Description
We evaluated the water and gas adsorption performances of sugi (Cryptomeria japonica D. Don) crosscut and quarter-sawn specimens, which were given three or six repetitions of dry-and-wet treatments under the room temperature or high temperature conditions. Equilibrium moisture content of all specimens decreased with the progress of repeated wet-and-dry treatments, regardless of the effect of heating. On the other hand, amounts of nitrogen gas adsorption increased with the progress of repeated wet-and-dry treatments, especially in the quarter-sawn specimen. These phenomena, observed in both water and nitrogen gas adsorption, suggest that repeated drying and re-swelling decreased the amount of hydrophilic regions such as noncrystalline cellulose at the microscopic level. It is also considered that cracks and pores would arise on the surface of wood cell walls at the submicroscopic level.
