Abstract:
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.
Abstract:
Methods for making tip bonded formed laminates are made from multiple layers of formed substrates made from films which are bonded together at the tips of their formed protrusions. Tip bonded laminates can be designed with greater resistance to bending, improved resilience to compression, and can be patterned for directionally oriented responses to tensile loads. Also, tip bonded formed laminates made from multiple layers of formed substrates can use their layered structure to provide better aesthetics as well as better physical properties such as improved puncture resistance. Tip bonded formed laminates can be configured with thicker portions and designed patterns, which are appealing to consumers. A tip bonded formed laminate can be made from two or more formed substrates and can be used instead of a single, thick, unformed, substrate, so the laminate can use about the same amount of material, while still providing surprising functional benefits.

A tip bonded formed laminate can be made from two or more formed substrates and can be used instead of a single, thick, unformed, substrate, so the laminate can use about the same amount of material, while still providing surprising functional benefits. Tip bonded formed laminates can provide these benefits without relying on more expensive polymers and/or high concentrations of additives and offer significant improvements at a reasonable cost, when compared with unformed, single layer substrates.
Abstract:
A method of forming a three-dimensional laminate for an absorbent article is provided. The method comprises providing a first nonwoven layer, providing a second nonwoven layer, and applying a pre-strain force to the first nonwoven layer or to the second nonwoven layer. The method comprises joining the first nonwoven layer to the second nonwoven layer while the first nonwoven layer or the second nonwoven layer is in a pre-strained condition, and releasing the pre-strain force to form the three-dimensional laminate.
Abstract:
A disposable absorbent article having a topsheet, a backsheet, and an absorbent core disposed therebetween is described. The topsheet includes a plurality of apertures arranged in a first zone and a first plurality of structures which are disposed adjacent to the first plurality of apertures. The plurality of apertures have an Effective Aperture Area of from between 0.5 mm2 to about 8 mm2 as measured by the Aperture/Feret Angle test as described herein, and the topsheet has a top layer and a lower layer, wherein the top layer is more hydrophobic than the lower layer.
Abstract:
A composite sheet that includes a first sheet and a second sheet is disclosed. The first and second sheets are bonded to each other at a number of spaced apart discrete inter-sheet bond locations. The first sheet is a nonwoven material that has discrete three-dimensional deformations therein forming protrusions that extend outward from the first surface of the first sheet to their distal ends and wide base openings adjacent to the second surface of the first sheet. The second sheet is a generally planar sheet that contacts the distal ends of the protrusions on the first sheet. The second sheet is bonded to the first sheet at spaced apart inter-sheet bond locations where the first region of the first sheet contacts the second sheet.
Abstract:
Nonwoven materials having discrete three-dimensional deformations therein forming protrusions that extend outward from the first surface of the nonwoven material and wide base openings adjacent to the second surface of the nonwoven material are disclosed. At least some of the three-dimensional deformations are configured to collapse in a controlled manner when compressive forces are applied on the nonwoven material.
Abstract:
Disclosed herein are textured nonwoven webs suitable for use in disposable absorbent articles. The textured nonwoven webs have a generally planar first region and a plurality of integrally formed discrete second regions. The textured nonwoven webs also have at least one composition disposed on at least one of the first region or the plurality of discrete second regions.
Abstract:
A method of forming a composite sheet that is made of a first sheet and a second sheet is disclosed. The first and second sheets are bonded to each other at a number of spaced apart discrete inter-sheet bond locations. The method involves mechanically deforming a precursor nonwoven web to form a first web with deformations therein. The deformations form protrusions that extend outward from the first surface of the first web and openings in the other surface of the web. The method involves feeding the first nonwoven web with the deformations therein into a bonding nip where portions of the first region of the first web outside of the deformations are bonded to the second web to form a base-bonded composite web.
Abstract:
Nonwoven materials having discrete three-dimensional deformations therein forming protrusions that extend outward from the first surface of the nonwoven material and wide base openings adjacent to the second surface of the nonwoven material are disclosed. The nonwoven materials include multiple fibers that extend from the base of the protrusions to the distal end of the protrusions, and contribute to form a portion of the sides and cap of a protrusion. Such fibers may at least substantially surround the sides of the protrusions.
