초록

After the revision of management law regarding public records and with the establishment of presidential records management law in Korea, the scale and volume of record collection have increased. As the collected records tend to be diverse in nature, the preservation techniques used for the vital national archives have also been reviewed. In this study, the fibrous raw materials of paper used for long term storage of important national archives were investigated. The optimal digestion conditions of domestic white inner layer of paper mulberry and the physical properties of woody and non-woody fibers such as SwBKP, HwBKP, abaca, Samjidak and domestic paper mulberry fibers were examined for machine-made Hanji. Digestion conditions of domestic white inner layer of paper mulberry were efficient for active alkali dosage 10% for 60 minutes in terms of screened yield, brightness, degree of polymerization, and shive content. The physical fiber properties such as average fiber length, fiber length distribution, WRV (Water Retention Value) and chemical composition were evaluated to obtain optimum mixing ratios with domestic paper mulberry fibers. As a result, the mixing ratio of 80% domestic paper mulberry fibers and 20% SwBKP was found to be satisfactory in the mechanical and structural properties of machine-made sheet, in the stable supply and demand of fibrous raw materials, and in the lower cost of production.
