牛奶蛋白纤维/PTT/羊绒混纺纱的生产实践

Production of milkfiber/PTT/cashmere blended yarn

针对3种纤维的品质特性,充分发挥3种纤维的优点,开发了牛奶蛋白纤维45%/PPT/45%羊绒10%的混纺针织纱。结合新品开发生产实践,对影响牛奶蛋白纤维混纺纱半精纺纺纱工艺和工艺配置的因素进行了研究和探讨,优化了纺纱工艺参数,着重强调了提高产品质量的技术措施。并对牛奶蛋白纤维、PTT、羊绒混纺针织纱和纯羊绒针织纱成品质量指标进行了对比。

The blended knitting yam is composed of milkfiber 45%, PTT 45% and cashmere 10%. On the basis of the development of new production, this paper discusses the technics of blended yams and semi-worsted spinning, in terms of the primary characteristics of three kinds of fibers, optimizing technological parameters of spinning and emphasizing the technic instruments to improve production quality. It also contrasts the quality index of the blended knitting yam composed of milkfiber, PTT and cashmere and the pure cashmere knitting yam finished product.
