On the change of crystallized region during the sulfate pulping process

Abstract

The author studied the change of fine structure of beech pulp during sulfate cooking process, and following results were obtained:
1) Mild cooking condition gave less active effect than that of drastic procedure.
2) With progressive cooking, crystalline region and viscosity gradually decreased, but Ke increased. These effects were assumed to be originated from the reduction of both length and width in crystalline particle.
