Abstract

The present invention relates to a novel fibrous composition for paper or card production, which contains an oxidized wastepaper stuff and/or an oxidized mechanical stuff into which 1 to 500 mmol of carboxyl groups per kg and 1 to 200 mmol of aldehyde groups per kg were introduced by oxidation. The invention also relates to paper and card based on such a fibrous composition and also to a process for producing such a paper or card. The invention also relates to the use of oxidized wastepaper stuff and/or oxidized mechanical stuff to improve the retention and drainage properties of a stuff suitable for the production of paper or card. The invention further relates to the use of oxidized wastepaper stuff and/or oxidized mechanical stuff to improve, i.e. enhance, the dry strength of paper and card.

Claims (22)

1. A pulp composition for paper or solid board production, comprising a) at least one chemical pulp A, and b) at least one oxidized pulp B in which, by oxidation of at least one conventional pulp selected from the group consisting of recovered paper pulp, mechanical pulp and mixtures thereof, from 1 to 500 mmol of carboxyl groups and from 1 to 200 mmol of aldehyde groups per kg of conventional pulp have been introduced, and c) at least one further conventional pulp C other than A and B;
wherein the total amount of the constituents A and B accounts for from 30% to 80% by weight of the entire pulp mass in the pulp composition, and the constituents A, B and C account for at least 70%, more particularly at least 80%, of the entire pulp mass in the pulp composition, each reckoned as oven dry material.
2. The pulp composition according to claim 1 wherein the molar ratio in the oxidized pulp of the aldehyde groups introduced to the carboxyl groups introduced is not more than 1:1.
3. The pulp composition according to either of the preceding claims, comprising the oxidized pulp B and the pulp C in a total amount of 70% to 98% by weight, based on the total weight of the pulp mass in the pulp composition.
4. The pulp composition according to any preceding claim wherein the oxidized pulp accounts for at least 50% by weight, based on the total amount of oxidized pulp B
and chemical pulp A.
5. The pulp composition according to any preceding claim wherein the oxidized pulp is selected from an oxidized recovered paper pulp.
6. The pulp composition according to any preceding claim wherein the pulp C is selected from conventional mechanical and thermomechanical pulp and conventional recovered paper pulp.
7. The pulp composition according to any preceding claim wherein the oxidized pulp is obtainable by oxidation of a conventional pulp with oxygen in the presence of a laccase.
8. The pulp composition according to claim 7 wherein the oxidation is carried in the additional presence of a redox mediator.
9. The pulp composition according to claim 8 wherein the redox mediator is a sterically hindered amine oxide compound.
10. A paper stock wherein the fiber constituents are a pulp composition according to any one of claims 1 to 9.
11. A paper or solid board based on a pulp composition according to any one of claims 1 to 9.
12. A process for producing a paper or solid board, comprising i) producing an aqueous fiber suspension comprising a) at least one chemical pulp A, and b) at least one oxidized pulp B in which, by oxidation of at least one conventional pulp selected from the group consisting of recovered paper pulp, mechanical pulp and mixtures thereof, from 1 to 500 mmol of carboxyl groups and from 1 to 200 mmol of aldehyde groups per kg of conventional pulp have been introduced, and c) at least one further conventional pulp C other than A and B, comprising suspending the pulps in water and optionally adding customary additives and fillers, and ii) draining the fiber suspension in a paper machine to form paper or solid board, wherein the relative amount of the pulps are chosen such that the total amount of the constituents A and B accounts for from 30% to 80% by weight of the entire pulp mass in the fiber suspension, and the total amount of the constituents A, B
and C accounts for at least 70% of the entire pulp mass in the pulp composition, each reckoned as oven dry material.
13. The process according to claim 12 wherein the molar ratio in the oxidized pulp of the aldehyde groups introduced to the carboxyl groups introduced is not more than 1:1.
14. The process according to claim 12 or 13 wherein the oxidized pulp B and the pulp C account for from 70% to 98% by weight of the total pulp mass in the fiber suspension, each reckoned as oven dry material.
15. The process according to claim 12, claim 13 or claim 14 wherein the oxidized pulp accounts for at least 50% by weight, based on the total amount of oxidized pulp B and chemical pulp A in the fiber suspension.
16. The process according to any one of claims 12 to 15 wherein the oxidized pulp is selected from oxidized recovered paper pulp.
17. The process according to any one of claims 12 to 16 wherein the pulp C is selected from conventional mechanical and thermomechanical pulp and conventional recovered paper pulp.
18. The process according to any one of claims 12 to 17 wherein the paper is writing or printing paper.
19. The process according to any one of claims 12 to 17 wherein the paper is packaging paper.
20. The process according to any one of claims 12 to 17 wherein solid board is concerned.
21. The use of an oxidized pulp B in which, by oxidation of at least one conventional pulp selected from the group consisting of recovered paper pulp, mechanical pulp and mixtures thereof, from 1 to 500 mmol of carboxyl groups and from 1 to 200 mmol of aldehyde groups per kg of conventional pulp have been introduced, for improving the retention properties of pulp compositions for paper or solid board production which comprise at least one chemical pulp and at least one further pulp selected from mechanical, chemomechanical and conventional recovered paper pulp.
22. The use according to claim 21 wherein the oxidized pulp is selected from oxidized recovered paper pulp.
