Transfer layer for absorbent article

Abstract

Three-dimensional formed films particularly useful as transfer layers in absorbent articles comprise a base plane having land areas defining a plurality of protuberances having sidewalls and a bottom wall, a plurality of the protuberances having an aperture in substantially at least one sidewall. In preferred embodiment, the film further comprises a plurality of capillaries, which can originate in the base plane or in a secondary plane spaced from the base plane. In preferred embodiments, the capillaries terminate in a common plane with the bottom surfaces of the protrusions.

Description

BACKGROUND OF THE DISCLOSURE [0001]The disclosure relates to formed films, more specifically three-dimensional formed films for use as transfer layers in absorbent articles.[0002]Absorbent articles are articles that are generally used once or a limited number of times for the temporary collection of bodily fluids. Such articles include diapers, adult incontinent products, feminine hygiene products, bandages and similar articles. In general, these articles have a topsheet, which is positioned adjacent the skin of the user, a backsheet, which is opposite the topsheet and may, in use, be positioned adjacent to the clothes of the wearer, and an absorbent core positioned between the topsheet and the backsheet. In most instances, the topsheet is pervious to the bodily fluids and the backsheet is impervious to such fluids, thus protecting the clothing of the wearer from leaks. The absorbent core is designed to collect and hold the bodily fluids until the article can be disposed of and chan...

Finally, transfer layers have been known to be used to reduce surface wetness on the topsheet by facilitating transfer of static fluids that would otherwise tend to remain on the topsheet surface and again create a damp, unpleasant feeling.
