Patterned Apertured Webs
A patterned apertured web is disclosed. The patterned apertured web includes a plurality of land areas in the patterned apertured web and a plurality of apertures defined in the patterned apertured web. At least some land areas of the plurality of land areas surround at least some apertures of the plurality of apertures. The patterned apertured web has an Effective Open Area in the range of about 3% to about 30%, according to the Aperture Test herein. The patterned apertured web has a plurality of Interaperture Distances, according to the Aperture Test herein. The Interaperture Distances have a distribution having a median and a mean. The plurality of apertures include a first set of apertures defining a first shape and a second set of apertures defining a second shape.
Garment-facing laminates and methods for making the same
An absorbent article including a liquid permeable topsheet on a wearer-facing side of the absorbent article and a garment-facing laminate on a garment-facing side of the absorbent article is disclosed. The garment-facing laminate includes a backsheet film and a nonwoven layer joined to the backsheet film. The nonwoven layer defines a plurality of apertures. At least 3 of the plurality of apertures in a repeat unit have a different Effective Aperture Area, according to the Aperture Test herein, a different shape, and a different Absolute Feret Angle, according to the Aperture Test herein. The absorbent article includes an absorbent core disposed at least partially intermediate the liquid permeable topsheet and the garment-facing laminate.
Patterned Apertured Nonwoven
The present disclosure relates to a nonwoven substrate comprising a plurality of apertures that form a pattern and define a plurality of discrete non-aperture zones. Each of the plurality of discrete non-aperture zones has a periphery formed by a continuous line of apertures, with adjacent apertures being spaced apart by an edge-to-edge distance of no more than 3 mm, while each of the plurality of discrete non-aperture zones is substantially free of apertures within the periphery. Particularly, the area ratio of such plurality of discrete non-aperture zones over the nonwoven substrate ranges from 60% to 90%, and at least some of said plurality of discrete non-aperture zones have an area of 100 mm.sup.2 or more.
ABSORBENT ARTICLES HAVING A SECONDARY TOPSHEET
An absorbent article having a liquid permeable topsheet, a liquid impermeable sheet, an absorbent core disposed between the topsheet and the backsheet, and a secondary topsheet disposed between the topsheet and the absorbent core is described. The secondary topsheet has a first layer and a second layer. The first layer is located between the topsheet and the second layer, and a mean pore size of the first layer is larger than a mean pore size of the topsheet.
Substrates having repeating patterns of apertures for absorbent articles
The present disclosure is directed to substrates or topsheets having repeating patterns of apertures for absorbent articles. Each of the repeat units comprises at least three apertures.
Three-dimensional substrates and absorbent articles having the same
A three-dimensional substrate has a central longitudinal axis extending perpendicular to a central lateral axis. A line taken in a direction parallel to or perpendicular to the central lateral axis of the three-dimensional substrate has a non-apertured, first visually discernible zone in the substrate and a second visually discernible zone in the substrate. The first visually discernable zone has a pattern of three-dimensional features on a first surface or a second surface. At least some of the three-dimensional features define a microzone having a first region and a second region. The first region and the second region have a difference in value for an intensive property. The second visually discernable zone defines apertures. The apertures have an Effective Aperture Area in a range of about 0.3 mm.sup.2 to about 15 mm.sup.2.
PATTERNED APERTURED WEBS
A patterned apertured web is disclosed. The patterned apertured web includes a plurality of land areas in the patterned apertured web and a plurality of apertures defined in the patterned apertured web. At least some land areas of the plurality of land areas surround at least some apertures of the plurality of apertures. The patterned apertured web has an Effective Open Area in the range of about 3% to about 30%, according to the Aperture Test herein. The patterned apertured web has a plurality of Interaperture Distances, according to the Aperture Test herein. The Interaperture Distances have a distribution having a median and a mean. The plurality of apertures include a first set of apertures defining a first shape and a second set of apertures defining a second shape.
