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.
