Thin And Dry Diaper
First Claim
1. An absorbent core useful for an absorbent article comprising a substrate layer, said substrate layer comprising a first surface and a second surface, said absorbent core further comprising a discontinuous layer of absorbent material, said absorbent material comprising an absorbent polymer material, said absorbent material optionally comprising an absorbent fibrous material and said absorbent fibrous material not representing more than about 20 weight percent of the total weight of the absorbent polymer material, said discontinuous layer of absorbent material comprising a first surface and a second surface, said absorbent core further comprising a layer of thermoplastic material, said layer of thermoplastic material comprising a first surface and a second surface wherein said second surface of said discontinuous layer of absorbent material is in at least partial contact with said first surface of said substrate layer and wherein portions of said second surface of said layer of thermoplastic material are in direct contact with said first surface of said substrate layer and portions of said second surface of the said layer of thermoplastic material are in direct contact with said first surface of said discontinuous layer of absorbent material.

Abstract
An absorbent article, preferably a disposable absorbent article such as a diaper, is disclosed having an absorbent core which imparts increased wearing comfort to the article and makes it thin and dry. The absorbent core useful for an absorbent article comprises a substrate layer, a discontinuous layer of absorbent material, and a layer of thermoplastic material. A second surface of the discontinuous layer of absorbent material is in at least partial contact with a first surface of the substrate layer. Portions of a second surface of the layer of thermoplastic material are in direct contact with the first surface of the substrate layer and portions of said second surface of the layer of thermoplastic material are in direct contact with a first surface of the discontinuous layer of absorbent material. A process for providing a storage layer for an absorbent core useful in an absorbent article is further disclosed.

11. A process for providing a storage layer for an absorbent core useful in an absorbent article, said process comprising the steps of:
-
providing a substrate material comprising a first surface and a second surface; depositing absorbent material onto said first surface of said substrate material in a pattern, the pattern comprising at least one zone which is substantially free of absorbent material, and the pattern comprising at least one zone comprising absorbent material; depositing a thermoplastic material onto said first surface of said substrate material and said absorbent material, such that portions of said thermoplastic material are in direct contact with said first surface of said substrate and portions of said thermoplastic material are in direct contact with said absorbent material. - View Dependent Claims (12, 13, 14, 15, 16, 17)
