Effects of Spinning Conditions on Structure and Properties of Open-End Cover-Spun Yarns

Abstract

Critical settings and their effects on the properties of open-end cover spun yams produced by a novel system are explained. The yams are constructed from open-end rotor spun (OER) yarns and textured polyester yarns combined within the yarn formation zone of the rotor during the open-end rotor spinning process. The end result is a textured yarn wrapped as a sheath around an OER yarn core, in which the wraps per meter distribution is uniform, the yarn remains soft, and tensile properties are better than for an equivalent OER yarn.
