Absorbent bed pad

Abstract

An absorbent bed pad comprises a liquid-impervious sheet which is adhered to an absorbent fabric throughout the interface therebetween. The fabric is unitary and highly stable and is formed from a mixture of long and short fibers. The mixture of fibers varies throughout the depth of the fabric to produce a short fiber-enriched face to be adhered to the impervious sheet and a long fiber-enriched face at the outer face. The fabric is through-bonded and may be adhered by adhesive to the backing sheet to produce compaction of the short fiber-enriched face. In other embodiments the fabric may be treated to increase the wettability of selected portions and a highly compacted, densified layer may be formed integral with the short fiber-enriched face. The method of producing the bed pad of the invention includes the adherence of the backing sheet to the short fiber-enriched face of the fabric by the application of adhesive or by the direct extrusion of the backing sheet onto the short fiber-enriched face without the use of adhesive.
