Absorbent articles having channel-forming areas and wetness indicator
12226292 · 2025-02-18 · ·

An absorbent article comprising an absorbent core having a longitudinally extending channel-forming area and a wetness indicator. The core wrap comprises a top side and a bottom side, which are attached to each other through areas substantially free of absorbent material, so that when the absorbent material swells upon absorption of a liquid a channel is formed along the area substantially free of absorbent material.

Expandable absorbent core and method of manufacture

An expandable absorbent structure comprises an expansion loop core configured to expand in response to absorption of a liquid and an expansion loop material structure surrounding the expansion loop core and having a trough therein, wherein the trough is formed from a first portion of the expansion loop material structure folded over a second portion of the expansion loop material structure at a first elbow of the expansion loop material structure. In response to an increase in size of the expansion loop core, the expansion loop core presses against the expansion loop material structure to cause a length of the trough to decrease.

ABSORBENT CORES HAVING MATERIAL FREE AREAS
20170135870 · 2017-05-18 ·

An absorbent core for use in an absorbent article is provided and comprises a core wrap enclosing an absorbent material, the absorbent material comprising superabsorbent polymer particles. The core wrap comprises a top side and a bottom side. The absorbent core comprises one or more area(s) substantially free of absorbent material through which the top side of the core wrap is attached to the bottom side of the core wrap (i.e. core wrap bond(s)), so that when the absorbent material swells, the core wrap forms one or more channel(s) along the area(s) substantially free of absorbent material. The superabsorbent polymer particles have a value of Effective Capacity (EFFC) of at least 27 g/g. The Effective Capacity (EFFC) is calculated via the formula below: EFFC=(CRC+AAP)/2. The Centrifuge Retention Capacity (CRC) is measured according to the Centrifuge Retention Capacity (CRC) test method and the Absorption Against Pressure (AAP) is measured according to the Absorption Against Pressure (AAP) test method. The superabsorbent polymer particles have a bulk density of at least 0.5 g/ml according to the Bulk Density Test Method.

An absorbent article, including a liquid permeable top sheet, a pulpless absorbent core, the core including synthetic fibers and a super absorbent material, the super absorbent material being settled and stabilized by an open formation bottom high loft layer with fibers oriented in a Z direction, and a liquid impermeable backsheet, wherein the absorbent core is positioned between the top sheet and the backsheet.

ABSORBENT ARTICLES WITH IMPROVED CORE

An absorbent article including a wearer-facing topsheet, a backsheet and an absorbent core disposed between the topsheet and the backsheet, characterized in that the absorbent core includes: a first absorbent layer comprising a first substrate, a layer of first superabsorbent polymer particles deposited on the first substrate, and a fibrous layer of thermoplastic adhesive material covering the layer of first superabsorbent polymer particles; a second absorbent layer, the second absorbent layer comprising a second substrate and a mixed layer deposited on the second substrate, the mixed layer comprising a mixture of second superabsorbent particles and cellulosic fibers, the first absorbent layer and the second absorbent layer being combined together such that at least a portion of the fibrous layer of thermoplastic adhesive material of the first absorbent layer contacts at least a portion of the mixed layer of the second absorbent layer, and wherein the first absorbent layer is placed closer to the topsheet than the second layer.

ABSORBENT ARTICLES HAVING CHANNELS, STRETCHABLE WAISTBANDS AND BACK EARS

An absorbent article includes a topsheet, a backsheet, an absorbent core and at least one longitudinally-extending channel that is substantially free of absorbent material. The article further includes a stretchable back waistband extending transversally adjacent the back edge of the article and a pair of stretchable back ears. The back ears each include a fastening tab that can be releasably engaged with a landing zone on the garment-facing side of the article.

ABSORBENT ARTICLES HAVING CURVED CHANNELS

An absorbent article, such as a diaper or a training pant, having a wearer-facing side and a garment-facing side and a longitudinal axis, includes an absorbent core with at least two longitudinally extending curved channels and an air-through bonded carded nonwoven layer as topsheet or acquisition layer under the topsheet.

Absorbent article with main and auxiliary absorption layers
12239517 · 2025-03-04 · ·

An absorbent article in which an absorber includes an upper auxiliary layer disposed on an uppermost portion and a main absorption layer disposed on a back surface side of the upper auxiliary layer, and the upper auxiliary layer includes a super absorbent nonwoven fabric having a surface exposed to an uppermost surface of the absorber and having a Klemm water absorptiveness of 100 mm or more.

ABSORBENT ARTICLE COMPRISING A THREE-DIMENSIONAL SUBSTRATE

An absorbent article for personal hygiene comprises a three-dimensional substrate, a tissue layer, an absorbent core and a backsheet. The absorbent core is located at least partially between the three-dimensional substrate and the backsheet. The tissue layer is located at least partially between the three-dimensional substrate and the absorbent core. The tissue layer comprises a wet-laid three-dimensional fibrous substrate comprising at least 80% pulp fibers by weight of the wet-laid three-dimensional fibrous substrate. The wet-laid three-dimensional fibrous substrate comprises a continuous network region and a plurality of discrete zones.
