Why does wood veneer shrink after drying?

During the drying process, the volume of the wood will shrink due to the loss of internal moisture, so the wood will shrink after drying. This is because after the moisture in the wood evaporates, the fibers in the wood become more compact, resulting in a reduction in the volume of the wood. In addition, the shrinkage rate of wood is also related to the type of wood, moisture content, drying method and other factors. Therefore, it is necessary to control the temperature and humidity during the drying process to avoid excessive shrinkage of the wood and affect its quality.
