INTRODUCTION

Industrial attachment is an essential part of 4-years B.Sc. in Textile Technologycourse of southeast university . I had the opportunity to perform the industrialattachment with Jinnat Apparels Ltd. During 45 days long attachment, I studied theman, machines, material aspects of the circular knitting section, quality control section,planning section, grey fabric inspection section and finished fabric inspection sectionof the mill.I also had a short visit in the garments section of the factory. According tomy studies there I have prepared the following report and would like to present.

KNITTING SECTION

# Process definition:

Knitting is the interlocking of one or more yarns through a series of loops. Thelength wise columns of stitches corresponding to the warp in woven cloth are calledWales, the width wise rows of stitches corresponding to the weft are known as courses,weft knits are those fabrics in which the courses are composed of a single strand ofyarn. While warp knits are those in which the Wales are composed of single strands ofyarns. Gauge corresponds to the yarn count in a woven fabric and is defined as thenumber of needles or yarns, in ½ inches of cloth. The higher the gauges the morecompact finer the cloth.

# Process requirements:

In Jinnat Apparels Ltd. two types of machines are used for producing knittedfabric. These are –

1. Circular Single Jersey m/c.2. Circular Double Jersey m/c.

CIRCULAR KNITTING MACHINE

Circular knitting m/cs. are widely used through out the knitting industry toproduce fabric. This m/c can be built in almost any reasonable diameter and thesmall diameter of upto five, which are used for wear.

Machine for outerwear and under wear may vary from 12 inch to 60 inchin diameter according to manufactures requirement. This m/c can be used eitheras fabric or for making garments completely with fancy stitch. Latch needles arecommonly employed in all modern circular m/c because of their simple actionand also their ability to process more types of yarns.

Plain circular m/c uses only one sets of needles, circular rib m/c uses twosets of needles i, e, Cylinder needle and Dial needle, the interlock circularknitting m/c also uses two sets of needles by needles are long and shortrespectively for both dial and cylinder, that is why multiple design and thickfabric can be produce with that m/c. That m/c is also called double Jersey m/c.

M/c. Gauge – needle/inch (varies according to diameter) Needle Type – Latch Needle bed type – Single cylinder, Double cylinder, Cylinder &

Dial, long or short needles for cylinder and dial. Two principle operation exist:

1. English system – Where the cams and yarns strands revolve by needleand fabric take down is stationary.

2 American system – Where the needles and fabric take down revolvesby cams and yarn strands are stationary.

negligence.

7. Maintenance:

3 to 4 months gap between two maintenance.

25

METHODS OF INCREASING PRODUCTION

By the following methods the production can be increased –

1. By increasing m/c speed:Higher the m/c speed faster the movement of needle and ultimately production

will be increased.

2. By increasing the number of feeder:If the number of feeder is increased in the circumference of cylinder, then the

number of courses will be increased in one revolution at a time.

3. By increasing cam angle:By increasing cam angle production is increased.

4. By imposing automation in the m/c:a) Quick starting & stopping for efficient driving system.b) Automatic m/c lubrication system for smoother operation.c) Photo electric fabric fault detector.

5. By imposing other developments:a) Using creel-feeding system.b) Applying yarn supply through plastic tube that eliminates the

possibilities of yarn damage.c) Using yarn feed control device.d) Using auto lint removal.

26

CAUSES OF LOOP LENGTH VARIATION

1. Fluctuation in yarn variable:a) Due to count variation.b) Due to twist variation.c) Due to insufficient M.C. or M.R.d) Due to package hardness.e) If frictional property of yarn is not maintained.

2. Fluctuation in m/c variable:a) If temperature of the m/c is not standard.

b) If m/c gauge is not accurate.c) If m/c cam setting is not properly maintained.d) If needle timing and knock over is not accurate.e) If take down tension is wrong.f) If sinker timing is not correct.g) Improper yarn tension.

3. Robbing back:Due to 15% of yarn robbed back from old loop to newly formed loop.

27

CONTROL OF FABRIC QUALITY

Control of the quality of the cloth being knitted is the knitter mechanic’s majorresponsibility. Fabric set-ups and m/c maintenance, although necessary, must be putinto their proper order of importers. To set-up a fabric and run it on a well-maintainedm/c, when its quality is questionable, is senseless.

The mechanic must be able to diagnose a problem on a m/c and render animmediate cure. To do this, he must have a thorough knowledge of what causes adefect in fabric. When the cause is known, correction will soon follow.

FABRIC DEFECTS:Defects in circular knitted cloth fall into the following major groups: vertical

lines, barre, holes and snags, tuck or double stitches, these will be discussed seriatim.

Vertical lines:This defects can be caused by defective needles or defective trick walls. If the

trick walls are worn or not evenly spaced, the needles will knit at different speed. Thisuneven movement of the needles will cause uneven stitches which is turn can causevertical lines.

If a wall is too big for the needle, the needle will have a sideward motion, whichwill cause formation of a wide wale in the fabric. When the trick walls are not evenly

spaced, the needles will knit a certain points wide and narrow stitches in the fabric.These will also cause unsightly lines.

Dirt may often get into the tricks pushing the needles outwards (cylinder) orupward (dial) causing irregular vertical stitches. Bent and worn needles will cause thefabric to have wider Wales in certain places.

Needles with chipped latches, butts, hooks, cheeks, a protruding rivet or brokenspoons will cause fuzzy and irregular vertical lines. Needles with bent latches willcause vertical tears or ladders in the fabric. Too much lubrication or the use ofimproper needle oil often causes oil or dirt strakes.

28

Dark black vertical lines may be caused by dirty tricks, which cause the needlesto run high and rub against the cams. Not enough lubrication may also be the cause ofblack vertical lines.

Barre or uneven courses:

The following may cause these faults :1. Improper cam adjustment,2. Uneven yarn tension,3. Different yarn thickness or shaded yarn dyes,4. Dial not in even relationship to cylinder and5. Defective take down mechanism

With the use of positive feeding devices, the stitch cam adjustment isVery accurate. The most important thing to remember when adjusting stitch cams is tokeep the ratio of the dial stitch to the cylinder stitch the same at all the dial andcylinder feeds.

It must be remember that a positive feed system (tape) will feed the sameamount of yarn to all feeds regardless of stitch adjustment. This stitch adjustmentcontrols the tension only.

In the case of pique fabric or any similar kind, the odd feeds must be done at thesame tension, but the even form the odd feeds so long as they are all the same. Weknow now that the yarn tension will control the length of stitch.

It is very important that any surfaces that the yarn runs over or through mist beclean of any instruction which will caused irregular tension.

A defective takes down mechanism which pulls tight and then soft will cause areas on the fabric to be loose and tight. The take down mechanism must pull evenly at alltimes to maintain a fabric with even courses.

29

If dial is not in the proper relationship to the cylinder, fabric of uneven stitchlength will produced. The dial and cylinder relationship should be inspective at leastonce a year to maintain proper running conditions.

Uneven thickness of the yarn is one of major causes of barre. The mechanic isreally helpless in the situation. The only thing he can do is to learn to recognize thiscondition and notify the throwster immediately.

Badly wound yarn also will cause uneven tension. In most cases a positive feedsystem will eliminate this defect, but if one used the mechanic should have the yarnrewound. In the case of dyed yarn shaded the mechanic is helpless in such a situation,he must notify the throwster immediately.

Holes and Snags:

Holes in most cases are caused by excessive tension of the yarn. If stitch camsare adjusted too deep and there is excessive tension in the yarn, it wills beak, causing ahole. If the dial height is too high these will also cause a tremendous strain on the yarn.

Other factors that produce excessive tension on the stitch are as follows:1. Too tight a take down pup,2. The positive feed system operating improperly,3. Badly wound yarn,4. Yarn with thin or weak spots.5. Dirty or clogged surface in which the yarn passes through or on,6. Yarn warp around.

Snags in most cases are usually caused by badly wound yarn which ata low tensions and then suddenly jerks and runs at a high tension. This high tensionwills usually a line of holes from one to nine inches.

30

Drop Stitches:

This defect occurs when the needle tails to take new yarn of when the needlefails to take new yarn or when the needle losses its loop.

One of the major causes of this problem is an improperly set yarn carrier. If theyarn is not fed directly into the hook of the needle, there is a good chance that theneedle will not take the new yarn.

If the stitch cam is set too far back there will be too much yarn is the needleloop. Because of this loop will be so loose that it can fall causing a drop stitch.

Other possible causes of droop stitches are: the take down mechanism is tooloose, not enough tension on yarn, dial height too high, needles, yarn in wrong hole ofthe carrier, dial needle latch closing under yarn carrier and dial needle latch closingnear the hole of the carrier.

Tuck Stitches or Double Stitches:

This defect occurs when the needle does not cast off its old loop. In most casesthis defect can be traced to an improperly set stitch cam.

If the needle is not drown far enough back the old loop will remain on theneedle. On the other hand, if the stitch cam is set too far back, too much yarn will begoing to needle. In this case this needle will be unable to knock over such a large loop.

Other possible causes of Tuck Stitches are as follows:

1. Take down mechanism set too loose,2. Needles move too freely in their slots,3. Dial height set too low,4. Defective needles,5. Needle trick walls clogged with dirt etc.

CONCLUSION

College of Textile Technology has given me the field to perform the industrialattachment with Jinnat Apparels Ltd. This attachment seems to me as a bridge to

minimize the gap between theoretical and practical knowledge. Undoubtedly, thisattachment paved us the way to learn more about Textile Technology, industrialpractices, and industrial management and production process. Besides this attachmentgave us the first opportunity to work in an Industry and acquainted us with the internalsight and sound of Textile Industries. I believe with all these, the experience of theindustrial attachment will help our future life as a Textile Technologist.
