    摘要: The present invention is an absorbent structure with an ultimate fluid storage member, comprising superabsorbent material at a relatively high concentration whereby the superabsorbent material has a good Performance under Pressure performance as well as a good Saline Flow conductivity. Further, the absorbent structure comprises a non-woven wrap sheet comprising small diameter fibers, which is in direct fluid communication with said storage member, and which has low strike-through times in a repeated modified strike through test.

    摘要: 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.

    摘要: The invention relates to an absorbent gelling material comprising a dry mixture of at least a first type of hydrogel-forming particles and a second type of hydrogel-forming particles. The absorbent gelling material in accordance with the invention is characterized in that the first type of hydrogel-forming particles has an Absorption Against Pressure value which is higher than the Absorption Against Pressure value of the second type of hydrogel-forming particles, the weight of the second type of hydrogel-forming particles forming at least 10% of the combined weight of the first and second type of hydrogel forming particles. The invention also relates to a method for making such material.
