An absorbent article comprising a liquid pervious topsheet (300), a liquid impervious backsheet (200), absorbent material positioned between the liquid pervious topsheet and the liquid impervious backsheet, and a capillary acceleration sheet (400) between the absorbent material and the liquid pervious topsheet, wherein the absorbent material is arranged on a bottom core wrap sheet such that one or more channels are formed, wherein less absorbent material per surface area is present in the one or more channels compared to an area around the one or more channels, wherein preferably substantially no absorbent material is present in the one or more channels, wherein the capillary acceleration sheet (400) has a basis weight between 15 and 55 g/m2 and comprises fibres having an average diameter between 10 and 35 micron, preferably between 15 and 30 micron, more preferably between 17 and 27 micron.

An absorbent sanitary article includes a fluff absorbent core having at least one through aperture, a fluff-free absorbent core, and an acquisition and diffusion layer set between the fluff absorbent core and the fluff-free absorbent core and overlapping the at least one through aperture.

The presently disclosed subject matter relates to multi-layer nonwoven materials and their use in absorbent articles. More particularly, the presently disclosed subject matter relates to layered structures that have high absorbency performance while having less absorbent mass than other commercially available materials.

A urine absorption pad for preventing leakage of urine is provided. A urine absorption pad includes: a front surface sheet (16) which has water permeability and contacts a skin; a back surface sheet (17) which has water impermeability and contacts underwear; an absorbent (18) which is sandwiched between the front surface sheet (16) and the back surface sheet (17) and absorbs urine having passed through the front surface sheet (16); and a guide A (11) and a guide B (12) which allow urine to permeate and are self-standing so as to rise to the front surface sheet (16) side with respect to the absorbent (18) to control flow of urine. The guide A (11) is arranged at an edge portion, and the guide B (12) is arranged so as to extend in a left-right direction.

The presently disclosed subject matter relates to multi-layer nonwoven materials and their use in absorbent articles, e.g., as absorbent cores and/or acquisition distribution layers (ADL). More particularly, the presently disclosed subject matter relates to layered structures that provide for improved liquid acquisition, distribution, storage and rewet properties while allowing for the use of less synthetic materials, such as superabsorbent polymers (SAP) than other commercially available materials.

A disposable absorbent article may include a chassis that includes a topsheet, a backsheet, and an absorbent core disposed between the topsheet and the backsheet; and a leg gasketing system. The leg gasketing system may include an inner cuff and an outer cuff; the inner cuff may include an inner cuff folded edge and an inner cuff material edge and the outer cuff may include an outer cuff folded edge and an outer cuff material edge such that the web of material is folded laterally inward to form the outer cuff folded edge and folded laterally outward to form the inner cuff folded edge, and the leg gasketing system further including a leg gasketing system pocket with an opening on an inboard longitudinal edge of the leg gasketing system pocket. The disposable absorbent article also includes at least one channel in the absorbent core.

An absorbent article such as a diaper extending in a longitudinal direction parallel to a longitudinal axis (80′) and a transversal direction (90′) perpendicular to the longitudinal direction and comprising a distribution layer (54) between a topsheet (24) and an absorbent core (28). The distribution layer comprises a fibrous material and a first and second longitudinally-extending channels (86a,b) substantially free of fibrous material. The fibrous material is profiled in the transversal direction so that average basis weight between the channels differs from the average basis weight in the lateral areas outward of the channels by at least 50 g/m.sup.2 and/or wherein the distribution layer comprises a first region having a first basis weight (bw1) and a second region having a second basis weight (bw2), wherein the first basis weight and the second basis weight differ by at least 20 g/m.sup.2, preferably by at least 50 g/m.sup.2, and these regions are present in different areas of the distribution layer but in the same longitudinally extending transversal section. The absorbent core may comprise channel-forming areas (26a,b). The article further comprises a backsheet (25).

Methods and apparatuses for producing a zoned and/or layered substrate are described. A substrate can include a first layer including a first zone, a second zone, and an interface between zones. The first zone can include a plurality of fibers. The second zone can include a plurality of fibers and can be offset from the first zone in a cross-direction. The interface can include at least some of the plurality of fibers of the first zone and at least some of the plurality of fibers of the second zone to provide a purity gradient with a transition width less than 3.8 cm as defined by the Purity Gradient Test Method as described herein.

Methods and apparatuses for producing a zoned and/or layered substrate are described. A method can include providing a first supply of fibers, providing a second supply of fibers, and providing a headbox. The headbox can include a machine direction, a cross-direction, and a first cross-directional divider that separates a first zone of the headbox from a second zone of the headbox in a cross-directional manner. The method can further include transferring the first supply of fibers and the second supply of fibers to the headbox. The method can also include transferring the first supply of fibers and the second supply of fibers through the headbox to provide the substrate.
