Absorbent article with an exudate management layer

An absorbent article can have a topsheet layer, a liquid impermeable layer, and an absorbent core positioned between the topsheet layer and the liquid impermeable layer. The absorbent article can further include an exudate management layer in fluid communication with the topsheet layer. In various embodiments, the exudate management layer can be positioned on a body facing surface of the topsheet layer. In various embodiments, the exudate management layer can be positioned between the topsheet layer and the absorbent core. The exudate management layer has a first component which defines an opening for direct passage of body exudates into the absorbent core. The exudate management layer has a second component which at least partially overlaps the first component of the exudate management layer and further extends in the longitudinal direction of the absorbent article in a direction towards the posterior region of the absorbent article.

Method of manufacturing an activated composite web and an activated composite web for absorptive devices

A method of manufacturing an activated composite web includes laminating a film layer to a nonwoven web to form a composite web, forming a plurality of apertured protuberances in the film layer, and passing the composite web through intermeshing elements to form an activated composite web. The intermeshing elements form a plurality of first lanes, with first widths, substantially unaffected by activation, and a plurality of second lanes, with second widths. The second widths are less than the first widths. Portions of the plurality of apertured protuberances define first apertures in the first lanes and second apertures in the second lanes. The cross-sections of the second apertures are larger than the first apertures. The first apertures have their major axes substantially aligned in the first direction while the second apertures have their major axis substantially aligned in the second direction. An activated composite web also is provided.

Absorbent articles forming a three-dimensional basin

An absorbent article such as a diaper comprises a topsheet, a backsheet and an absorbent core. The absorbent layer comprises at least a longitudinally-extending central portion, and a first and second side portions disposed transversally outward of the central portion. The absorbent core further comprises first and second folding guides between the central portion and the side portions. Each side portion comprises a plurality of winglets, each winglet having a proximal side relative to a folding guide and extending outward from this proximal side, and wherein neighboring winglets are separated by a gap between their neighboring sides. The central portion and the side portions form a three-dimensional basin when the absorbent core is folded along the folding guides. The article further may comprise at least one liquid management layer substantially free of superabsorbent polymer between the topsheet and the absorbent core. The absorbent core may be substantially free of cellulose fibers.
