Abstract

In this study, the possibility of manufacturing vortex yarns directly from card slivers having two different sliver counts is investigated. The fiber type, card sliver count, and yarn count are considered as the selected parameters to be examined due to their effects on unevenness, yarn imperfections, hairiness, breaking strength, and elongation properties. For this purpose, cotton and viscose yarns in three yarn counts, 14.77, 19.69, and 29.53 tex, were produced from two card sliver counts (3.58 and 4.92 ktex) by a Murata Vortex Spinning (MVS) system. The study revealed that vortex yarns can be produced by feeding directly card slivers to the MVS system, and resulting yarns have features compatible with those yarns produced on a conventional production line. In the context of this study, where the drafting process is eliminated, it is recommended to produce yarns from fine card slivers to reach a lower CVm% and imperfection value and to produce yarns by coarser card slivers to reach lower hairiness and higher Rkm values.
