Comparative assessment of Eli-Twist and TFO yarns

Abstract

An attempt has been made to compare the properties of Eli-Twist yarn with those of conventional TFO yarn. Yarns of three compositions (100% Polyester, 50/50 Polyester/Cotton and 100% Cotton) were produced on Eli-Twist and ring spinning systems. Three different counts (39.4tex, 29.5tex and 23.6tex) from each composition have been produced, maintaining 40 twist factor for all the yarns. Hairiness, tensile strength, breaking extension, diameter, abrasion resistance and coefficient of friction have been measured and then compared with those of conventional ring-spun TFO yarn. The mass irregularity and imperfections are found more or less similar in both the yarns, while Eli-Twist yarn exhibits higher breaking strength and breaking extension. Both coefficient of friction and abrasion resistance of Eli-Twist yarn are found to be low as compared to ring- spun TFO yarn.
