The author studied that the effect on the fine structure of bumboo pulp by the conditions of cooking and bleaching methods, and main results was obtained as follows.(1) Crystalline content of 24-mesh pulp that removed short fiber by screening was higher value than that of pulp before screening.(2) Sodium chlorite bleaching pulp was higher viscosity than hypochlorite bleaching one, but there was a few difference between viscosity of their crystallized region. This showed that pulp was more attacked in hypochlorite solution than in sodium chlorite solution, but attack on pulp was only non-crystallized region of pulp.(3) When consumed much active alkali at cooking, viscosity of crystallized region of pulp decreased. It stowed that effect of crystallized region due to the cooking condition.(4) Crystalline content of pulp that consumed much active alkali was high value, but viscosity of their crystallized region was low value. This was assumed that structure of their crystallized region consists of short crystalline.
