补充资料:摇纱
      把管纱或筒子纱重新卷绕成规定重量的绞纱的工艺过程。绞纱能打成体积小而紧密的包装,有利于运输和贮存,所以棉纱、绒线和绢丝常制成绞纱打包出售。绞纱结构松散,在染色或漂白时能使染料、漂白剂等均匀地渗透到纱线中,而且绞纱纱线中纤维较易自由回缩,使处理后的纱线显得膨松、柔软、富有光泽,因此绒线或色织的棉纱和绢丝等一般都摇成绞纱后进行染色或漂白。
  
  摇纱的过程是:纱线从纱管或筒子上退出,通过导纱杆和断头自停导纱钩卷绕到回转的纱框上。绕到一定圈数后,摇纱机自动停车,经人工分绞、扎绞,打结,松开纱框,取下绞纱。摇纱机的主要机构有:①纱框:卷绕纱线用,落纱时可折拢以便取下绞纱;②导纱装置:使纱线始终保持均匀的张力,有时还附加清洁装置,以除去部分杂质疵点;③分绞装置:使横动导纱钩在每绕完一小绞后移动一段距离,以分开各小绞;④满绞自停、断头自停装置和停车制动装置:能保证绞纱具有规定的长度或重量;⑤落绞装置:满绞后将绞纱由机尾回转支承中取出;⑥生头装置:在摇纱开始前能将纱线迅速嵌于纱框上,可以提高机器效率,减轻工人劳动强度。
  
  绞纱根据卷绕形式分为直绞式绞纱和花绞式绞纱两种(如图)。
  
  
  直绞式纱线呈平行卷绕,由数小绞扎成一大绞,多用于绒线。花绞式纱线呈交叉卷绕,横动导纱钩作短动程(50~76毫米)的往复运动,不分小绞,编绞费时较少,可提高机器运转效率,同时绞纱空隙多,染液容易均匀透过,绞纱不易紊乱,一般多用于棉纱和绢丝。绞纱重量要求十分严格,所以纱框长度必须精确,圈数也应准确。
