Abstract

Production of wood fiber board comprises feeding bleached fiber (1) as starting material containing wood fibers to a refiner (4) outside of the production plant. Preferred Features: The fiber consists of fiber bundles mechanically abraded from solid wood and single wood fibers. The fiber is chemically bleached with an oxidant which is added to the wood fibers in the refiner. Dyes (2) are added to the wood fibers.
