摘　　要：对棉织物的酶高温轧蒸工艺进行研究，讨论了酶浓度、轧余率、轧酶温度、酶液pH值和汽蒸时间等因素对退浆效果的影响，初步确定淀粉酶退浆工艺为：淀粉酶L401．5-2g／L，轧余率100％～110％，室温轧酶（轧前先浸轧60℃热水），酶液pH值约6．5，汽蒸时间15min，汽蒸温度100—102℃。比较碱轧蒸退浆工艺发现，酶退浆工艺退浆率较高，可达7级以上，但毛效、润湿性和白度稍低。Desizing at high temperature by means of padding and steaming process on cotton fabric with amylase was researched,and the factors,such as amylase concentration,pick up, pH value, temperature of padding solution, time of steaming to amylase desizing were discussed. The optimal desizing process was determined, that is amylase L40 1.5 - 2 g/L, pickup 100% - 110%, padding hot water at 60℃ prior to padding amylase at room temperature, pH value 6.5, steaming at 100 -102℃ for 15 min. The desizing effects was compared with that of alkali desizing by means of padding and steaming process.
