Influences of Bleached Softwood Pulp Pretreated with Endo-Cellulase on Fiber Surface Properties and Aggregation Structure

Abstract:

The influences of endo-cellulase pretreatment of bleached softwood pulp before refining was investigated in this paper. Refining energy consumption, paper properties, wetting properties, electric charge and aggregation structure of fiber were investigated. The results showed that pretreated with endo-cellulase at the dosage of 0.4ECG/g before refining could increase the refining degree by 53.09%, and it would reduce refining energy consumption significantly. At this dosage, the tensile index of the paper sheet increased while the tear index of paper sheet decreased slightly. Additionally, enzymatic pretreatment could raise fiber surface wettability, lower the absolute value of Zeta potential and decrease the crystallinity of fiber, which was help to improve refining performance.
