摘要
为了顺利纺制水溶性维纶11.8 tex纱,针对该纤维的性能特点和用户对成纱异纤的严格要求等条件,开清棉工序采取"小定量、低速度、勤抓取"工艺,以减少纤维损伤,保证成卷质量;梳棉工序采用"慢速度、多梳少打、勤转移"工艺,以减少棉结产生;并条工序采取"短流程、低速度"工艺,防止纤维条过熟;粗纱和细纱工序采用"低速度、小后区牵伸、大后区隔距"的工艺原则;络筒工序掌握"小张力、低速度"的控制原则。同时严格控制各工序温湿度和异纤,最终成功纺制出水溶性维纶11.8 tex纱,其成纱质量满足了使用要求。
To spin water-soluble PVA 11.8 tex yarn successfully,the fiber properties and user demands to yarn foreign fiber were considered fully. In opening and picking process, processing of less weight per unit, lower speed and more catch were adopted to reduce fiber injury and ensure lap quality. In carding process, processing of lower speed, more carding,less beating and more transfer was selected to reduce neps. In drawing process,processing of shorter process and lower speed was adopted to prevent fiber sliver disorder. In roving and spinning process, process of lower speed, less draft in back zone and larger gauge in back zone were selected. In winding process, processing of less tension and lower speed was selected. At the same time, temperature ＆ humidity and foreign fiber in each process were controlled strictly, finally water-soluble PVA 11.8 tex yarn can be spun successfully, the yarn quality can reach use demands.
