针织纱的动态力学性能研究

Study of the dynamic mechanical property of the knitting used yarns

阐述了美国劳森-谱希尔公司生产的CTT纱线性能测试仪的测试原理、方法、条件和试样准备,使用该测试仪测试了不同线密度、不同捻度、不同纺纱方法纺出的针织纱的动态力学性能,由测试结果得出:纱线的线密度、捻度、断裂强力和纱线的纺纱方法均对纱线的动态强力有着较大影响。

This paper introduces the testing principle,method,conditions and sample preparation of the American Lawson company produced CTT yarn property tester,and tests the dynamic mechanical property of the knitting used yarns with different linear density,different twist and different spinning methods.It can be concluded that the yarn's linear density,yarn's twist,breaking strength and spinning method will all influence the yarn's dynamic strength remarkably.
