<p>A flexible fluid-tight material web, particularly for protective clothing or personal care articles, out of a two or multi-layer composite comprising a porous sheet backing, for example a carrier fleece, where a fluid-tight layer is arranged on the backing, characterized in that the fluid-tight layer is a hot melt adhesive film applied in hot condition to the backing. A method of producing a highly absorbent flexible material web of two or more composite layers, the material web comprising a porous sheet backing, a fluid-tight layer being arranged on the backing, comprising the method steps of: applying a hot melt film onto the porous backing; powdering super absorber polymer powder directly onto the still hot melt of the hot melt film; applying a cover layer to the hot melt film and super absorber polymer powder; and bonding the layers by calandering.</p> |
