络筒的作用有哪些?

络筒作为织前准备的首道工序,它的目的是将来自纺部的管纱或绞纱在络筒机上加工成符合一定要求的筒子。同时络筒还是纺纱的最后一道工序,在纺织领域中的作用更可谓是重中之重。

那么,它的作用都有哪些呢?

1.改变卷装,提高纱线卷装的容纱量:
将容量较少的管纱(或绞纱)通过络筒连接在一起,形成一个容量比较大的筒子,而一只筒子的容量与二十多只管纱相近。筒子可用于整经,并捻,卷纬,染色,无梭织机上的纬纱以及针织用纱等。这些工序不能直接使用管纱,否则会使停台时间太长,生产效率会降低,产品质量的提高也无法得到保证,所以通过络筒使卷装容量提升是提高下一道工序生产率和质量的必要条件。
2.清除纱线上的疵点,提升纱线质量:
棉纺厂生产的纱线上无法避免地存在一些疵点和杂质,比如一些粗节,细节,双纱,弱捻纱,棉结等。络筒工序中利用清纱装置来检查纱线,清除纱线上的疵点和杂质,来避免它们对织物的质量造成影响;同时还能提高纱线的均匀度和光洁度,以利于减少纱线在后道工序中的断头,提高织物的外观质量。纱线上的疵点和杂质在络筒工序被清除是最合理的,因为在络筒工序中每只筒子的工作是独立进行的,当某一只筒子在处理断头的时候,其它筒子可以继续工作,而丝毫不受影响。
