Blended Yarn Analysis: Part I-Influence of Blend Ratio and Break Draft on Mass Variation, Hairiness, and Physical Properties of 15 Tex PES/CO Blended Ring-Spun Yarn

This study was undertaken to investigate the effect of P/C blend ratio and break draft on yarn quality and physical properties. 15 tex yarn samples were spun from three blend ratios, i.e., P/C 30/70, 50/50, and 70/30 at ring frame with six break drafts (1.35, 1.38, 1.42, 1.45, 1.49, and 1.53). The results of blend ratio were analyzed through linear regression technique to predict correlation between two variables. Strong correlation observed between blend ratio and yarn quality and physical properties, as the share of polyester increased all yarn characteristics improved. Prominent improvement in yarn mass variation and hairiness was observed when polyester percentage increased from 30% to 50% whereas tenacity and elongation improved more remarkably when polyester share increased to 70% from 50%. Most of the yarn characteristics were found optimum at break draft 1.49.
