摘　　要：研究了羊绒炭化过程中木质素酶的催化作用以及机理。以羊绒的单纤维断裂强力、白度及失重率为指标,探讨了木质素酶用量、温度、时间以及pH的影响,得到了木质素酶洗绒炭化的优化工艺:木质素酶用量1.5%(omf),温度45℃,时间35 min,pH 5.5。相比传统酸炭化工艺,木质素酶洗绒炭化优化工艺的单纤维断裂强力和白度分别提高68.94%、68.8%,失重率下降26.8%。The catalysis and mechanism of ligninase in cashmere carbonization were studied.Taking single fiber breaking strength,whiteness and weight loss rate of cashmere as indexes,the effects of ligninase dosage,temperature,time and pH were discussed,and the optimal process of enzyme washing was as follows:ligninase dosage 1.5%(omf),temperature 45℃,time 35 min,pH 5.5.Compared with the traditional acid carbonization process,single fiber breaking strength and whiteness of the optimal cashmere washing carbonization process increased by 68.94%and 68.8%,respectively,and the weight loss rate decreased by 26.8%.
