PROCESS FOR MAKING AN ABSORBENT ARTICLE COMPRISING A TOPSHEET/ACQUISITION LAYER LAMINATE
A process of making an absorbent article is disclosed. A liquid permeable topsheet web extending substantially continuously in a machine direction a backsheet web, and an acquisition layer are provided. The topsheet web has first and second surfaces. The backsheet web extends substantially continuously in the machine direction. The acquisition layer has a first and second surface. The topsheet and acquisition layer are aligned in a face to face relationship such that the second surface of the topsheet in in contact with the first surface of the acquisition layer and simultaneously mechanically deformed which combines the topsheet with the acquisition layer. The topsheet web and acquisition layer are nested together such that a majority of the three-dimensional protrusions formed in the topsheet web coincide with and fit together with a majority of the three-dimensional protrusions formed in the acquisition layer to provide a topsheet/acquisition layer laminate web having three-dimensional protrusions.
Patterned apertured webs and methods for making the same
A disposable absorbent article having a topsheet, a backsheet, and an absorbent core disposed therebetween is described herein. The topsheet includes an array of apertures and a first array of structures which are disposed adjacent the array of apertures. A first plurality of the array of apertures is disposed generally parallel to a longitudinal axis, a second plurality of apertures has a first Absolute Feret angle, and a third plurality of apertures has a second Absolute Feret angle. The first Absolute Feret angle is different than the second Absolute Feret angle.
Absorbent article containing a nonwoven web formed from a porous polyolefin fibers
An absorbent article containing a nonwoven web that includes a plurality of polyolefin fibers is provided. The polyolefin fibers are formed by a thermoplastic composition containing a continuous phase that includes a polyolefin matrix polymer and nanoinclusion additive is provided. The nanoinclusion additive is dispersed within the continuous phase as discrete nano-scale phase domains. When drawn, the nano-scale phase domains are able to interact with the matrix in a unique manner to create a network of nanopores.
PATTERNED APERTURED WEBS AND METHODS FOR MAKING THE SAME
A disposable absorbent article having a topsheet, a backsheet, and an absorbent core disposed therebetween is described. The topsheet includes a plurality of apertures arranged in a first zone and a first plurality of structures which are disposed adjacent to the first plurality of apertures. The plurality of apertures have an Effective Aperture Area of from between 0.5 mm.sup.2 to about 8 mm.sup.2 as measured by the Aperture/Feret Angle test as described herein, and the topsheet has a top layer and a lower layer, wherein the top layer is more hydrophobic than the lower layer.
Process for making an absorbent article comprising a topsheet/acquisition layer laminate
A process of making an absorbent article comprising providing a liquid permeable topsheet web extending substantially continuously in a machine direction. The topsheet web having a first and second surface and a backsheet web extending substantially continuously in the machine direction and an acquisition layer having a first and second surface. The process comprises aligning the topsheet web and the acquisition layer in a face to face relationship such that the second surface of the topsheet in in contact with the first surface of the acquisition layer and simultaneously mechanically deforming and combining the topsheet web together with the acquisition layer. The topsheet web and acquisition layer are nested together such that a majority of the three-dimensional protrusions formed in the topsheet web coincide with and fit together with a majority of the three-dimensional protrusions formed in the acquisition layer to provide a topsheet/acquisition layer laminate web having three-dimensional protrusions.
Absorbent article with an apertured multi-layered topsheet
An absorbent article (100-1200) is capable of providing comfort to the wearer and can maintain dryness and inhibit the leakage of fluid. The absorbent article (100-1200) includes a multi-layered topsheet (138). The multi-layered topsheet (138) includes a first topsheet layer (106) having an opening (148) and a second topsheet layer (108) disposed under the first topsheet layer (106). The first topsheet layer (106) and the second topsheet layer (108) are joined together by a seal that, in one embodiment, generally corresponds with the shape of the opening (148). Further, a first sub-topsheet layer (116) is situated beneath the multi-layered topsheet (138) and has an opening (150) that is smaller than the first topsheet layer opening (148). This combination of openings (148, 150) situated one below the other provides for an absorbent article (100-1200) that can maintain a high level of dryness and its ability to conform to the wearer's body, and inhibit the leakage of bodily fluids due to a funnel-like effect.
Absorbent article with three-dimensional film for liquid distribution
An absorbent article with a three-dimensional film transfer layer having an open lattice structure formed from a single film for improved user properties.
Disposable diaper with buttocks part stretching unit
In a disposable diaper, a leg stretching unit stretchable in a longitudinal direction is disposed at an inside of a widthwise direction than a pair of leg opening units. An area between a backside leg opening unit and a straight line passing through a center in the widthwise direction and parallel to the longitudinal direction is larger than an area between a foreside leg opening unit and a straight line passing through a center of the longitudinal direction of the leg opening unit and extending in the longitudinal direction. A buttocks part stretching unit running across a crotch region and the back waistline region and stretchable in the longitudinal direction is disposed at an outside of the widthwise direction than the leg stretching unit. A front end of the buttocks part stretching unit is positioned more backward than a center of the longitudinal direction of the leg opening unit.
MOIR? EFFECT LAMINATES AND METHODS FOR MAKING THE SAME
A laminate comprises a first layer comprising a plurality of lower opacity zones positioned within a higher opacity zone is provided. The plurality of lower opacity zones form a first pattern. The laminate comprises a second layer comprising a second pattern. The laminate comprises a non-joined span of the first and second layers having a dimension of at least about 20 mm. A first portion of the second pattern is visible through at least some of the plurality of lower opacity zones when the first layer, within the non-joined span, is in a first position relative to the second layer, within the non-joined span. A second portion of the second pattern is visible through at least some of the plurality of lower opacity zones when the first layer, within the non-joined span, is in a second position relative to the first layer, within the non-joined span.
