Performance characteristics of mercerized ring- and compact- spun yarns produced at varying level of twist and traveller weight

Abstract

The performance characteristics of ring- and compact-spun yarns have been compared at varying level of tex twist factor, yarn linear density and traveller weight. It is observed that the ring yarns are comparatively softer due to the lower flexural rigidity. On the other hand, compact-spun yarns perform better in respect of abrasion resistance, tensile strength, knot strength, loop strength and breaking extension. The loss in tensile strength is higher when the yarn is looped as compared to that when the yarn is knotted; however, in both the cases the loss is found to be marginally lower for compact-spun yarns. Further, the effect of mercerization on all these characteristics of both the yarns is found to be more pronounced in compact-spun yarns and the yarns spun at low twist factors.
