摘要
以正十九烷和正二十烷以及正十八烷微胶囊为原料,采用熔融复合和溶液纺丝工艺制备相变材料(微胶囊)质量分数2000以上的蓄热调温纤维,观察其可纺性,测试纤维的结构并研究纺丝工艺对其相变性能、热效率、物理力学性能和耐热性能的影响.结果表明,采用相变材料微胶囊和聚丙烯腈偏氯乙烯共聚物混合后进行溶液纺丝制成的腈氯纶纤维具有较好的可纺性,热效率和热稳定性最高,但物理力学性能较差.
By using n-nonadecane and n-eicosane and microencapsulated n-octadecane respectively as phase change materials, the thermo-regulated fibers in which the content of phase change materials is more than 20~0_0 have been prepared with melt spinning and wet spinning process, and the spinnability is observed.The structure of this fibers is tested and the effects of process on phase change properties, heat efficiency, physical mechanical properties and thermal stability of the fibers are studied. The results show that, the wet-spun fibers using microencapsulated n-octadecane and polyacrylonitrile-vinylidene chloride as raw materials have good spinnability and the highest heat efficiency and thermal stability among three kinds of fibers, but the physical mechanical properties of this kind of fibers are not good enough.
