| Abstract: | The catalytic action of acid cellulase and the principle of cashmere washing were studied in this paper.The concentration of acid cellulose 325,the washing temperature,time and pH value on effect of wool wash were discussed to achieve the optimum conditions and process of acid cellulose 325.By analyzing the reducing rate of single fiber breaking strength and weight loss rate of cashmere after washing,the efficient and environmentally friendly conditions of enzyme washing were optimized,which was as follows:pH 5,concentration of acid cellulose 1%(owf),washing time 30 min and washing temperature 50℃;The optimum result was weight loss rate more than 19%,and the reduction rate of single fiber breaking strength below 15%. |
