An absorbent member containing a hydrophobic material subjected to hydrophilic treatment, a plurality of through holes passing through the absorbent member in a thickness direction formed at a portion of the absorbent member in a target region (P). The absorbent member has a layer-stacked structure of a plurality of layers, stacked in the thickness direction. The Klemm water absorption height of a lower layer most proximal to the backsheet is higher than that of an upper layer most proximal to the topsheet. The backsheet contains a moisture permeable film including a plurality of microvoids, and having water repellent portions formed by water repellent finishing, on a portion in the target region (P) of a skin-facing surface of the moisture permeable film. A ratio of the total area of portions on which the water repellent finishing is performed to the area of the target region (P) is from 30% to 60%.

Absorbent article with klemm gradient and water repellent finishing

An absorbent articlehas an extensible absorbent memberand is extensible as a whole. The absorbent memberhas three-dimensionally dispersed therein a large number of small absorbent clustersorcontaining a superabsorbent polymerand fibers. The small clustersorare dispersively arranged in a web containing crimped fibers. The small clusters include those composed of a superabsorbent polymer particleand a large number of fibersadhered to the particleand those composed of a helically crimped fiber, a superabsorbent polymer particle, and fibers, the polymer particleand the fibersbeing taken into the helix of the crimped fiber

Absorbent article

An absorbent article having a liquid permeable top layer, a liquid impermeable leakproof layer, and a liquid retentive absorbent layer interposed between the layers, wherein the absorbent layer has an odor-controlling member containing (a) 20 to 80% by weight of specific hydrophilic fiber or hydrophilic foam and (b) an odor-controlling agent, the odor-controlling memberbeing composed of a layer made up of a mutually dispersing mixture of component (a) and component (b) or being composed of adjacent layers separately comprising component (a) and component (b).

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.

A sheet which gives an absorbent article improved recovery from distortion is disclosed. The sheet has a recovery force of 0.7 cN or more in the cross direction, a compressive strength of 100 cN or less, and a basis weight of 20 g/mor more.

Sheet for absorbent article and absorbent article using the same

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.

The present invention provides an absorbent article,having a substantially elongate configuration, comprising a liquid-impermeable leakage-preventive layer,, and a liquid-retentive absorbent layer,disposed above the leakage-preventive layer,, wherein the absorbent layer,comprises a liquid-retentive absorbent member,and a liquid-permeable topsheet,, and is formed by a fixed portion,and one pair of left and right free edge portions,, the fixed portion,being fixed to the leakage-preventive layer,, the free edge portions,being located on opposite left and right sides in the longitudinal direction of the fixed portion,and each having a free end,, the absorbent member,being present in both of the fixed portion,and the pair of left and right free edge portions

Absorbent article with free edge portions

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 including a liquid-retentive absorptive layer formed on a liquid-impermeable, leak-preventive layer in a substantially elongated configuration, the absorbent layer including a liquid-permeable top sheet and a liquid-retentive absorbent member, and the absorbent article is provided longitudinally with left and right opposite side portions containing elastic members which extend in the longitudinal direction thereof, wherein the elastic members are covered with an elastic member-attached sheet provided on an inner surface side of the top sheet.

An absorbent article having a liquid permeable topsheet, a liquid impermeable backsheet, an absorbent member interposed between the topsheet and backsheet, and a moisture absorbent material, wherein the amount of moisture absorption per unit area of the absorbent article is not less than 7.2.times.10.sup.-4 g/hr.cm.sup.2, and a total amount of moisture absorption of the absorbent article is not less than 0.10 g/hr in an environment of 35.degree. C./75% RH.

An absorbent article comprising a liquid permeable outer material, a liquid retentive absorbent article and a liquid-impermeable antileakage material, and formed in a substantially vertically elongated shape, wherein the absorbent element comprises a diffusing absorbent sheet and an absorbent retentive sheet positioned at the rear of the diffusing absorbent sheet and:
