Abstract: The effects of polyester fibre denier, tex twist factor and yarn composition on the properties of polyester-viscose rotor yarns spun at higher rotor speeds and ring yarns have been studied. It is observed that twist loss is minimum for polyester-minority rotor yarns spun from 1.0 denier fibre and it increases with the increase in tex twist factor and rotor speed. The tenacity and breaking extension are considerably lower for polyester-viscose rotor yarns than for ring yarns. The tenacity of all the yarns hardly changes with the variation in tex twist factor and rotor speed but it increases with the increase in fibre fineness and polyester fibre proportion. Polyester-majority rotor yarns possess larger diameter than the ring yarns. The diameter decreases with the increase in rotor speed and tex twist factor. An increase in tex twist factor, rotor speed and polyester fibre content offsets the evenness.
