| Abstract:Using pinus massoniana kraft pulp as raw material,the effects of fluff pulp preparation technology including alkali (NaOH) dosage, hydrogen peroxide(H2O2) dosage, temperature and concentrated alkaline treatment time on the fluff pulp properties were investigated. It showed that the optimal technology was as the follows: NaOH dosage 8%, H2O2 dosage 1.8%, temperature 70℃, concentrated alkaline treatment time 10 min. The brightness of the pulp was 76.1% ISO and increased 51.6% compared with the original kraft pulp, burst index was 0.57 kPa·m2/g and decreased 48.2%, density and the absorption time decreased 11.8%, 47.5%, respectively. Meanwhile, absorption and dry bulkiness of the pulp decreased 8.32%, 5.43%, respectively. The brightness of the pulp reached 82.4% ISO when it was further bleached with H2O2, while other properties of the pulp met to the requirement of the national standard GB/T 21331—2008. |
