涤纶/粘胶/棉 三组分 MJS纱线开发及纱线性能的研究

本论文先对新型纺纱技术进行大致的介绍，然后重点介绍了我们将要使用的喷气纺纱技术，并对喷气纺纱技术的国内外现状、发展趋势、工作原理等一一作了总结报告。研究本课题的意义是通过对喷气混纺新纱线的开发，探索与实践怎样在喷气纺纱机上开发新的混合纱线，再通过研究新纱线的价值得出喷气纺纱技术的前景和它在我国纺织行业的适用性。
本试验是用涤纶、粘胶、棉三种纤维在MJS喷气纺机上进行混合纺纱的纺制，目的是开发出一种新型纱线，并找出开发纱线的特性和价值。我们对开发的纱线进行了条干、毛羽、耐摩擦性等性能的检测，并与传统纱线做了简单的对比。
文章内容主要分为五个章节，第一章介绍了新型纺纱技术的种类以及国内外喷气纺纱技术的发展现状；第二章介绍了MJS喷气纺纱机以及纺纱机理；第三章介绍课题使用的三种纤维原料和纱线开发的前纺工艺，以及MJS混纺纱线开发的过程；第四章是对开发出的纱线性能的分析；第五章讨论了开发出纱线的应用领域并对课题做了总结。

Abstract
First，the new spinning system was introduced on this paper roughly，then we introduced mainly the jet spinning system. The summary report including the situation of jet spinning system at home and broad, development trend and operating principles also were completed in this paper. We started this research to design and produce new jet blended yarns in air-jet spinning machine through the development of new jet blended yarn , then we could predict the prospect and applicability of the new spinning system in china textile industry through the study the value of such new yarn.
In this experiment, we mixed and spun polyester, viscose and cotton to produce a new jet blended yarn in MJS jet spinner and find the development characteristics and value of this new yarn. Furthermore, we tested the evenness, hairiness and abrasion resistance of this new yarn and had a brief comparison between this new yarn and conventional yarn at the same time.
The content of the article is mainly divided into five chapters. In the first chapter，the new spinning technology and the present situation of air-jet spinning system at home and broad were introduced. The second chapter introduced the MJS jet spinning machine and spinning mechanism. The third chapter introduced the three fibers, the drewing process and the MJS development process. The fourth chapter is about the properties of the new yarn. The fifth chapter discussed the application of the yarn and made a summing-up report.
Key words: new type spinning system  air jet spinning system  yarn properties  MJS   mechanism
