To determine the effect of friction on yarn strength, researchers fitted a Lawson-Hemphill CTT yarn tester with a friction element to provide a value of the force required to break the yarn with or without a frictional load. Because of the drag induced on a yarn as it touches machine components in processing or testing, a yarn will break at a lower tension. The drop in strength for these samples due to the insertion of a friction element varied from 38-55 percent. Yarn strength testing with the addition of speed and friction is more indicative of yarn performance in a manufacturing environment. Certain yarns with a high single end break number and a high coefficient of friction will break in knitting or weaving before other yarns having a lower single end strength number and a lower coeficient of friction.
