淀粉酶是水解淀粉和糖原的酶类总称，通常通过淀粉酶催化水解织物上的淀粉浆料，由于淀粉酶的高效性及专一性，酶退浆的退浆率高，退浆快，污染少，产品比酸法、减法更柔软，且不损伤纤维。淀粉酶的种类很多，根据织物不同，设备组合不同，工艺流程也不同，目前所用的退浆方法有浸渍法、堆置法、卷染法、连续洗等，由于淀粉酶退浆机械作用小，水的用量少，可以在低温条件下达到退浆效果，具有鲜明的环保特色。

Amylase hydrolysis of starch and glycogen is the general term for enzymes, usually through the hydrolysis enzymatic starch on the fabric of the starch slurry, as a result of the high-amylase and specificity, the enzyme desizing desizing the high rate of speed desizing, Less pollution, acid products than the law, subtraction more flexible and does not damage fibers. Amylase, many different types, according to the different fabrics, the mix of different equipment, different processes currently used by the impregnation method desizing, Duizhi law, Jigger law, such as washing in a row, as amylase desizing the role of small machinery, Use less water, low temperatures can reach desizing effect, with distinct environmental characteristics.
Key words: amylase hydrolyzed starch desizing glycogen environmental protection
