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.
Claims9
A method for making an absorbent article, the method comprising the steps of:
- forming an absorbent core by enclosing an absorbent material comprising at least about 80% of superabsorbent polymers (SAP) by weight of the absorbent material within a core wrap;
- providing an acquisition-distribution system having a basis weight which is lower at a point A2 than at a point A1;
- providing a topsheet and a backsheet;
- combining the absorbent core, the acquisition-distribution system, the topsheet and the backsheet such that the point A1 is disposed at a distance D from the front edge of the article and such that the point A2 is disposed at the distance D from the back edge of the article, wherein the distance D is equal to 32% of the length L of the article and
- wherein the acquisition-distribution system comprises an acquisition layer in fibrous form and a distribution layer comprising a nonwoven, wherein the distribution layer is deposited in fibrous form on the acquisition layer, and wherein the distribution layer is deposited at a higher basis weight at the point A1 than the point A2.
