A Comparison of the Hairiness and Diameter of Ring and Open-End Yarns

Abstract

This paper presents a comparison between the hairiness and diameter of open-end and ring yams spun from various polyester/cotton blends. The yarn hairiness and diameter were measured using an optical technique. The study covered the effects of blend ratio, yarn count, and twist on the hairiness and diameter of open-end and ring yams. The results show that the yams spun on the BD 200 machine had a diameter roughly 10% larger than correspond ing ring yams. The open-end yarns were also found to be less hairy than ring yams, but the hairiness was found to have a higher coefficient of variation.
