Abstract

The present invention provides a resilient, fluid-pervious, laminate, plastic web suitable for use as a topsheet on absorbent articles, especially catamenial articles. The web includes a first layer of polymeric material, a second layer of polymeric material and an intermediate layer of fibrous material. The fibrous material of the intermediate layer extends below the second surface of the web, preferably into the absorbent core. In-use, fluid deposited on the topsheet drains or empties more readily as the fibrous material of the intermediate layer breaks up the fluid meniscuses which form along the second surface of the web, thereby providing improved dryness and cleanliness for the user.
