Abstract: The influence of level of fibre finish in relation to total draft and spinning speed on characteristics of polyester MJS yarns has been studied. It is observed that different levels of fibre finish exhibit different trends at different drafts. A higher level of fibre finish significantly increases the tensile properties but adversely affects the flexural rigidity. Both yarn hairiness and abrasion resistance show an initial improvement followed by deterioration with the increase in fibre finish. Within the spinning speed of 150-210 m/min, the yarn evenness characteristics generally deteriorate with the increase in spinning speed, whereas the yarn tensile properties improve. The flexural rigidity shows a minimum at a spinning speed of 150m/min. The influence of total draft on tenacity, breaking extension, abrasion resistance, flexural rigidity and hairiness is similar to that of spinning speed.
