Abstract
The characteristic changes in weight, moisture content, and dimension at the early adsorptiondesorption stage of PEG-treated Korean pine (Pinus koraiensis), Japanese larch (Larix kaempferi), mongolian oak (Quercus mongolica) and sargent cherry (Prunus sargentii) woods were investigated. The wood samples were treated with PEG 1000, 2000 and 4000, and conditioned at the relative 98%, 65% and 20% for humidities of one week. The weight of Korean pine, Japanese larch and sargent cherry woods treated with PEG 1000 and 2000 during the adsorption-desorption was significantly changed, but mongolian oak was slightly changed. Moisture content was highly Moisture content was highly fluctuated by the change of relative humidity in the three species except oak wood. Although the weight of PEG-treated wood; however, changes in dimension could be prevented by PEG treatment in all species tested.
