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 for use in absorbent articles
An absorbent core suitable for use in an absorbent article comprising: a first absorbent layer, the first absorbent layer comprising a first substrate, and a layer of cross-linked cellulose fibers deposited on the first substrate, a second absorbent layer, the second absorbent layer comprising a second substrate, a layer of superabsorbent polymer particles deposited on the second substrate and a fibrous layer of thermoplastic adhesive material covering the layer of superabsorbent polymer particles. The first and second absorbent layers being combined together such that at least a portion of the fibrous layer of thermoplastic adhesive material contacts at least a portion of the layer of cross-linked cellulose fibers of the first absorbent layer.
ABSORBENT ARTICLE
An absorbent article (1) comprising a top sheet (2), a back sheet (3) and an absorbent body (11) provided therebetween, wherein: the absorbent body (11) comprises plural layers of a sheet member and has a sealed part (14) in which the sheet members are bonded to each other and a non-sealed part (15) in which the sheet members are not bonded to each other, and an absorbent material is disposed in the non-sealed part (15), thereby forming an absorption area (16); the absorbent material disposed in the absorption area (16) contains an absorbent polymer in a proportion of 50 mass % or more the absorption area (16) is provided in a stripe shape extending in the front-rear direction; concave grooves (17) are formed from the top sheet (2) to the absorbent body (11) on one side and the other side in the width direction on a skin facing side of the absorbent article (1); and the concave grooves (17) are arranged such that the entire concave groove (17) overlaps with the absorption area (16) and end portions in the front-rear direction of the concave groove (17) are curved inward in the width direction.
Absorbent articles having channel-forming areas and wetness indicator
An absorbent article comprising an absorbent core having at least two longitudinally extending channel-forming areas 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 the core wrap forms channels along these areas substantially free of absorbent material.
Absorbent article
An absorbent article comprising a polymer sheet 4 in which a super absorbent polymer 12 exists between an upper layer sheet 10 arranged on the skin side and a lower layer sheet 11 arranged on the non-skin side is included. A fiber absorber 5 including pulp fiber is disposed adjacent to the surface on the skin side of an area corresponding to a body fluid discharge region H of a wearer in the polymer sheet 4. The super absorbent polymer 12 is not arranged in an area which overlaps with the fiber absorber 5, and is arranged in the other area. The water absorption rate of the absorbent article is not reduced even when water is repeatedly absorbed. Additionally, leakage is prevented, a wearing feeling is not worsened, and the adsorbent article may have a reduction in thickness.
ABSORBENT CORES HAVING MATERIAL FREE AREAS
An absorbent core, for use in an absorbent article, including a core wrap enclosing an absorbent material and including superabsorbent polymer particles. The core wrap includes a top side and a bottom side, and the absorbent core includes one or more area(s) substantially free of absorbent material through which the top side of the core wrap is attached to the bottom side of the core wrap, so that when the absorbent material swells the core wrap forms one or more channel(s) along the area(s) substantially free of absorbent material. The superabsorbent polymer particles have a time to reach an uptake of 20 g/g (T20) of less than 240 s as measured according to the K(t) test method.
Indirect printing of AGM
The present invention relates to a method of applying absorbent gelling material (AGM) granules by indirect printing onto an carrier layer for use in an absorbent article, particularly diaper for babies or adults, training pants, pull-up diapers (diaper pants), sanitary napkins, panty liners or the like. These articles typically comprise the carrier layer with the AGM particles together with further layers, making up the complete article.
MULTI-LAYERED ABSORBENT ARTICLE
An absorbent article for menstrual and/or incontinence purposes, having a unique two-layer acquisition and absorbent structure. The cover layer includes a nonwoven material. The absorbent core includes multiple strata including super absorbent, fiber material that is pulp and/or bicomponent fibers, and a binder material. The total thickness of the absorbent article is less than or equal to the thickness of absorbent articles of similar absorbent characteristics. The absorbent article includes various absorbent properties that are improved despite parity or reduction in overall thickness.
Ultra thin laminate with particulates in dense packages
The present invention is directed to a method of forming a laminate absorbent structure, and a resulting package containing a single continuous running web of the laminate material. Notably, formation of the material is effected by blending a curtain of adhesive fibers with a curtain of particulate material, and depositing the mixture on a moving substrate, preferably provided in the form of a tissue layer. A second substrate, also preferably comprising a tissue layer, is applied on top of the deposited mixture, and pressure applied to form the laminated structure. Notably, attendant to packaging of the laminated material, adjacent layers of the material tend to nest into one another, to form a sandwich in which the density of the material in the package is more than 1.5 times the density of the material after its removal from the package.
Absorbent pad
Disclosed is an absorbent pad which efficiently diffuses excretory fluid and gives no sense of discomfort to a wearer even after excretion. A front sheet and a rear sheet are joined to each other at a plurality of first junctions and a plurality of second junctions, and when viewed in plan, the first junctions extending in a longitudinal direction are arranged at predetermined intervals in a width direction, and second junctions extending in the width direction are arranged at predetermined intervals in the longitudinal direction. A plurality of cells, each of which is defined by an adjacent pair of the first junctions and an adjacent pair of the second junctions, is formed between the front sheet and the rear sheet spaced apart from each other. An opening extending in the longitudinal direction is formed in at least one of the first junctions.
