三组分壳聚糖纤维赛络集聚纱的纺制

Spinning of Three Components Chitosan Fiber Siro Condensed Yarn

探讨莫代尔/珍珠改性粘胶/壳聚糖55/30/15 9.8tex赛络集聚混纺纱的纺制工艺。通过介绍莫代尔纤维、珍珠改性粘胶纤维、壳聚糖纤维的性能特点,采用包混和条混的混和方式,分别制成壳聚糖纤维纯纺预并条和莫代尔纤维珍珠改性粘胶纤维混和预并条,再经过三道混并制成符合混纺比要求的熟条。对各工序纺纱工艺参数进行了优化配置,采用赛络集聚纺纱技术,成功纺制出赛络集聚混纺纱。认为:壳聚糖纤维硬并丝多,纯纺生条较困难,要采取特殊的前纺工艺流程;细纱工序要及时清洁网格圈,合理选用钢领和钢丝圈,才能使产品质量达到较好水平。

Spinning process of modal/pearl modified viscose fiber/chitosan fiber 55/30/15 9.8 rex siro condensed blended yarn was discussed. Properties of modal fiber,pearl modified viscose fiber and chitosan fiber were introduced. The blending method of package blending and silver blending was adopted. Pure chitosan fiber pre-drawing silver and modal fiber pearl modified viscose fiber pre-drawing silver were spun respectively. Drawing silver that can satisfy blending ratio demand was finally produced after three times drawing. Technology parameters in each spinning process were optimized and configured. Siro condensed spinning technology was adopted. Siro condensed blended yarn was successfully spun. It is considered that chitosan fiber is stiff with much string. It is difficult to spin pure silver. Special pre-spinning process need to be used. Lattice apron in spinning process should be cleaned in time. Ring and ring travler need to be reasonable selected, then higher quality level of product can be achieved.
