配棉与精梳前纺工序对精梳机工作质量的影响

Impact of Cotton Assorting and Fore Spinning Process on Performance of the Combing Machine

为了减少纱线中的疵点及毛羽,提高成纱的条干均匀度与光洁度,从配棉、清梳联及精梳准备工序讨论了精梳工艺,重点分析了精梳准备工序的三种工艺效果,以条卷机-并卷机工艺最优,预并条-条并卷机工艺次之,预并条-条卷机最差。指出精梳纱质量不能单靠精梳机来完成,精梳棉条质量指标与精梳前纺工序工艺配置和配棉质量关系密切,而且和精梳准备工艺路线有关。因此,要提高精梳纱质量必须从配棉、前纺的每一个工序抓起。

In order to reduce the spoiled yarn and the hairiness for better evenness and finish of yarn, discussion is made on the combing process considering cotton assorting, blow-carding combination and the combing preparation. Highlight is given to the three processes involved with combing preparation. Lap formerlap doubler takes the first place, and predoubling machine-lap former and doubler combination taking the second place and predoubling machine-lap former taking the last place regarding the process. Conclusion is made that the quality of the combed yarn is not only dependent on combing machine, but also on process configuration in fore spinning process and cotton assorting, and the combing preparation process is indispensable. Conclusion is made that quality of the combed yarn is closely related to cotton assorting and processes in fore spinning.
