摘　　要：针对罗布麻韧皮纤维成分的特性进行脱胶,并以温度、时间、pH值、浴比为控制条件,进行了单因子试验和正交试验,结果表明四因素的优先等级为温度>时间>pH>浴比,时间因素影响较大,通过残胶率和失重率两项指标的综合评价,得出了罗布麻的最优脱胶控制参数为:脱胶时间48 h,浴比1/30,pH=8,θ=34℃。同时对脱胶后的纤维进行了检测:纤维强度5.48 cN/dtex;断裂伸长率4.25%;纤维支数2339支;回潮率10.2%。为罗布麻韧皮纤维采用酶法脱胶提供了依据。The degummed experiment of the apocynum was preformed and the orthogonal result indicated that the priority order is temperature〉time〉pH〉bath ratio and the key factor is degummed time. The optimum degumming conditions were： processing time 48 hours, bath ratio 1 ： 30, pH 8. 0 and temperature 34 ℃. The degummed fibers were detected, in which fiber strength was 5.48 cn/dtex, elongation at break was 4.25%, fiber count was 2339, moisture regain was 10.2%.
