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:
“What more is necessary to make us a happy and prosperous people? Still one thing more … a wise and frugal government, which shall restrain men from injuring one another, which shall leave them otherwise free to regulate their own pursuits of industry and improvement, and shall not take from labor the bread it has earned.”
—Thomas Jefferson (1743–1826)
“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)
