Abstract: 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.
