纯棉特细紧密纺双绉织物的生产体会

Production Experience of Pure Cotton Superfine Compact Crepe De Chine Fabric

探讨纯棉特细紧密纺双绉织物的生产技术要点。针对织物在织造过程中易退捻扭结的问题,对强捻纱在织前准备工序进行了定形处理,整经张力偏大控制,浆纱采用"中浓低黏、中压力、重浸透、求被覆、双浆槽、适当降低上浆率、少用或不用PVA"的工艺路线,织造时合理调节上机张力、开口工艺、引纬工艺等参数。结果减少了强捻纱易扭结所造成的疵点,使织机效率达到95%,顺利开发出2 000捻/m纯棉特细紧密纺双绉织物。

Production technology key points of pare cotton superfine compact crepe de chine fabric were discussed. According to yarn kinky problems in weaving, hard twist yarn was set in weaving preparatory process. Warping tension was controlled slightly larger. The special processing was adopted, including middle concentration and pressure, lower viscosity, re-soaked, covered and double size box, reducing sizing percentage appropriately, using less with or without PVA. In weaving process, loom tension, shed processing and weft-inserting processing were adjusted properly. Finally defects caused by hard twist yarn can be reduced, loom efficiency can be reached 95% ,2 000 twist per meter pure cotton superfine compact crepe de chine fabric can be produced successfully.
