摘要: 研究4种不同酪蛋白投料比的接枝改性丙烯腈纤维,从化学组成、成分含量、形态结构以及基本力学性能、摩擦性能、吸湿性能、染色性能等方面进行比较,探讨不同投料比的酪蛋白对改性丙烯腈纤维性能的影响。结果发现:酪蛋白改性丙烯腈纤维属于三元混合纤维,包括接枝上丙烯腈的酪蛋白,丙烯腈均聚物以及未反应的游离酪蛋白;随着酪蛋白含量的增加,纤维强度在一定范围内增大,吸湿、染色性能均有显著提高,但是过高含量的酪蛋白使得纤维的成型性能下降,纤维品质降低。同时对酪蛋白改性丙烯腈纤维的可加工性及开发利用提出了看法与建议。

Abstract: Four kinds of casein grafted acrylonitrile fibers with different casein feed ratioes were studied. Through analyzing and comparing the morphological structure, chemical composition, component content, the basic mechanical properties, and the frictional, hygroscopic and dyeing properties, the influence of different casein content on the performance of grafted fibers were investigated. The results showed that the grafted casein fiber is a mixture of three different things, which includes Casein-g-AN, PAN and casein. With the increase of casein content, the strength of the fiber is enhanced in some degree, and the properties of hygroscopicity and dyeing are enhanced significantly. But the formability was weakened with exorbitant casein content, lowering the fiber quality. Finally, some constructive suggestions for exploiting and making use of this kind of casein grafted acrylonitrile fibers are put forward.
