摘要： In accordance with the present invention, a composite absorbent structure is formed by air laying an absorbent core comprising cellulosic fibers, typically wood pulp fibers. The absorbent core may include superabsorbent polymeric material (SAP), for enhanced liquid absorption and retention. The present invention contemplates that a nonwoven fabric layer be provided which comprises polymeric fibrous material, either in staple length or filamentary form. A composite material is formed in which the cellulosic fibers are hydrogen bonded to form an absorbent core and the nonwoven fabric layer is laminated to this hydrogen bonded layer, without adding additional non-cellulosic bonding agents (the cellulosic fibers themselves act as their own bonding agents) either to the cellulosic layer or between the cellulosic layer and the nonwoven.

摘要： A method for formation of shaped components such as shaped absorbent cores, for disposable absorbent articles, contemplates that a relatively wide web of material be provided from which the components are cut. The web of material is longitudinally slit to form a plurality of subdivided webs each having shaped components arranged in serial relationship. The shaped components of adjacent ones of the subdivided webs are nested with each other, that is, a line extending longitudinally of the web extends through the components of adjacent subdivided webs. Efficient formation is facilitated by collecting the marginal portions of the web of material, and at least partially recycling the collected portions for formation of the wide web.

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.
摘要翻译：由一对纵向延伸的侧边缘和在侧边缘之间延伸的一对端边部分地限定的一次性吸收制品包括顶片层，底片层和设置在顶片和底片之间的吸收芯。一次性吸收性物品还具有一对侧壁结构，每个侧壁结构具有一对相对定位的端部。第一侧壁结构大致纵向地延伸在芯部和一个侧边缘之间，另一个侧壁结构在芯部和另一个侧边缘之间大致纵向地延伸。此外，由弹性材料构成的端部带基本上邻近每个端部边缘定位，并且在侧边缘之间横向延伸。每个端部条包括一个固定的弹性端部分，该固定的弹性端部部分邻近端部边缘设置并固定在顶片上，固定的中间部分位于固定端部的纵向内侧;以及可移动的弹性向内部分，纵向位于中间部分的内侧。固定弹性部分形成制品的前后腰部区域的腰带部分。中间部分具有多个空隙或孔，用于使中间部分基本上去弹性。向内部分包括与顶片和吸收芯分开的中心部分和一对侧部。这些侧部固定到侧壁结构的端部，从而在侧壁结构之间施加收缩力，使得侧壁结构（以及物品的侧边缘）向上偏置。因此，侧壁结构和向内部分彼此固定并设置成限定位于裆部区域中的相对较深的容纳口袋的侧壁。
