Abstract

KOCC is used as a very important raw material in industrial paper manufacturing in Korea. However, as KOCC is repeatedly used as a raw material, the aging and hornification of the pulp becomes more severe, making it difficult to produce industrial paper of excellent strength. In order to solve these problems, various methods such as addition of virgin pulp, enzyme treatment, mechanical treatment and polymer additive have been applied. This study was carried out to evaluate the applicability of swelling treatment by soaking after beating in order to improve the quality of KOCC by environmentally friendly method. As a result of this study, the WRV of KOCC and UKP increased with increasing soaking time, while the freeness tended to decrease. The air permeability of KOCC handsheet showed a tendency to decrease by swelling due to soaking, but the opacity and bulk did not show any significant changes. The tensile index was slightly improved by soaking, but no significant changes were observed in the tear index and Taber stiffness. Considering the above results, although swelling due to soaking helps somewhat to improve some physical properties, it is difficult to expect the significant improvement of physical properties of paper only by a single swelling treatment.
