Bleached, Mechanical Paper Pulp And The Production Method Therefor

摘要

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