摘　　要：根据化学自组装原理,在Schotten—Baumana缩合法路线基础上,利用从废革屑中提取的胶原蛋白对聚丙烯腈(PAN)纤维进行表面改性。试验表明:经优化试验处理,得到的改性纤维胶原蛋白含量为8.45%,吸水率为18.2%,比PAN纤维提高了93.6%,酸性红B平衡上染百分率为91%,高于PAN纤维的14%。Poiyacrylonitrile（PAN） fiber was surface modified by collagen extracted from leather waste, based on the principle of chemical self - assembly and on the basis of Schotten - Baumana condensation route. The results indicate that after the treat- ment of optimal experiment, the modified fiber is obtained With 8.45% collage content, and the water absorption is 18.2% which has a 93.6% increase over PAN fibers. Moreover, the balance dye uptake of acid Red B on modified fiber was 91% , which is 14% higher than that of PAN fibers.
