Abstract

In this study, the compact-spinning cotton yarns with a liner density of 9.72 tex were knitted by the tricot warp-knitting machine. The mechanical properties and hairiness index of cotton yarns through different parts were tested and the reasons for their variation were analyzed. In addition, they were compared with the same fineness of ring-spinning combed cotton yarns. The results demonstrated that the cotton yarns’ breaking strength decreased continuously after passing through the warp-knitting machine, decreased by 25.4% relative to the original yarns. The hairiness index of cotton yarns rose through the guide rail and tension lever, increased by 42.0% and 74.3% respectively compared with the original yarn. However, the hairiness index decreased by 16.4% when cotton yarns passed through the guide needles relative to the previous process. It is concluded that compact-spinning cotton yarns were more suitable than ring-spinning combed cotton yarns for warp knitting.

摘要

在本研究中，采用经编机编织的密纺棉纱的衬密度为 9.72 tex。对棉纱通过不同部位的力学性能和毛羽指数进行了测试，分析了其变化的原因。此外，它们还与相同细度的环锭精梳棉纱进行了比较。结果表明，棉纱通过经编机后断裂强力持续下降，较原纱下降25.4%。棉纱毛羽指数通过导轨和张力杆上升，比原纱分别提高42.0%和74.3%。但棉纱通过导针时毛羽指数较前道工序下降16.4%。
