Abstract: An absorbent article, such as a diaper, comprising a liquid-permeable topsheet, an upper acquisition-distribution system, an absorbent core comprising a layer of superabsorbent polymer particles disposed in a core wrap and a liquid-impermeable backsheet. The superabsorbent polymer particles are preferably not mixed with cellulose fibers. The upper acquisition-distribution system is substantially free of unbonded cross-linked cellulose fibers. The superabsorbent polymer particles have an UPM value of at least 45 UPM units and preferably an EFFC above 23 g/g. The absorbent core optionally comprise channel-forming areas. The absorbent article optionally comprises a lower acquisition and distribution layer.

Abstract: An absorbent core (28) for use in an absorbent article (20) having a high loft central layer (43) between a top layer and a bottom layer and superabsorbent particles (SAP) at least partially distributed within the high loft layer. The superabsorbent polymer particles have a time to reach an uptake of 20 g/g (SAP T20) of less than 220 s, and/or the absorbent core has a time to reach an uptake of 15 g/g (Core T15) of less than 200 s, and/or the absorbent core has a permeability (core K20) of more than 6.0×10?8 cm2. These properties are measured according to the K(t) Test Method as described in the application.
