Examples of Four Point System Inspection in Apparel Industry

Fabric Inspection System:
The inspection is 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 point system inspection, ten points system, and Graniteville system, and so on. But there is no facility for identifying the shade, handle, and bias of the 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:

Four Point System Inspection in Apparel Industry

4 Points System:
In this method, defective points are found out in 100 square yds. of fabric by inspection. The fabric must be rejected if the defective 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 the defective 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

Points / 100 sq. yards,

……….Total defected points          ….. …..100                  ….. 36”
= ……………………………………………  ×  …………..×…………………………………….
………….Total fabric length                     …..   ………Inspected fabric width

……….26               100          36”
= ……………….×………….×…………
………120                1             48”

= 16.25 (ANS)

The fabric roll is held or hung at the back of the machine. Then the fabric from the roll is pulled over the glass of the inspection table and is wound in another role placed in front of the machine. Fabric unwinding from one roll and wound in another is done by motor or by manually. Arrangement of light is done from the lower end of the glass of the inspection table. As a result, during the passing of the fabrics on the glass, if there are any defects in fabrics, they can easily detect and marked right away.
