摘要/Abstract

摘要： 本文利用机械-生物酶联合脱胶工艺对棉秆皮进行脱胶。应用模糊数学方法处理机械-生物酶联合脱胶的正交实验评价指标值，解决了两个评价指标优化条件不一致的问题，得出机械-生物酶联合脱胶优化工艺参数为酶浓度6%，pH值4.4，温度60℃，时间8h,棉秆皮纤维的残胶率为8.09%,木质素残余率为9.64%。采用FTIR、SEM和XRD进行测试，讨论了棉秆皮纤维的化学结构、微观表面形态及纤维素结构的变化,为棉秆皮纤维的染色与产品开发提供理论指导。

Abstract: In order to avoid the serious environmental pollution from chemical degumming, the combined mechanical and enzyme degumming of cotton bast fiber was suggested. During the combined mechanical and enzyme degumming, the results of orthogonal design was optimized by fuzzy mathematical theory, solved the question when optimization conditions of two evaluation targets were variance, indicated the optimization condition enzyme density 6%, pH 4.4, temperature 60℃, time8 hour, glue remnant rate was 8.09% , lignin remnant rate was 9.64%. The structure and morphology of degummed fiber were discussed by FTIR、SEM and XRD analysis, for the dyeing and production of cotton bast fibers.

Key words: cotton stalk bast, mechanical-enzyme degumming, fuzzy math orthogonal test, fiber structure
