Effect of Drying Methods on the Discoloration of Three Major Domestic Softwoods in Korea

摘要

Japanese pine. Korean pine and larch are three major softwood species in Korea. Their colors are relatively light, thus easily discolored due to drying and UV irradiation. They were dried with five different drying methods, steaming treated, and weathered. And their colors were measured using a spectrophotometer and compared between species and drying methods. For Japanese and Korea pines HD and ST specimens show distinct color differences comparing with the controls. Steaming treatment discolored the dried specimens of Japanese and Korean pines but didn't those of larch. After weathering for 144 days the specimens of Japanese pine shows slight color difference between the drying methods.
