Effects of Fiber Properties of Acrylics on Rotor Spinning

Abstract

An investigation is reported to determine which of the differences in properties of commercially available acrylic fibers are most important in influencing rotor spinning performance and ultimate yarn quality. A crushing test appeared to be a successful method to isolate the differences between acrylic fibers and to predict their processing behavior, Fiber damage and rotor deposit build-up were assessed when different acrylic fibers were spun, and some similarities were found between spinning behavior and yarn properties and the results obtained from the crushing test. Consequently, the different behavior of the fibers during rotor spinning was defined by the differences in fiber characteristics.
