How to calculate 4 point system in woven & Knit ?
is a standard method that is widely used in Textile and
Apparel Industries. In this system fabric quality is evaluated by penalty points per 100 square
yards.
Formula:
Points / 100 sq. yd. = (Total points in roll * 36 * 100)/ (Total length in yards * width in inches)
So, to evaluate fabric quality you need to know fabric width and length of the inspected roll or
thān. In case of woven fabric, length of the fabric roll is written on the Fabric roll tags. But knits
fabrics are sourced in weight and supplier does not mention length.
That's why when it comes to use 4 point system in knits fabric, inspector finds it difficult to use
given formula for calculating penalty points. To use the 4 point system for fabric inspection you
need to calculate length of the fabric in a roll/thān.
