ABSTRACT:
A fluid pervious topsheet suitable for use on an absorbent article is disclosed. The topsheet includes an apertured, three-dimensional, macroscopically expanded, fluid pervious web having a textured wearer-contacting surface. The composite web permits liquids to penetrate while providing an improved, less plastic-like feel and visual aesthetics. The process of the present invention, in one embodiment, comprises extruding a polymeric film onto a forming structure, applying a pneumatic pressure to the film to cause the film to be urged into substantial conformance with the forming structure, and depositing a particulate material on said film while the film is in a semi-molten state. In another embodiment, the process of the present invention comprises extruding a polymeric film onto a forming structure, depositing a particulate material on the film while the film is in a semi-molten state to form a composite web, and applying a pneumatic pressure to the film to cause the film to be urged into substantial conformance with the forming structure.
