4 Point Inspection

Per American Association of Textile Chemists and Colorists (AATCC), four point system, every 100 square yards allow at least 10 defects.  This standard can be checked in every authorized textile lab.

Four Point System for fabric inspection

A. Inspection quantity:

    1. If inspecting on the base of total yardage, inspection quantity: total      yardage 1/2 x 8

    2. If inspection on total package: inspection quantity = total packages 1/2

 

B.  Defeat evaluation *Four Point System*

    1. Point

        -Defect is 3 inches or less than deduct one point

        -Defect between 3 inches and 6 inches deduct 2 points

        -Defect between 6 inches and 9 inches deduct 3 points

        -Defect exceeds 9 inches, deduct 4 points

    2.Continuing defect, deduct 4 points for every yard

    3.Bigger defect (hole, etc., however big) deduct 4 points for every yard

    4.Continuing Slub mark, crease mark, uneven dye, less width, barer, etc. deduct 4 points for every yard.

 

C.  Points calculation

    1.Evaluation grade = total points x 36 x 100/ inspection yardage valid width (inch)

<40 for every 100 square yards' defect equal or less than 40: qualified (the fabric is acceptable)

    2.Reject

>40 reject (the fabric is rejected)
