摘　　要：针对麻纤维采用化学脱胶会对纤维造成损伤的问题,提出了大麻纤维果胶酶脱胶的新方法。用正交试验方法确定了果胶酶脱胶的最佳工艺,即作用时间2 h,果胶酶浓度5 g/L,pH值4.5,温度50℃;后处理氢氧化钠浓度0.6%。Aimed at the problem of the hemp fiber damage due to chemical degumming, a new method that the hemp degumming with pectinase enzyme. Moreover,diagonal intersection trial method was used to determine the optimum processing, i. e. the processing time period was 2 h, concentration of pectinase enzymes-5g/L, pH value-4. 5, temperature-50℃, concentration of NaOH in post-treatment-0.6%. Using hemp degumming with pectinase enzyme, the processing condition was temperate, thefibre damage was little, and level of degumming was easy to control in production, being favorable to improve the output of degummed hemp, decrease the water consumption and environment pollution.
