    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.

    Abstract: The invention relates to novel keratin-binding protein active substances, and also to the production and use thereof. Particularly suitable keratin-binding polypeptides are sequences which are contained in human desmoplakin or are derived therefrom by altering the human desmoplakin polypeptide sequences such as amino acid insertions, substitutions or deletions. The polypeptide sequences of the human desmoplakin is represented in SEQ ID NO: 1. A suitable keratin-binding domain (domain B) is the polypeptide sequence SEQ ID NO: 1, position 2193 2481, in addition to functional equivalents thereof. An additional keratin-binding domain (domain C) is the polypeptide sequence SEQ ID NO: 1, position 2606 2871 and the functional equivalents thereof.

    Abstract: A process for the production of sheets of paper, board and cardboard is provided. The process comprises the addition of at least one cationic polymeric retention aid or a retention aid system comprising the at least one cationic polymeric retention aid to a paper stock, draining the paper stock on a wire with sheet formation, and drying of the sheets. An endo-.beta.-1,4-glucanase is metered in an amount of from 0.00001 to 0.01% by weight, based on the dry weight of the paper stock, into the paper stock before the addition of the at least one cationic polymeric retention aid or retention aid system. Sheets of paper, board or cardboard produced by this process.
