Splicing of Jute Yarn by the Wrapping Method

Abstract

Splicing by the wrapping method has been studied for jute yarns spun on flyer and wrap spinning systems. Load-elongation properties of the spliced yarns are affected by the splicing duration and length, but not by the splicing materials. Splicing by the wrapping method produces a very strong joint in flyer as well as wrapped spun yams, particularly at increased splicing lengths, and strength retention increases to a similar extent. While the flyer spun yam registers higher elongation retention, after splicing the wrapped spun yam shows higher work of rupture at each splicing length. Because the thickness of a splice is much less than that of a knot (dog knot), the spliced yarn causes significantly lower tension fluctuations during weaving than the knotted yarn.
