A signal layer for an absorbent article provided to absorb menstrual fluid includes a pattern of capillary channels allowing capillary action such that discharged menstrual fluid that comes across one of the openings in the capillary channels enters into the capillary channels and is retained therein due to the capillary force. The color of the retained menstrual discharge dyes or colors the pattern for signaling purpose, and the pattern is directly or indirectly visible to an observer.

An object of the present disclosure is to provide an absorbent article without a sticky feel on the top sheet and with a smooth top sheet, not only when a large amount of menstrual blood has been absorbed, but even when a small amount of menstrual blood has been absorbed. The absorbent article of the present disclosure is as follows. An absorbent article comprising a liquid-permeable top sheet, a liquid-impermeable back sheet and an absorbent body between the liquid-permeable top sheet and liquid-impermeable back sheet, wherein the liquid-permeable top sheet comprises a blood slipping agent having a kinematic viscosity of 0.01 to 80 mm.sup.2/s at 40° C., a water holding percentage of 0.01 to 4.0 mass %, and a weight-average molecular weight of less than 1,000, on at least the projection in an excretory opening contact region.

An absorbent article has a top sheet, a back sheet, and an absorbent assembly positioned between the back sheet and the top sheet. The absorbent article includes a fluid intake layer positioned between the absorbent assembly and the top sheet. The fluid intake layer has a rearward-facing arch located in a back portion of the fluid intake layer. The fluid intake layer has an opening. The absorbent article includes a first lateral stiffener and a second lateral stiffener extending along a majority of the longitudinal side edges of the fluid intake layer. The absorbent article includes a first flexure, a second flexure, and a third flexure in a rear portion of the absorbent article.

An odor and menses absorption device includes a user contact layer and at least one adjoining super absorbent core layer. Fluid can move from the user contact layer to the super absorbent core layer. The user contact layer contains a blend of polylactic acid fiber and bamboo charcoal fiber and acts as a barrier to fluids with a surface tension greater than 30 dynes.

An absorbent article includes a body side liner, a back sheet, an absorbent body positioned between the body side liner and the back sheet, and a distribution layer positioned between the absorbent body and the back sheet. The absorbent body defines a first opening having an opening length that is at least 50% the absorbent body length. The first opening has a median anterior portion width that is greater than a median central portion width that is greater than a median posterior portion width. The first opening includes a well, a channel, and a taper. The well transitions into the channel via a first convex transition and a concave transition. The channel transitions into the taper via a second convex transition.

An absorbent article includes a body and a hip holding portion. The body has a shape having a predetermined length in a front-rear direction and a predetermined width in a direction perpendicular to the front-rear direction. The hip holding portion includes a side region protruding from a rear side portion of the body and a rear region protruding from the rear end of the body, and includes a first protruding portion including a portion where the width of the body from a centerline in the front-rear direction is largest, a first depressed portion forward of and adjacent to the first protruding portion, and a second protruding portion forward of and adjacent to the first depressed portion in the side region. The width of the second protruding portion from the centerline is smaller than or equal to the smallest width of the first depressed portion from the centerline.
