摘要:
The present invention relates to layered bodies consisting of at least one plastic foam and/or latex foam layer and particulate, superabsorbent polymers for the absorption of water and aqueous liquids, which bodies comprise the superabsorber on, between, or below the foamed plastic and/or latex layer in a quantitatively and/or locally predetermined and fixed areal configuration at a quantity ratio of plastic and/or latex foam to the superabsorber of 1:500 to 50:1. The plastic/latex foam may comprise fillers, pigments and/or synthetic fibers. The layered bodies have an increased absorption capacity for water and aqueous liquids; in particular under load. They are manufactured by spreading out the foam, applying the superabsorber in the predetermined quantity ratio, optionally by using a stencil, and by fixing it by means of a heat treatment. These layered bodies are used in hygienic articles, as components in natural or artificial soils, as insulating material for pipes and ducts, primarily for cables and constructional elements, as liquid-absorbing and liquid-storing component in packaging materials, and as a part in garments.
