Abstract
The present invention relates generally to an absorbent composite for an absorbent article, and more particularly to an absorbent composite comprising fibrous material and superabsorbent material having a Column Absorbency Under Load (CAUL) above 10 g/g. Such an absorbent composite provides a superabsorbent material having superior AUL and permeability, thereby providing improved absorption and rewetting properties. An absorbent article that contains such a composite provides improved ability to absorb and retain fluids, thus preventing excessive rewetting and leakage and making the article more comfortable to wear.
Claims41
An absorbent article having a longitudinal dimension and a lateral dimension comprising:
- a top sheet;
- a back sheet;
- and
