摘要
探讨化纤段彩纱生产时关键纺专器材的选配要点。针对化纤段彩纱生产过程中牵伸不开、缠绕胶圈、条干差等问题,分别从胶辊、胶圈和喇叭口的选配方面做了分析。指出:胶辊的选配应以中低硬度为宜,上涂料时需同时兼顾抗绕抗油性能,增加对纤维的握持,有效控制纤维;适当降低上胶圈的表面摩擦因数,减少饰粗纱因含量少、间歇式喂入等原因产生的绕胶圈现象;喇叭口应根据段彩风格来选配,前端尽量靠近胶圈钳口,从而改善条干水平。认为:优选纺专器材,合理调整牵伸工艺,能够改善化纤段彩纱可纺性,稳定产品质量。
The main points to select key accessory for chemical fiber segment-color yarn spinning were dis- cussed. Aimed at the problems of chemical fiber segment-color yarn spinning like draft difficulity,intertwining on apron, worse evenness and so on, the selections of rubber-covered roll ,apron and pipe socket were analyzed. It is pointed out that the rubber-covered roll with medium and lower hardness should be preferred. When coating mate- rial is added,the properties of intertwining resistance and oil resistance should be both combined to enhance the holding of fibers and control fibers efficiently. The surface friction factor of apron should be suitably decreased. The phenomenon of intertwining on apron caused by lower content batch-type feeding and so on of decorative yarn,should be reduced. The pipe socket should be selected based on the style of segment-color yarn,its front should be close to jaw of apron as much as possible, thus, the evenness level could be improved, It is considered that the spinnability of chemical fiber segment-color yarn can be improved and product quality can be stabilized by optimizing special spinning accessory and reasonably adjusting drafting technology.
