Absorbent article with high permeability sap

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.
