Abstract
An absorbent article such as a diaper or a sanitary napkin is made up of a facing sheet, an absorbent pad means, and a moisture-impervious backing sheet. The absorbent pad means comprises a fibrous structure having an intermediate densified layer and a layer of highly porous, loosely compacted batt on both sides of the densified layer. The batt layer between the densified fibrous layer and the moisture-impervious backing sheet contains distributed therein a particulate, water-insoluble but water-swellable polymeric absorbent.
