纱线疵点产生原因分析

Cause Analyses of Yarn Defect

探讨电子清纱器工作过程中纱线疵点的分级和产生原因。介绍了纱线疵点的定义和分类,针对络筒清纱工艺,根据疵点纱的不同形状并参考细纱的基础直径,识别粗节纱和细节纱。结合纱线疵点分级区域,分析了纱线疵点频率分布图,指出了各个区域疵点可能产生的原因。认为:通过络筒电子清纱器的清纱数据,可以有效分析各个工艺环节出现的问题,帮助快速定位和解决质量问题,提高质量管理的效率。

The grading and cause of yarn defect in the process of electronic yarn cleaner were discussed. The definition and classification of yarn defects were introduced. Yarns with thick place and thin places were identified according to different shapes of yarn with defects and refering the basic diameters of yarn aimed at the cleaning technology in winding. Combined the yarn defect classifing area, the frequency distribution chart of yarn defect was analyzed, the possible causes of defects in each areas were pointed out. It is considered that the problems in each processing can be effectively analyzed through the yarn cleaning data from winding electronic yarn cleaner. The quality problems can be quickly positioned and solved, the quality managing efficiency can be improved.
