Development And Property Research Of Combed Cotton/Apocynum Venetum Wrapped Yarn

Apocynum venetum has already attracted widely attention in the textile industry applications. But it is greatly difficult to develop pure textile product with apocynum. Currently, general process is to put it blended with cotton, but blended fibers are hardly fully functional and do little or nothing to solve the wearing comfort issue, which reduces the special natural effects of apocynum to some extent and hinders the promotion and use of apocynum, as well as its products.In this article, we use wrapped spinning technology to make combed cotton yarn wrapped in a spiral form on the surface of apocynum yarn, forming combed cotton / apocynum wrapped yarn. Because of the wrapped yarn have the advantages of hairiness, evenness, twist shrink, strength and fluffy yarn body, make up the shortcomings of yarn quality, and improve its yarn breaking strength and evenness, enhance its wear resistance, reduce yarn hairiness, so that the wrapped yarn has apocynum’s functionality, also has the appearance of cotton.This paper mainly includes four parts. In the first part, the development of the new spinning technology, the application and research actuality of wrapped spinning, the purpose, significance and research content of this paper were summarized. The second part introduces the mechanism of wrapped spinning and the HKV141 D wrapped spinning machine, and briefly describes the performance of apocynum and the wrapped spinning process selection. The third part mainly researches the basic properties of wrapped yarn and the fabric style of wrapped yarn fabric. In the fourth part, using a series of orthogonal analysis to optimize the spinning process parameters, the optimal process parameters can be known, and verified by experiments.The experimental results show that through the wrapped spinning process effectively improve the quality of apocynum yarn, and significantly improved the wearability of apocynum, while ensuring the premise of apocynum’s unique properties. Create a new way for the development and use of low quality apocynum yarn, and for the subsequent weaving provides high-quality, multi-grade apocynum yarns.
