摘　　要：细纱离不开牵伸,牵伸器材的性能和工效是实现完美牵伸的关键。从DTM139高速化细纱机牵伸控制的特点出发,论述了优选牵伸控制器材是实现重定量大牵伸工艺的必要条件,探讨了软弹性胶辊在牵伸中的控制作用,并通过工艺对比试验,介绍了不同的胶辊在不同的工艺生产条件中的应用方法和效果,从而帮助用户在正确的牵伸理念下,根据该设备特点,合理选配加长型上销、圆弧型密齿罗拉、多台阶下销、YJ20-142弹簧摇架和重定量工艺,达到最大化纺纱效益的目标。Spun yarn cannot be separated from drafting. The performance and work efficiency of drafting equipment are keys to the achievement of the perfect drafting. Starting from the drafting features of DTM139-high speed ring spinning frame, this thesis explains that optimal selection of drafting equipment is a necessary condition on which we can realize the program ＇big ration-big drafting＇. Here, it focuses on the control effect of soft elastic cots in drafting process and introduces the application method and effect of different cots under different production conditions by process contrast test. Thus, with correct drafting concept and according to features of the equipment, users can select longer top cradle, arc-shaped and fine-toothed roller, multiple terraced nose bar, YJ20-142 spring pressure arm and heavy- ration Drop：ram to maximize the benefits of spinning.
