摘　　要：为了克服兔毛纤维表面光滑、摩擦系数小而导致纤维之间抱合力小,可纺性差的缺点,用双氧水对兔毛预处理后,再使用蛋白酶进行处理,使纤维之间获得一定的抱合力。通过分析不同质量分数的蛋白酶对纤维断裂强力、摩擦系数及表面形态的影响,发现当蛋白酶质量分数占所处理纤维质量的5%时,纤维表面的形态结构发生明显改变,表面摩擦系数显著提高,从而增加了纤维之间的抱合力,能提高兔毛纤维的可纺性。Angora rabbit fiber is of smooth fiber surface and low friction coefficient,which are disadvantages for spinning.Angora hair is pretreated with H2O2,and then treated by enzymatic to solve these problems.The effect of enzymatic content on the fiber strength and the coefficient of surface friction are analyzed.An optimum process,with the enzymatic content of 5% to the fiber being treated,liquor ratio（fiber/water） of 1/25,temperature of 45℃ and time of 15min is determined,which results in changed morphological structure for the fiber surface.Thus,the friction coefficients and inter-fiber cohesions of the fibers are enhanced.
