摘　　要：结合生物酶和化学方法对亚麻纤维进行脱胶处理,运用正交试验法研究酶脱胶和化学脱胶对亚麻纤维脱胶效果的影响,得出基于酶脱胶和化学脱胶亚麻纤维的优化工艺参数为:预处理阶段脱胶温度50℃,果胶酶浓度为1 g/L,H_(2)SO_(4)浓度为3 g/L,预处理时间为60 min;化学处理阶段脱胶温度为50℃,脱胶时间为70 min,H_(2)O_(2)浓度为6.0%,NaOH浓度为8.0%.与传统化学脱胶相比,生物酶化学联合脱胶后纤维的断裂强力基本保持不变,白度、脱胶率均优于前者.This study combines biological enzymes and chemical methods to degum flax fibers,and uses orthogonal tests to investigate the effects of enzymatic and chemical degumming on the degumming efficiency of flax fibers.The optimized process parameters for enzymatic and chemical degumming of flax fibers are determined as follows:during the pretreatment stage,a temperature of 50℃,pectinase concentration of 1 g/L,H_(2)SO_(4) concentration of 3 g/L,and a pretreatment time of 60 min;during the chemical treatment stage,a degumming temperature of 50℃,degumming time of 70 min,H_(2)O_(2) concentration of 6.0%,and NaOH concentration of 8.0%.Compared with traditional chemical degumming,the combined bio-enzyme chemical degumming maintains the tensile strength of the fibers,while improving the whiteness and degumming rate.
