The effect of Several Pulp properties and freeness treated with different sized cellulase
섬유소 분해효소의 분자량에 따른 조합처리가 종이의 강도 변화 및 표면 변화에 미치는 영향
Abstract
This study confirmed different results according to the molecular weight and pore properties of treated pulp. In this study the pre-treated enzyme material was increasing the beating speed compared with non-treated one. And it was observed that the change of freeness according to the combination ratio depended upon the pores size of pulp and that fibers became flexible owing to the physical deformation of fibers themselves through pre-treated enzyme increasing the flexibility of fibers to increase the contact area of fiber and thus resulting in the increase of specific surface area, the increase of fiber bonding strength and the increase of beating speed.
