摘要

In the production of bulked yarn from jute and shrinkable acrylic blended yarn by heat provoked method, it was observed that the relatively stiffer fibre jute forms the outer surface of the bulked yarn due to migration. In the present study a third component non-shrinkable synthetic fibre has been incorporated to improve upon the handle properly of the bulked yam. The physical properties of the bulked yarns have been studied. It has been found that shrinkage due to bulking of the ternary blended yarns is between 24 and 28. The specific volume of the ternary blended bulked yarns is much similar to the binary bulked yarns. Bulking reduces breaking tenacity and increases breaking extensibility of the ternary blended yarn. The specific flexural rigidity of the ternary blended bulked yarns is substantially lower than the binary blended bulked yarn. The yarn composed of viscose rayon as third component in the blend is found best in the ranking order on subjective assessment of handle property of the ternary blended yarn.
