摘　　要：将工业脂肪酶应用于原毛洗毛,通过单因素实验探究了酶用量、温度、pH值、时间及浴比等因素对洗净毛含脂率的影响。获得合适的洗毛工艺参数为:酶用量在0.5%左右,pH值在8.0左右,浴比1:40左右,温度在60℃左右,时间2 h左右。还筛选出合适的洗毛促进剂与工业脂肪酶进行复配,以改善洗毛效果,工业脂肪酶与促进剂HM A-474B的最佳配比为1:2,对于以该比例配制的酶制剂,洗毛时的最佳用量在0.1 g/L左右。Industrial lipase was applied in raw wool scouring. The effects of many factors, such as enzyme dosage, temperature, pH, time and bath ratio, on the fat content of the scoured wool were investi-gated. The suitable parameters were obtained, including enzyme dosage 0.5%, pH 8.0, bath ratio 1:40, temperature 60?C and time about 2 h. In order to improve the scouring effect, a suitable scouring accelerator, HM A-474B, was selected and compounded with the industrial lipase. It’s observed that the best ratio of lipase to HM A-474B was 1:2, and the optimum amount of this en-zyme synergist in scouring was about 0.1 g/L.
