Abstract:
This study investigated the potential of Baccaurea ramiflora Lour. wood for alternative fiber source in pulp and paper production. Chemical compositions, basic density, fiber characteristics, kraft pulping, ECF bleaching and papermaking properties were throughout studied. The result shows that B. ramiflora wood had high lignin content and low pentosan content. The average basic density was 584 kg/m3 which could be classified in medium density wood. From the result of the optimum kraft pulping, the screened yield, kappa number, pulp viscosity and hexenuronic acid of unbleached pulp were 40.8%, 41.6, 560 ml/g and 23.1 µmol/g respectively.
Unbleached pulp had fiber length of 2.075 mm, and fiber coarseness of 0.182 mg/m which higher than the range of tropical hardwoods. Moreover, percentage of fines was very high which affected on high kappa number, high lignin and extractives content in unbleached pulp. B. ramiflora pulp could be bleached with ECF process at kappa factor 0.32 to obtain brightness of 88% ISO. Comparing with commercial bleached softwood and hardwood pulps, bleached B. ramiflora pulp had high refinability, high roughness, but low apparent density. The strength properties of bleached B. ramiflora pulp were better than those of bleached hardwood pulps, but lower than those of bleached softwood pulps. The optimum portion of softwood, B. ramiflora and hardwood in pulp blend was 20- 30%, 50% and 20-30%, respectively. The long and coarse fibers from B. ramiflora could be used as reinforcement fiber for soft tissue papers, tear-resistant papers and fiber cement board. Due to the low pentosan content, B. ramiflora wood has a potential as a raw material in dissolving pulp production.
