摘　　要：介绍了天然彩棉的基本特点及主要结构,阐述了天然彩棉生物酶前处理的基本原理,并利用纤维素酶和果胶酶协同作用对绿色彩棉针织物、棕色彩棉针织物进行前处理。分别探讨了纤维素酶用量、果胶酶用量、渗透剂LT-505用量对绿色彩棉针织物、棕色彩棉针织物润湿性的影响。结果表明,绿色彩棉针织物生物酶前处理最佳工艺为纤维素酶用量0.20 g/L,果胶酶用量0.10 g/L,渗透剂LT-505用量1.00 g/L,浸渍温度70℃,时间60 min,浴比1∶30;棕色彩棉针织物生物酶前处理最佳工艺为纤维素酶用量0.50 g/L,果胶酶用量0.15 g/L,渗透剂LT-505用量1.00 g/L,浸渍温度70℃,时间60 min,浴比1∶30。This paper introduces the features and main structure of natural colored cotton, expounds the basic principle of enzyme pretreatment of natural colored cotton. And the green colored cotton knitted fabric, brown cotton knitted fabric are treated by using the synergistic effect of cellulase and pectinase. It discusses respectively the effects of cellulase dosage, pectinase dosage, penetrant LT-505 dosage on wettability of green colored cotton knitted fabric, brown cotton knitted fabric. The results show that the optimal enzyme pretreatment process for green colored cotton knitted fabric is that the dosage of cellulase is 0.20 g/L, and the dosage of pectinase is 0.10 g/L, the dosage of penetrant LT-505 is 1.00 g/L, temperature is 70 ℃, time is 60 minutes, and the bath ratio is 1：30. The optimal enzyme pretreatment process for brown colored cotton knitted fabric is that the dosage of cellulase is 0.50 g/L, and the dosage of pectinase is 0.15 g/L, the dosage of penetrant LT-505 is 1.00 g/L, temperature is 70 ℃, time is 60 minutes, and the bath ratio is 1：30.
