Introduction
A product must satisfy the consumer in terms of beauty, attractiveness, taste, shape, design and longevity of depending on the type of product.
A product devoid of quality has no demand among consumers and as such has no salability. So it is very necessary for every company to establish quality check or quality assurance department in the industry.
This assignment helps me to understand inspection methodology for sewing, finishing, and packing, help me to evaluate various production processes. It also helps me to source information and to collate, evaluate and manage it, communicate clearly and succinctly in both oral and written form.

Quality & Quality Inspection
Quality:
Quality is an ideal, a condition of excellence. Product quality is based on a product attribute. User-based quality is fitness for use, manufacturing based quality is conformance to requirements, value based quality is the degree of excellence at an acceptable price.
ISO 9000:2000 Define it is “degree to which a set of inherent characteristics fulfill requirement.”
Quality inspection in apparel industries:
Quality inspection is done to control quality of garments. Checking of fabric, sewing thread, button, stitch, zipper, garments size etc according to required standard or specification is known as inspection. Quality inspection is important for every section of apparel industries.
There are three steeps in apparel industries to control quality, i.e.
1. Raw Material Inspection;
2. In Process Inspection;
3. Final Inspection;
Raw Material Inspection:
Fabric, sewing thread, button, trims, interlining, labels, tags quality check is done in raw material inspection steep.
1. Fabric Inspection:
Normally fabric inspection is done through Fabric Inspection machine. It is very important for every industries check fabric before cutting. In fabric inspection their checks several things i.e. in fabric are there any defect available or not. In fabric, fabric defects viz. off shad or shade variation, hole in fabric, barre effect etc. can be visual after entering into the store room. For those defects it will be problem able for making garments making. In fabric inspection there also check fabric strength, color, quantity, bayous. To check fabric there are different system i.e. 4 point system, 10 point system etc.
2. Sewing Thread Inspection:
During stitching fabric frequently brakeage of sewing thread is one of the great problems for garments manufacturing. So that it is necessary to check thread construction, sew ability, color, imperfection, finish, package density, winding, yardage of sewing thread.
5
In thread construction thread number, thread ply, thread balance, thread tenacity, thread elongation, number of twist is necessary to check.
3. Trims & Accessories check:
Button, interlining, label & tags are also need to check so that quality can be maintain according to required quality. For button, button strength, button color, quantity etc are check.
In Process Inspection
Inspectioning different parts of garments before sewing are called in process inspection. It starts from marker making, than fabric spreading, fabric cutting, fabric sewing, pressing or finishing checking is done in process.
Marker Making:
For some marker fault quality of garments can be lower, i.e.
It is necessary to check all the parts of garments pattern are in marker.
In marker labeling or coding of pattern should be check
Pattern direction should be check.
The entire pattern are sated correctly should be check.
Pattern grain line is very important thing which must be considered during marker making.
During marker making every pattern pieces dimension should be accurate.
During marker making fabric length and width should be consider.
Fabric Spreading:
For those fault which effect garments quality occurs during fabric spreading and should be consider is given bellow;
During fabric spreading it should be spread according to marker length and width and fabric alignment should be correct in both sides.
Fabric should not be spread so tight or loose.
During fabric spreading because of uneven tension in fabric bias or bowing can be create.
Fabric must be spread in proper way so that fabric wastage can reduce.6
It should be consider are there any static electricity problem is available or not.
Fabric ply must be spread correctly
Fabric Cutting:
For high quality garments high quality cutting is necessary. To control fabric cutting quality good there must be consider some things;
Pattern dimension and cutting parts dimension is same or not.
Cutting parts edge how much smooth and clear.
Are there any parts add with other parts because of fusion problem.
Notch mark cutting is done accurately.
Drill mark is placed correct position & size or not.
Shorting/ Bundling:
It is necessary to check numbering, shorting, and bundling is done accurately.
Fabric Sewing:
In garments industries most large & important section is sewing section. In this section it is necessary to check all the machine operators’ work. In this section some common faults and problems must be considered, these are;
1. Sewing defects:
Needle damage;
Skipped stitch;
Thread breaks;
Seam pucker;
Wrong stitch density;
Uneven stitch;
Staggered stitch;
Improperly formed stitch;
Oil spot or stain.7
2. Seaming defects:
Uneven width;
Fault stitch line;
Back stitch must be given properly;
Twisting;
Check or strip matching;
Seam matching;
Wrong stitch face side or back side;
Thread color shade variation.
3. Assembly defects:
If finished component does not accurate size.
Garments do not accurate in size.
If any design skip to join.
Component is not joining in right place.
If lining is tight or loose.
If parts direction is wrong.
4. Pressing or Finishing:
Fabric burn or burn spot attach with body.
Any types of water spot.
Color shading occurs because of hot ironing.
Button is insecure or broken.
Garments are folding accurately.
Pocket is pressed smoothly and except fold.
Garments shape is accurate.
8
Those things are plays important role that have to be check during in process.
Final Inspection
In final inspection generally inspect fully complete garments. Before final inspection there has no chance to check complete garments. It is important from the buyer to finally check. In final inspection normally garments size, form fitting, fabric faults are check.
Size:
For size, it is check according to what size is written in size label.
Shirt inspection check list
No Location Inspect for
01 Collar Both points are same or not, strip or check is match accurately, stitch, collar flat or not.
02 Size Size label is in correct place, and every parts size is correct or not.
03 Button & button hole Placed in right place or not, evenness of gap between one button to other, stitch is done correctly, are there any broken button or not.
04 Pocket Pocket upper edge horizontal or not, pocket position, size, stitch, stripe or check is match, flat or not.
05 Hem Stitch, are there any puckering occur or not, edge free from stitch.
06 Yoke & shoulder Stitch, puckering problem, skipped stitch.
07 Side seam Pattern matching, stitch, free from raw edge
08 Cuffs Strips or check matching, top stitch, flat or not.
09 Finished appearance Threads edge comes out or not, are there any oil spot or not, fabric fault, color matching, strip matching.
Packing: Before packing it is necessary to check fabric is free from broken needle. It is also need to check packing raw material is free from making any problem in garments and after packing it is packed accurately.
