Abstract:
1. 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 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 particulate polymer material is deposited on the first and second substrates in respective patterns of land areas and junction areas between the land areas such that the absorbent particulate polymer material is discontinuously distributed on the first and second substrates; and the first and second absorbent layers are combined together such that the respective patterns of absorbent particulate polymer material are offset from one another; wherein the absorbent core has a front end and a rear end and a longitudinal axis extending from the rear end to the front end and the land areas of the respective patterns are arranged in a grid which is positioned at an angle from about 5 to about 85 degrees from the longitudinal axis of the absorbent core; wherein the width of the land areas is from about 8mm to about 12mm and the width of the junction areas is less than about 5mm; wherein the absorbent core has four absorbent zones disposed along said longitudinal axis of said absorbent core, each of the four absorbent zones having absorbent particulate polymer material present in differing amounts between the four absorbent zones and each of the four absorbent zones is substantially cellulose free; wherein there is a gradual transition in amount of absorbent particulate polymer material from one of the four absorbent zones to another.
