摘　　要：通过预处理、复合酶处理和碱精炼工艺对苎麻纤维进行脱胶处理,得到优化的碱性复合生物酶脱胶工艺:将乙二胺四乙酸二钠水溶液预处理的苎麻纤维通过果胶酶(40g/L)和漆酶(10g/L)的复合酶在52℃处理3h;随后,在100℃通过NaOH水溶液(10g/L)继续处理3h。通过该工艺处理后的苎麻纤维残胶率为4.8%,断裂强力为5.06cN/dtex,白度为50.1度,其各项技术指标基本达到三级苎麻精干麻的要求。The effect of pre-treatment,compound enzyme treatment and alkali refining on the ramine fibers degumming was stud-ied.The optimized alkaline compound bio-enzyme degumming process of ramie fibers was obtained.Ramie fiber was pretreated with ethylenediaminetetraacetic acid disodium solution and treated with pectinase(40 g/L)and laccase(10 g/L)compound enzymes at 52℃ for 3 h,and then treated with NaOH solution(10 g/L)at 100℃for3 h.The residual glue rate of ramie fiber after treatment was 4.8%,the fracture strength was 5.06 cN/dtex,the whiteness was 50.1%,and its technical index basically met the requirements of the third grade.
