Combination Effects of Open-End Rotor Spun Hybrid Yarns

摘要

We have developed a mechanical hybrid yarn spinning system that produces different yarn types on a modified open-end rotor spinning frame. In order to improve yarn properties and produce novel yarns, we investigate the effects of combinations with typical hybrid yarns by inserting two filament yarns with varying filament over-feeds. The results are a new rotor spun loop (RSL) yarn made by combining two aspects of typical hybrid yarn production into one process, and an RSL yarn where a filament yarn, fed with a core filament over-feed (CFOF), is located in the center of one yarn and the other filament yarn, fed with the effect filament over-feed (EFOF), makes a loop on the yarn surface. The stable conditions of RSL yarn production are within a range of EFOF ≧ 4 (m/min) and -6.0 ≦ CFOF ≦ -4.0 (m/min).
