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.

The absorbent system can have at least a fluid intake layer, an absorbent core, and a distribution layer. The fluid intake layer can define a fluid intake layer opening and the absorbent core can define an absorbent core opening. A void space is present between the top sheet layer and the distribution layer and the top sheet layer is maintained in a spaced apart relationship from the distribution layer.
ABSORBENT ARTICLE CONTAINING NANOPOROUS SUPERABSORBENT PARTICLES
An absorbent article includes an absorbent member positioned between a topsheet and a backsheet. The absorbent member contains at least one layer that includes superabsorbent particles containing a porous network that includes a plurality of nanopores having an average cross-sectional dimension of from about 10 to about 500 nanometers, wherein the superabsorbent particles exhibit a Vortex Time of about 80 seconds or less and a free swell gel bed permeability (GBP) of 5 darcys or more, of 10 darcys or more, of 60 darcys or more, or of 90 darcys or more.
ABSORBENT ARTICLE
An absorbent article which can have an improved feeling of comfort next to the skin of the wearer and a reduction in the feelings of wetness and rewet. An absorbent article can have a longitudinal direction, a transverse direction, and a depth direction. The absorbent article can have a topsheet layer, a backsheet layer, and an absorbent core positioned between the topsheet layer and the backsheet layer. The topsheet layer can have a hydrophilic central layer, a semi-hydrophilic first side layer, and a semi-hydrophilic second side layer. Each of the semi-hydrophilic side layers can be bonded to the central layer utilizing an embossing technique in the regions of overlap of each of the semi-hydrophilic side layers with the central layer. The area of the body-facing surface of each of the regions of overlap can contain from about 10% to about 35% of at least one embossment.
Fluid distribution material for absorbent articles
A fluid distribution material for use in an absorbent article includes a formed film layer having a user-facing side and a garment-facing side opposite the user-facing side. The formed film layer includes a plurality of apertured protuberances arranged in a pattern having 10 to 40 protuberances per linear inch. Each of the protuberances includes a continuous sidewall extending from the user-facing side. The garment-facing side has a plurality of apertures aligned with the plurality of apertured protuberances and land areas in between the apertures. A nonwoven layer is laminated to the garment-facing side of the formed film layer. The nonwoven layer includes a plurality of continuous fibers extending across the land areas and the plurality of apertures of the formed film layer and attached to the land areas at bond sites. The fluid distribution material has a compressibility of less than 10% between pressures of 0.21 psi and 0.60 psi.
FLUID MANAGEMENT LAYER FOR AN ABSORBENT ARTICLE, AND AN ABSORBENT ARTICLE CONTAINING THE SAME
The present invention relates to a nonwoven sheet from about 10% to about 60% of non-swelling wicking fibers, from about 15% to about 70% of resilient fibers, and from about 25% to about 70% of stiffening fibers by weight of fluid the nonwoven as determined by the Material Composition Analysis, and wherein the non-swelling wicking fibers have a relative shape factor in radius in the range of about 25% to about 100% as determined the Relative Shape Factor in Radius test, and have a linear density of 0.8 dtex to 3.3 dtex as determined the Fiber Decitex test; and an absorbent article comprising a liquid permeable topsheet, a liquid impermeable backsheet, an absorbent core disposed between the topsheet and the backsheet, and a fluid management layer disposed between the topsheet and the absorbent core, the fluid management layer comprising the nonwoven sheet disclose herein.
Absorbent structure with stratified distribution layer
