Abstract
A disposable absorbent core comprises first and second absorbent layers each comprising an absorbent particulate polymer material such that the absorbent particulate polymer material is substantially continuously distributed across an absorbent particulate polymer material area. A disposable absorbent article and method for making the absorbent core are also disclosed.
Claims18
A disposable absorbent article comprising:
- a chassis including a topsheet and a backsheet;
- and
- a substantially cellulose free absorbent core located between the topsheet and the backsheet and including first and second absorbent layers, the first absorbent layer including a first substrate and the second absorbent layer including a second substrate, the first and second absorbent layers further including superabsorbent particulate polymer material deposited on said first and second substrates and thermoplastic adhesive material covering the absorbent particulate polymer material on the respective first and second substrates, said first and second absorbent layers combined together such that at least a portion of said thermoplastic adhesive material of said first absorbent layer contacts at least a portion of the thermoplastic adhesive material of said second absorbent layer, the absorbent particulate polymer material is disposed between the first and second substrates in an absorbent particulate polymer material area, and the absorbent particulate polymer material is substantially continuously distributed across the absorbent particulate polymer material area.
An absorbent core comprising first and second absorbent layers, the first absorbent layer including a first substrate and the second absorbent layer including a second substrate, the first and second absorbent layers further including absorbent particulate polymer material deposited on said first and second substrates and thermoplastic adhesive material covering the absorbent particulate polymer material on the respective first and second substrates, said first and second absorbent layers combined together such that at least a portion of said thermoplastic adhesive material of said first absorbent layer contacts at least a portion of the thermoplastic adhesive material of said second absorbent layer, the absorbent particulate polymer material is disposed between the first and second substrates in an absorbent particulate polymer material area, and the absorbent particulate polymer material is substantially continuously distributed across the absorbent particulate polymer material area, wherein the absorbent core is substantially cellulose free.
