Abstract: This work investigates the influence of rotor spinning process parameters on the twist difference values of 100% polyester rotor spun yarns. Eight different types of opening roller, four different types of polyester spun fibre, two levels of yarn number, and two levels of opening roller speed were employed during the yarn spinning trials. Twist difference values of yarn samples were statistically evaluated using the full factorial design technique. Variance analysis results affirmed that fibre type and opening roller type are significantly influential parameters for the twist insertion efficiency of 100% polyester rotor spun yarns.
