摘　　要：研究羊毛角蛋白对氧化竹原纤维改性的工艺。采用高碘酸钠对竹原纤维进行选择性氧化,再利用羊毛角蛋白溶液对制得的氧化竹原纤维进行改性整理,测试并分析了羊毛角蛋白处理时间、处理浓度、处理温度、pH值对氧化竹原纤维增重率和强伸性能的影响。整理结果表明,角蛋白溶液处理氧化竹原纤维后在纤维表面吸附成膜并产生增重,同时处理后氧化竹原纤维的强伸性能也有所提高。较理想改性工艺为:羊毛角蛋白溶液质量百分比浓度3%,处理温度40℃,溶液pH值6,处理时间1 h。Processing of oxidized natural bamboo fiber modification with wool keratin was studied. NalO4 was selected to oxidize natural bamboo fiber selectively then the oxidized natural bamboo fiber was treated by wool keratin solution. Effect of wool keratin treatment time, concentration, temperature, pH value on natural bamboo fiber weighting percentage and strength ＆ elongation was tested and analyzed. The result shows that the surface of oxidized fiber treated by keratin solution forms a film and their weight rises. The strength ＆ elongation properties of oxidized natural bamboo fiber increased in a degree. Better modification processing is quality percentage concentration 3% , treatment temperature 40℃ ,solution pH value 6 and treatment time 1 h.
