An absorbent member () of the invention has a hydrophilic continuous fiber web () and lumpy particles of an absorbent polymer () held in the web (). The absorbent polymer () is localized in part in a planar or thickness direction of the absorbent member (). The continuous fibers in a region (M) in a planar direction of the web () where the absorbent polymer is distributed are in a state cut into a large number of staple fibers (). A method of producing an absorbent member includes the step of spreading lumpy particles of an absorbent polymer () on a continuous fiber web () and pressing the continuous fibers in part of the web () onto the absorbent polymer () to cut the continuous fibers.

Absorbent member and method of producing the same

The present invention provides an absorbent article capable of suppressing rash of skin in regions which come into contact with a gather portion of the absorbent article, by applying a water-soluble skin care agent and oily skin care agent on the gather portion to be contacted with the skin of a wearer in wearing the absorbent article, and allowing at least a part of the above mentioned oily skin care agent to be transferred to the skin of a wearer when wearing before the above mentioned water-soluble skin care agent is transferred to the skin of a wearer.

Absorbent article

A disposable diaper () comprising a liquid permeable topsheet (), a liquid impermeable backsheet (), and liquid retentive absorbent members (), (), and () interposed between the two sheets, wherein the absorbent members () (), and () are disposed in series in the direction of from the rear portion (B), through the crotch portion (A), to the front portion (C), an elastic member is disposed in its stretched state on both sides of the series of the absorbent members, and the absorbent members (), (), and () are arranged such that a gap is produced between any adjacent two of them when the diaper is stretched flat and that any adjacent two of the absorbent members come into close contact when the diaper is worn.

Disposable diaper

An absorbent article comprises a liquid-permeable topsheet, a liquid-impermeable backsheet and a liquid-retentive absorbent core interposed between the topsheet and the backsheet. The absorbent article is substantially vertically elongated and has an upstanding gather. The topsheet has a liquid shut-off region in a line shape and adapted to prohibit migration of a liquid in the topsheet. The liquid shut-off region is formed at a region outside a peripheral edge portion but other than a joined section between the topsheet and a sheet material for forming the upstanding gather.

An absorbent article comprising a liquid retentive absorbent layer containing a superabsorbent polymer and a liquid-impermeable leak proof layer is disclosed. An agent having a skin care effect and substantially no decomposing action on the superabsorbent polymer is fixed on a prescribed region of the absorbent article in a state ready to be released from that region upon contact with moisture.

An article ( ) for thickening body fluids or excreta which contains a polysaccharide ( ) capable of thickening in the presence of a polyvalent metal ion, the polysaccharide ( ) being present in a state ready to dissolve or be dissociated in the moisture contained in body fluids or excreta.
