| Abstract: | Eulaliopsis binata was cooked by soda and soda–AQ pulping processes and
results were compared with alkali-O2, alkali-O2-AQ and
NSSC pulping processes. Even the nodes are not resistant to the action of
cooking liquor and consequently at 14 % alkali dose whole plant is reduced to a
clean and regular pulp giving 48 % screened pulp yield of Kappa number 16. A
screened pulp yield of 49.8 % at Kappa no 15.7 was obtained at 12 % alkali and
0.5 % AQ. In order to get 80 % (ISO)
brightness, the pulp was bleached by single stage hypochlorite bleaching, O2
delignification followed hypochlorite bleaching, peroxide bleaching, O2
delignification followed by peroxide, CEH and OCEH bleaching sequences. Various
paper grades like news print, light weight writing
and printing paper, cigarette tissue, condenser paper, high grade bond, ledger
and other cultural papers can be manufactured by selecting an appropriate pulp
brightness and blending with long fibred pulp |
