Apertured nonwoven
An apertured nonwovens having a first nonwoven layer is described. The first nonwoven layer includes cellulose-based fibers and a plurality of apertures, wherein the plurality apertures have a minimum aperture distance between two adjacent apertures which has a relative standard deviation no greater than about 40%, as measured according to the Aperture Quality Test. The apertures have an aperture size no greater than about 2.2 mm.sup.2 and have an occlusion no greater than about 9%, as measured according to the Aperture Quality Test, or the apertures have an aspect ratio no greater than about 2.5 as measured according to the Aspect Ratio Test.
Garment-like absorbent articles
Garment-like absorbent articles are disclosed. The garment-like absorbent articles may include two nonwoven components that have coordinating and/or substantially similar repeat patterns of apertures and/or bonds. The two nonwoven components may also have certain repeat unit areas, repeat unit width, and repeat unit lengths to aid in softness and to provide improved aesthetic appearance to consumers.
Laminate Webs And Absorbent Articles Having The Same
A laminate web having a polymer film layer and a nonwoven layer is disclosed. The polymer film layer makes up a first side of the laminate web and the nonwoven layer makes up a second side of the laminate web. The laminate web has a plurality of first elements extending from the polymer film. The web also has a plurality of second elements formed outwardly from the first side of the laminate web.
Absorbent article with raisable topsheet
An absorbent article for personal hygiene having a front edge and a back edge and comprising a liquid impermeable backsheet, a liquid permeable topsheet, an absorbent core and a pair of barrier leg cuffs disposed symmetrically relative to the longitudinal axis. Each barrier leg cuff is defined by a proximal edge attached to the rest of the article and an elasticized terminal edge that can protrude upwards. The topsheet comprises a raisable region that is attached to the barrier leg cuffs so that when the barrier leg cuffs are raised, the raisable region is lifted up by the barrier leg cuffs and an empty volume is formed between the raisable region and the chassis of the article underneath.
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 has an array of apertures forming apertured indicia. The array of apertures includes a first plurality of apertures having a first aspect ratio; a second plurality of apertures having a second aspect ratio and a first Absolute Feret Angle; and a third plurality of apertures having a third aspect ratio and a second Absolute Feret Angle, wherein the first Absolute Feret Angle and the second Absolute Feret Angle are different, and wherein the first aspect ratio is less than the second and third aspect ratios.
Laminate webs and absorbent articles having the same
A laminate web having a polymer film layer and a nonwoven layer is disclosed. The polymer film layer makes up a first side of the laminate web and the nonwoven layer makes up a second side of the laminate web. The laminate web has a plurality of first elements extending from the polymer film. The web also has a plurality of second elements such as recesses, protrusions, apertures, embossing and combinations thereof.
Apertured topsheets and methods for making the same
A diaper includes a liquid permeable topsheet including a patterned apertured nonwoven material. The patterned apertured nonwoven material includes a plurality of land areas in the patterned apertured nonwoven material and a plurality of apertures defined in the patterned apertured nonwoven material. At least some land areas of the plurality of land areas surround at least some apertures of the plurality of apertures. The plurality of apertures are non-homogeneous in a repeat unit such that at least two apertures of the plurality of apertures have a different size or a different shape.
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.
Pant-Type Wearable Article
Disclosed is a wearable article comprising front and back elastic belt regions and a crotch region between the front and back elastic belt regions; the front and back elastic belt regions each comprising a laminate, an elastic bonding continuously bonding an elastic member in the direction of stretch, and a vertical bonding applied to at least one of inner and outer sheets to intermittently bond the elastic member to at least one of the inner and outer sheets, the vertical bonding having a transverse dimension VG2 and spaced apart from each other with a transverse pitch VG1, wherein the outer sheet comprises a repeating pattern of apertures, the repeating pattern of apertures spaced apart from each other with a longitudinal pitch DF2, and spaced apart from each other with a transverse pitch DF1, wherein VG1 is greater than DF1, and wherein the repeating pattern of apertures have a Longitudinal Orientation.
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 plurality of apertures include a first set of apertures defining a first shape and a second set of apertures defining a second shape. The first shape is positioned within the second shape.
