Wrapper Fibers on Low-Twist Worsted Yarns

Article Preview

Abstract:

This paper, by using Microscope Lecia M165, examines the surface structures of low-twist worsted yarns, which include three kinds of wrapped structures and two types of unwrapped structures. In particular, tight wrapper fibers have detrimental influences on yarn optical evenness, uniformity of dye take-ups, and handle. Combing Siro-spun feeding with the false-twisting spinning obviously facilitates the reduction of wrapper fibers on resultant yarns.
