The Study of Restoration Technique of Wax-Treated Volume for the Annals of the Joseon Dynasty (III)-Evaluation of Durability of Korean Traditional Paper using Moist-heat Aging Treatment-

Abstract

To explore the paper materials for restoration of the Annals of the Joseon Dyansty, durability of the three type of the traditional Korean Papers were estimated in this study, through moist heat artificial aging test. Three types(D, F, and G) which showed the best preservation performance in dry heat and UV treatment in the previous study were selected and artificial accelerated aging treatment with moist-heat process was conducted; the viscosity change rate was D G F; folding endurance G D F; L* value F D G; a* and b* change rate D G F; brightness decrease rate D G F, suggesting paper F showed the least change rate in physical/optical properties. Also the CLSM image observation showed fair coherence among fibers and confirmed paper mulberry. And in FDI extraction from each sample, paper F showed the highest value. Overall, paper F (traditional glossy paper) showed the highest stability against thermal treatment. It
