Absorbent core having improved fluid handling properties

Abstract

An absorbent core comprises, in sequence through it thickness, a first structure comprising an upper layer comprising a first fibrous material having compressibility of at least 5 cm.sup.3 /g and a drip capacity of a least 10 g/g, the structure also comprising a first superabsorbent material having a substantially non-decreasing dynamic swelling rate and a second a structure comprising a second fibrous material and a second superabsorbent material having a dynamic swelling pressure of at least 15 g/g at 10 g/cm.sup.2 (0.7 psi), wherein the dynamic swelling rate of the first superabsorbent material is not greater than 2/3 of the dynamic swelling rate of the second superabsorbent material. The absorbent core allows improved fluid handling of body discharges throughout the core and in the subsequent efficient storage of these discharges.
