影响整经浆纱断头的因素分析

Analysis of Factors Affecting the Broken Ends of Warping and Sizing

为了降低整经、浆纱断头率,提高织造生产效率,以集聚纺CJ 9.72 tex纱为例,分析原纱细节处强力偏小、弱捻纱、毛羽纱及筒纱接触压力、卷绕张力设置、大吸嘴负压设置等对筒纱质量的影响及控制措施;通过试验对比优选钢丝圈号数、锭速及络筒线速度,提出锥形纸管质量要求及设备管理、操作管理要点。指出:影响织布厂整经、浆纱的断头因素较多;合理设置电清工艺参数和筒纱张力,严格控制车间温湿度,减少弱捻纱及成纱毛羽,优选器材和专件,严控锥形纸管质量,加强设备运行状态管理,做好清洁工作和异常筒纱处理等,可以提高成纱质量、减少不良品质筒纱的产生。

In order to reduce the broken ends rate of warping and sizing and improve weaving production efficiency,taking compact spinning CJ 9.72 tex yarn as an example,the influence of small strength in fine ends of the original yarn,soft twist yarn,hairiness yarn and contact pressure winding tension setting of cheese yarn and negative pressure setting of large suction nozzle on cheese yarn quality and its control measures are analyzed.Through experiments and comparisons,the number of traveler,spindle speed and winding speed are optimized,and the quality requirements of tapered paper tube,equipment management and operation management points are put forward.It is pointed out that there are many factors that affect the broken ends of warping and sizing in the weaving factory.Reasonable setting of process parameters of electronic yarn clearer and cheese yarn tension,strict control of workshop temperature and humidity,reduction of soft twist yarn and yarn hairiness,optimization of accessories and parts,strict control of tapered paper tube quality,strengthening equipment operation state management,and do a good job in cleaning and abnormal cheese yarn treatment can improve yarn quality and reduce the generation of cheese yarn with poor quality.
