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.

Carded nonwoven fibrous web and use in absorbent articles

A carded nonwoven fibrous web and method of making is provided. The web comprises at least 50%, by weight of the fibrous web, of staple fibers and at least 10%, by weight of the fibrous web, of non-fibrous latex binder, wherein, the staple fibers are autogenously bonded to each other and are bonded to each other by the latex binder.

Super absorbing composite material, form factors created therefrom, and methods of production

Super absorbent material used for drying that integrates super absorbent non-woven fibrous mats with other material, as for example wicking material, are described. The fibrous mats consist of polymeric material embedded with particles of super absorbent polymer. The wicking material may be lightweight knitted fabric that actively absorbs and wicks liquid across the fabric surface. The materials are fabricated as single layer or multiple layers and demonstrate a variety of form factors suitable to the intended use. The super absorbent materials may incorporate additional functionalities, such as antifungal or antibacterial, for biomedical uses.

ABSORBENT PAD

To provide an absorbent pad, the absorbent pad being formed of an inner absorbent pad which is positioned on the body-side and an outer absorbent pad positioned on the non-body side, wherein when the inner absorbent pad absorbs liquid excretions and swells, openings are provided at the side which is indented furthest towards the non-body side, improving the passage of liquid, and improving the dispersion of sites facing the openings in the outside absorbent pad, preventing leakage of liquid excretions to the exterior.

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 superabsorbent polymer. 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.

Fibrous Web and Surge Layer Made from Same
20240050291 · 2024-02-15 ·

Nonwoven webs having excellent fluid handling characteristics are disclosed. The nonwoven webs are made from a combination of binder fibers and structure fibers. The nonwoven webs can be made exclusively from polyolefin polymers without having to contain polyester fibers. Although the webs can be used in numerous applications, the nonwoven materials are particularly well suited as a surge layer in an absorbent article.

Absorbent article with cushion layer defining air pockets

Disposable absorbent articles and methods of making disposable absorbent articles that comprise: an absorbent structure; and a layer of cushion material configured to minimize user perception of hardness or hard spots in the absorbent structure.
