  • Patent number: 5810972
    Abstract: A method for the manufacture of creped hygienic cellulose paper, in particular. A hemicellulose containing additive, in particular galactomannan, xylan or highly milled birch pulp, is added to the pulp either prior to the pulp being deposited on the wire of the paper machine, after the pulp is deposited on the wire of the paper machine, or both before and after the pulp is deposited on the wire. As a result of this measure, the strength of the paper web thus produced and its runnability properties are substantially improved, while the softness virtually remains unchanged. In addition, the energy requirements for drying the paper web are substantially reduced.
