Abstract
A method for the manufacture of products containing fibers of lignocellulosic material which involves the disintegration of a lignocellulosic material into fibers and forming and pressing of the fiber web into the product in question, which is preferably in the form of fiberboard (board products). The material that forms the fibers is impregnated with lignin in conjunction with water and at a pH which does not substantially exceed 12.5. When the lignin has been absorbed by the material it is fixed against leaching by water through the modification of said lignin into an essentially water-insoluble form.
