An absorbent article comprising a liquid pervious topsheet, a liquid impervious backsheet, and an absorbent core comprising an absorbent material between a top core wrap sheet and a back core wrap sheet, said absorbent core being positioned in between said topsheet and said backsheet, said absorbent core having a first and second side edge, a front edge and a rear edge, wherein the absorbent core is provided with a plurality of attachment zones where the top core wrap sheet is attached to the back core wrap sheet, and where substantially no absorbent material is present, wherein, seen in a longitudinal direction of the absorbent core, looking from the front edge to the rear edge, the absorbent core comprises subsequently a first, second, third, fourth and fifth zone.

An absorbent article comprising a liquid pervious topsheet, a liquid impervious backsheet, and an absorbent core comprising an absorbent material between a top core wrap sheet and a back core wrap sheet, said absorbent core being positioned in between said topsheet and said backsheet, said absorbent core having a first and second longitudinal edge and a first and second transverse edge, said absorbent core having a first portion (130a), (130b) and a second portion (130b), (130a) on either side of a transverse crotch line (L), wherein the absorbent core is provided with a plurality of attachment zones where the top core wrap sheet is attached to the back core wrap sheet, wherein, measured in a transverse direction, a first maximum distance between a first and a second attachment zone is bigger than a second maximum distance between a third and a fourth attachment zone.

An absorbent article according to the present invention may comprise an absorbent pad 12, which includes: a wood pulp web 12b and a cotton-based nonwoven fabric 12a laminated on the wood pulp web 12b, wherein the nonwoven fabric 12a includes a valley part continuously formed on a surface thereof in a length direction and arranged at a predetermined interval in a width direction thereof. The absorbent article manufactured according to the present invention includes the absorbent pad layer 12 consisting of the cotton-based nonwoven fabric 12a, wherein the nonwoven fabric 12a includes the valley part continuously formed in the length direction and arranged at a predetermined interval in the width direction on the surface of the nonwoven fabric 12a in order to form channels C in the length direction of the absorbent pad 12, thereby effectively preventing leakage of the menstrual fluid or urine. Further, the absorbent article according to the present invention includes the wood pulp web 12b as well as the cotton-based nonwoven fabric 12a in the absorbent pad 12, thus to rapidly absorb the menstrual fluid or urine and safely keep the same therein.

A flexible absorbent pad has a dry thickness of between 2 mm and 10 mm and a difference in flexural-resistance between the dry state and the wet state of an absorbent center zone of the absorbent pad of less than 100 grams-force. The absorbent core of the pad may include an airlaid, a foam, or a fibrous staple filament. The absorbent core of the absorbent pad may be corrugated, such as with flexure hinges, in which case adhesive is applied to the backsheet of the absorbent pad in a pattern that leaves the flexure hinges devoid of adhesive so that the backsheet is attached to the absorbent core in a manner that does not impede the flexing of the flexure hinges.

Disposable absorbent articles suitable for providing bladder leakage cessation for females that experience urinary incontinence may comprise a primary sheet, a secondary sheet, and an absorbent sheet disposed between the primary and secondary sheet. The four-sided primary and secondary sheets each may include four edges, whereby each edge having a selvedge. The absorbent sheet may further include a plurality of macrofolds folded in a counter direction to the primary sheet length and the secondary sheet length. The selvedge edges of the primary sheet and the secondary sheet may couple together around the absorbent sheet to form a pillow package. With the proper placement of the pillow package, bladder leakage can be stopped and mitigated. The article can exhibit an article length and width from about 38 mm to about 50 mm.

The present disclosure is directed, in part, to absorbent article comprising a liquid permeable topsheet, a liquid impermeable backsheet, a lateral axis defining a front region on a first side of the lateral axis and a back region on a second side of the lateral axis, and an absorbent core positioned at least partially intermediate the liquid permeable topsheet and the liquid impermeable backsheet. The liquid permeable topsheet may comprise a first zone situated primarily in the front region and having a substantially transferrable chemical treatment and a second zone situated primarily in the back region and having the substantially transferrable chemical treatment. A basis weight of the substantially transferrable chemical treatment may be greater in the second zone than in the first zone.

Disposable absorbent articles comprising absorbent cores are presented. In one embodiment, an absorbent core may comprise a riffled substrate comprising a plurality of peaks and a plurality of troughs, a flat substrate coupled to the riffled substrate, and superabsorbent polymer disposed between the riffled substrate and the flat substrate, wherein the footprint of the riffled substrate is substantially the same as the footprint of the flat substrate, and wherein the surface area of the riffled substrate is greater than the surface area of the flat substrate.

A polymer provided region (13) at which a superabsorbent polymer (12) is provided, and a polymer non-provided region (14) at which the superabsorbent polymer (12) is not provided are formed, a liquid diffusion sheet (15), that promotes diffusion of body fluid in a plane direction, is staked to be adjacent to a skin side surface of a lower layer sheet (11), and an upper layer sheet (10) is bonded with the liquid diffusion sheet (15) under a state that the upper layer sheet (10) contacts the liquid diffusion sheet (15), at the polymer non-provided region (14) to form a polymer sheet (4).
