A combination of hot melt and water-based adhesives (solution resin or latex) is particularly advantageous for bonding fibers together to form a layer and for bonding that layer to an adjoining layer. The water-based adhesive, which need not be crosslinkable, provides fiber-to-fiber bonding through the layer of fibers, while the hot melt adhesive bonds the layer of fibers to the adjoining layer. In preferred embodiments, the layer of fibers is moisture absorbent and formed of wood pulp, cotton, rayon, or cellulose triacetate fibers (possibly with the addition of a small amount of thermoplastic fibers to increase bulk); the fibers can be reprocessed fibers of irregular lengths; the water-based adhesive is a latex, non-crosslinkable adhesive; the adjoining layer is permeable to moisture and made of a nonwoven polyolefin, rayon, polyester, or blend thereof; a moisture-barrier layer (e.g., closed-cell foam or moisture-impervious film) is adhered by hot melt adhesive to the other surface of the layer of fibers; the laminate forms a panty shield.
