复合纤维素酶水解对漂白马尾松纤维形态和结构的影响
Influence of complex cellulase hydrolysis on fiber morphology and structure of bleached masson pine
摘要
Abstract
The effect of complex cellulase on the bleaching masson pine fiber surface ,mor‐phology parameter and structure was investigated .The results showed that increasing the time and dosage can enhance the degree of hydrolysis reaction within a certain range .The cel‐lulase preferentially acted on fines existed in the sample and on the surface of the fiber .With the increasing of dosage ,peeling and breaking occured ,fines content increased ,the average length increased at first and then gradually reduced .The degree of polymerization of the cel‐lulase and reaction efficiency was gradually decreased .When the dosage was 20 U · g‐1 ,the average length decreased by 70% ,fines content increased from 16 .8% to 72 .4% ,the degree of polymerization decreased by 53% .The crystallinity had a periodical change which in‐creased first and then decreased .Within a certain time ,the crystallinity showed that cellulase hydrolysed the amorphous at first ,then cellulase acted on the amorphous and crystallization zone at the same time ,but the crystal structure remained the typical cellulose I .关键词
