Hygroscopicity of Sugi (Cryptomeria japonicaD. Don) Wood Treated with High Temperature Steam

ISHIKAWA Atsuko and KURODA Naohiro

Abstract
　　Higroscopicity of Sugi (Cryptomeria japonicaD. Don) wood treated with steam at several vapor pressures and temperatures was measured. Equilibrium moisture content (EMC) of the specimens treated with saturated steam was significantly lower than that of the specimens treated with superheated steam. No distinct difference of EMC was observed among the specimens treated with superheated steam at different vapor pressures.

Key words : Sugi (Cryptomeria japonica D. Don), Steam treatment, Vapor pressure, Equilibrium moisture content, Higroscopicity
