Provided is an absorbent article having a top sheet with an opening-formed area in which openings are formed, and non-opening-formed areas in which no openings are formed, said absorbent article being capable of preventing liquid from remaining on the surface of the opening-formed area of the top sheet. In the present invention, the top sheet is a resin sheet having an opening-formed area () in which openings are formed, and non-opening-formed areas () in which no openings are formed. The opening-formed area () is disposed in an outlet-facing area () that faces at least an outlet for fluid from a wearer. The top sheet () has a blood modifier layer on the surface of at least the outlet-facing area (). The blood modifier of the blood modifier layer has an inorganic/organic balance (IOB) of 0 to 0.60, a melting point of not more than 45&#xb0; C., and an aqueous solubility of 0.05 g or less with respect to 100 g of water at 25&#xb0; C.

Absorbent article

The purpose of the present invention is to provide a nonwoven for a top sheet of an absorbent article that is unlikely to stick after having absorbed menstrual blood, that is smooth and dry, and in which the absorbed menstrual blood is unlikely to diffuse on the nonwoven. This nonwoven has the following configuration. A nonwoven for a top sheet of an absorbent article, having a lengthwise direction and a crosswise direction, wherein the nonwoven has a plurality of ridge parts and a plurality of groove parts extending in the lengthwise direction and disposed in alternating fashion in the crosswise direction, the nonwoven being characterized in that the ridge parts and the groove parts have a plurality of through-holes, and the ridge parts have a region containing a blood lubricity-imparting agent that contains a predetermined blood lubricity-imparting agent.

Nonwoven and absorbent article having a blood slipping agent

An absorbent article has a lengthwise direction and a widthwise direction. The absorbent article includes a body section provided with a liquid-permeable top sheet on a skin-side, a liquid-impermeable backsheet on a garment-side, and a liquid-holding absorbent body positioned between the top sheet and the backsheet; and wing sections extending outwardly from both side-edges of the body section in the widthwise direction. A surface of the wing sections on the skin-side is formed by the top sheet or from side sheets positioned on both sides in the widthwise direction of the top sheet. Furthermore, the surface of the wing sections on the skin-side includes a plurality of bending parts extending non-continuously in the lengthwise direction, arranged in the widthwise direction, and having a substantially U-shaped cross-sectional shape in the widthwise direction.

Absorbent article having bent sections

The present invention addresses the problem of providing a novel absorbent article that prevents excessive compression of an absorbent body caused by deformation of the absorbent article, and rewetting associated with said compression. In order to solve such a problem, a sanitary napkin () is provided with a liquid-permeable top sheet (), a liquid-impermeable back sheet (), and an absorbent body () disposed between the top sheet () and the back sheet (), wherein: an extensible area () having an extensible bellows-like section (), and a flexible area () surrounding the extensible area () are formed in a waste supply area () of the top sheet ().

Provided is an absorbent article capable of suppressing leakage in the widthwise direction from an absorbent article () of a bodily fluid () which has seeped from an absorbent body () as a result of the application of pressure to the absorbent article (). The present invention is an absorbent article () having a lengthwise direction (Y-direction) and a widthwise direction (X-direction), and provided with a liquid-permeable top sheet () provided on the skin-side, a liquid-impermeable backsheet () provided on the garment-side, and a liquid-holding absorbent body () provided between the top sheet () and the backsheet () and including edges extending in the lengthwise direction on both sides in the widthwise direction, wherein: at least areas outside both edges of the absorbent body () in the widthwise direction thereof include a plurality of first channels () and a plurality of second channels () for channeling bodily fluid () which has seeped from the absorbent article (); the plurality of first channels () extend in the lengthwise direction and are arranged in the widthwise direction; and the plurality of second channels () connect adjacent first channels ().

An absorbent article is provided to prevent pulp fibers and a superabsorbent polymer that constitute an absorbent body from leaking from openings, even if a top sheet does not cover the side wall portions of the absorbent body at the openings. The absorbent article includes: a liquid-permeable top sheet having openings; a back sheet; and an absorbent body having openings. At the openings of the top sheet and the openings of the absorbent body, the top sheet is detached from the absorbent body. The opening diameters of the openings on the clothing side of the top sheet are smaller than the opening diameters of the openings on the skin side of the absorbent body. An opening diameter of the openings on the clothing side of the absorbent body is no greater than the opening diameter of the openings on the clothing side of the top sheet.
