ABSORBENT ARTICLE
Provided is an absorbent article having excellent shape retention of an absorber even when an external force is applied thereto. The present invention is an absorbent article having: an aqueous-liquid absorbing part having crosslinked polymer particles having as essential constitutional units thereof a water-soluble vinyl monomer and/or a vinyl monomer which became the water-soluble vinyl monomer by hydrolysis, and a crosslinking agent; and a nonwoven fabric having porous fibers as an essential constituent thereof, the crosslinked polymer particles preferably absorbing 40 times the weight thereof of physiological saline 40 in 40-150 seconds.
Absorbent structure comprising release structure
An absorbent article comprising a liquid pervious topsheet, a liquid impervious backsheet, and an absorbent structure positioned in between said topsheet and said backsheet, wherein the absorbent structure comprises an absorbent core positioned in between the topsheet and the backsheet, a release structure being positioned in fluid communication with the absorbent core, said absorbent core comprising little to no cellulose fibers and/or fluff pulp and said absorbent core comprising an absorbent polymer material for absorbing and permanently holding fluids received from the topsheet and the release structure, wherein said release structure comprises at least one fibrous substrate structure having the capacity to receive and temporarily hold the fluids in proximity to the absorbent core so that the fluids can subsequently be transferred and released to and absorbed by the absorbent core.
ABSORBER AND DISPOSABLE DIAPER
A sheet-like absorber including: a channel portion that is formed over an entire length of one sheet face; a first absorption layer that forms another sheet face; and plural second absorption layers that form the one sheet face, wherein, where the first absorption layer and the second absorption layers are each fiber layers formed of heat-fusible fibers and have an absorbent polymer incorporated inside the fiber layers, a content of the absorbent polymer per unit area in the second absorption layers is greater than a content of the absorbent polymer per unit area in the first absorption layer, and a more durable hydrophilicity for maintaining hydrophilicity of the fibers is imparted to fibers that form portions of the second absorption layers on an opposite side from a first absorption layer side than to fibers that form portions of the second absorption layers on the first absorption layer side.
PATTERNED FIBROUS SUBSTRATES
Patterned fibrous substrates having a plurality of individual fibers, a first region, and a second region are provided. The patterned fibrous substrates have a plurality of individual fibers of the first region having a first diameter and a plurality of individual fibers of the second region have a second diameter, wherein the first diameter is less than the second diameter. The individual fibers of the first region and the individual fibers of the second region are substantially free of bonds, other than primary bonds. The first region has a first C.I.E. L* score, and the second region has a second C.I.E. L* score, according to the Color Test Method. The first C.I.E. L* score is different than the second C.I.E. L* score.
AIRLAID NONWOVEN
Provided is a composite sheet material having a first layer and an airlaid nonwoven layer overlying the first layer wherein the airlaid nonwoven layer includes a blend of bamboo derived staple fibers and non-cellulose staple fibers, and in which the airlaid nonwoven layer includes a first surface disposed towards, and thermally bonded, to a surface of the first layer, and a second surface defining an outer surface of the composite sheet material.
ABSORBENT PRODUCT COMPRISING A NONWOVEN MATERIAL
An absorbent product includes a nonwoven material arranged to be in contact with skin of a user during use of the absorbent product. The nonwoven material includes, at least on a skin contacting surface, a mixture of non-absorbent and absorbent fibres. The absorbent fibres are present in an amount of 2-30% by weight, or about 2-10% by weight, based on the total weight of the fibres in the nonwoven material. The non-absorbent fibres have a coarseness of 1.8 to 10 dtex and the absorbent fibres have a coarseness of 1 to 10. Also disclosed is a use of a nonwoven material in an absorbent product to reduce wet friction between the nonwoven and skin of a user.
TAMPON WITH CONSOLIDATED FIBROUS ASSEMBLY AND METHOD OF MAKING
The present disclosure describes a tampon article, a composite fibrous web, and a method of making same. Such an article includes an outer carrier component including an inner surface that defines an internal void. Including an absorbent component elongate along an axis and is disposed in the internal void. The absorbent component includes an outer surface that extends about the axis and faces the inner surface. The absorbent component further includes a composite fibrous web of staple cellulosic fibers and a meltspun web of filaments entangled with the web of staple cellulosic fibers. The composite fibrous web can be in a compressed configuration in the internal void such that at least portion of the outer surface of the absorbent component is defined by the meltspun web of filaments. The tampon can include a withdrawal cord coupled to the absorbent component.
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).
ABSORBENT CORE COVER FOR SUPER-ABSORBING ABSORBENT CORES OF SANITARY PRODUCTS
The present invention relates to an absorbent core for sanitary products with an absorption matrix which comprises a high proportion of super-absorbing particles, and an absorbent core cover for enveloping the absorption matrix, wherein the absorbent core cover comprises at least one upper side sheet and one bottom side sheet, and the absorbent core cover comprises at least one connection region spaced apart from the edge of the absorbent core in which the upper side sheet and the bottom side sheet are connected to each other. Here, at least the upper side sheet of the absorbent core cover is embodied as a fleece composite with a fixing layer with a low permeability to retain the particles in the absorption matrix, and a transfer layer for acquiring fluid. Moreover, the invention relates to a sanitary product having such an absorbent core, the use of a fleece composite as an absorbent core cover, and a method for manufacturing a fleece composite for the upper side sheet of the absorbent core cover.
