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.
FORMING STRUCTURE, APPARATUS AND METHOD FOR FORMING A BREATHABLE, LIQUID IMPERMEABLE, APERTURED FORMED FILM AND FILM MANUFACTURED THEREBY
A forming structure includes an outer surface configured to receive a polymer web, an inner surface, a thickness between the outer surface and the inner surface, and a plurality of openings extending through the thickness at an acute angle relative to a plane tangential to the outer surface. Each of the plurality of openings has a shape at the outer surface defined by a first ellipse having a first major axis and a first minor axis and a second ellipse having a second major axis and a second minor axis. The first major axis is substantially parallel to a machine direction and coincides with the second minor axis. The second major axis is substantially parallel to a transverse direction orthogonal to the machine direction and is offset from the first minor axis.
Absorbent articles with indicia and/or color
An absorbent article is disclosed, including a three-dimensional material formed of a liquid permeable topsheet and an acquisition material. The acquisition material is positioned beneath the topsheet, and both may be formed of nonwoven material. The three dimensional material may have two surfaces and a plurality of protrusions extending in a z-direction from one of the surfaces, each protrusion having side walls defining an opening in the other of the surfaces. One of the topsheet and the acquisition material may include fibers spun of polymer resin pigmented with a first color that differs from a second color of fibers of the other of the topsheet and the acquisition material, and the differing colors are visible when viewing a wearer-facing surface of the absorbent article.
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.
Apertured webs and methods for making the same
A 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 of the land areas surround at least some of the apertures. The patterned apertured web has an Effective Open Area in the range of about 5% to about 50%, according to the Aperture Test. The patterned apertured web has a plurality of Interaperture Distances, according to the Aperture Test. The Interaperture Distances have a distribution having a median and a mean. The mean is greater than the median.
Apertured webs and methods for making the same
Patterned apertured webs are provided. The patterned apertured webs include a plurality of land areas and a plurality of apertures defined in the patterned apertured webs. At least some land areas of the plurality of land areas surround at least some apertures of the plurality of apertures. The patterned apertured webs have an Effective Open Area in the range of about 3% to about 30%, according to the Aperture Test.
Porous polyolefin fibers
A polyolefin fiber that is formed by a thermoplastic composition containing a continuous phase that includes a polyolefin matrix polymer and nanoinclusion additive is provided. The nanoinclusion additive is dispersed within the continuous phase as discrete nano-scale phase domains. When drawn, the nano-scale phase domains are able to interact with the matrix in a unique manner to create a network of nanopores.
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 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%.
Three-dimensional substrate comprising a tissue layer
A three-dimensional substrate has a first surface, a second surface, land areas and comprises three-dimensional protrusions extending outward from the second surface of the three-dimensional substrate. The three-dimensional protrusions are surrounded by the land areas. The three-dimensional substrate is a laminate comprising at least two layers in a face to face relationship.
