摘　　要：从废旧毛涤混纺面料中提取出羊毛角蛋白，配制角蛋白含量不同的3种纺丝液，通过静电纺丝方法得到羊毛角蛋白-聚乙烯醇（PVA）再生纤维。用扫描电镜观察、红外光谱分析及热学性能分析发现：3种羊毛角蛋白-PVA再生纤维膜中的纤维分布均匀、相互交叉，直径在230-260nm左右；3种再生纤维的红外光谱都具有明显的角蛋白与PVA的特征；3种再生纤维膜的热稳定性差异不大。The wool keratin is extracted from waste wool-polyester blended fabrics and three different kera- tin dopes are configured. The wool keratin-PVA regenerated fibers are produced by electro spinning. The regeneraled fibers are characterized by scanning electron microscopy, infrared spectroscopy and thermal properties analysis. The conelusinns are as follows： three wool keratin-PVA regenerated fibers are well dis- tributed, the diameters of fibers are about 230~260 nm. The infrared spectroscopies of three regenerated fi- bers have obvious characteristics of keratin and PVA. The thermal stabilities of three regenerated fibers have little difference.
