ABSTRACT OF THE DISCLOSURE A unitized, composite, fluid absorbent structure for use in thin, disposable absorbent products such as sanitary napkins, diapers, incontinence pads, adult briefs, wound dressings and the like. The unitized composite, fluid absorbent structure comprises a transfer layer of hydrophilic fibers adhered to a reservoir layer of compressed peat moss material having a higher density than the transfer layer. A diffuse interface is defined between the transfer and the reservoir layers forming a shared, three-dimensional boundary zone containing peat moss material interspersed with hydrophilic fibers. The invention also extends to a method for manufacturing the unitized, composite, fluid absorbent structure and to a method for improving the fluid absorption characteristics of a peat moss sheet.
