摘　　要：羊毛角蛋白具有良好的生物相容性及可降解性,且含有大量的氨基、羧基等亲水基团,是一种无毒、亲肤的可再生绿色物质。毛纺行业每年产生约10万t羊毛纤维废料,因为短羊毛纤维不适合纺纱而被填埋处理,造成环境污染。如何将废旧羊毛纤维加以利用是目前急需解决的问题。主要表征了羊毛角蛋白的结构,并探索了其在压力传感器领域的应用,通过还原法提取废旧羊毛纤维中的羊毛角蛋白,对于废旧羊毛纤维的再利用具有重要意义。Wool keratin has good biocompatibility and degradability,and contains a large number of amino,carboxyl and other hydrophilic groups,which is a non-toxic,skin-friendly renewable green substance.100 000 t of wool waste fibers is produced from wool spinning industry every year and landfill treatment is used because short wool fibers are not suitable for spinning which caused environmental pollution.How to use waste wool fibers is an urgent problem to be solved.The structure of wool keratin was characterized and its application in the field of pressure sensor was explored.The reduction method for extracting wool keratin from waste wool fibers is of great significance for the reuse of waste wool fibers.
