普适性柔顺光洁纺纱技术分析与应用

欧洲采用优化工艺、外加强制性控制力的方法降低纱线有害毛羽,最有效成熟的集聚纺技术降低细纱3 mm毛羽高达80%,但存在能耗大、成纱硬度高等问题。针对现有技术问题,本文提出在线降低纤维刚度以提高纤维加捻成纱性能的纺纱方法,研制出配套纺纱技术装备,制造出表层致密光洁、内部纤维充分转移的柔顺光洁纱线,形成柔顺光洁纱线技术,广泛适用于棉、麻、化纤纺纱领域,具有装备操作简便、性价比高、易于推广等方面的优势,实现产业化应用。

An Analysis on a Novel Staple Spinning Technology and Its Applications

European-developed spinning technologies usually reduce harmful hairiness by optimizing process and employing extra-mandatory control over the fiber assembly. The most sophisticated compact spinning technology can reduce 3-mm hairiness by as high as 80%. However, there exist problems such as high energy consumption and high rigidity of the spun yarn for pneumatic compact spinning. To overcome these problems, this paper develops a novel soft and smooth spinning technology to improve staple spun yarn properties by reducing fiber rigidity online; relevant equipment of this novel spinning technology is also developed to produce soft and smooth yarn with compact smooth surface and sufficient fiber-migration inner-structure. As the novel soft and smooth spinning technology has advantages such as easy operation, low energy consumption, excellent performance of eliminating hairiness, it has been widely and industrially applied to cotton, ramie and chemical staple fiber spun yarn production.
