닥나무류를 이용한 전통한지 제조 기술의 개선에 관한 연구 ( I )

A New Improvement of Traditional Hanji(Korean Paper) Manufacturing Technology from Paper Mulberries

This study was carried out to investigate the papermaking characteristics for New Hanji (Korean Paper) products from paper mulberries by new pulping processes. So far wood ash extractives or NaOH only have been used for cooking chemicals at the atmospheric condition. Also bast fibers only have been used as raw materials for Hanji, In this study, as the alternatives to the conventional cooking, alkali, alkali-peroxide and sulfomethylated cookings were applied at the pressurized condition for Hanji pulping, Also bast fibers, woody parts and whole woods are attempting for being utilize as new raw materials for special Hanji. Anatomical and chemical properties of 3 paper mulberry species and their pulping characteristics were analyzed.
