摘　　要：采用纸浆酶、纤维素酶和碱性果胶酶对棉织物进行氧煮漂一浴工艺处理,考察pH值、温度和双氧水对酶活稳定性的影响。研究表明,纸浆酶、纤维素酶和碱性果胶酶的最适反应pH值分别为8,5和11;三种酶最适反应温度为60-70℃,且对双氧水具有一定的耐受性。因此,酶氧煮漂一浴工艺的可行性,关键在于寻找耐高温、耐双氧水和最适pH值的高稳定性碱性酶。The enzyme-peroxide one-bath scouring and bleaching process of cotton fabric was carried out with pulpzyme,cellulase and pectinase individually.The results showed that the optimum pH value of pulpzyme,cellulase and pectinase was 8,5 and 11 respectively.The three enzymes had the highest activity at the temperature of 60~70 ℃,and were stable at a certain amount of hydrogen peroxide.Therefore,enzyme-peroxide one-bath scouring and bleaching process was feasible,the key was to find out the enzymes which could stand high temperature and appropriate pH value.
