The Structure and Properties of Open-End Yarns

Abstract

A comparative study of the structure of open-end (OE) and ring-spun yams from cotton and man-made fibers has been carried out in this paper. It is shown that the effective length of fibers in yarn as represented by the "fiber spinning- in coefficient" is significantly lower in OE yams than in ring yams. In OE yams, fibers migrate in a different way, and the mean fiber position and amplitude of migration are lower than those in conventional ring yams. Preferential migra tion of component fibers generally observed in ring yams is considerably lower in OE yams, and the fibers are more homogeneously distributed across the yam cross section. The significance of these findings to the behavior of OE yarns in processes like swelling, singeing, etc., is also discussed.
