  • Patent number: 5836929
    Abstract: A diaper or other absorbent article may include an absorbent body comprising in sequence from the top (the surface adjacent the wearer's body). An upper assembly (2, 3, 4, 5) comprising an acquisition layer (3) formed of first fibrous material substantially free of superabsorbent material, a superabsorbent layer (5) consisting substantially only of first superabsorbent material having a Gel Layer Permeability value of at least about 4 ml/cm.sup.2 /sec and which is present in an amount of about 20 g/m.sup.2 to 320 g/m.sup.2, a storage assembly (6, 7, 8) that includes second superabsorbent material (7) having an absorption against pressure of at least 15 g/g at 50 g/cm.sup.2 and which comprises an upper storage layer (6) and a lower storage layer (7) containing at least 70% by weight of the total amount of second superabsorbent in the upper and lower storage layers and which has a thickness which is the same as or less than the thickness of the upper storage layer (6).

  • Patent number: 5762641
    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.
