Comparative study between100% cotton yarn & cotton-polyester blend yarn

Abstract

This study makes an assessment on difference in manufacturing of cotton yarn & cotton-polyester blend yarn. To undertake this study, the following three yarns were produced e.g.100% cotton yarn, 50/50 cotton & polyester blend yarn and 20/80 cotton & polyester blend yarn were produced. After that all the three yarns were tested for various parameters. It was observed that as the percentage of polyester increases the U% i.e. the irregularity in the sliver & roving decreases. For uniform blending of cotton-polyester more draw frame was required than that was required for 100% cotton process. In the roving frame it was possible to maintain higher flyer speed and lower twist for PC & TC. Between TC & PC the flyer speed was higher and twist was lower for TC than PC. It was observed that imperfections (IPI) decreased with the increase of share or % of polyester in the yarns. The yarn strength increases with the increase of polyester percentage in the yarns. Since the % of polyester is higher in TC therefore its strength was higher than that of PC yarns. Finally it was possible to maintain higher spindle speed and lower twist for PC & TC. Further to this
