ABSTRACT:
An absorbent member in an absorbent article comprises a absorbent polymer and cellulose fibers. The absorbent polymer has a centrifugal retentive capacity for physiological saline of 30 g/g or more and a permeation rate of physiological saline of 10 ml/minute or more. The cellulose fibers are crosslinked cellulose fibers obtainable by an intramolecular and/or intermolecular crosslinking of the cellulose fibers. Particularly, an absorbent member in a sanitary napkin has a centrifugal retentive capacity of pseudo-blood of 30 g or more and a permeation rate of pseudo-blood of 50 ml/minute or more. Also, a topsheet in the absorbent article comprises a liquid-permeable sheet, which comprises at least a layer in contact with a user's skin and a layer not in contact with the user's skin, the layers being overlaid and combined with each other into a unitary body. The layer in contact with the user's skin comprises a porous film of a thermoplastic resin or a nonwoven fabric of synthetic fibers. The layer not in contact with the user's skin comprises an absorbent sheet, which comprises at least bulky cellulose fibers. The absorbent member and the topsheet should preferably comprise crosslinked cellulose fibers.
