Abstract
An absorbent article, e.g. or a diaper, is disclosed which comprises a composite structure of a "two-dimensional" or very flat, apertured film or nonwoven layer, in combination with a fluid transferring layer and a superabsorbent polymer-containing laminate, and an absorbent core below the laminate to achieve superior dryness. The superabsorbent polymer-containing laminate, which contains airlaid fibrous components and superabsorbent polymers, swells to at least three times its dry caliper upon fluid introduction in order to achieve movement of the coverstock away from the absorbent core which permits the coverstock to remain relatively dry and avoids rewetting.
