  • Fluid transport webs exhibiting surface energy gradients
    Patent number: 6231948
    Abstract: The present invention pertains, in a preferred embodiment, to a fluid-pervious web comprising a first or wearer-contacting surface and a second or garment-facing surface. The web is particularly well suited for use as a topsheet on a disposable absorbent article. The first and second surfaces are separated from one another by an intermediate portion. The first surface of the web provides a structure which exhibits a surface energy less than the surface energy of the intermediate portion. In a preferred embodiment, the web exhibits a plurality of regions of comparatively low surface energy which define surface energy gradients where they interface with higher surface energy web surfaces. More particularly, the present invention pertains to a fluid-pervious web having a plurality of small-scale surface energy gradients which are oriented and located so as to effectively transport fluid away from the first or wearer-contacting surface.
    Type: Grant
    Filed: April 11, 1997
    Date of Patent: May 15, 2001
    Assignee: The Procter & Gamble Company
    Inventors: William R. Ouellette, Yann-Per Lee, A. Renee Haney, Frederick M. Langdon, John B. Burchnall
