Abstract

Enzymatic treatments have different effects on different types of pulps. In this study, the effect of cellulase treatment on drainage and dewatering capability and also paper Strength Properties of four types of first-hand (virgin) and recycled pulp was investigated. First-hand pulp included chemimechanical pulp (CMP) made from hardwoods (mixture of beech, hornbeam and poplar) of Iran northern forest and imported softwood Bleached Kraft pulp (BKP) while recycled pulp comprised of Old corrugated containerboard (OCC) pulp and Deinked pulp (DIP). Both types of recycled pulps have been sourced from domestic factories in Iran. For enzyme treatment of pulp, the consistency of the pulp was set at 10%, the Cellulase Enzyme intake was 0. 5% based on the dry weight of the pulp, the temperature, time and pH of the reaction were set at 50 Celsius centigrade, 60 min, and 5. 5 to 6. 5, respectively. From all kind of the pulp, before enzymatic treatment, fiber classification was performed in Bauer McNett fiber classifier and dimensional distribution of fibers and fine content in different types of pulp was determined. The results of this study showed that the effect of Cellulase Enzyme on chemical pulps with less lignin is more than semi-chemical pulp with more lignin and low cellulose. Cellulase enzymatic treatment increases the Strength Properties of pulp with more cellulose and improves the drain ability of the pulps with more fine content such as CMP and OCC.
