Characteristics of dref-3 yarns with jute in core

摘要

The tensile properties of jute-acrylic and jute-cotton dref-3 yarns with jute in core have been studied. The tenacity of dref-3 yarns was found to be lower but the strength translation efficiency of jute fibres was higher when used in the core of jute-acrylic dref-3 yarn as compared to that when used in the flyer yarn structure. Stick-slip pattern of failure was observed in case of dref-3 yarns, whereas catastrophic failure was observed in case of jute flyer yarn. Breaking elongation and specific work of rupture of the dref-3 yarns were higher than those of the jute flyer yarn.
