Abstract

Studies on the relationship of yam and fabric parameters to finished fabric performance have led to the development of an empirical expression of stitch tightness, a dimensionless quantity which includes such variables as stitch loop dimen sions and yam diameter. Rapid laboratory testing methods were developed to determine the value of this proposed constructional density factor concept. These two tests were shown to have good correlation with actual wear perform ance. Laboratory and confirmatory wear testing have determined the minimum constructional density factor for various knitted fabrics. These factors can be used to calculate the greige yarn run-in required in knitting to engineer fabrics that will have acceptable performance in wear.
