US Patent 6869670 Composites material with improved high viscosity fluid intake

A liner system suitable for use in personal care absorbent products having a composite material including a substructure applied to a first layer. The first layer and the substructure define a plurality of voids for accommodating passage of fluids through the composite material. In one embodiment, high viscosity fluids including the particles contained therein pass through a plurality of apertures in the first layer. The voids defined by the first layer and the substructure entrap the particles to accommodate passage of fluids through the composite material.
