Abstract

 
 
 The effect of bamboo portions and beating revolution on paper made from Gigantochloa scortechinii was determined. The bamboo was pulped using soda- anthraquinone (AQ) pulping comparing two pulping conditions (alkali 15 & 20%, temperature 160 & 170°C) for different bamboo portions consisted of top, middle and bottom. Hand sheets from unbeaten bamboo paper were made and the tensile index, tearing index, bursting index and folding endurance ranged from 16.35 - 32.54 Nm/g, 9.6 - 13.45 mN.m2/g, 0.81 - 1.54 kPa.m2/g and 3 - 9 double folds respectively. After that the bamboo pulp went through beating process and the tensile, tearing and bursting index and folding endurance for bamboo paper rose tremendously from 41.23 - 83.9 Nm/g, 16.64 - 27.13 mN.m2/g, 2.58 - 6.67 kPa.m2/g and 48 - 1769 double folds respectively. This revealed that bamboo paper strength can be enhanced by beating process without adding any additives.
