Abstract

A study of the hairiness of rotor-spun yarns by means of the ITQT digital hairiness meter demonstrates the influence of the rotor geometry and other parameters on the hairiness of rotor-spun open-end-spun yarns from acrylic fibres. The rotor geometry influences yarn hairiness; the effect of twist is of little importance for man-made fibres, and the linear density of yarns influences the hairiness of rotor-spun yarns in a manner similar to that for ring-spun yarns.
