Abstract
The present invention relates generally to an absorbent core for an absorbent article, and more particularly to an absorbent core having zoned absorbency due to specific placement of adhesives or specific lack of adhesive. Such absorbent cores provide the flexibility of creating precise zoning of particular properties throughout the core, and they provide improved comfort and fit.
Claims77
An absorbent article having a longitudinal dimension and a lateral dimension comprising:
- a top sheet;
- a back sheet;
- and
- a absorbent laminate core disposed at least partially between the top sheet and the back sheet;
- wherein the absorbent laminate core is comprised of:
- an upper layer;
- a lower layer;
- and
- a central absorbent layer including a mixture of tow fibers and SAP disposed between the upper and lower layer, and wherein the absorbent laminate core contains areas of varying absorbency due to varying concentrations of SAP throughout the cross-section of the laminate core.

An absorbent laminate comprising:
- an upper layer;
- a lower layer;
- and
- a central absorbent layer including a mixture of tow fibers and SAP disposed between the upper and lower layer,
- wherein the absorbent laminate contains areas of varying absorbency due to varying concentrations of SAP throughout the cross-section of the laminate.
2 more elements
A method of making an absorbent article comprising:
- a) preparing a top sheet and a back sheet;
- b) preparing an absorbent laminate core by:
- b1) providing an upper layer;
- b2) providing a lower layer;
- b3) providing a central absorbent layer that comprises a mixture of tow fibers and superabsorbent polymer (SAP);
- and
- b4) disposing the central absorbent layer at least partially between the upper layer and the lower layer;
- and
- c) disposing the absorbent laminate core at least partially between the top sheet and the back sheet,
- whereby the absorbent laminate core is prepared in such a manner that it contains areas of varying absorbency due to varying concentrations of SAP throughout the cross-section of the laminate core.
