where is the Twist Multiplier, also known as or the Twist Factor. This Twist Multiplier is an empirical parameter that has been established by experiments and practice that the maximum strength of a yarn is obtained for a definite value of K. 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
Famous quotes containing the word industry:
“Whatever I may be, I want to be elsewhere than on paper. My art and my industry have been employed in making myself good for something; my studies, in teaching me to do, not to write. I have put all my efforts into forming my life. That is my trade and my work.”
—Michel de Montaigne (1533–1592)
“You must, to get through life well, practice industry with economy, never create a debt for anything that is not absolutely necessary, and if you make a promise to pay money at a day certain, be sure to comply with it. If you do not, you lay yourself liable to have your feelings injured and your reputation destroyed with the just imputation of violating your word.”
—Andrew Jackson (1767–1845)
