In the industry the number of twists per inch is calculated as:
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:
“It is while we are young that the habit of industry is formed. If not then, it never is afterwards. The fortune of our lives therefore depends on employing well the short period of our youth.”
—Thomas Jefferson (1743–1826)
“The reason American cars don’t sell anymore is that they have forgotten how to design the American Dream. What does it matter if you buy a car today or six months from now, because cars are not beautiful. That’s why the American auto industry is in trouble: no design, no desire.”
—Karl Lagerfeld (b. 1938)
