摘要
为促进棉纱在经编中的推广应用,测试了18.2tex纯棉精梳紧密纺棉纱在经编编织过程中经分纱筘、导纱针和编织后的经纱毛羽指数和断裂强度与断裂伸长率等。结果表明:经分纱筘、导纱针和经编织后的经纱毛羽指数先降后升;而断裂强度和断裂伸长率均一直下降,且织物中的棉纱力学性能显著下降,尤其是断裂伸长率下降35.80%,是影响经编顺利编织的主要因素。
For promoting the application of cotton yarn in warp knitting,the yarn hairiness index,breaking strength and elongation at break of 18.2 tex combed cotton compact spun cotton yarn in warp knitting weaving process were tested after raddle,guide needle and knitting.The results showed that the yarn hairiness index decreased first and then increased after raddle,guide needle and knitting,while the breaking strength and elongation at break decreasing all the time.The mechanical properties of the cotton yarn in the fabric decreased significantly,and especially the elongation at break decreased by 35.80%,which was the main factor affecting the knitting of the warp knitted fabric successfully.
