Impact of high temperature drying process on beech wood containing tension wood

The technology of high temperature drying has a great inuence on dimensional and selected physical changes in tension wood. Article is focused on the measurement properties such as moisture content, color changes and longitudinal warping. The quality of beech wood is determined based on structure and properties of wood, frequency of defects in wood material. The tension wood is considered as an important wood defect causing negative alterations in solidwood quality and limits industrial application ofwood. The dierent values of longitudinalwarpingwhichwere measured after dryingwere higher in tensionwood than in normalwood. Impact of radial and tangential angle of growth rings is non-signicant factor.
