Unbleached pulp and paper properties of soda-anthraquinone pulping of paraserianthes falcataria / Muslyza Che Hussin

This study was conducted to investigate the potential of Batai (Paraserianthes falcataria ) as a raw material for the pulp and paper industry. Three batai trees with a DBH of an average DBH of 26.7cm and an average tree height of 10.55 m were harvested from Donghwa Plantation in Merbok, Sg. Petani,...

The study also investigate the effects of the tree portion (bottom and top), percentage NaOH (16%,18% and 20%) used, percentage of AQ (control & 0.1%) and beating revolutions (0, 5000, 10000, 15000, 20000 and 25000 rev) on the unbleached pulp and paper properties.

The addition of 0.1% AQ in soda pulping increase the pulp yield, pulp screened yield and lower pulp screened reject.

The presence of AQ results in low physical properties of paper namely; thickness and paper grammage. The folding endurance, burst index, tensile index and tear index are higher with 0.1% of AQ. The presence of AQ improved the brightness and lower the opacity of paper. The increase in beating revolution on the unbleached pulp results in lower CSF of pulp and thickness of paper. The better mechanical properties of paper (number of fold, tensile index, burst index and tear index) is a results of higher beating revolutions.
