摘要:
A process is claimed for making a composite sheet useful as topsheet with one or more openings to receive fecal material useful for an absorbent article, said composite sheet comprising a wrinkled, patterned elasticized region that comprises a patterned first sheet and an elastic material said first sheet being patterned with troughs, that are typically compacter, i.e. of higher density, prior to attachment to the elastic material. The troughs are attached to the elastic material. The resulting composite sheet has a uniform wrinkle pattern. Also claimed are specific absorbent articles. Also claimed are composite sheets with a specific residual strain and peel force value.

摘要:
An absorbent articles, such as diapers, training pants, adult incontinence articles, feminine protection articles and the like having a specific elasticated topsheet comprising multitude of elasticated areas and one or more openings to receive e.g. feces, the elasticated areas being typically straight, but the elasticated areas operating jointly to provide a diverting-like elastic behavior, and the elasticated areas having optionally different elastic properties.

摘要:
An absorbent article comprises a liquid permeable topsheet, a liquid impermeable backsheet, an absorbent core positioned at least partially intermediate the topsheet and the backsheet, and a distribution material comprising a wet-laid, three-dimensional fibrous substrate comprising at least 80% pulp fibers by weight of the wet-laid, three-dimensional fibrous substrate. The wet-laid, three-dimensional fibrous substrate comprises a continuous network region, a plurality of discrete zones, and a plurality of transition regions. The transition regions are positioned intermediate the continuous network region and at least some of the plurality of discrete zones.
摘要:
A method and apparatus for forming a batt of particulate material which may be used in an absorbent article. The apparatus may include a vacuum zone, an air impermeable fence zone adjacent to the vacuum zone, and an air permeable fence zone adjacent to the vacuum zone. The air permeable fence zone may comprise an ambient air entry conduit in communication with an ambient air exit port. The method may include providing a laydown drum and a first web of material, positioning the first web of material substantially adjacent to the laydown drum, generating a vacuum through the laydown drum, depositing particulate matter onto the first web of material, and rotating the laydown drum.

Methods and apparatuses herein may provide for the application of viscous fluids, such as adhesives, in pre-determined patterns to an advancing substrate. The fluid application apparatus may include a slot die applicator and a substrate carrier. The substrate carrier may include one or more pattern elements and may be adapted to advance the substrate past the slot die applicator as the slot die applicator discharges adhesive onto the substrate. In operation, the substrate is disposed on the substrate carrier; the substrate carrier advances the substrate past the slot opening of the slot die applicator. In turn, the substrate is intermittently compressed between the slot die applicator and the pattern surface of the pattern element. As the substrate is intermittently compressed, adhesive discharged from the slot die applicator is applied onto the substrate in an area having a shape substantially the same as a shape defined by the pattern surface.
摘要:
A method and apparatus for forming a wad of particulate material which may be used in an absorbent article. The apparatus may include a laydown drum having a plurality of vacuum zones, a plurality of fence zones, and a plurality of blow-off zones. The plurality of vacuum zones may be substantially permeable to permit vacuum air to pass through and into the laydown drum. The plurality of fence zones may be substantially impermeable to inhibit air to pass through. The plurality of blow-off zones may be substantially permeable to permit blown air to pass out of and through said laydown drum. The apparatus may also include a deposition chute for depositing particulate material on a web of material in close proximity to the laydown drum. A shield may also be attached to the deposition chute.
