摘要:
An absorbent article comprising a liquid permeable topsheet, a liquid impermeable backsheet, and a liquid retentive absorbent layer is disclosed. The absorbent layer comprises a superabsorbent polymer and hydrophilic fiber or foam that does not swell with water or hydrophilic fiber or foam that has a water retention of 0.7 g/g or less when it is swollen with water and then dewatered by centrifugation. The absorbent article has a physiological saline fixing ratio of 90% or more when it absorbs 10 g of physiological saline and, after 5 minutes, is dewatered by centrifugation.
