聚酰亚胺纤维性能及其成纱性能
|
摘要
为研究聚酰亚胺纤维的性能及其品种适用性,文章对聚酰亚胺纤维进行各种表征及性能测试,探究聚酰亚胺纤维的可纺性。通过赛络纺纺纱工艺,分别纺制14. 8、19. 7、29. 6 tex三种纯纺纱线,并对三种纱线的表面外观、拉伸断裂性能、条干均匀度和毛羽指数等指标进行测试,探讨聚酰亚胺纯纺纱线的质量。研究表明:聚酰亚胺纤维表面光滑,截面呈不规则状;纤维大分子结构稳定,回潮率较低;比电阻数量级高;纤维的强力高,韧性好,可纺性好。但和普通合成纤维类似,纺纱过程中静电现象严重,在前纺阶段,应该对其进行油剂喷雾处理,防止静电现象。
In order to study the properties of polyimide fibers and the applicability of their varieties, some characterizations and performance tests for polyimide fibers have been done to explore the spinnability of polyimide fibers. And three kinds of yarns including 14. 8,19. 7 and 29. 6 tex were spun through the Siro spinning process. In order to explore the quality of pure polyimide yarn,the surface appearance,tensile fracture performance,evenness and hairiness index of the three kinds of yarns were tested. The research showed: polyimide fiber had a smooth surface and an irregular cross section; its macromolecular structure was stable,and its moisture regain was low; its specific resistance level was high; the fiber strength was high and toughness was good,so the spinnability of polyimide fibers was good. However,similar to ordinary synthetic fibers,the electrostatic phenomenon of polyimide fiber was serious during spinning. Therefore,in the spinning stage,the fibers should be treated with oil mist to prevent electrostatic phenomenon.
