Effect of Cellulase Pretreatment on Beatability of Pulp and Physical Properties of Paper

셀룰라아제의 전처리가 펄프의 고해도 및 종이의 물리적 성질에 미치는 영향

Abstract

Several enzyme were applied to Laubholz Bleached Kraft Pulp(LBKP) to evaluate the influence on beatability which was measured in Schopper Riegler value, and the results were compared with untreated pulp. Among the types of enzyme, cellulase was found to be the most effective. Addition of cellulase increased the beatability by 28% at optimum condition. Strength properties such as tensile strength and folding endurance also increased with enzymatic treatment by 12% and 46%, respectively. However, excessive dosage of cellulase had an adverse effect on strength properties in spite of the high beatability. Fibrillization by cellulase and destruction of fiber by excessive reaction was observed by Scanning Electron Microscopy(SEM).
