Abstract

A process for producing fiberboard panels includesI. gluing cellulosic fibers with an aqueous glue solutionand adjusting the moisture content of the cellulosic fibers and/or the water content of the glue such that the moisture content of the glued cellulosic fibers is not more than 150%; andII. compressing the glued cellulosic fibers produced in step (I) at elevated temperature to fiberboard panels.
