兔毛纤维的酶处理

为了克服兔毛纤维表面光滑、摩擦因数小及其产品容易脱毛的缺点,对兔毛纤维用双氧水(30%)处理后,再配合酶处理工艺,使纤维得到一定的减量率。通过分析蛋白酶含量、酶处理时间对兔毛纤维直径、强度、伸长率、表面摩擦因数的影响,确定合适的酶处理工艺,使兔毛纤维的强度和伸长率变化在尽可能小的情况下,纤维表面形态结构发生改变,从而提高了其表面摩擦因数,增加了纤维之间的抱合力,提高了纤维的可纺性,大大减少了兔毛纺织品的脱毛现象。

Enzymatic treatment of rabbit hair fiber

Rabbit hair fiber is characterized by smooth fiber surface,low coefficient of friction,and the tendency to depilating.To overcome these phenomena,the rabbit hair was first treated with hydrogen peroxide solution(30%),followed by enzymatic treatment so that weigh deduction of the fiber was achieved to a certain extent.The effect of protease content and enzymatic treating time on the fiber diameter,strength,elongation,and the coefficient of surface friction was analyzed,and a suitable process of enzymatic treatment was determined,which changed the morphological structure of the fiber surface with the least possible variation in strength and elongation.Thus,the fiber surface friction coefficient,inter-fiber cohesion,and spinnability were enhanced,and the depilation of the rabbit hair textile product was also greatly improved.
