Determination of warp cover factor

Updated: Sep 14, 2023

What is Cover Factor?

Cover factor is a scientific measurement of the percentage area of the fabric covered by the yarns and fiber. In other words, the test establishes cover factor by recording a specific amount of light that passes through the gaps in the fabric.

Numerical Example:

A cotton fabric is made from 22Ne warp and ends per inch is 60. Determine the warp cover factor.


Two consecutive ends are shown in the above Figure.
