stains may be accomplished with minimum friction by one of the fol-lowing procedures:

1. Stretch the stained area over a bowl of cold water and apply the appropriate spotting agent with a medicinedropper. Gently work the agent into the stain with a nylon bristle spotting brush. Rinse garment thoroughly.

2. Place the stained fabric over a pad of clean folded cloth, paper towels or white blotters, and apply the appro-priate spotting agent with a medicine dropper or with a clean pad or cloth saturated with the spotting agent.Gently work the agent into the stain with a nylon bristle spotting brush. Rinse garment thoroughly.

655-3.6 SPECIAL INSTRUCTIONS FOR LAUNDERING CHEMICAL PROTECTIVE CLOTHING

There are two types of chemical protective suits in use aboard ship. The Chemical Protective Overgarment(CPO) is being replaced by the Advanced Chemical Protective Garment (ACPG) but the CPO will be used untilthe stock is exhausted and shelf life or operational life is expended. See NSTM Chapter 470, Section 5 for adescription of the configuration, capabilities and limitations of these garments.

WARNING

Do NOT launder the Chemical Protective Overgarment (CPO)! This couldcompromise the chemical protective capabilities of the suit.

655-3.6.1 Chemical Protective Overgarment (CPO). The CPO consist of a pair of trousers and a pull oversmock that are worn over the duty uniform. The coat and trousers are packaged together under a single stocknumber. The smock has an attached hood and has hook and pile fasteners at the waist and wrists. The trousershave adjustable suspenders and hook and pile fasteners for waist adjustment and ankle closure. The CPO has amodacrylic nylon outer shell to repel unthickened liquid agents and a chemical protective inner liner containingactivated carbon for protection against chemical agent vapor. Once the factory seal on the original packaging hasbeen broken, the operational service life in an uncontaminated environment is 100 hours of wear within 30 con-secutive calendar days. Do not wash the CPO. Air dry it if it is wet from exposure to sea spray, rain or perspi-ration.

WARNING

Do NOT launder Advanced Chemical Protective Garments (ACPG) thathave been exposed to chemical agent. This is not a decontamination proce-dure!

655-3.6.2 Advanced Chemical Protective Garments (ACPG). The Advanced Chemical Protective Garment(ACPG) is worn over the duty uniform or underwear. The ACPG consists of two pieces, a coat and trousers,which are packaged separately and issued under different stock numbers. The coat is hip length with an integralhood and has a front slide fastener, that, when closed, is covered by a flap with hook and pile fasteners. The trou-sers have high waist, adjustable suspenders, and a front slide fastener with a snap at the top and hook and pilefasteners for waist adjustments and ankle closure. The ACPG has a nylon-cotton (NyCo) poplin outer shell thatis treated to repel water and oil and an inner liner containing activated carbon for protection against chemicalagent vapor. The ACPG has a shelf life of 5 years if unopened. The operational service life in an uncontaminatedenvironment is 45 wear days or 120 consecutive calendar days once the factory seal on the original packaginghas been broken. It can be washed up to six times within 45 wear days.

WARNING

The ACPG item shall be laundered no more than six times during the 45 daywear period. Additional launderings may cause degradation of the protectivecapability of the ACPG. Do NOT dry clean ACPG items.

WARNING

Chlorine bleach shall not be used to wash ACPG items. Chlorine compro-mises the chemical protective properties of the ACPG material.

NOTE

For best results, all slide fasteners and hook and pile closures on ACPG itemsshall be secure prior to laundering.

NOTE

Seawater can be used for Step 1. If powdered detergent/oxygen bleach is usedwith seawater, instead of solid chemicals, quantity must be increased to 20 oz per100 lb basis. Solid detergent requires no adjustment. Use fresh water in Steps 2,4, and 5.

Powdered detergent/oxygen bleach should be added to the wash wheel once thewater level has been reached. Powdered detergent amounts are based on a 100 lbbasis and must be adjusted according to the size of the washer extractor used.Solid detergent is added automatically.

655-3.6.2.1 ACPG Washing Procedures. Each ACPG item can be laundered up to 6 times during the 45 weardays of use in an uncontaminated environment. Navy Wash Formula III shall be used to clean uncontaminatedACPG items. Formula III is a low temperature wash using either solid detergent or powdered detergent/oxygenbleach. The procedures for washing with Formula III are provided in Ship’s Serviceman Laundry Handbook,NAVEDTRA 10176.

WARNING

ACPG items shall be tumble dried at low temperatures (100° - 120° F) orair dried. Excessive heat compromises the chemical protective properties ofthe ACPG material.

WARNING

Wet ACPG items shall not be placed in the storage bags. Air dry thoroughlyprior to stowage. Do not iron or air dry in direct sunlight.

655-3.6.2.2 ACPG Drying Procedures. Tumble dry ACPG items at low temperature (100° - 120°F) or air dry.On ships equipped with dryers without an adjustable thermostat (i.e. dryers with only a high - low setting) oper-ate the dryer without heat. This can be accomplished by securing the steam valve on steam heated dryers or dis-connecting the control power to the heating element contactor on electrically heated dryers. Ensure temperatureis between 100° - 120°F before loading ACPG items. The ACPG items shall be removed from the tumbler imme-diately after drying is complete and immediately separated, folded and placed back in it’s own storage bag. Dry-ing may also be accomplished by hanging the items on hooks or lines away from direct sunlight.

WARNING

It is essential that each garment is placed back in it’s own storage bag afterbeing laundered. The ACPG Wear Time and Inspection Record form foreach garment stays with it’s storage bag while the item is being laundered.A laundry mark shall be assigned to each garment and recorded on thisform and in indelible ink on each garment label to ensure that each garmentis returned to it’s own storage bag with the correct Wear Time and Inspec-tion Record. A blunt marker shall be used to mark the garment label toavoid puncturing the garment.

655-3.6.2.3 ACPG Wear Time and Inspection Record. When an ACPG item is unpacked from the original fac-tory packaging, the date shall be recorded on the Wear Time and Inspection Record and on the garment label.The ACPG Wear Time and Inspection Record format and instructions can be found in NSTM Chapter 470, Sec-tion 5. Results shall be recorded each time the garment is removed from, or placed, in it’s resealable storage bag,laundered or inspected. A separate record shall be kept for each ACPG item (i.e., one for each coat and one foreach pair of trousers.) Laundry personnel shall assign a laundry mark to each garment to facilitate matching itwith it’s own storage bag and Wear Time and Inspection Record. A label with numbered spaces for recording thenumber of times it has been washed is provided in each ACPG item. Laundry personnel shall place a check markin the lowest remaining numbered space in indelible ink prior to washing the ACPG item and shall enter thelaundering date in the Wear Time and Inspection Record. Prior to laundering, each ACPG item shall be inspectedfor the following conditions and replaced, if:

1. the 120 calendar date has expired,

2. the item has been worn more than 45 days,

3. the item has come in contact with petroleum, oil, lubricant or cleaning solvents,

4. the item is damaged, or

5. the item has been laundered 6 times.

655-3.7 LAUNDRY CHEMICALS

There are two different types of laundry chemicals authorized for use aboard ship; granular powder and solidcake. Solid cake chemicals were approved for shipboard use in May, 1997 and are intended to eventually replacegranular powdered detergents on all afloat units.

655-3.7.1 Powdered Detergent/Oxygen Bleach. Detergents sometimes are referred to as synthetic detergents orsynthetic soaps. The term synthetic, in its broadest sense, refers to the synthesis (building up) of materials to forma product different from natural substances. The powdered detergent to be used in washing all shipboard cotton,synthetic and blended fabrics, and wool blankets, is that stocked in the Federal Supply System and procured inaccordance with Navy Clothing and Textile Research Facility Purchase Description NCTRF/PD11-85A of 23 July1986. Nicknamed″Two-Shot″, the detergent is low in phosphate (which may degrade the fire retardancy treat-ment at higher concentrations), is low sudsing and also contains an oxygen bleach which will not harm coloredclothing. ″Two-Shot″ is equally efficient in hard seawater and soft water and is effective in hot or cold water.″Two-shot″ can be either manually dispensed by adding directly to the wash wheel prior to the start of the for-mula or automatically dispensed via the formula control unit by adding the chemical to the appropriate automaticsupply bin.

655-3.7.2 Sour. In addition to the powdered detergent-bleach required for use on all Navy Wash formulas, alaundry sour (blue) is also required. A laundry sour (blue) is an acid that is safe to use on fabrics. It should beadded to the last rinse by adding the chemical to the appropriate automatic supply bin and dispensed via theautomatic formula control unit. Sour neutralizes remaining alkalies (reduce Ph level) and dissolves iron and othermetallic salts which cause rust or a yellow discoloration. If left in fabrics, an alkali causes odors and discolora-tion after drying. Also, if the sour blue is omitted from the laundering process, itching and discomfort is likelyto occur, particularly when working in areas with a high ambient temperature, due to the high Ph level of theclothing. Use of a sour in the last rinse also removes sodium bicarbonate, which normally is in rinse water; evenwhen all the alkalinity is rinsed out, sodium bicarbonate remains. It is not injurious to fabrics, but when subjectedto the heat of flatirons, presses, and flatwork ironers, it is converted to sodium carbonate, which is quite alkalineand can cause injury to fabrics when in sufficient concentration and contribute to itching and discomfort. Sour-

Page 92: NAVAL SHIPS’ TECHNICAL MANUAL - · PDF filenaval ships’ technical manual chapter 655 laundry and dry cleaning this chapter supersedes chapter 655r1 dated 28 feb 1998 distribution

ing also decomposes any oxidizing bleach left in a load, prevents discoloration, and helps to sterilize the clothes.In addition, sour sets acid dyes often used in bright colored fabrics, and preserves the tensile strength of fibers.Sours also remove rust stains.

655-3.7.2.1 Sour may cause chemical burns if it comes in contact with eyes or skin, or if swallowed. For skincontact flush with water. For eye contact flush eyes with water for 15 minutes and contact medical personnel. Ifswallowed accidentally contact medical personnel immediately. For specific first aid treatment refer the productsMaterial Safety Data Sheet (MSDS).

655-3.7.3 Solid Chemicals. The solid chemicals to be used in washing all shipboard cotton, synthetic andblended fabrics, and wool blankets, shall be similar or equal to ECOLAB Solid System III as approved by NavyClothing and Textile Research Facility ltr 3903 N3.PG of 09 Jan 97. The solid chemicals shall be similar in com-position to the powdered laundry chemicals. The solid chemical dispensing system consist of separate detergent,oxygen bleach and neutralizer (sour) and an automatic dispensing cabinet. The dispensing system is a state-of-the-art, computer controlled product dispenser which offers many benefits over powdered detergents. These ben-efits include reduced product cost, accurate computer controlled dispensing, reduced storage space requirements,reduced plastic waste generation and eliminates direct handling of chemicals.

655-3.7.4 Starch. Sizing or starch (instant, dry) usually is prescribed for cotton shirts, trousers, and coats anduniforms but is never used with synthetic or synthetic-blend fabrics or with work clothes. Starch is applied toclothing and linen to give them body, smoothness and an improved appearance. The sizing operation is normallyconducted with the sour operation during the final rinse step. The amount of sizing should be just sufficient togive the garment a pleasing body and feel without undue stiffness. Additional starch may be required on machineswithout manual operating capability due to a shorter than necessary rinse step required to achieve the desiredstiffness. Always accomplish the sizing operation at the low water level at approximately 120° F. Starching usu-ally is done in the washer; occasionally, however, small loads or a few pieces of laundry can be hand-dipped ina separate container.

655-3.7.5 Storage. Bulk laundry chemicals should be stored in a laundry storeroom in close proximity to thelaundry. Break-out laundry chemicals stored in the laundry should be kept to a maximum amount needed for aone week period. Powdered chemicals such as″Two-shot″, sour blue and starch should be covered and stored ina cool, dry space to prevent it from developing cakes and lumps.″Two-shot″ and sour blue can be broken upbefore use, however starch can not be used if it cakes due to coming in contact with moisture.

655-3.8 DRY CLEANING CHEMICALS

Perchloroethylene or″perc″ is the most prominent solvent used for dry cleaning. It is a clear, colorless andnonflammable liquid that has a sharp, sweet odor and evaporates quickly when exposed to air. It is an effectivecleaning solvent because it removes most stains and dirt from all types of fabrics. Perc should only be used whenit is free and clear of water, dirt, rust, oils, or other contaminants. Authorized shipboard dry cleaning solvent isthat stocked in the Federal Supply System and procured in accordance with ASTM-D4081, Standard Specifica-tion for Dry Cleaning Grade Perchloroethylene. Perc is a toxic chemical and has been declared a suspected car-cinogen, hazardous air pollutant, and ozone depleter.

655-3.8.1 Operating with Perchloroethylene. To operate safely with perc, all operators should be fullyacquainted with the flow of perc through a typical dry cleaning unit. At the start of the cycle the cylinder is filledwith clean perc from the base tank. From there it generally circulates continuously through the filter and backinto the cylinder. Periodically perc from the wash cycle may be run through the still for purification and returned

S9086-V4-STM-010/CH-655R2

655-82

Page 93: NAVAL SHIPS’ TECHNICAL MANUAL - · PDF filenaval ships’ technical manual chapter 655 laundry and dry cleaning this chapter supersedes chapter 655r1 dated 28 feb 1998 distribution

to the base tank. Some machines may be programmed to operate with a continuous distillation cycle. In the dry-ing phase, hot air evaporates the perc left on the garments. The solvent vapors are condensed and returned as aliquid to the base tank. Washing and drying are typically accomplished in the same piece of equipment in a″dry-to-dry″ process.

655-3.8.1.1 Washing-Extract Step. The first and most basic step in the dry cleaning process is placing the gar-ments in the cylinder of the dry cleaning machine. The door is then closed and the cycle begins by filling withthe solvent/detergent solution from the base tank. Here the clothes are subject to mechanical agitation in thesolution. This causes both water-soluble and solvent-soluble soils to dissolve and insoluble soils and particulatesto disperse. At the end of the wash cycle the solvent is drained from the cylinder. During the spin cycle, addi-tional solvent is extracted from the garments in order to help reduce subsequent drying time. The overall qualityof this process depends on a number of factors:

1. Detergent Charge. An efficient dry cleaning operation, capable of removing a wide range of soluble andinsoluble soils, requires careful control of the solvent/detergent/moisture ratio. Proper charge levels for mostdetergents can be determined by using a simple but effective test kit and may be controlled by a detergentmetering device. Moisture levels may also be controlled by means of several moisture control devices.

2. Cycle Time. Some soils are more easily dissolved or dispersed than others, and certain fabrics will free soilsmore readily. Experience with different soils and fabrics will help the operator adjust the cycle time to suit thespecific conditions of the load.

3. Mechanical Action. Generally, both soluble and insoluble soils are removed more quickly as the degree ofagitation is increased (although too much mechanical action can damage the garment being cleaned). Agita-tion is determined by the design of the cylinder, the speed of rotation, and the amount of solvent in themachine. In particular, a load of garments that is less than the machine’s recommended capacity will receivegreater agitation than one that meets or exceeds the manufacturer’s recommendation.

4. Solvent Temperature. The solubility of most soils is related to the temperature of the solvent. In particular,partially soluble and gummy soils dissolve more quickly as the temperature increases. A balance must bestruck, however, because too high a temperature may soften resin binders causing coloring to disperse and mayalso raise the solvent relative humidity to levels (80% or higher) where garment damage can occur. Ideal sol-vent temperature, therefore, is between 75° and 80° F. This can be controlled by a solvent cooling device inthe dry cleaning machine.

5. Solvent Cleanliness. Clean perc is needed if garments are to be returned clean. Filters and stills, when prop-erly maintained, will keep the solvent clean. You can tell how effective these are by visually inspecting theperc. The perc should be a clear, colorless liquid free from suspended particles.

655-3.8.1.2 Drying Cycle. The drying process removes any solvent remaining in the clothes following thewashing-extraction portion of the dry cleaning process. Different types of loads will require different dryingtimes. Several factors in drying must be controlled to insure an efficient drying cycle:

1. Load Size. Overloading the cylinder slows the flow of warm air through the wheel. This slows the evapo-ration of the perc from the clothes.

2. Airflow. Warm air is blown through the cylinder to evaporate the perc and dry the clothes. Since the flowof air is affected by the amount of lint on the lint filter, this filter should be cleaned frequently. Lint build-upon the condensing coils can also restrict airflow, so these coils should also be checked regularly and accumu-lated lint cleaned off.

3. Cylinder Temperature. The best temperature for the warm air that flows through the cylinder is about 140°F.

S9086-V4-STM-010/CH-655R2

655-83

Page 94: NAVAL SHIPS’ TECHNICAL MANUAL - · PDF filenaval ships’ technical manual chapter 655 laundry and dry cleaning this chapter supersedes chapter 655r1 dated 28 feb 1998 distribution

If the temperature is much cooler, some clothes may not be dried completely. If the temperature is muchwarmer, wrinkles may set and some temperature-sensitive fabrics may experience degradation.

4. Condenser Temperature. A condenser is used to recover perc vapor from the air as the clothes are dried.Liquid perc is returned to the base tank, and the air is cycled again through the clothes for further drying.

655-3.8.1.3 Filtration. Filtration is an effective and economical method of clarifying solvent for re-use. Inoperation, the solvent flows from the outside of the filter through a paper filtering medium to remove particulatematerial and then through an activated carbon bed to remove some types of dyes that may bleed. When it is doneproperly, the solvent returned to the cylinder will be pure enough to meet the requirements for quality cleaning.A properly equipped and operated filter system can remove most insoluble soils, such as earth, sand, dust, lint,ashes, hair, and various kinds of pigments and dyes. As soil accumulates on the surface of the filter cartridge, therate of flow of the solvent through the filter decreases. Filters must be changed before they become overloadedin accordance with the manufacturer’s recommendation. Filter waste must be handled and disposed of as hazard-ous material.

655-3.8.1.4 Distillation. Distillation is a method used to reclaim and recycle perchloroethylene. This is a pro-cess in which used or impure solvent (perc which contains an excessive amount of solvent-soluble non-volatileresidues, such as fatty acids, grease and oils) is heated to the boiling point (250° F) and vaporized. Since impu-rities boil at a higher temperature than perc, they are left behind in the bottom of the still as sludge. Perc vapors,now free of impurities, pass through a riser to a condenser where they are liquified into a solvent/moisture mix-ture. Before the solvent can be returned to the storage tank, the water must be removed. This is done in a waterseparator, a simple but highly effective device. When a solvent/water mixture is passed through the water sepa-rator, the water, which is lighter than the solvent, rises to the surface and can be drawn off. The heavier solventflows under the baffle and is drained from the other side of the water separator. The distilled and dried perc isreturned to the storage tank for re-use.

655-3.8.1.4.1 Foul odors or off-odors in the solvent can be carried over into the cleaned garments. In most cases,odor-causing soils removed from the garments are trapped in the filter or the still. Odors that persist in the dis-tilled perc, however, may be a sign that the still is not operating properly. The still should be run at a tempera-ture no higher than the boiling point of perc (250° F) to prevent the odor-causing compounds from boiling anddistilling with the solvent.

655-3.8.2 Safety and Health Considerations. When proper safety precautions are observed, perc can be stored,handled and used safely. At the same time however, it is important to understand the hazards associated with perc.The most current and detailed information on health effects, handling procedures and first aid is contained in theMaterial Safety Data Sheet (MSDS) for the product. The MSDS should be posted in the dry cleaning space andmade available for inspection by all personnel. All operators and maintenance personnel must be thoroughlytrained on the information provided in the MSDS.

655-3.8.2.1 Routes of Exposure. Toxicity is the capability of a substance to produce a harmful or adverse effecton a living organism at some level or frequency of exposure. Exposure to perc may occur through inhalation,skin contact, eye contact and ingestion. The possibility and degree of exposure can be minimized by using properengineering controls, ventilation equipment and personal protection equipment such as gloves, goggles and res-pirators.

655-3.8.2.1.1 Inhalation. Breathing solvent vapor is the most likely route of exposure to perc, and it is essen-tial to keep atmospheric levels in the workplace below the permissible exposure limits and minimize exposure at

S9086-V4-STM-010/CH-655R2

655-84

Page 95: NAVAL SHIPS’ TECHNICAL MANUAL - · PDF filenaval ships’ technical manual chapter 655 laundry and dry cleaning this chapter supersedes chapter 655r1 dated 28 feb 1998 distribution

all times. There may be considerable variation in the subjective response of different individuals when exposedto perc. A response to different exposure levels may vary with the length of exposure and likely with the physi-cal condition of the individual. Exposure to perc vapor concentrations within the permissible exposure limitsshould not result in any known adverse effects. The presence of solvent vapor in the air can produce an odor.Although odor itself is not an acceptable measure of vapor concentration it can warn of a condition that requiresfurther investigation

655-3.8.2.1.2 Skin Contact. Perc is not likely to be absorbed in acutely toxic amounts through the skin. Fre-quent daily contact with perc can defat the skin and cause inflammation, but occasional brief skin contact is notlikely to produce any significant adverse effects. If perc is confined to the skin (e.g. under clothing) so that it cannot evaporate, severe irritation, even a burn may result. For frequent or prolonged contact wear gloves with apermeability suitable to the degree of contact.

655-3.8.2.1.3 Eye Contact. Undiluted solvent splattered into the eyes will produce slight to severe eye irrita-tion, and possible transient and reversible corneal injury. Although no serious injury is likely, exposure can causeextreme discomfort. Under routine conditions, use safety glasses or their equivalent. Contact lenses are not rec-ommended. Where liquid splash contact is possible chemical goggles should be worn.

655-3.8.2.1.4 Ingestion. The least likely route of exposure is ingestion, or swallowing perc. There is little like-lihood of ingesting perc when handling it properly in the dry cleaning plant. Intentionally swallowing largeamounts of perc however, could result in serious injury or death.

655-3.8.2.2 Effects of Exposure. The extent of any health effects from perc exposure depends on the concen-tration of perc and how long the exposure lasts. People exposed to high levels of perc vapors, even for brief peri-ods, may experience serious symptoms. The initial effects of overexposure may cause adverse effects includingnose and eye irritation, fatigue and headaches, and anesthetic and narcotic effects such as lightheadedness, diz-ziness, mental dullness, and loss of coordination. Exposure to continual and extremely high vapor concentrationsmay cause severe depression of mental functions, respiratory failure, unconsciousness and even death. Concen-trations capable of causing serious acute effects such as unconsciousness may be expected only in exceptionalcircumstances such as working in inadequately ventilated confined areas or bending over a large pool of spilledperc without the proper protective equipment. Daily overexposure, whether voluntary or accidental, to concen-trations causing dizziness or other more serious side effects may produce liver damage and respiratory failure.The cancer-causing potential of perc has been extensively investigated. In laboratory studies, perc has been shownto cause cancer in rats and mice when they swallow or inhale it. There is also evidence suggesting a possiblecasual association between perc exposure and elevated risks of certain types of cancer. As with all health effects,the potential for an increase of cancer depends on several factors including how much perc exposure there is,how often the exposure occurs, and how long it last. Also, important is the way the exposure occurs, as well asthe individual’s overall state of health, age, lifestyle, and family traits.

655-3.8.2.3 Reducing Exposure. When perchloroethylene is used and handled properly by trained personneland equipment is operated and maintained properly, it should present little or no practical hazard to personnel. Atlevels below current exposure limits perchloroethylene is unlikely to produce any adverse effects, even fromrepeated exposure. Prevention and control of perc vapors can accomplished by proper maintenance of equipmentto avoid leaks, immediately cleaning up any leaks or spills, ensuring an adequate supply of fresh air through thearea and ensuring all equipment ventilation, especially exhaust ventilation, is functioning properly and in goodcondition.
