Abstract: The present disclosure relates to absorbent garments having a dryness layer that can comprise one or more laminates and one or more channels to facilitate liquid acquisition and retention. Laminate(s) can include an absorbent lamina disposed between substrate laminae, each comprising tissue and/or a nonwoven. Some dryness layers can have a folded laminate that defines a longitudinally-extending channel. Some dryness layers can have two or more laminate strips that are laterally spaced apart along a width of the dryness layer such that one or more longitudinally-extending channels are defined therebetween.

Abstract: Absorbent laminates and multi-layer, folded absorbent cores comprising the absorbent laminates for use in absorbent articles are presented. Specifically, multi-layer, folded absorbent cores are presented that are formed from an absorbent laminate comprising an absorbent layer between two tissue layers, in which the absorbent core includes a central channel running longitudinally along the core and crenellations profiled along the thickness of the core and providing enhanced liquid distribution across the core surface area or profile and improved liquid absorption into the laminate.

Abstract: The present disclosure relates to absorbent articles having an absorbent core that can comprise a laminate longitudinally folded such that the absorbent core includes a lower laminate layer and, within each of first and second longitudinally-extending edge regions, one or more folded laminate layers. A center region of the lower layer can be bonded to a chassis and can span a lateral distance smaller than the width of the absorbent core such that at least a portion of the absorbent core in each of the edge regions is configured to lift away from the chassis. The present absorbent cores can thus define a containment zone to reduce liquid and/or feces leakage.

Abstract: This disclosure includes absorbent articles comprising first and second absorbent cuffs to prevent leaks. The present articles can comprise a chassis having opposing front and rear portions and a crotch portion extending longitudinally between the front and rear portions. An absorbent core can extend longitudinally along the crotch portion, and the first and second absorbent cuffs can extend longitudinally along the crotch portion as well. The absorbent cuffs can be positioned such that at least a portion of the absorbent core is positioned between the absorbent cuffs, and each can comprise a liftable portion and one or more elastics configured to urge the liftable portion away from the chassis and toward a wearer when the absorbent article is worn. Absorbent or hydrophobic end caps can extend across the ends of the absorbent cuffs.

Abstract: The present disclosure includes cellulosic fiber barrier layer having a hydrophobic sizing to cause the barrier layer to exhibit hydrophobic properties. For example, the present cellulosic fiber barrier layers can be configured to have a high hydrostatic head (e.g., more than 200 mm H2O) while retaining a high air permeability (e.g., 0.5 ft3/min-ft2). The present disclosure also includes laminates (e.g., a breathable backsheet assembly) including one of the present cellulosic fiber barrier layers and a nonwoven support layer positioned beneath and coupled (e.g., bonded) to the barrier layer, such that the laminate is configured to exhibit desirable liquid-barrier performance (e.g., pinhole-free performance at 400 mm H2O for 10 minutes, and/or the like). The present disclosure also includes disposable absorbent garments including at least one of the present cellulosic fiber layers and laminates (e.g., including one of the present laminates as a backsheet for the disposable absorbent garment).

Abstract: A liquid distribution mat that is a wet-laid mat of enhanced cellulosic fibers that are cellulosic fibers cross-linked in sheet form, as well as methods of making the liquid distribution mat. The liquid distribution mat has high vertical wicking properties and excellent structural integrity in both wet and dry states. The liquid distribution mat is suitable for use in an absorbent article. When used in an absorbent article such as a baby diaper, the liquid distribution mat rapidly acquires and transports bodily discharges from the point of insult to other regions of the absorbent article, thereby maximizing the utilization of the absorbent article.

Abstract: An odor-inhibiting fiber having a cellulosic fiber and an odor-inhibiting formulation. The odor-inhibiting formulation may contain an odor-inhibiting agent, such as a biocide, an enzyme, a urease inhibitor. The odor-inhibiting formulation also may contain a liquid carrier such as a hydrophobic or hydrophilic organic liquid, or a mixture of a hydrophobic and hydrophilic organic liquid. The cellulosic fiber is impregnated with the odor-inhibiting formulation to produce fiber having odor-inhibiting characteristics. The resultant odor-inhibiting fiber is useful in making absorbent articles with odor-inhibiting characteristics. The fiber of the embodiments prevents odor by inhibiting bacteria growth and ammonia production, especially when used in an absorbent article such as a diaper or adult incontinence device.

Abstract: A method for making acquisition fiber in sheet form that exhibits a low degree of yellowing and is substantially free of burnt-like odor. The acquisition fiber may be produced by treating cellulosic fibers in sheet form with a treatment composition solution that includes a cross-linking agent and a modifying agent. After the fibers are impregnated with the treatment composition, the fibers are dried and cured, and then treated with an odor removing agent. The resultant acquisition fiber may be used in absorbent articles, such as personal care products.

Abstract: A plasticizing formulation for producing plasticized fluff pulp. The plasticizing formulation, which preferably is an aqueous solution, includes a primary plasticizing agent, and optionally a secondary plasticizing agent. Preferably, the primary plasticizing agent is 1,4-cyclohexanedimethanol, and the secondary plasticizing agent is triacetin. When the plasticizing formulation is applied to a cellulosic fluff pulp, a plasticized fluff pulp is produced. The resultant plasticized fluff pulp may have one or more of the following: reduced Kamas energy, Mullen strength, and fiber knot and nit contents, when compared to the base cellulosic fluff pulp fiber that is not plasticized.

Abstract: The present invention relates to cross-linked cellulosic fiber having improved absorbency characteristics when compared to conventional cross-linked fibers. The cross-linked cellulosic fiber is obtainable by reacting pulp in the sheet or fluff form with one or more reagents selected from organic molecule having acid and aldehyde functional groups “acid aldehydes.” The invention also relates to a method of producing the cross-linked fiber. The method includes heating the treated cellulosic fibers to promote intrafiber cross-linking. The cross-linked fibers are characterized by having an improved centrifuge retention capacity, fluid acquisition rate, resiliency, absorbent capacity, absorbency under load, and other absorbent properties. The inventive cross-linked fibers are useful in forming absorbent composites, and in particular absorbent cores for use in absorbent articles.

Abstract: A breathable barrier composite of cellulosic fibers includes a compressed mixture of hydrophobic cellulosic fibers and thermally-bondable polyolefin fibers. The composite has a combination of high liquid barrier properties, and high air and moisture vapor porosity. The composite also has a very soft and cottony texture. The breathable barrier composite may optionally contain a nonwoven layer, such as a spunbond or an SMS nonwoven, a polyolefin film layer, or a nonwoven wipe layer.
