Abstract
A nonwoven substrate includes individual fibers each having a fiber surface and a fiber diameter, wherein a portion of the individual fibers include a micro-embossed pattern, and wherein the micro-embossed pattern includes pattern elements equal to or smaller than the fiber diameter. The pattern elements can be recessed into and/or extend out of the fiber surface, and the nonwoven substrate can include polypropylene or polyethylene. A disposable absorbent article includes a nonwoven substrate having individual fibers each having a fiber surface and a fiber diameter, wherein a portion of the individual fibers include a micro-embossed pattern, and wherein the micro-embossed pattern includes pattern elements equal to or smaller than the fiber diameter.
