Abstract: The present invention is directed to a matched permeability liner/absorbent structure system, suitable for use in absorbent articles, in which the permeability of the bodyside liner is correlated with the permeability of the subjacent layer of the absorbent structure, such as a surge layer. The inventors have observed that by appropriately matching the permeability of the liner material to the permeability of the subjacent layer, liquid intake performance of the liner and subjacent layer materials can exceed liquid intake performance of the subjacent layer material alone. Thus, in accordance with an embodiment of the present invention, the permeability of the bodyside liner is set within a specified range of that of the subjacent layer such that the liner/subjacent layer liquid intake performance is improved.
