ABSTRACT:
A cover for a sanitary napkin or other absorbent product is provided which includes an outer layer of a hydrophobic material. The outer layer contains fluid passageways which are small enough so that the outer layer alone will not pass liquid therethrough. A second, liner layer is bonded to the interior surface of the outer layer and is comprised of a nonwoven web which is at least slightly wettable so as to draw liquids through the passageways of the outer layer. The liner layer contains large capillaries so that at least a majority of the liquid entering the liner layer from the fluid passageways will pass through the liner to the absorbent core of the product.
