中性纤维素酶FE洗绒工艺的应用

研究了羊绒洗涤过程中中性纤维素酶FE的催化作用及性能,通过探讨中性纤维素酶FE用量、温度、时间以及pH 4个因素来优选工艺条件,通过分析处理后羊绒的单纤维断裂强力、白度及失重率优化出高效、环保的酶洗条件:中性纤维素酶FE用量1.5%～2.5%(omf),pH=5.5～6.5,洗绒温度45～55℃,洗绒时间35～45 min;与传统的酸炭化工艺相比,中性纤维素酶FE洗绒工艺处理后单纤维的断裂强力和白度分别提高70.3%和72.4%,失重率下降61.4%。

Application of neutral cellulase FE cashmere washing technology

The catalytic action and performance of neutral cellulase FE in the washing of cashmere were studied. The optimum technological conditions were optimized by discussing the four factors of neutral cellu-lase FE dosage, temperature, time and p H. By analyzing the breaking strength, whiteness and weight loss rate of treated cashmere fibers, the optimum conditions of highly efficient and environmental protected enzymatic washing process were as follows: neutral cellulase FE dosage 1.5%~2.5%(omf), p H=5.5~6.5, washing temper?ature 45~55 ℃, washing time 35~45 min. Compared with traditional acid carbonization, the breaking strength and whiteness of fibers treated by neutral cellulase FE cashmere washing were increased by 70.3% and72.4%, respectively, and the weight loss rate decreased by 61.4%.
