An absorbent article includes a first waist region, a second waist region, and a crotch region disposed between the first and second waist regions; and a chassis comprising a topsheet, a backsheet and an absorbent core. The article also includes a waist feature joined to the chassis a waist region and having a portion extending longitudinally outboard of the chassis in said waist region. The backsheet has a barrier layer having a maximum length, L.sub.BS. The absorbent core has absorbent material and a maximum length, L.sub.CW, and wherein L.sub.CW is substantially the same as L.sub.BS. The absorbent material is disposed in an absorbent material deposition area. The absorbent material deposition area has a maximum length, L.sub.AB, wherein L.sub.AB is about 90% or greater of L.sub.BS. The first absorbent area lateral edge is disposed a longitudinal distance, D1, from the first barrier lateral edge, wherein D1 is 5% or less of L.sub.BS.
ABSORBENT ARTICLE WITH IMPROVED FLUID HANDLING
An absorbent article having a fluid-handling system includes a fluid permeable bodyside liner; a fluid impermeable outer cover; an absorbent core disposed between the liner and the outer cover, wherein the absorbent core includes superabsorbent material and optionally fluff pulp; and a core wrap at least partially encircling the absorbent core, wherein the core wrap includes a three-dimensionally patterned, wetlaid, cellulosic tissue nonwoven material. Fibers of the nonwoven material are entirely cellulose fibers, and the core wrap includes opposing core wrap surfaces each having a textured surface. Each surface includes an average material plane, a plurality of ridges extending in a z-direction from the average material plane, and a plurality of grooves alternating with the plurality of ridges, wherein the grooves depth extend in the opposite z-direction from the average material plane.
Absorbent article
An absorbent article includes an absorbent element obtained by wrapping an absorbent body in a wrapping sheet. The wrapping sheet includes an intermediate part located on one side of a front side and a back side of the absorbent body and both side parts folded back to the other side of the absorbent body from the intermediate part. The both side parts are overlapped with each other on the other side of the absorbent body. An overlapped part is bonded through a hot melt adhesive to form a connecting portion. A surface of the absorbent body on a side of the connecting portion is bonded to an internal surface of the wrapping sheet through hot melt adhesives, and the connecting portion of the wrapping sheet extends in a width direction to extend over both widthwise sides of a slit provided in the absorbent body.
ABSORBENT ARTICLE WITH CHANNELS AND METHOD FOR MANUFACTURING THEREOF
An absorbent core comprising an absorbent material between a top core wrap sheet and a back core wrap sheet, said absorbent core having a first and second longitudinal edge and a first and second transverse edge, wherein the absorbent core is provided with at least a first elongated channel, said first channel zone has a first width (w1) at a first position and a second width (w2) at a second position, wherein the first width is larger than the second width.
Absorbent core wrap with a low basis weight nonwoven in the bottom layer
An absorbent article includes an absorbent core having an absorbent material enclosed in a core wrap having a top layer and a bottom layer. The bottom layer of the core wrap comprises a nonwoven comprising synthetic fibers, which has a basis weight from about 6 g/m.sup.2 to about 10 g/m.sup.2 and the nonwoven has a static coefficient of friction as measured in cross-machine direction of no more than 0.40.
Sheet and method for manufacturing sheet
A sheet-like article (1) for an absorbent article of the invention includes a plurality of absorbent units (4), each including a long base portion (2) and water-absorbent polymer particles (3) fixed to a surface of one face of the long base portion (2). In the sheet-like article (1), the absorbent units (4) are arranged such that their longitudinal direction is oriented in one direction. Before the water-absorbent polymer particles (3) absorb a liquid, the water-absorbent polymer particles (3) are located inward of both lateral side edge portions (2s), of the long base portion (2), that extend along the longitudinal direction. When the water-absorbent polymer particles (3) absorb a liquid, the water-absorbent polymer particles (3) swell beyond the lateral side edge portions (2s), of the long base portion (2), that extend along the longitudinal direction, and a position, in the thickness direction, of the long base portion (2) is varied from the position thereof before absorbing the liquid.
ABSORBENT ARTICLE WITH IMPROVED FLUID HANDLING
An absorbent article having a fluid-handling system includes a fluid permeable bodyside liner; a fluid impermeable outer cover; an absorbent core disposed between the liner and the outer cover, wherein the absorbent core includes superabsorbent material and optionally fluff pulp; a tissue core wrap encircling the absorbent core; and a distribution sub-layer disposed between the absorbent core and the outer cover and within the core wrap, wherein the distribution sub-layer includes a three-dimensionally patterned, wetlaid, cellulosic tissue nonwoven material. The distribution sub-layer includes opposing distribution sub-layer surfaces each having a textured surface, wherein each surface includes an average material plane, a plurality of ridges extending in a z-direction from the average material plane, and a plurality of grooves alternating with the plurality of ridges, wherein the grooves depth extend in the opposite z-direction from the average material plane.
ABSORBENT ARTICLE AND METHOD FOR MANUFACTURING AN ABSORBENT ARTICLE
An absorbent article comprises an absorbent core sandwiched between a topsheet and a backsheet. The article defines a front portion, a back portion and a crotch portion. The absorbent core comprises an absorbent component enclosed by a core cover comprising an upper and a lower side, and the core is formed with a sealing arrangement for joining the upper and lower sides comprising two channel sealings extending along an longitudinal axis in the crotch portion and defining a first channel sealing width and a second channel sealing width, respectively. The front portion of the core is formed with a recess defining a depth extending from a front edge of the core and into the front portion. A distance is defined between said front edge of the core and a front edge of each channel sealing, such that the ratio of the depth and the distance is within the interval 0.05-0.8.
ABSORBENT ARTICLE AND METHOD FOR MANUFACTURING ABSORBENT ARTICLE
An absorbent article including an absorbent core sandwiched between a liquid-permeable topsheet and a liquid-impermeable backsheet, the article defining a front portion, a back portion and a crotch portion, wherein the absorbent core includes an absorbent component enclosed by a core cover including an upper side and a lower side, and a sealing arrangement for joining the upper and lower sides, wherein the sealing arrangement includes two side seams extending along two side edges in a direction of a longitudinal axis of the core, wherein the sealing arrangement further includes at least one transversally oriented connecting sealing, the at least one connecting sealing joining the side seams, wherein the sealing arrangement further includes welding spots, wherein the sum of the area of the welding spots is constant along a direction of a transversal axis of the core.
Absorbent articles having channel-forming areas and wetness indicator
An absorbent article comprising an absorbent core having a longitudinally extending channel-forming area 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 a channel is formed along the area substantially free of absorbent material.
