摘要
利用聚丙烯腈纤维和胶原蛋白为基本原料,采用水解-焙烘法制备具有高吸湿性和耐久性良好的胶原蛋白改性聚丙烯腈纤维。借助FT-IR、TG、XRD、DMA、SEM等分析和讨论了改性纤维的结构和性能。结果表明,与改性前相比,改性纤维的表面光滑,表层附有大量胶原蛋白成分,回潮率由2.0%提高到了6.1%,热分解温度由318℃下降到296℃,力学性能有所下降,改性纤维耐久性较好。
With polyacrylonitrile fiber and collagen as the basic raw material, collagen modified polyacrylonitrile fibers with a high moisture regain and durability were prepared by hydrolysis-baking method. The structures and properties of collagen modified polyacrylonitrile fiber were analyzed by means of FT-IR, TG, XRD,DMA, SEM techniques. Results show that. compared with unmodified fiber, the surface of modified fiber is smooth and covered by a large number of collagen composition, the moisture regain increased from 2% to 6. 1% ,thermal decomposition temperature decreased from 318℃ to 296℃. The breaking strength and elongation of collagen modified polyacrylonitrile fiber are decreased too.
