摘要:
A process for the production of paper, board and cardboard by draining a paper stock on a wire in the presence of at least one cationic polymeric retention aid and/or retention aid system with sheet formation and drying of the sheets, wherein an endo-β-1,4-glucanase is metered in an amount of from 0.00001 to 0.01% by weight, based on the dry paper stock, into the paper stock before the addition of the at least one cationic polymeric retention aid and/or retention aid system.

摘要:
The present invention relates to a novel pulp composition for paper or solid board production comprising an oxidized recovered paper pulp and/or an oxidized mechanical pulp into which from 1 to 500 mmol of carboxyl groups per kg and from 1 to 200 mmol of aldehyde groups per kg have been introduced by oxidation. The invention also relates to paper and solid board based on such a pulp composition and also to a process for producing such paper or solid board. The invention also relates to the use of oxidized recovered paper pulp and/or oxidized mechanical pulp for improving the retention and drainage properties of a pulp suitable for producing paper or solid board. The invention further relates to the use of oxidized recovered paper pulp and/or oxidized mechanical pulp for improving, i.e., increasing, the dry strength of paper and solid board.
