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.

The present disclosure is directed, in part, to an absorbent article comprising a topsheet, a backsheet and absorbent core positioned at least partially intermediate the topsheet and the backsheet. The absorbent core comprises an absorbent material positioned within a core wrap. The absorbent core defines a first channel therein. A material is positioned at least partially intermediate the topsheet and the core wrap. The material defines a second channel therein.

An absorbent article (20) having an absorbent core comprising at least about 80% of superabsorbent polymers (SAP) by weight of its absorbent material. An acquisition-distribution system (ADS) (50) is at least partially disposed between the absorbent core and the topsheet. The ADS extends in the longitudinal direction of the absorbent article at least from a point A1 disposed at a distance D from the front edge to a point A2 disposed at a distance D from the back edge of the article, D being equal to 32% of the length L of the article. The ADS has a basis weight which may be at least 20% lower at the point A2 than at the point A1.

An absorbent article includes a polymer sheet (4) where a superabsorbent polymer (12) is disposed between an upper layer sheet (10) disposed on a skin side and a lower layer sheet (11) disposed on a non-skin side. The diffusion area of the lower layer sheet (11) is 1500 mm.sup.2 or greater. The diffusion area is measured by an absorption test method including: (1) preparing a specimen with a size of 100 mm100 mm, (2) placing a tip of a buret at a height of 10 mm above a surface of the specimen, and dropping one droplet of ion-exchanged water from the buret, and (3) after 3 minutes from a time when the droplet reaches the surface of the specimen, measuring, as the diffusion area, an area of a region of the surface of the specimen where a reflection from water is clearly visible.

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.
