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 μm to about 6000 μm according to the Overall Substrate Height Test.

The substrate has an overall z-directional height in the range of about 1000 &#x3bc;m to about 6000 &#x3bc;m according to the Overall Substrate Height Test.

Substrate with a pattern

A treated substrate with improved availability of a beneficial component for transfer to a target surface and methods for making the same are described. The substrate has a contacting surface with a beneficial component that is transferred from the contacting surface to a target surface during use of the article. The beneficial component is applied to the article in such a way as to 'Top-Bias' the component on or near the contacting surface of the article.

Top-biased beneficial components on substrates

The present invention is directed to a method and apparatus for making nanofiber webs, wherein a source of process air is utilized to affect the spray pattern and quality of fibrillated material expressed from a die assembly including a multi-fluid opening. Appropriately, the aforementioned process air is defined herein as an alternate or ancillary air source apart from primary process air, which primary air is simultaneously supplied with the molten polymeric material to the fiber forming multi-fluid opening. The ancillary air source of the invention is further distinct from secondary air, which is also known in the art as quenching air. The ancillary air can be described as a continuous fluid curtain of shielding or shaping air.
