Biomanufacture of Cotton Fiber by Chemically modified Cellulases

为了提高棉等纤维素原料的织物质量，采用纤维素酶进行减量处理。但纤维素酶对织物的处理常引起强力下降。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，纤维素酶的分子量增加。使用改性纤维素酶（高分子量纤维素酶）时，纤维强度的下降得到了相对保护。纤维酶处理不影响染色。

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.
