摘要

A comparison of the ring- and compact-spun yam properties have been made along with the effect of extension rate and specimen length on tenacity and breaking elongation. The compact yarn is stronger and extensible than ring yarn. For both yarns, tenacity increases with increase in extension rate at 200 and 500 mm specimen length. But for 50 and 100 mm specimen length, tenacity increases continuously with the extension rate for compact yarn whereas in case of ring yarn, tenacity increases with increase in extension rate upto 200 mm/min and thereafter decreases. Breaking extension follows the same trend as that of tenacity with extension rate and gauge length. Also, the compact yarn have less hairiness and irregularity than ring yarn but have better abrasion resistance and dye uptake. Further, the compact yarn is more rigid and densely packed than ring counterpart but optical diameter is less than that of ring yarn.
