Biomanufacture of Cotton Fiber by Chemically modified Cellulases

采用纤维素酶对棉等纤维素类原料进行减重处理，以提高织物质量。然而，纤维素酶对织物进行整理往往会导致强力下降。为了避免这种现象，我们用聚合物对纤维素酶进行了化学修饰。结果表明，纤维素酶的相对分子质量增加。改性纤维素酶(高摩尔质量纤维素酶)对纤维强度的降低有一定的保护作用。纤维的酶处理不影响染色效果。

For improvement of quality of cloth from cellulsic substances such as cotton, cellulases were applied to weight reducing tretment. However, tretment of cloth by cellulase often caused decrease of strengh. To avoid this phenomenon, we modified cellulases chemically with polymers. As the results, molecular weight of cellulase increased. The decrease of strength of fiber was relatively protected, when modified cellulase (high mol wt.cellulase) was used. Enzyme treatment on fiber did not affect color staining.
