An absorbent article includes: a sheet-type leakage-preventing body; absorbent body, at least one layer arranged on the leakage-preventing body top, which absorb fluids; pair of left and right floating leg gathers on the absorbent body top, extending in longitudinal direction from the main body front end of the absorbent article to the rear end, traversing a front body section, crotch part, and rear body section. Each floating leg gathers have a top and trailing parts adjoining the top part. Front and rear ends of the floating leg gathers are joined respectively to the vicinity of the front and rear end of the absorbent article main body. Trailing parts trail downwards from top parts towards the absorbent body. At least one part of the trailing parts of the left and right floating leg gathers is mutually connected in the lower end area forming a channel for bodily fluids inside trailing parts.

The absorbent article as disclosed herein has longitudinal side edges extending in a longitudinal direction and transverse front and rear end edges extending in a transverse direction. The absorbent article comprises a fluid permeable surface layer, a backsheet and an intermediate layer located between the fluid permeable surface layer and the backsheet. The surface layer has a wearer-facing portion facing the user during use. The surface layer is an air through bonded fibrous nonwoven surface layer having a basis weight of from 14 to 30 g/m2 and a density of from 20 to 90 kg/m3. The intermediate layer extends under from 70 to 100% of the wearer-facing portion of the surface layer. The intermediate layer and the surface layer have a respective elongation at 10 N/50 mm. The elongation of the intermediate layer is lower than the elongation of the surface layer.

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.

The present invention relates to an absorbent core of an absorbent product including a liquid-permeable top sheet, an absorbent dispersion layer disposed at a lower portion of the top sheet, an absorbent core disposed at a lower portion of the absorbent dispersion layer and absorbing and retaining liquids, and a liquid-impermeable back sheet disposed at a lower portion of the absorbent core, and the absorbent core has effects of having the convenience of storage and the activity when an absorbent product prepared therefrom is worn by a user and improving liquid permeability compared to an existing absorbent core.

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 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.

The invention includes a hot melt adhesive composition including an olefin polymer and a high melt point hydrocarbon tackifying agent, such compositions unexpectedly provide improved bonding between the layers found in a disposable absorbent article. In particular, such compositions improve the bond between the nonwoven top sheet and the acquisition distribution layer.

A nonwoven fabric is provided. The nonwoven fabric can include a first surface and a second surface and a visually discernible pattern of three-dimensional features on one of the first or second surface. Each of the three-dimensional features can define a microzone comprising a first region and a second region. The first and second regions can have a difference in values for an intensive property, wherein at least one of the surfaces has a TS7 value of less than about 15 dB V.sup.2 rms, and wherein the first surface has a TS7 value that is higher than the second surface TS7 value.
