In this study, the physical, optical, and morphological properties of the lining paper treated by cooking chemicals and ‘Hobun’ after humid accelerated aging were examined using the scanning electron microscopy (SEM) and the energy dispersive X‐ray spectroscopy (EDS). Both SEM analyses and density measurements show that the fiber network of paper cooked by soda ash is denser than that by natural ash, but the fiber of the paper cooked by the former is more damaged than that by the latter. Compared with the paper cooked by soda ash, the paper by natural ash generally has a stronger physical property but a lower optical property. And SEM/EDS analyses of ‘Hobun’ show that major component of ‘Hobun’ is calcium carbonate. In the SEM imagery, it is observed that both the fiber network of both the surface and inside of the paper is filled with ‘Hobun’ and that the more ‘Hobun’ the paper contains, the denser its surface is. These results indicate that calcium carbonate in ‘Hobun’ enhances the optical and surface properties of the lining paper. According to the SEM imagery, after humid accelerated aging, however, the fiber and fiber network of lining paper become seriously damaged with the weakened fiber bonding of the lining paper as well as with the considerable decrease in the amount of protective ‘Hobun’.
