摘　　要：介绍了羊毛的结构、分子量构成及其溶解方法,还原法是目前溶解羊毛角蛋白的主要方法,只切断二硫键完整地保留角蛋白的一级结构是目前角蛋白还原水解的主要方向。探讨了还原法溶解羊毛中遇到的问题,提出了见解和主张;介绍了几种新型的羊毛溶解剂和蛋白交联的方法,鉴于目前制得的角蛋白溶液分子量较小的问题,在蛋白溶液里加入交联剂,增大角蛋白分子量是目前提高蛋白液应用性能的主要方法。In this paper,the structure,the molecular weight and dissolution method of wool were introduced.Reduction was the main method of dissolving wool,only to cut off the disulfide bonds intact keratin primary structure was the main direction of hydrolysis of keratin.Some problems were discussed appear in the reduction dissolution of the the wool and put forward some opinions and ideas.Some new dissolved agent and crosslinking methods of protein were introduced.In view of the molecular weight of keratin was small,to increase the molecular weight of keratin solution by adding cross-linking agent in the keratin solution was the main method to improve the application performance.
