Abstract:
This invention relates to bleached mechanical paper pulps, based on fibrillated fibers of cellulose, hemicelluloses and lignin, containing calcium carbonate, in which calcium carbonate is crystallized and at least partly covers the fibrillated fibers of cellulose, hemicelluloses and lignin to which the calcium carbonate is mechanically bonded, papers made from these pulps and their preparation process.
