20220096285 · 2022-03-31 ·

An absorbent core comprising substantially continuous zones of one or more high fluid distribution structures and discontinuous zones of fluid absorption structures surrounding the one or more high fluid distribution structures, wherein the one or more high fluid distribution structures are arranged to distribute fluid across the absorbent core at a speed that is faster than the speed of fluid distribution across the absorbent core by said discontinuous fluid absorption structures, and wherein said continuous zones extend along a path that is substantially parallel to at least a portion of the perimeter of the core, said portion of the perimeter of the core comprising at least a portion of the sides of the core and one of the ends of the core.

Perineal thermal pack with improved liquid containment

Devices for providing thermal therapy to the perineal and rectal areas of a patient are described. The device is particularly useful for containing gushing lochia flow. Different embodiments of the device can be used to provide either hot or cold therapy to the patient. The inventive thermal pack of the current invention comprises a thermal pouch, pad and a backing layer.

Topsheet comprising natural fibers with good mechanical strength

A topsheet for use with an absorbent article is provided and comprises a first layer and a second layer. The first layer is a spunlace nonwoven and comprises at least 15% by weight of natural fibers by total weight of the first layer. The first layer comprises a plurality of protrusions and a plurality of apertures. The first layer and the second layer are in contact with each other between the plurality of the protrusions. The second layer has a plurality of apertures at least partially aligned with the apertures of the first layer. The first layer has a minimum CD strength of at least 3N/(5 cm), according to the Tensile Strength Test Method.

A liquid permeable surface sheet (3) includes an upper layer non-woven fabric (20) which is provided at the skin side, and which is hydrophilic, and a lower layer non-woven fabric (21) which is provided at the non-skin side, and which is water repellent. Multiple apertures (22) are formed which penetrate the upper layer non-woven fabric and the lower layer non-woven fabric. Accordingly, body fluid transfers smoothly through the apertures to an absorbent body. The upper layer non-woven fabric at the skin side is made to be hydrophilic such that body fluid readily permeates therethrough. The lower layer non-woven fabric at the non-skin side is made to be water repellent such that the body fluid which has passed through is not readily absorbed again. Accordingly, the backflow amount of body fluid can be reduced.

Olefin Block Copolymer-based Hot Melt Adhesive Composition
20220073790 · 2022-03-10 ·

The present invention provides a hotmelt adhesive composition, comprising: (A) an olefin block copolymer of ethylene and octene, having a melt index of 10 to 35 g/10 min @ 190° C., 2.16 kg, preferably 15 to 30 g/10 min @ 190° C., 2.16 kg, and (B) a wax modified with carboxylic acid and/or carboxylic acid anhydride.

DISPOSABLE ABSORBENT ARTICLE

A disposable absorbent article is provided having an absorbent core located in a chassis and including absorbent particulate polymer material defining at least one cavity. The absorbent core may be substantially cellulose free or comprise a combination of particulate absorbent polymer material and wood pulp. Methods for making such an absorbent core and corresponding disposable absorbent article are also disclosed.

Absorbent articles with indicia and/or color

An absorbent article is disclosed, including a three-dimensional material formed of a liquid permeable topsheet and an acquisition material. The acquisition material is positioned beneath the topsheet, and both may be formed of nonwoven material. The three dimensional material may have two surfaces and a plurality of protrusions extending in a z-direction from one of the surfaces, each protrusion having side walls defining an opening in the other of the surfaces. One of the topsheet and the acquisition material may include fibers spun of polymer resin pigmented with a first color that differs from a second color of fibers of the other of the topsheet and the acquisition material, and the differing colors are visible when viewing a wearer-facing surface of the absorbent article.

THREE-DIMENSIONAL SUBSTRATES

A liquid permeable substrate for an absorbent article is disclosed. The substrate includes a first layer including a hydrophobic material and a second layer including a hydrophilic material. The first layer is joined to the second layer. The substrate includes a plurality of recesses, a plurality of projections, and a plurality of land areas. The land areas surround at least a majority of the plurality of projections and a plurality of the recesses. The plurality of recesses, the plurality of projections, and the plurality of land areas together form a first three-dimensional surface on a first side of the substrate and a second three-dimensional surface on a second side of the substrate. The substrate has an overall z-directional height in the range of about 1000 μm to about 6000 μm according to the Overall Substrate Height Test.

Absorbent core with transversal folding lines

An absorbent core for absorbent articles such as diapers comprising a core wrap comprising a top side and a bottom side, an absorbent material between the top side and the bottom side of the core wrap, a first and second longitudinally-extending channel-forming areas substantially free of absorbent material preferably through which the top side of the core wrap is attached to the bottom side of the core wrap disposed on opposite sides of the longitudinal axis. The core has a central absorbent zone between the first and the second channel-forming areas and a first and second lateral absorbent zones disposed laterally outwardly. The absorbent core comprises at least one transversal folding line, preferably at least two transversal folding lines, in the region where the longitudinally-extending channel-forming areas are present.
