SHAPED PERMEABLE MATERIAL COMPOSITE FOR USE IN AN ABSORBENT ARTICLE
A permeable material composite is provided for use in an absorbent article. The permeable material composite includes a permeable material layer that is a low-strength material layer and having a tensile strength of less than 3 N/mm. The permeable material layer has an edge having a contour and being a shaped edge providing the permeable material composite with a non-rectangular shape. The permeable material layer is reinforced along the shaped edge with a reinforcement material that is attached to the permeable material layer. The reinforcement material has a shaped outer edge having a contour that coincides fully or partly with the contour of the shaped edge of the permeable material layer.
Apertured webs and methods for making the same
A patterned apertured web includes a plurality of first arrays forming a first zone in the patterned apertured web. At least some of the first arrays include a first plurality of land areas and a first plurality of apertures. At least some of the first plurality of land areas surround at least some of the first plurality of apertures. The first plurality of apertures of the first zone have a plurality of Interaperture Distances, according to the Aperture Test. The Interaperture Distances of the first zone have a first distribution having a first mean and a first median. The first mean is greater than the first median by at least 4%.
ABSORBENT ARTICLE WITH AN EXUDATE MANAGEMENT LAYER
An absorbent article can have a topsheet layer, a liquid impermeable layer, and an absorbent core positioned between the topsheet layer and the liquid impermeable layer. The absorbent article can further include an exudate management layer in fluid communication with the topsheet layer. In various embodiments, the exudate management layer can be positioned on a body facing surface of the topsheet layer. In various embodiments, the exudate management layer can be positioned between the topsheet layer and the absorbent core. The exudate management layer has a first component which defines an opening for direct passage of body exudates into the absorbent core. The exudate management layer has a second component which at least partially overlaps the first component of the exudate management layer and further extends in the longitudinal direction of the absorbent article in a direction towards the posterior region of the absorbent article.
ABSORBENT ARTICLE AND METHOD FOR MANUFACTURING SHEET WITH THREE-DIMENSIONAL OPENING USED THEREFOR
A topsheet (2) includes a laminate of a first nonwoven fabric (20) and a second nonwoven fabric (21), the two nonwoven fabrics (20, 21) are fused together at peripheral edges of openings (22) to form a plurality of fusion bond portions (23), and the first nonwoven fabric (20) in a region other than the fusion bond portions (23) protrudes in a direction away from the second nonwoven fabric (21) to form a plurality of projections (24) protruding toward the skin of a wearer. Each fusion bond portion (23) has a protrusion (26) protruding toward a sublayer (3), and a plurality of the protrusions (26) are dispersed on a surface (2b) of the topsheet (2) facing the sublayer (3). When the topsheet (2) is pressed toward the sublayer (3), the sublayer (3) is partially pressed by the protrusions (26).
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.
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.
Shaped Nonwovens that Exhibit High Visual Resolution
A nonwoven fabric is disclosed. The nonwoven fabric can include a first surface and a second surface and at least a first visually discernible zone of three-dimensional features on one of the first or second surface. Each of the three-dimensional features can define a microzone comprising a first region and a second region. The first and second regions can have a difference in values for an intensive property, and the first visually discernible zone can exhibit a high visual resolution.
Absorbent article with partially separable, skin-contacting topsheet layer
An absorbent article has a longitudinal direction, a transverse direction, and a depth direction and includes absorbent article opposing first and second longitudinal ends, and absorbent article opposing lateral side edges extending between the absorbent article opposing first and second longitudinal ends. The absorbent article comprises a liquid permeable first topsheet layer having first topsheet layer opposing lateral side edges, and first topsheet layer opposing longitudinal ends as well as a liquid permeable second topsheet layer subjacent to the liquid permeable first topsheet layer. The liquid permeable second topsheet layer has second topsheet layer opposing lateral side edges, and second topsheet layer opposing longitudinal ends, and is attached at or along two opposing attachment zones to the liquid permeable first topsheet layer along or adjacent the first topsheet layer opposing lateral side edges.
