2.5维机织物接结经纱缩率的影响因素

由于高性能纤维成本较昂贵，在织造织物前对其纤维用量的计算显得尤为重要。基于2-2带衬经结构的层-层正交角联锁织物结构优势，织造了10种不同规格参数的织物，测试其接結经纱的缩率，分析纬纱密度、纬纱线密度、织物层数和接結经纱本身的线密度对接結经纱缩率的影响。研究发现，纬纱密度和线密度对接結经纱缩率影响非常明显，而织物层数和接結经纱本身的线密度对接結经纱缩率影响不明显。用测试得出的接結经纱缩率分别对10种织物的纤维体积含量进行计算，与称重法得出的纤维体积含量值吻合得很好，为实际生产工艺中计算高性能纱线的用量提供了较好的参考。

Experimental research on influential factors of binder warp shrinkage of 2.5-D woven fabric

Due to the high costs of high performance fiber,it is important to determine fiber consumption before manufacture.As the advantages of 2-2 layer-layer orthogonal angle-interlock fabric with lining,ten different kinds of fabrics were woven and the binder warp shrinkages were tested to analyze the influence of weft count,weft fineness,fabric layers and binder warp yarn fineness on the binder warp shrinkage.The results showed that weft fineness and weft count have remarkable effect on binder warp shrinkage,and fabric layers and binder warp yarn fineness have little effect.Also,the fiber volume fraction was calculated with the tested shrinkages,the data was coincident with the results of weight method.Results of this experiment provide a reference for calculating the fiber quantity in production.
