纺天丝纤维用胶辊胶圈常见问题探讨

为提高天丝纤维纺纱质量,介绍天丝纤维性能特点,所用胶辊、胶圈硬度、表面粗糙度Ra值的选择和使用周期管理。分析纺织企业纺制天丝纤维纱线时出现胶辊溶胀、成纱细节高、落纱再开车"吐粗纱"、不处理胶辊上车"黑印"等问题的原因,结合纺纱质量指标对比,提出针对性的解决措施。指出:纺天丝纤维用胶辊、胶圈的选型、表面处理方法选择及使用管理应根据具体情况分析处理,在使用过程中摸索、总结,才能充分发挥胶辊、胶圈的功能。

Discussion on Common Problems of Cots and Aprons for Spinning Tencel Fiber

In order to improve the spinning quality of Tencel fiber,the performance characteristics of Tencel fiber,and the selection of hardness and surface roughness Ra value and the management of service life of cots and aprons are introduced.Analysis is done to the causes of problems such as swelling of cots,high thin places of yarn,gush of roving ends when driving again after doffing,and non-treatment cots using with“black mark”when spinning Tencel yarn in textile enterprises.Combining with the comparison of spinning quality indexes,the corresponding solutions are put forward.It is pointed out that the selection of cots and aprons,the selection of surface treatment methods and the management of cots and aprons for spinning Tencel fiber should be analyzed and treated according to the specific conditions,and only in the use of the process of exploration and summary,can the functions of cots and aprons be fully developed.
