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.

Claims (19)

1. 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.

2. The method of claim 1 , wherein the basis weight of the acquisition-distribution system is at least about 20% lower at the point A2 than at the point A1.

3. The method of claim 1 , wherein a basis weight of the acquisition layer is equal at point A1 and point A2.

4. The method of claim 1 , further comprising the step of profiling the acquisition-distribution system in the transversal direction.

5. 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 and a distribution layer, 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.

6. The method of claim 5 , wherein the acquisition layer comprises a nonwoven.

7. The method of claim 5 , further comprising the step of profiling the acquisition-distribution system in the transversal direction.

8. The method of claim 5 , wherein a basis weight of the acquisition layer is equal at point A1 and point A2.

9. The method of claim 5 , wherein the distribution layer comprises chemically cross-linked cellulosic fibers.
