Abstract

Hanji(Korean traditional paper) is made from bark of paper mulberry(Broussonetia kazinoki). For a long time, Hanji has been used in various fields, such as paintings, printing paper, as specialty paper. The utilization of Hanji will become more and more diverse. One of the characteristic properties of Hanji is a long life time comparing to western paper. The mucilage which must be used in Hanji manufacturing should effect the conservation properties of Hanji. The effectiveness of the mucilage in aging of Hanji was evaluated in this paper. Strength properties of thermal aged Hanji made with synthetic mucilage decreased more slowly than those of Hanji made with natural mucilage. As prolonged aging time, all Hanji made mucilage increased oxidation index. But, Hanji made with PAM was most stable in oxidation of cellulose.
