摘　　要：针对蛋白酶在羊毛防缩整理中对纤维内部损伤较大、水解鳞片效率低、均一性差的问题,采用聚多巴胺交联蛋白酶在pH值为8,温度为40℃的条件下对羊毛进行处理。分析了多巴胺底物质量浓度和处理时间对羊毛纤维物理、力学和润湿性能的影响。结果表明:与蛋白酶处理的羊毛纤维相比,经聚多巴胺-蛋白酶联合处理的羊毛纤维防缩性能、润湿性能和纤维细度均有所提高;多巴胺底物浓度和反应时间会对羊毛纤维力学性能造成相反影响。In response to the problems of significant damage to the fiber interior,low hydrolysis efficiency,and poor uniformity caused by protease in wool anti shrink finishing,polydopamine cross-linked protease is used to treat wool at pH of 8 and temperature of 40 C.The effects of dopamine substrate concentration and treatment time on the physical,mechanical,and wetting properties of wool fibers are analyzed.The results show that compared with the wool fibers treated with protease,the wool fibers treated with the combination of dopamine protease show an improvement in anti-felting,wetting,and fineness in comparison with scoured wool fiber.Dopamine substrate concentration and reaction time have opposite effects on the mechanical properties of wool fibers.
