竹炭改性涤纶精梳棉混纺织物的开发

Development of Bamboo Charcoal Modified Polyester Combed Cotton Blended Fabric

探讨竹炭改性涤纶精梳棉混纺织物的生产技术措施。通过测试竹炭改性涤纶纤维的性能,分析竹炭改性涤纶精梳棉混纺纱的特点,指出:竹炭改性涤纶精梳棉混纺纱强力低、毛羽多,浆纱工序宜采用PR-Su浆料,遵循"小张力、小伸长、重加压、湿分绞、分层预烘、后上蜡、复分绞"的工艺原则;织造工序采用"大张力、早开口、小开口、中引纬、低后梁"的工艺原则,适当增大车间相对湿度。结果在喷气织机上成功生产了该织物,织机效率达到84%以上,产品质量达到了开发及生产要求。

Production technology measures of bamboo charcoal modified polyester combed cotton blended fabric were discussed. Properties of bamboo charcoal modified polyester fiber were tested, characteristics of bamboo charcoal modified polyester combed cotton blended yarn were analyzed. It is pointed out that the blended yarn strength is lower, the bairiness is much more. PR-Su size mixture should be adopted, processing of smaller tension and elongation, heavier pressure,wet lease,split-sheet predrying,later waxing and lease twice were adopted. In weaving process, processing of larger tension, earlier shed, smaller shed, middle weft-inserting, lower back beam were adopted, related humidity in work- shop was increased properly. Finally the blended fabric can be produced on the air jet loom successfully, loom efficiency can be reached above 84% , demands of production development can be reached.
