Influence of fibre length and denier on properties of polyester ring and air-jet spun yarns

Abstract

The effect of polyester fibre length and denier on hairiness, abrasion resistance, flexural rigidity, co-efficient of friction and compressional energy of air-jet and ring-spun yarns has been studied. It is observed that the yarn hand in terms of flexural rigidity and compressional energy improves by using finer fibres in air-jet yarns. Increase in fibre length decreases

the yarn hairiness, abrasion damage and yarn-to-metal friction in both air-jet and ring yarns. Finer fibres decrease the hairiness and abrasion damage and increase the yarn-to-metal friction in both air-jet and ring yarns.
