Abstract
An absorbent device having low fluid wet-back and good surface cleanliness and resistance to staining is provided which comprises an absorbent core, a cover sheet on a body facing side thereof and an intermediate layer between the cover sheet and the core wherein the cover sheet comprises an apertured polymer film for example a flexible polymer net and the intermediate layer comprises a planar apertured polymer film for example a flexible polymer net.
Claims12
An absorbent device having low fluid wet-back, comprising;
- an absorbent core having a body facing side;
- a cover sheet on said body-facing side of said absorbent core;
- and
- an intermediate layer between said absorbent core and said cover sheet;
- wherein said cover sheet comprises an apertured polymer film and said intermediate layer consists essentially of a planar apertured polymer film, and
- wherein said cover sheet and said intermediate layer have open areas, said open area of said cover sheet being greater than said open area of said intermediate layer.
An absorbant device having low fluid wet-back and a high relative brightness, comprising;
- an absorbent core having a body-facing side;
- a body-contacting cover sheet on said body-facing side of said absorbent core, said cover sheet having a body-contacting surface;
- and
- an intermediate layer between said absorbent core and said cover sheet;
- wherein said cover sheet comprises an apertured polymer film and said intermediate layer consists essentially of a planar apertured polymer film;
- the optical brightness of a stained area of said body-contacting surface of said cover sheet and the optical density of an unstained area of said body-contacting surface being comparable.
An absorbent device, comprising an absorbent core having a first surface and an apertured body-facing layer covering said first surface of said absorbent core, said apertured body-facing layer comprising a layered array of two flexible substantially planar polymer nets having apertures defined by integral strands and junctures formed from the polymer material.
A method of producing an absorbent device having low fluid wet-back, comprising at least partially covering a body-facing surface of an absorbent core with a cover sheet and an intermediate layer, said intermediate layer being between said cover sheet and said absorbent core, wherein said cover sheet comprises an apertured polymer film and said intermediate layer consists essentially of a planar apertured polymer film.
