5、,从而为酰氯化提供条件。通过羧基与氯化亚砜之间的酰氯化反应,赋予纤维以酰氯强极性基团(COCl),这是实现聚丙烯腈纤维与蛋白质接枝的基础。接枝是通过酰氯基团与蛋白质中的氨基(NH2 )和羟基(OH)发生不可逆氮酰化和酯化反应实现的。首次用大豆分离蛋白和豆浆实现了聚丙烯腈纤维的蛋白质表面接枝改性,揭示了各工艺条件对接枝率的影响规律,分析了接枝纤维的结构和形态,并对其回潮率、吸水率、抗静电性、力学性质、热稳定性等性能等进行了研究。以豆粕为原料,通过碱提酸沉法制备大豆分离蛋白的最佳浸提工艺条件为:浸. 更多【关键词】 聚丙烯腈纤维； 大豆分离蛋白； 豆浆； 水解； 酰氯化； 接枝； 五、国家科技图书

12、rylonitrile (PAN) fibers were prepared using the blends of PAN and various molecular weight of polyethylene glycol (PEG) by wet-spinning process and water bath post-treatment. The chemical structure and morphologies of the modified PAN fibers were studied. The water transportation, water retention,

13、moisture absorption and mechanical properties of the fibers were discussed. Results show that there is no residual PEG in modified PAN fibers after drawing process in hot water bath and post-treatment. With the increase in PEG molecular weight, the fiber surface grooves become deeper, the inner pore

14、 size increases, while the mechanical properties decrease. The water absorbing and transferring capabilities of the modified PAN fibers can be improved in varying degrees due to the different pore structures left by series molecular weight of PEG removing. 2010 The Korean Fiber Society and Springer
