QUALITYQuality means customer needs is to be satisfied. Failure to maintain an adequate quality standard can therefore be unsuccessful.

6

OBJECT OF QUALITY•To maximize the production of goods within the specified tolerances correctly the first time.

•To achieve a satisfactory design of the fabric or garment in relation to the level of choice in design, styles, colours, suitability of components and fitness of product for the market.

7

If we want to produce high quality garments, we need high quality piece goods.  When a sewing factory receives fabric from the mill, it is difficult to conduct a full 100% inspection of the fabric. so we are require to inspection all of fabric due to make a good quality of garments.

Size of Defect:3 inches or less = 1 point penaltyOver 3 inches but not over 6 inches = 2 point

penaltyOver 6 inches but not over 9 inches = 3 point

penaltyOver 9 inches = 4 point penalty Note: a maximum of 4 points should be charged

to one linear yard.  Also, note that only "major" defects are charged.

Quality control by 4 point system

10

The acceptable score varies.  Many companies use 40 points per 100 yards as acceptable defect rate.  However, others may find this not acceptable...

 Here is some math to show you an example. Total Yardage received: 5400Acceptance Point-count:  40 per 100 yards·         Total Yards Inspected : 540·         Total penalty points found in the sample inspection: 150 points 150 divided by 540 times 100 = 27.77 points per 100 yards 

(because the allowance is 40 points per 100 yards, this shipment would be acceptable).

Flow Chart of Garment Inspection

* In Sample making section

* In- Marker making section

* Inspection in fabric spreading section

* Inspection in fabric cutting section

* Inspection in fabric sewn section

* Inspection in pressing & Finishing section

The various step of garment manufacturing where in-process inspection and quality control are done are mentioned below-

15

Quality Control in Sample Section: 

* Maintaining buyer Specification standard* Checking the sample and its different issues* Measurements checking* Fabric color, gsm, Fastness etc properties required checking* Spi and other parameter checking

16

Quality Control in Marker Making: 

•To check notch or drill mark•Fabric width must be higher than marker width•Fabric length must be higher than marker length•Matching of green line•Check pattern size and dimension•Matching of check and stripe taking into consideration•Considering garments production plan•Cutting table length consideration•Pattern direction consideration

17

Quality Control in Fabric Spreading: 

•Fabric spreading according to correct alignment with marker length and width

•Maintain requirements of spreading

•Matching of check and stripe

•Lay contains correct number of fabric ply

•Correct Ply direction

•To control the fabric splicing

•Tension control

•Maintain cutting angle

•More skilled operator using

18

Quality Control in Fabric Cutting: •The dimension of the pattern and the cut piece should be same and accurate

•Cut edge should be smooth and clean

•Notch should be cut finely

•Drill hole should made at proper place

•No yarn fraying should occur at cut edge

•Avoid blade deflection

19

Quality Control in Sewing Section: 

•Input material checking•Cut panel and accessories checking•Machine is in well condition•Thread count check•Special work like check•Needle size checking•wrinkle appearance control

•Stitching fault should be checked•Garments measurement check•Seam fault check•Size mistake check•Matching of trimming•Shade variation within the cloth•Wrong placement of interlining

20

Quality Control in Finishing Section: 

*Water spot*Shading variation check*Smooth and unfold in pocket*In secured or broken chain or button*Wrong fold*Proper shape in garments*Properly dried in after pressing

*Wanted wrinkle or fold in lining*Get up checking*Collar closing*Side seam*Sleeve placket attach*Cuff attach*Bottom hem*Back yoke*Every parts of a body

SWEING THREADAlmost all garments produced have one component in common; the sewing. The Bellow quality are required to control when using thread.

A zipper, zip, or zip fastener, is a commonly used device for temporarily joining two edges of fabric

Following Factors are Considered in Zipper:

Proper dimension of zipper The top and bottom end should correctly sewn The tape and color of zipper should be uniform Slider has to be locked properly The slider should move properly
