Apertured polymeric film webs and absorbent articles using such webs

Methods for making an apertured polymeric film web or a composite structure web are disclosed. These webs may be utilized as a topsheet in an absorbent article and can provide fluid handling and softness benefits.

THREE-DIMENSIONAL SUBSTRATES

A liquid permeable substrate for an absorbent article is disclosed. The substrate includes a first layer including a hydrophobic material and a second layer including a hydrophilic material. The first layer is joined to the second layer. The substrate includes a plurality of recesses, a plurality of projections, and a plurality of land areas. The land areas surround at least a majority of the plurality of projections and a plurality of the recesses. The plurality of recesses, the plurality of projections, and the plurality of land areas together form a first three-dimensional surface on a first side of the substrate and a second three-dimensional surface on a second side of the substrate. The substrate has an overall z-directional height in the range of about 1000 m to about 6000 m according to the Overall Substrate Height Test.

Treated three-dimensional apertured liners

A bodyside liner material for use in disposable absorbent personal care products has an average material plane and includes a plurality of raised areas extending in a z-direction from the average material plane; a plurality of apertures through the liner material; a hydrophobic treatment agent disposed on the raised areas; and a plurality of land areas disposed between the raised areas, wherein the land areas are hydrophilic. The bodyside liner material can also include a plurality of raised areas extending in a z-direction from the average material plane; a plurality of depressed areas alternating with the plurality of raised areas, wherein the depressed areas extend in the opposite z-direction from the average material plane, and wherein the depressed areas are hydrophilic; a plurality of apertures through the liner material, wherein the apertures are disposed only in the depressions; and a hydrophobic treatment agent disposed on the raised areas.

Fluid distribution material for absorbent articles

A fluid distribution material for use in an absorbent article includes a formed film layer having first and second sides and a basis weight of between about 10 gsm and about 25 gsm, and a nonwoven layer having a basis weight of between about 10 gsm and about 15 gsm and laminated to the formed film layer. The formed film layer includes a plurality of apertured protuberances arranged in a pattern having 10 to 40 protuberances per linear inch. Each of the protuberances includes a continuous sidewall extending from the first side, and the second side has a plurality of apertures aligned with the plurality of protuberances, and land areas in between the apertures. The nonwoven layer includes a plurality of fibers attached to the formed film layer at the land areas. The material has a rewet value of less than 0.075 grams in accordance with the Rewet Test Method.

Process for producing a web substrate having indicia disposed thereon and elastic-like behavior imparted thereto

A process for providing indicia and an elastic-like behavior to a web substrate is disclosed. The process comprises the steps of: providing a web substrate; printing indicia on the web substrate; and, providing the web substrate with a plurality of first regions and a plurality of second regions comprising the same material composition. A portion of the first regions extend in a first direction while the remainder of the first regions extend in a second direction perpendicular to the first direction to intersect one another. The first regions form a boundary completely surrounding the second regions. The second regions comprise a plurality of raised rib-like elements. The first regions undergo a molecular level and geometric deformation and the second regions initially undergo a substantially geometric deformation when the web material is subjected to an applied elongation along at least one axis.
