where is the Twist Multiplier, also known as or the Twist Factor.

In the case of ring spun cotton yarns, for example, the following values of K have been found to give the best results.
Warp yarns, 35's and less 4.75 Warp yarns, 35's to 80's 4.50 Warp yarns, 80's to 110's 4.25 Filling yarns, medium numbers 3.50Read more about this topic: Twist Per Inch
