摘　　要：采用酸性纤维素酶对棉织物进行抛光处理，探讨pH值、温度、时间、水洗机转速、浴比和酶用量等处理条件对抛光效果的影响。结果表明，在pH值为4．5～5．5、温度50～60℃时，酸性纤维素酶的作用效果较好；处理时间越长、水洗机转速越快、浴比越小，酸性纤维素酶的作用越强；随着酶加量的增加，酸性纤维素酶的作用效果逐渐上升，在用量达10％后，趋于饱和。Factors exerting influence on cotton bio-polishing with acidic cellulase are discussed, such as pH value, temperature, time, rotation speed of the machine, bath ratio and cellulase concentration. The results show that the acidic cellulase has excellent effect under the condition of pH value of 4.5 -5.5 and temperature of 50 - 60 ℃. The acidic cellulase keep good activity under long treatment time, fast speed of the machine, low bath ratio and high enzyme concentration, and it has the maximum activity with concentration of 10%.
