Abstract: An absorbent article having a liquid permeable topsheet, a liquid impermeable backsheet, and an absorbent layer enveloped therebetween is disclosed. The topsheet comprises a fibrous nonwoven material and has an upper topsheet surface and a lower topsheet surface. The lower topsheet surface exhibits a lower topsheet surface Sdc less than 0.350 mm, and the upper topsheet surface exhibits an upper topsheet surface Sdc that is greater than the lower topsheet surface Sdc. Additionally, or alternatively, the lower topsheet surface exhibits a lower topsheet surface Sdr % less than 0.80; and the upper topsheet surface exhibits an upper topsheet surface Sdr % that is greater than the lower topsheet surface Sdr %. The absorbent layer comprises a layer of open-cell foam having an upper foam surface that is in direct facing contact with the lower topsheet surface.

Abstract: Disclosed is a feminine hygiene pad with an absorbent system including: an absorbent foam layer having a wearer-facing surface and an outward-facing surface, having a plurality of apertures providing z-direction passageways from the wearer-facing surface to the outward-facing surface; and a porous spacer layer beneath the foam layer and underlying a majority of openings of the apertures in an outward-facing surface of the foam layer. The spacer layer functions to provide structure, beneath the absorbent foam layer, that holds open a desired amount of unoccupied space between the absorbent layer and a backsheet of the pad, into which unabsorbed menstrual fluid may flow and temporarily reside, during the time required for the absorbent layer to effectively imbibe the fluid.

Abstract: A process for deforming a web is disclosed. The steps include forming a plurality of microscopic aberrations in a first layer and/or second layer of a precursor web. The microscopic aberrations comprising sidewalls and an aperture disposed at a distal end of the sidewalls. The first layer extends laterally outboard more than the second layer. The precursor web is advanced to a forming unit. The plurality of macroscopic features is simultaneously formed in the precursor web, including first and second features; the first features are disposed in an area of overlap between the first and second layer; the second features are disposed in an area laterally outboard of the second layer; the microscopic aberrations extend in a first direction from the precursor web; the first and second features extend in a second direction from the precursor web; and wherein the first direction is opposite the second direction.

Abstract: Methods for deforming a multilayer web are disclosed. Steps of the method include: supplying a first layer of a precursor web; supplying a second layer of the precursor web onto at least the first area of the first layer; forming a plurality of first features and a plurality of second features in the precursor web. The plurality of first features are apertures formed in a first area of the precursor web, and the plurality of second features are formed in a second area of the precursor web in a positive and/or negative Z-direction. The plurality of first features and the plurality of second features are formed simultaneously.

Abstract: Included are systems and methods for material modeling and prediction. Some systems and methods include determining test data for a test material. The test material may exhibit a plurality of interrelated material behaviors and the test data may relate to the plurality of interrelated material behaviors. Additionally, some systems and methods include providing the test data to a user, receiving a process from the user for decoupling at least two of the plurality of interrelated material behaviors, and, in response to receiving the process for decoupling at least two of the plurality of interrelated material behaviors, fitting a plurality of modules to simulate the test material.
