Abstract
An absorbent article (20) having an absorbent core comprising at least about 80% of superabsorbent polymers (SAP) by weight of its absorbent material. An acquisition-distribution system (ADS) (50) is at least partially disposed between the absorbent core and the topsheet. The ADS extends in the longitudinal direction of the absorbent article at least from a point A1 disposed at a distance D from the front edge to a point A2 disposed at a distance D from the back edge of the article, D being equal to 32% of the length L of the article. The ADS has a basis weight which may be at least 20% lower at the point A2 than at the point A1.
Claims13
An absorbent article comprising a front end, a back end and a longitudinal axis extending in a longitudinal direction of the article, the article having a length L as measured along the longitudinal axis between the front end and the back end, the absorbent article comprising:
- a liquid permeable topsheet;
- a liquid impermeable backsheet;
- an absorbent core comprising a core wrap enclosing an absorbent material, the absorbent material comprising at least about 80% of superabsorbent polymers (SAP) by weight of the absorbent material;
- and
- an acquisition-distribution system at least partially disposed between the absorbent core and the topsheet and comprising one or more layers;
- wherein the acquisition-distribution system extends in the longitudinal direction of the absorbent article at least from a point Al disposed at a distance D from the front edge to a point A2 disposed at the distance D from the back edge of the article, wherein the distance D is equal to about 32% of the length L of the article, and wherein the acquisition-distribution system has a basis weight which is lower at the point A2 than at the point A1;
- wherein the acquisition-distribution system further comprises a first zone Z1 disposed towards the front end and encompassing point A1, and a second zone Z2 disposed towards the back end and encompassing point A2;
- wherein the first zone Z1 comprises a homogenous basis weight and a surface area of at least 50 cm2 and the second zone comprises a surface area of at least 10 cm2 and a homogenous basis weight or a gradually, linearly decreasing basis weight;
- wherein the acquisition-distribution system comprises an acquisition layer and a distribution layer, and wherein the acquisition layer is disposed closer to the topsheet than the distribution layer, and
- wherein the distribution layer comprises at least about 50% by weight of cross-linked cellulose fibers.
