Abstract

The phenoinenon of twist loss in open-end staple spun yarns has been explained by the slippage between Fiber ring and rotor wall and the reaction to turning moment during twist insertion. In the present study some variables such as: blend composition, twist multiplier, yarn count, staple length and fineness of fibers were chosen to explore the twist efficiency of rotor cotton/polyester blended yarns. The experiments were carried out by varying two variables at different levels and three variables 3³ factorial design technique. The results declared that twist efficiency was found to be influenced significantly by O.E C/P yarn parameters. In addition to the above parameters, the two factor interaction such as Blend composition with twist multiplier and blend composition with yarn count affect significantly the twist efficiency. Also, it has been shown that there is a strong correlation between twist loss and fiber blend parameters.
