摘要： A disposable absorbent article defined by a pair of longitudinally extending side edges and a pair of end edges extending between the side edges, has a front waist region, a back waist region, and a crotch region located between the waist regions. The disposable absorbent article also includes a topsheet, a backsheet, and an absorbent core disposed between the topsheet and the backsheet. The topsheet is provided with a plurality of openings which direct bodily exudates received into or by the crotch region to a storage space disposed below the topsheet. The topsheet is spaced generally upward from the core such that the storage space is disposed between the topsheet and the core. The disposable absorbent article further includes at least one or more elongated elastic strands which are attached to the topsheet so as to space or urge the topsheet generally upwardly from the core. Moreover, portions of the topsheet between the elastic strands are tacked down to create depressions between the strands and each of the openings are located generally in one of these depressions.

摘要： A disposable absorbent article partially defined by a pair of longitudinally extending side edges and a pair of end edges extending between the side edges, includes a topsheet layer, a backsheet layer, and an absorbent core disposed between the topsheet and the backsheet. The disposable absorbent article also has a pair of side wall structures each having a pair of oppositely positioned end portions. A first side wall structure extends generally longitudinally between the core and one of the side edges and the other side wall structure extends generally longitudinally between the core and the other side edge. Further, an end strip constructed from an elastic material is positioned substantially adjacent each one of the end edges, and extends laterally between the side edges. Each of the end strips includes a fixed elastic end section disposed adjacent the end edge and secured to the topsheet, a fixed intermediate section positioned longitudinally inward of the fixed end section, and a movable, elastic inward section positioned longitudinally inward of the intermediate section. The fixed elastic section forms a waistband portion each of the front and back waist regions of the article. The intermediate section has a plurality of voids or apertures which are employed to substantially de-elasticize the intermediate section. The inward section includes a central portion spaced from the topsheet and the absorbent core, and a pair of side portions. These side portions are secured to the end portions of the side wall structures, thereby applying a contractile force between the side wall structures such the side wall structures (as well as the side edges of the article) are biased upwardly. The side wall structures and the inward sections are, therefore, secured to one another and disposed to define the sidewalls of a relatively deep containment pocket located in the crotch region.

摘要： A disposable absorbent article includes a topsheet, a backsheet and an absorbent core disposed therebetween. One or more of the backsheet, topsheet, and absorbent core is constructed of an absorbent composite that includes an absorbent layer of hydratable fine fibers in the form of microfibril obtained from cellulose or a derivative thereof and super absorbent polymer (SAP) particles bonded together by the hydratable fibers, and a nonwoven substrate supporting the absorbent layer such as SMS. The absorbent layer is coated over the surface of the nonwoven substrate. The core may include one uniform layer of the absorbent composite or a composite having one layer of the nonwoven substrate and a plurality of segmented absorbent layers applied thereon. In the latter design, the absorbent layers are spaced apart from one another to expose surface sections of the substrate. These non-coated surface sections provide wicking zones which allow room for the absorbent layers to expand and prevent gel blocking.

摘要： 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.

摘要： An absorbent material for use in a disposable absorbent product exhibiting enhanced wet strength characteristics includes a blend of cellulosic fibrous material and superabsorbent polymeric material, with a wax applied to the blend in a preferably discontinuous or non-uniform distribution for enhancing wet strength characteristics of the material, without unacceptably diminishing its absorbency. Notably, the absorbent material includes regions of relatively high densification, which can exist about particles of superabsorbent material, with application of wax in a molten form resulting in the spontaneous flow and migration of the wax to the regions of higher densification. The material can be formed with a pattern of regions of relatively high and low densification, with the wax preferentially distributed in those regions of high densification. It is believed that the wax acts to maintain the strength of hydrogen bonds formed within the absorbent material, by minimizing the effect of wetting the bonds when liquid is absorbed by the structure.

摘要： The present invention relates to an absorbent material that can be used as an absorbent core in absorbent articles such as sanitary napkins, pantiliners, incontinence products, disposable diapers, etc. The material of the present invention is a nonwoven sheet, consisting of cellulosic fibers, optionally superabsorbent polymeric material, containing no binders, latexes, etc, relying on hydrogen bonding to produce the necessary structure. The material contains density gradients which direct fluid into the material and distribute it providing more effective fluid transport and efficient utilization of storage capacity. The material consists of two regions. In the first region, the material has a low-density stratum adjacent to one surface, overlaying at least one higher density stratum adjacent to the opposite surface of the sheet. These strata create a density gradient in the thickness direction (Z-direction) of the sheet. The second region consists of a fluid distribution structure that has a higher density than at least the lower density of the strata comprising the first region. The fluid distribution structure is in direct fluid communication with the adjacent strata in the first region, along their boundaries.
