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.

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 intermediate layer are provided. The topsheet web has first and second surfaces. The backsheet web extends substantially continuously in the machine direction. The intermediate layer has a first and second surface. The topsheet and intermediate 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 intermediate layer and simultaneously mechanically deformed which combines the topsheet with the intermediate layer. The topsheet web and intermediate 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 intermediate layer to provide a topsheet/intermediate layer laminate web having three-dimensional protrusions.

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.

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.

NONWOVEN FABRIC

A nonwoven fabric, comprising thermoplastic fibers, a first surface side and a second surface side which is a surface side opposite to the first surface side, wherein the nonwoven fabric has outer surface fiber layers on the first surface side and the second surface side in which fibers are oriented in plane direction; and a plurality of connecting portions arranged between the outer surface fiber layer on the first surface side and the outer surface fiber layer on the second surface side, in which fibers are oriented in thickness direction of the nonwoven fabric; and part of the fibers is fused to each other between the outer surface fiber layer on the first surface side, the outer surface fiber layer on the second surface side, and the connecting portions.

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

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, wherein the mean is different than the median. 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.

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 a first zone disposed between a second zone and a third zone; a first end area and a second end area; and an array of features which includes one of apertures, tufts, ridges, or grooves disposed in the first zone. A plurality of bond sites are disposed in the second and third zones. The plurality of bond sites are configured in a curvilinear manner in at least the first end area or the second end area and mask a boundary of the first zone.
