Abstract of the Disclosure Defiberized lignocellulosic material, such as wood, is treated with a liquid carrier containing an oxidizing agent, and the wet mat thereof is subjected to pressure, and to heat for a sufficient period of time to cause an oxidative reaction among the fibers resulting in a strong interfiber bond. Catalysts or other reaction modifying agents may be employed. By virtue of the enhanced interfiber bonding effect t paper sheets, such as liner board, which are usually formed of delignified cellulosic material, the fibers of which are highly refined, can be formed totally or partially of less expansive sources of material such as ground wood, semi-chemical or semi- mechanical lignocellulosic pulps without sacrifice of strength.
