Abstract: The influence of ply twist and plying technique on the properties of OE rotor yarns spun from acrylic and viscose fibres has been studied. It is observed that the tenacity, abrasion resistance, unevenness and hairiness of OE rotor-spun yarns substantially improve after plying. The two-for-one plied yarns produced using the same processing conditions are weaker by 3-13%, more extensible by 6-22%, more even by 2-7%, less twist lively by 12-22%, more hairy by 9-26% and have 2-5% lower abrasion resistance than the ring plied yarns in both twisting techniques. Increasing the ply twist factor increases the tenacity, abrasion resistance and twist liveliness but decreases the hairiness of plied yarns. The properties of the fibrous material and draw-off nozzle also affect the quality of OE rotor-spun plied yarns.
