An absorbent article includes a liquid-permeable top layer, a liquid-impermeable back layer, and a liquid retentive absorbent member, interposed between the top layer and the back layer. The absorbent member is arranged to form an opposing pair of barrier cuffs which are within longitudinal edges of the top layer and extend along the longitudinal edges. A pocket portion is formed between the pair of barrier cuffs.

Absorbent article

A deodorizing absorbent sheet having a water-insoluble deodorizer and an absorbent polymer which are embedded in a fiber web, wherein the absorbent polymer is fixed to the fibers making up the fiber web. The deodorizer is fixed inside the fiber web via the absorbent polymer. The deodorizer and absorbent polymer are substantially absent on the surface of the absorbent sheet.

Deodorizing absorbent sheet

An absorbent article includes a liquid-permeable top layer, a liquid-impermeable back layer, and a liquid-retentive absorbent member interposed between the top layer and the back layer. The absorbent member is arranged such that a pair of absorbent barrier cuffs having a prescribed width are formed at respective left and right opposing side portions of the top layer in the width-wise direction thereof, and liquid-shrinkable members, which can elastically shrink upon absorption of liquid, are disposed within the barrier cuffs and extend in the longitudinal direction of the barrier cuffs.

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.

An absorbent article (,) comprising a liquid permeable top layer (,), a liquid impermeable back layer (,), and a liquid retentive absorbent member (,) interposed between the top layer (,) and the back layer (,), wherein the absorbent member (,) includes an absorbent sheet (,) having a thickness of 0.3 mm to 5 mm, the absorbent sheet being arranged such that a barrier cuff having a prescribed width is formed at the central portion of the top layer in the widthwise direction thereof, wherein said absorbent member is provided with liquid shrinkable members, which can elastically shrink upon the absorption of the liquid at the surface of said absorbent member facing said top layer and/or inside said absorbent member and in the vicinity of said surface, such that said absorbent member elastically shrinks over a prescribed length.

Absorbent article with liquid shrinkable elements

An absorbent article which comprises at least a liquid retentive absorbent member and a liquid impermeable antileakage layer, wherein the liquid retentive absorbent member has a bending stiffness of 0.05 to 1.0 gf.multidot.cm along its lateral direction and a compressive modulus of 2.times.10.sup.6 to 1.times.10.sup.8 dyne/cm.sup.2 along its lateral direction.
