Abstract

This study was carried out to acquire basic data necessary for the use of non-wood pulp. It investigated various chemical pulping methods using bamboo to achieve higher yield lower kappa no. and then the physical properties of various pulps were tested. The results of this study were as follows. When various chemical pulps(Soda, Soda-AQ, Soda-AQ-H2O2, Soda-urea, AS, AS-AQ, Kraft) were produced with bamboo. the pulps with the higher yield and lower kappa no. were AS-AQ and Kraft. In the case of the breaking length Soda pulps(5.77∼6.46 km) showed the greatest and Soda-urea pulps(3.81∼4.522km) showed the lower value. Similarly for the burst index Soda pulps (3.28∼3.50 kPa$.$m2/g) were the best and Soda-urea pulps(2.29∼2.39 kPa$.$m2/g) were worst. On the other hand the tearing indexes of AS-AQ pulps(73.6∼89.7mN$.$m2/g) showed the tendency which was higher then those of other pulps.
