摘要
研究了纤维素酶对棉纤维结构和织物相关性能的影响。结果表明:纤维素酶在使棉纤维表面发生部分剥蚀的同时,也侵蚀到纤维的空穴和毛细管中,其作用不仅发生在无定形区,而且“蚕食”晶区使纤维的结晶度有所下降;并可能将部分晶区转变为无定形区;纤维的聚合度随减量率的增加而下降;酶处理织物的柔软性提高;减量率应掌握在4%左右,使强力损失控制在10%以内,否则将影响织物的服用性能。
The influences of cellulase on structure and related property of the cotton fabric were studied. The micmgraphs showed that there were corroded phenomena not only on the surface but also into gap and capillary of cotton fiber. The crystallinity of cotton was decreased and partial crystalline could be transfered into amorphous. The polymerization degree of cotton fiber was decreased with the increasing of lost weight rote. Although the fabric qualities such as softness and surface smoothness were improved, the lost weight rote should be controlled about 4% , and the loss of strengh should be also controlled within 10% . The property of fabric would be damaged if the process was not controlled properly.
