发明名称 FLUID PERVIOUS WEB EXHIBITING A SURFACE ENERGY GRADIENT
摘要 <p>The present invention pertains to a fluid pervious web comprising a first surface and a second surface. The web is particularly well suited for use as a topsheet on a disposable absorbent article. The first and said second surfaces are separated from one another by an intermediate portion. The first surface of the web exhibits a surface energy less than the surface energy of the intermediate portion. In a preferred embodiment, the web is an apertured formed film. The intermediate portion of the web preferably exhibits a surface energy less than the surface energy of the second surface of the web. The first surface of the web may include a plurality of zones exhibiting different surface energies. The zones may extend in a direction substantially parallel to the longitudinal axis of the web. In another embodiment, the web of the present invention is a coated, apertured, nonwoven web comprising a first surface and a second surface.</p>
