Abstract: Disclosed are superabsorbing foams containing superabsorbing fibers and/or fruit fibers and a method for producing superabsorbing foams having improved wet fastness. According to said method, a cross-linkable aqueous mixture comprising at least 50 mol percent of neutralized, monoethylenically unsaturated monomers containing acid groups or at least one basic polymer, cross-linking agents, superabsorbing fibers, and/or fruit fibers, and at least one surfactant is foamed, whereupon the monomers contained in the foamed mixture are polymerized or the basic polymers are crosslinked, resulting in a foam-type hydrogel being formed. Also disclosed is the use of the foams obtained by means of said method in hygiene products used for absorbing body liquids, bandaging material used for covering wounds, as a sealant, packaging material, soil conditioner, soil substitute, for dewatering mud, thickening aqueous lacquers when disposing of leftover lacquer quantities, dewatering water-containing oils or hydrocarbons, or as a material for filters in ventilation systems.

Abstract: A superabsorbing foam containing synthetic fibers and/or natural fibers selected from:apple, orange, tomato, wheat fibers and/or oat fibers is new. An Independent claim is included for preparation of foam of increased wet strength by foaming a crosslinkable aqueous mixture containing at least 50 mole% neutralized acid groups containing monoethylenically unsaturated monomer, or at least one basic polymer crosslinker, superabsorbing synthetic fibers and/or natural fibers selected from the above group and at least one surfactant, polymerization of the monomers or the basic polymer in the mixture to be foamed, and formation of a foamed hydrogel.
