Description

In order to improve yarn strength and to diversify yarn structure, a multi-core twin spun yarn made by using the experimental ring-spinning frame was produced. The tensile properties and the thickness variation of various core twin spun yarns were examined, and the effects of insertion of core filaments into a twin spun yarn made from two different types of staple fibers were discussed. It was found that the insertion of multi-core filaments was accompanied by the fasciation of some staple fibers in the yarn andthe prevention of irregular drafting in the almost-twistless zone from front roller nip to strand convergence point.
