Studies on characteristics of flyer and dref-3 spun jute yarns texturized by sodium hydroxide solution

Abstract

The tensile and bulk properties of texturized and texturized-steamed jute-acrylic dref-3 yarns as well as of texturized and mercerized jute-cotton dref-3 yarns have been studied and compared with those of the conventional jute untreated and texturized yarns. The percentage loss in tenacity, weight and bulkiness is found to be minimum for treated jute-cotton dref-3

yarns whereas flyer-spun jute texturized yarns show maximum bulkiness and loss in tenacity and weight. The tenacity, initial modulus, modulus ratio, specific work of rupture and packing coefficient values of dref-3 jute texturized yarns are higher than those of jute flyer- spun texturized yarns. A characteristic difference in the stick-slip pattern of failure is also

observed for parent and treated jute flyer-spun yarns as well as for parent and treated jute-acrylic and jute-cotton dref-3 yarns.
