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.
Claims8
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;
- and an acquisition-distribution system at least partially disposed between the absorbent core and the topsheet and comprising two or more layers;
- wherein the acquisition-distribution system extends in the longitudinal direction of the absorbent article at least from a point A1 disposed at a distance D from the front end to a point A2 disposed at the distance D from the back end of the article, wherein the distance D is equal to about 32% of the length L of the article, wherein the acquisition-distribution system has a basis weight which is lower at the point A2 than at the point A1 and wherein the acquisition-distribution system comprises an acquisition layer and a distribution layer and does not comprise superabsorbent polymer, wherein the acquisition layer is disposed closer to the topsheet than the distribution layer and the distribution layer is profiled along the longitudinal axis such that the basis weight of the distribution layer at the point A2 is at least about 20% lower than at the point A1, and
- wherein the acquisition-distribution system comprises a first zone Z1 disposed towards the front end and encompassing point AL, 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 the second zone Z2 comprises a gradually, linearly decreasing basis weight.
