Absorbent article and absorbent core forming channels when wet

An absorbent article for personal hygiene comprising a liquid permeable topsheet, a liquid impermeable backsheet, an absorbent core and a fibrous layer. The absorbent core comprises a core wrap and an absorbent material with superabsorbent polymers. The core wrap comprises a top side and a bottom side bonded to one other through one or more areas substantially free of absorbent material. The fibrous layer is at least partially bonded to one of the sides of the core wrap in the area substantially free of absorbent material. When the absorbent material swells, the core wrap forms one or more channels along the area substantially free of absorbent material. The formation of the channel in the absorbent core causes the formation of one or more corresponding ditches in the fibrous layer.

ABSORBENT ARTICLES WITH CHANNELS AND SIGNALS

Absorbent articles herein may provide a topsheet, a backsheet, an absorbent core disposed between the topsheet and the backsheet. The absorbent core may comprise at least one channel having a shape. The backsheet graphics may substantially match the shape.

A plurality of openings (11) is formed in a region corresponding to at least a body fluid discharge region (H) of a liquid permeable top sheet (3). A polymer sheet (6) disposed adjacent to a surface of an absorbent body (4) side of the liquid permeable top sheet (3) is included, and the polymer sheet includes highly absorbent resin disposed along a longitudinal direction on both sides of the region corresponding to the body fluid discharge region (H). Upon the highly absorbent resin becoming swollen by absorption, a space (10) for holding a body fluid is formed between regions in which the highly absorbent resin is disposed (12) and also between the liquid permeable top sheet (3) and the polymer sheet (6).

Absorbent article with a lotioned topsheet

An absorbent article having a longitudinal axis extending in a longitudinal direction and a transversal axis extending in a transversal direction perpendicular to the longitudinal direction. The absorbent article comprises a fluid-permeable topsheet, a lotion on the topsheet having a lotion pattern covering a lotion pattern area, a fluid-impermeable backsheet, and an absorbent core between the topsheet and the backsheet. The core wrap defines a core footprint in a plane parallel to the longitudinal direction and transversal direction. The ratio of the lotion pattern area relative to the area of the footprint of the absorbent core ranges from 5% to 25%.

Absorbent article with a lotioned topsheet

An absorbent article having a longitudinal axis extending in a longitudinal direction and a transversal axis extending in a transversal direction perpendicular to the longitudinal direction. The absorbent article comprises a fluid-permeable topsheet, a lotion on the topsheet having a lotion pattern covering a lotion pattern area, a fluid-impermeable backsheet, and an absorbent core between the topsheet and the backsheet. The core wrap defines a core footprint in a plane parallel to the longitudinal direction and transversal direction. The article comprises an intermediate layer between the topsheet and the absorbent core, the intermediate layer comprising at least one longitudinally-extending channel, preferably at least a pair of longitudinally-extending channels disposed symmetrically on each side of the longitudinal axis. The topsheet is depressed in the channel(s). The lotion-to-channel overlap ratio ranges from 0% to 20% of the area of the channel(s). The lotion-to-channel overlap ratio is the percentage of the channel(s) of the intermediate layer overlapping with the lotion pattern.

ABSORBENT ARTICLE WITH BODY CONFORMING STRUCTURE

An absorbent article (10) is disclosed. The absorbent article (10) can have a topsheet layer (30), a liquid impermeable layer (36), and an absorbent assembly (40) positioned between the topsheet layer (30) and the liquid impermeable layer (36). The absorbent assembly (40) can have a body conforming layer (38) which has a plurality of slits (50) and at least one crease (60) extending in the longitudinal direction (X). The presence of the plurality of slits (50) and the crease (60) in the body conforming layer (38) can provide for a reduction in the stiffness of the absorbent assembly (40). The absorbent article (10) can deform under pressure and have an improvement in conformity to the body of the wearer of the absorbent article (10).

ABSORBENT ARTICLE WITH HIGH ABSORBENT MATERIAL CONTENT

An absorbent article includes a longitudinal axis extending in a longitudinal direction of the article, a liquid permeable topsheet, a liquid impermeable backsheet, and an absorbent core disposed between the topsheet and backsheet. The absorbent core includes a combination of superabsorbent polymer and cellulose fibers. The article further includes an acquisition-distribution layer; and at least one channel positioned within a layer located between the topsheet and the backsheet, the at least one channel being substantially free of fibers and superabsorbent polymer. An indentation occurs in at least one of the topsheet and the backsheet that correspond to the at least one channels when the article is loaded with fluid.

A core press depressed toward a back-side sheet is formed on at least a surface of an absorber facing an upper-side sheet such that the thickness of the absorber is reduced in the thickness direction, right and left compressed grooves are formed along the longitudinal direction of a sanitary napkin on at least the sides of an area corresponding to a body fluid discharge part of a wearer, and a high absorption part having a greater absorption capacity per unit area than other parts is formed at least between the right and left compressed grooves of the absorber.

FLEXIBLE AND COMPLIANT MECHANICALLY-DEFORMED NONWOVENS FOR USE IN ABSORBENT ARTICLES

A mechanically deformed nonwoven comprising a plurality of protrusions extending outwardly from a first surface of the nonwoven and having openings c corresponding to the protrusions in a second surface of the nonwoven. The nonwoven has a Horizontal Bending Drop at 100 mm of at least 75 mm and a Z-Compliance Index of at least 50 mm.sup.3/N. The nonwoven can be used in absorbent articles such as diapers as an acquisition layer between the absorbent core and the backsheet and/or as a masking layer between an absorbent layer core and the backsheet.
