The present invention relates to an incontinence article for absorption of bodily excretions, comprising an at least regionally liquid-permeable topsheet, a substantially liquid-impermeable backsheet, and an absorption body arranged between the topsheet and the backsheet, the incontinence article comprising a pH regulator between the topsheet and the backsheet at least regionally, characterized in that the pH regulator comprises monosodium citrate or disodium citrate.

Provided is an absorbent body that, for example, in a case where the absorbent body has been used in an absorbent article, such as a thin disposable diaper, having an absorbent body with a low proportion of fiber material (hydrophilic fibers) such as pulp, enables the absorbent article such as a disposable diaper to have an improved liquid trapping function on second and subsequent urinations over the conventional ones and particularly to have an increased amount of liquid trapped under load on the second and subsequent urinations over the conventional ones. Also provided is a water-absorbing resin that is used in the absorbent body and has an increased absorption capacity under load on the second and subsequent urinations over the conventional ones.

The absorbent body includes a water-absorbing resin having a gel expansion force under a load of 4.83 kPa of 26 N or more.

An absorbent hygienic article for absorbing body fluids, the article including a liquid permeable topsheet, a backing layer and an absorbent core arranged between the topsheet and the backing layer, the topsheet and the backing layer being made from roll materials. The topsheet or an absorbent layer in the absorbent core is constituted by a cellulosic fibrous web, the fibres in the cellulosic fibrous web being constituted by a mixture of cellulose fibres including regenerated cellulose fibres or natural cellulose staple fibres and cellulose pulp fibres, the cellulosic fibrous web being a foam-formed, hydroentangled fibrous web.

An absorbent article (10, 110, 210, 310, 410) can include a waist containment member (54) and an absorbent body (34, 134, 234, 334, 434). The waist containment member (54) can include a proximal portion (76) and a distal portion (78) configured to freely move with respect to the chassis (11) when the absorbent article (10, 110, 210, 310, 410) is in a relaxed configuration to provide a containment pocket (82). The absorbent body (34, 134, 234, 334, 434) can be configured to provide improved access for exudates into the containment pocket (82) of the waist containment member (54).

An absorbent cores includes absorbent material enclosed a core wrap which comprises a liquid permeable substrate layer. The core contains from about 87% to about 100% of superabsorbent polymer and a tube-shaped swelling chamber having a length to width aspect ratio of less than or equal to about 5:1. The area of the core is at least twice the area of the swelling chamber, and the core contains a water responsive immobilizing agent to immobilize the superabsorbent polymer prior to water insult. The tube-shaped swelling chamber is a portion of the absorbent core containing superabsorbent polymer that is delimited by a plurality of continuous permanent seals that each join together overlapping portions of the core wrap and prevent superabsorbent polymer from moving across the seals.

Absorbent cores comprising a core wrap which comprises a liquid permeable substrate layer, the core containing from about 87% to about 100% of superabsorbent polymer and having a funnel-shaped swelling chamber. The area of the core is at least twice the area of the swelling chamber, and the core contains a water responsive immobilizing agent to immobilize the superabsorbent polymer prior to water insult. The funnel-shaped swelling chamber is a portion of the absorbent core containing superabsorbent polymer and delimited by continuous permanent seals. Two permanent continuous seals form first opposing funnel wall segments, wherein first opposing funnel wall segments collectively comprise a first chamber angle about 20° to about 120°, the first chamber angle being the sum of angles formed by each first opposing wall segment with respect to the longitudinal axis.

Disclosed is an absorbent article with biocompostable properties, such as a baby diaper or adult incontinence product. Particularly, the present invention is directed to a biocompostable absorbent sanitary article including a blend of synthetic and bio-based superabsorbent polymers with a high degree of biocompostability. The sanitary article comprises, in one embodiment, at least a top layer, a back layer, and absorbent core, wherein the absorbent core includes a superabsorbent polymer, and wherein at least the superabsorbent polymer is biocompostable.

One aspect of the present invention relates to a coated resin particle including: a water-absorbent resin particle; and a coating layer that coats at least a part of a surface of the water-absorbent resin particle, in which the coating layer contains a water-soluble component in which a solubility in 100 g of water is in a range of 1.0 g or more and 150 g or less at 25° C.

A block copolymer (A) including a vinyl alcohol-based polymer block (b) and an ionic polymer block (c) containing a monomer unit with an ionic group forming a salt and a vinyl alcohol-based monomer unit. The ionic group is a carboxylic acid group, a sulfonic acid group, or an ammonium group. The vinyl alcohol-based polymer block (b) has a number-average molecular weight (Mn.sub.b) from 15,000 to 220,000. The ionic polymer block (c) has a content of the vinyl alcohol-based monomer unit from 5 to 95 mol % based on the total monomer units. The block copolymer (A) has a number-average molecular weight (Mn.sub.A) from 20,000 to 440,000. A ratio (Mn.sub.b/Mn.sub.A) of the number-average molecular weight (Mn.sub.b) to the number-average molecular weight (Mn.sub.A) is from 0.1 to 0.9.
