Abstract

Effects of low concentration alkali-cosolvent swelling pre-treatment on beating characteristics of softwood bleached kraft pulp (SwBKP) fibers was investigated. Urea was applied as a cosolvent. When the pulp was swollen at a low concentration below 2% (based on the oven-dried pulp), the weight loss was below 1%. NaOH treatment below 2% concentration could improve the swelling of SwBKP. Addition of urea with NaOH solution promoted the swelling. In addition, low concentration NaOH-urea pre-treatment reduced the beating time to reach a certain level of beating degree. Lowest freeness level was obtained when SwBKP was treated with 1% NaOH while highest fibrillation level was obtained at 2% NaOH and 1% urea. It could be concluded that grinding efficiency could be improved by the low concentration alkali-cosolvent swelling while optimization for the pre-treatment is necessary.
