摘　　要：羊毛角蛋白含有芳香族氨基酸,对紫外光吸收性良好。采用氢氧化钠和双氧水溶解羊毛制备角蛋白溶液,优化的制备工艺为:羊毛1 g,NaOH 1 g,30%双氧水0.5 mL,溶解温度45℃,溶解时间3 h,浴比1∶50。红外光谱分析显示,羊毛提取物是以α-螺旋型构象为主的蛋白质。经角蛋白溶液整理后的氧化棉织物的UPF值达25.78,对紫外光的UVA段和UVB段均有良好的屏蔽效果,且耐洗牢度良好。Keratin solution is prepared by dissolving wool fiber with sodium hydroxide and hydrogen peroxide. The optimum extraction process is determined as follows： wool fiber 1 g, NaOH 1 g, 30% H202 0.5 mL, dissolving at 45 ℃ for 3 h with bath ratio 1 ： 50. Infrared spectrum shows that the wool extract is a kind of protein mainly containing α-helical conformation. Selective oxidized cotton fabric treated with wool keratin solution features improved UPF value of 25.78 and excellent shielding effi- ciency for UVA and UVB, as well as good washing fastness.
