Description

Vortex spinning blending covering yarn

Technical Field

The invention relates to the field of vortex spinning, in particular to vortex spinning blended core-spun yarn.

Background

With the continuous progress of society, textile technology and textile equipment are continuously developed, new yarns are continuously appeared, and vortex spun yarns are one of the most attractive yarns. Vortex spinning is a new technology in the existing spinning system, compared with the traditional ring spinning: the method has the characteristics of short spinning flow, high production efficiency, online quality monitoring, high automation intelligent degree and the like, and also has the advantages of greatly reducing labor, reducing yarn hairiness and the like. Therefore, the vortex spun yarn is processed into needle and cotton fabrics, and has the advantages of smooth cloth cover, less hairiness, good wear resistance, good fuzz and pilling resistance, bright color, moisture absorption, quick drying and the like. At present, the vortex spinning technology is researched a lot at home and abroad, but the research on the linear performance of the vortex spinning is less.

The vortex spinning process and the blended fiber structure can be used for spinning various functional yarns. For example, when a human body sweats in summer with high temperature and high humidity, the fabric can cling to the human body after absorbing moisture, and gives a sticky, pasty and not refreshing feeling. The existing improvement modes generally aim at improving the fabric structure, and the improvement on the yarn structure is rarely seen. The vortex spinning process can produce the core-spun yarn with a composite structure, and the structure and the performance of the yarn can be improved so as to realize better yarn performance.
