Abstract:
1. An absorbent article comprising a liquid permeable top layer, a liquid impermeable leakproof layer, and a liquid retentive absorbent layer disposed there between, wherein said liquid retentive absorbent layer comprises an odor-controlling member containing components (a), (b) and (c): (a) a synthetic hydrophilic fiber having an average fiber diameter of 0.1 to 10 μm that does not swell with water, or a crosslinked cellulose fiber that has a centrifugal water retention of 0.7 g/g or less as measured after equilibrium water absorption and swelling followed by centrifugation, (b) an odor-controlling agent and (c) a superabsorbent polymer, and wherein said odor-controlling member contains a layer or web of component (a) having dispersed therein said superabsorbent polymer (c), wherein the odor-controlling agent (b) is fixedly adhered to the component (a) layer via the superabsorbent polymer (c); wherein said odor-controlling member is an odor-controlling sheet comprising 20 to 80% by weight of said component (a), 10 to 60% by weight of said component (b), and 10 to 60% by weight of said component (c) superabsorbent polymer, and wherein said odor-controlling sheet has a Klemm's water absorption at 1 minute of 40 mm or more as measured according to JIS P 8141 using physiological saline.
