Changing wood texture with combination of selective treatment and pressing

Abstract

Abstract Structural and anatomical models of alder wood have been developed on the basis of technical and physical models of wood. The models enable to solve the problem of penetrating changes in wood texture by combining selective treatment (impregnation) with two wood colouring agents in different directions of anisotropy, followed by uneven pressing. Specimens with the texture of mahogany, rosewood, walnut, etc have been obtained. Alder wood is pressed at an angle of 45° to the radial direction to obtain the texture of mahogany, at an angle of 90° – for a texture of rosewood. At the same time, physical and mechanical properties of modified wood correspond to similar indicators of wood of these species. The study of macro-and microstructure of pressed wood suggests that texture of the obtained material corresponds to the texture of rosewood and mahogany. It is possible to imitate any species of valuable wood using the obtained structural models and the developed techniques.
