摘要：

The kinetics of the enzymatic hydrolysis of regenerated cellulose fibers before and after acid prehydrolysis has been investigated. This pretreatment changes the kinetics from a monophasic to a biphasic first order reaction. Prolonged acid prehydrolysis increases the proportion of the enzymatically easily hydrolyzable cellulose form. The kinetics were correlated with corresponding changes of the degree of polymerization, crystallinity and crystallite size. Copyright © 1990 John Wiley & Sons, Inc.
