摘要
文章以细旦粘胶和锦纶6纤维为原料,在对其性能进行分析的基础上,对锦纶6纤维进行预处理并按比例将两种纤维预混以保证混纺比;优选纺化学纤维的针布,优化梳理工艺,在保证良好分梳、除杂的同时,尽量减少梳理过程对纤维的损伤;优化并条前后区牵伸分配、牵伸倍数等工艺配置,提高并条牵伸效果和熟条质量;适当增大粗纱捻系数,减少粗纱退绕时因意外伸长而断头的问题;细纱采用赛络集聚纺方式,加强对牵伸区浮游纤维的控制。采用以上生产工艺措施纺制的细旦粘胶/锦纶6混纺纱线,经测试,成纱强度高、条干均匀、棉结纱疵少,毛羽指标好,能很好地满足后道纺织加工要求和面料开发需求。
Taking fine denier viscose and PA6 fiber as raw materials,after analyzing each performance,the PA6 fiber was pretreated and then these two fibers are pre-blended in proportion to ensure the blending ratio.Selecting the card clothing for chemical fiber and optimizing the carding process to minimize the damage to fiber while ensuring good carding and cleaning performance during the carding process;the process configuration such as draft distribution and draft multiple in the front and back zones of drawing were optimized to improve the drawing effect and the quality of draw sliver;increasing the roving twist factor appropriately to reduce the yarn breakage caused by unexpected elongation during roving unwinding;the siro-compact spinning strengthens the control of the floating fiber in the draft zone.The test indicated that the fine denier viscose/PA6 blended yarn spun by the above production measures has high yarn strength,uniform evenness,fewer neps,and a good hairiness index,which can meet the requirements of textile processing and new fabric development.
