Spinning Conditions and Characteristics of Open-End Rotor Hybrid Yarns

Abstract

Combinations of different yarn components are useful for improving yarn structure and properties. In this research, we describe a new method of combining filament yarns and staple fibers on a modified open-end rotor spinning frame. By changing filament over-feed, we have produced three kinds of hybrid yarns while keeping spinning conditions for two kinds of hybrid yarns stable. Yarn structure, tensile properties, and irregularities significantly depend on the filament over-feed.
