摘要
探讨纯棉细号正反强捻纱绉织物织前准备工序的关键技术措施。针对CJ 7.3/7.3 327/327 170强捻绉织物生产过程中易出现纱线扭结、纠缠等问题,织前对纱线进行适当的热定形处理;整经采取"较大张力,适中速度"的工艺原则以及Z捻正装、S捻反装两种纱线安装形式;浆纱合理选择浆料配方,采用适中的上浆条件;穿综及穿筘采用合理的顺序及方法,确保经纱Z捻与S捻以2∶2顺序排列;最终使生产该种织物的织机效率达到75%～80%,满足了生产要求。
Key technology measures in preparation process of pure cotton fine S and Z hard twist yarn crepe fabric were discussed. Heat-setting was done on the yarn properly before weaving because problems of yarn easy kinky and winding would happen in producing CJ 7.3/7.3 327/327 170 hard twist yarn crepe fabric. In warping process,principle of larger tension and medium speed was adopted, S twist yarn was installed in clock wise and S twist yarn was installed in counter clock wise. Sizing instruction was selected properly in sizing process and sizing conditions were selected in mod- erate. Proper order and method were adopted in heddle draft and reed-in to ensure S twist yarn and Z twist order be 2 ： 2. Finally fabric loom efficiency can be reach 75% to 80% and production demand can be satisfied.
