Abstract

After drying to a moisture quotient below the fibre saturation point, wood is treated by heating to 120-150 DEG C, in order to soften the lignin component, after which the wood is compressed by pressing at a temperature of 120-150 DEG C and at a pressure of 5-30 MPa. In this way, the strength of the wood is increased to a remarkable degree and, at the same time, a more hydrophobic product is obtained.
