Influence of Cellulase to Aggregation Structure of Bleached Softwood Pulp

Abstract:

Cellulase named as Celluclast 1.5L was used to deal with bleached softwood pulp. By analyzing the changes of water retention value and crystallinity of fiber after enzymatic treatment, studied the influence of cellulase to aggregation structure of bleached softwood pulp. The results show that with the increasing of the enzyme dosage, the proportion of long-fiber decreases and the content of fines increases. Water retention value of pulp first decreases and then increases. The fiber crystal does not change with the enzymatic treatment, but with the increasing of the enzyme dosage, the crystallinity of fiber first increases and then decreases. It indicates that the cellulase would act on the crystalline region of fiber in the higher enzyme dosage.
