Abstract: Accelerated needle wear when using rotor spun yarn rather than ring spun yarn is an unresolved problem faced by the knitting industry. Rotor spun yarn provides numerous advantages; but the economic disadvantage caused in the form of the accelerated needle wear is a great impediment to its popularity. Various unsuccessful attempts have been made to find the reason behind this phenomenon. Many parameters like yarn twist, yarn count, wax levels were considered by other researchers and were found not to influence the accelerated needle wear. The main objective of the study was to find the parameters that essentially contributed to the increased abrasiveness of the rotor spun yarn over ring spun yarn when they interacted with different metallic surfaces. The following aspects were studied: the tension variations of the yarns while passing over different metallic surfaces, the changes in resistance across the metallic wires when the yarns pass over them, the temperature differences observed on the metallic wire, caused by friction between the yarn and the metallic wire and the analysis of experimental findings is presented.
