Fabric Inspection System
The inspection are done to control the quality is means by examining the products without any instrument. To examine the fabric, sewing, button, thread, zipper, garments measurement and so on according to specification or desired standard is called inspection. There are a number of systems to inspect the fabric. For example, four points system, ten points system, and Graniteville system and so on. But there is no facility of identifying the shade, handle, and bias of fabric. Only Four points system is granted by AAMA (American Apparel Manufacturers Association) and AAQC (American Association of Quality Control) and that is why widely used for fabric inspection and described below:
 Fabric inspection system
4 Points System:
In this method, defected points are found out in 100 square yds. of fabric by inspection. The fabric must be rejected if the defected points are greater than 40.

 Defects length for warp way and weft way Points Up to 3 inch 1 3” – 6 “ 2 6” – 9” 3 Above 9” 4

 Defects area for holes and openings Points 1 “ or less than 1” 2 Above 1 “ 4

Note:
It must be remembered that, defected point must not be more than 4 in each yard.

Example:
For 100 square yards inspection.

 Effects length No. of faults No. of points Up to 3 inch 10 10×1 = 10 3” – 6 “ 5 5×2 = 10 6” – 9” 2 2×3 - 6 Above 9” 0 0×4 = 0 Total = 26
