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.
Absorbent product comprising colored areas
An absorbent product includes a liquid permeable topsheet, a liquid impermeable backsheet, and an absorbent core enclosed between the topsheet and the backsheet. The absorbent core includes an absorbent fibrous layer, a liquid inlet layer, and a carrier layer, in which a transversally central region is arranged in the liquid inlet layer. The central region extends along the entire longitudinal length of the absorbent core, and includes a plurality of slits arranged in a pattern. The slits are in the form of dilated slit openings in a part of said central region, which is comprised in an intermediate portion of the absorbent core, and the slits are in the form of non-dilated slits in parts of said central region, which are comprised in one or both of front and rear portions of the absorbent core.
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.
Nonwoven Webs With Hydrophobic And Hydrophilic Layers
A nonwoven web for use in an absorbent article is described. The nonwoven web has first and second nonwoven layers. The first nonwoven layer has a first plurality of fibers, an additive disposed, at least in part, on a portion of the first plurality of fibers, a first side and an opposing second side, wherein second side has a plurality of discontinuities. The second nonwoven layer has a second plurality of fibers, a first surface and an opposing second surface, and a plurality of tufts extending through at least a portion of the discontinuities in the first nonwoven layer, wherein the second nonwoven layer is attached to the first nonwoven layer such that at least a portion of the second plurality of fibers are in liquid communication with the first nonwoven layer, wherein the first nonwoven layer is hydrophobic and the second nonwoven layer is hydrophilic.
Absorbent article comprising a topsheet/acquisition web laminate
An absorbent article for personal hygiene comprises a longitudinal axis, a transversal axis perpendicular to the longitudinal axis, a topsheet/acquisition web laminate, a liquid impermeable backsheet, and an absorbent core. The absorbent core is located between the topsheet/acquisition web laminate and the backsheet. The topsheet/acquisition web laminate comprises a liquid permeable topsheet and an acquisition web in a face to face relationship. The topsheet/acquisition web laminate comprises three-dimensional protrusions extending from a plane of the topsheet/acquisition web laminate. The acquisition web is a nonwoven fibrous web comprising an upper layer facing towards the topsheet and a lower layer facing towards the absorbent core. The average diameter of the fibers in the upper layer is higher than the average diameter of the fibers in the lower layer.
Methods and tooling for making three-dimensional substrates for absorbent articles
Methods and tooling for making three-dimensional substrates and/or apertured substrates are provided. The three-dimensional substrates and/or apertured substrates may be used in absorbent articles, such as diapers and pants, for example. The methods and tooling may be used on an absorbent article manufacturing line.
URINE COLLECTION SYSTEMS, AND METHODS OF MAKING AND USING THE SAME
Urine collection systems are disclosed. Methods of making and using urine collection systems are also disclosed.
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.
DISPOSABLE ABSORBENT ARTICLE
A material web having a film layer and a nonwoven layer, along with methods of making the material web, are described. The material web has a plurality of micro-deformations and a plurality of macro-deformations, each of the macro-deformations having a distal end, wherein a first portion of macro-deformations has an open or partially open distal end and wherein a second portion of macro-deformations has distal ends which are configured differently than the distal ends of the first portion, and wherein the material web forms a portion of the topsheet.
Method for making hydroformed expanded spun bonded nonwoven web
A method for hydroforming a spun bonded nonwoven web includes applying a plurality of pressurized liquid jets onto an original unexpanded spun bonded nonwoven web having an original loft while the web passes over a forming structure. A plurality of spun bonded fibers in the original unexpanded spun bonded nonwoven web are reoriented from a closely packed substantially horizontal orientation to a more loosely packed orientation with greater vertical spacing between the fibers to produce a hydroformed expanded spun bonded nonwoven web having a loft of at least about 1.3 times greater than the original loft of the original unexpanded spun bonded nonwoven web, and an air permeability of at least about 1.2 times greater than an original air permeability of the original unexpanded spun bonded nonwoven web. The hydroformed expanded spun bonded nonwoven web has a surface with a plurality of protuberances in a pattern corresponding to the pattern of apertures in the forming structure.
