Fluid-absorbent article

A fluid-absorbent article having an upper liquid-pervious layer, a lower liquid-impervious layer, a fluid-absorbent core between the layer and the layer, containing from 0 to 20% by weight fibrous material and from 80 to 100% by weight of a water-absorbent polymer material, based on the sum of water-absorbent polymer material and fibrous material. The fluid absorbent article has a first intake time of 15 seconds or less by the hanging U-shape test (HUS).

Method of making an absorbent composite and absorbent articles employing the same

A method of making an absorbent composite that includes a first fabric, a second fabric, and particles positioned between the two fabrics and absorbent articles made from the absorbent composite. The particles are secured between the two fabric using adhesive, thermal plastic or combinations thereof. The fabrics are bonded together in a manner that limits particle movement between the fabrics. The bond pattern may define pockets or other shapes. In applications in which the bond pattern forms pockets, the particles may be positioned in the pockets. The particles may be SAP particles or other particles with advantageous properties.

This disclosure makes it possible to form embossments with good appearance even when a polymer sheet is used as an absorber and makes it possible to reliably implement the function of the embossments. A sanitary napkin (1) includes a polymer sheet (4) including a superabsorbent polymer (12) disposed between an upper-layer sheet (10) disposed on a skin side and a lower-layer sheet (11) disposed on a non-skin side, and an embossment (20) that is formed on a skin-side surface of the polymer sheet (4) along a longitudinal direction of the sanitary napkin (1) and is shaped like a discontinuous line formed by arranging compressed parts (21) and non-compressed parts (22) alternately. The ratio A:B of a length (A) of each of the compressed parts (21) to a length (B) of each of the non-compressed parts (22) is between 7:1 and 1:1.

Absorbent articles having channel-forming areas and wetness indicator
10828206 · 2020-11-10 · ·

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.

Absorbent composite including swellable absorbent fibers

Generally, an absorbent composite comprising between about 20% and about 80% by weight of the particulate superabsorbent material and between about 20% and 80% by weight of a swellable absorbent fiber is disclosed herein. The swellable absorbent fiber is substantially water-insoluble and water-swellable and a centrifuge retention capacity of between 5 and 20 grams per gram after four hours and reaches at least 66% of centrifuge retention capacity between about 2 and about 50 seconds.

ABSORBENT ARTICLES WITH CHANNELS

The present disclosure is directed, in part, to an absorbent article comprising a liquid management system (LMS) and an absorbent core disposed at least partially intermediate a topsheet and a backsheet. The LMS defines one or more channels therein. The one or more channels of the LMS may at least partially overlap or not overlap with channels defined in the absorbent core.

PROCESS FOR MAKING AN ABSORBENT ARTICLE COMPRISING A TOPSHEET/ACQUISITION LAYER LAMINATE

A process of making an absorbent article is disclosed. A liquid permeable topsheet web extending substantially continuously in a machine direction a backsheet web, and an intermediate layer are provided. The topsheet web has first and second surfaces. The backsheet web extends substantially continuously in the machine direction. The intermediate layer has a first and second surface. The topsheet and intermediate layer are aligned in a face to face relationship such that the second surface of the topsheet in in contact with the first surface of the intermediate layer and simultaneously mechanically deformed which combines the topsheet with the intermediate layer. The topsheet web and intermediate layer are nested together such that a majority of the three-dimensional protrusions formed in the topsheet web coincide with and fit together with a majority of the three-dimensional protrusions formed in the intermediate layer to provide a topsheet/intermediate layer laminate web having three-dimensional protrusions.

Absorbent article with profiled acquisition-distribution system

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.
