Abstract:
An absorbent article comprising a liquid permeable topsheet, a liquid impermeable back sheet and a liquid retentive absorbent member interposed between said topsheet and said back sheet, wherein:said absorbent member comprises an absorbent polymer and cellulose fibers;said absorbent polymer has a centrifugal retentive capacity for physiological saline, which is measured after equilibrium absorption swelling with the physiological saline, of 30 g/g or more, anda permeation rate of physiological saline of 10 ml/minute or more, said permeation rate being measured by introducing 0.05 g of said absorbent polymer into a cylinder having a cross-sectional area of 0.785 cm.sup.2 (inner diameter: 10 mm), allowing said absorbent polymer to absorb and swell with physiological saline until the swelling reaches equilibrium, and thereafter causing physiological saline to permeate through said absorbent polymer; andsaid cellulose fibers are crosslinked cellulose fibers obtainable by an intramolecular, intermolecular, or intramolecular and intermolecular crosslinking of said cellulose fibers.
