What are the four standards for the inspection of clothing fabrics?

Four-point standard of clothing fabric inspection;

One point: the defect length is less than or equal to 3 inches.

Two points: the defect length is more than 3 inches and less than 6 inches.

Three points: the defect length is more than 6 inches and less than 9 inches.

Four points: the defect length is more than 9 inches.

The quartile calculation formula is:

Average penalty 100 square yards = (total penalty X 100 X 36)/ total number of yards checked x specification width (inches).

Unless the fabric specification is wrong, the invisible defects on the surface will not be scored and the small defects will not be recorded.

It is not allowed to exceed 4 points in a code, and any continuous defects are evaluated with 4 points, such as poor size and holes. Like crosspieces, color differences, narrow widths, folds, ramps and even incomplete fabrics, they are all calculated at 4 points/yard.

Extended data:

Principle of defect scoring:

A, all warp and weft defects of the same code shall be deducted by no more than 4 points.

B for serious defects, each code defect will be rated as 4 points. For example, all holes and holes will be rated as four points regardless of diameter.

C For fabrics with continuous defects, such as crosspiece, edge-to-edge color difference, narrow seal or irregular width, crease, uneven dyeing, etc. , each code defect should be rated as 4 points.

D, within the selvage 1 ",no points will be deducted.

E, regardless of the warp and weft direction, no matter what the defect is, the correct score is given according to the defect score based on the principle of visibility.

F, except for special provisions (such as coating with adhesive tape), it is usually only necessary to check the front of the grey cloth.
