Abstract
Abstract A nonwoven fabric having a plurality of patterns of groups of fiber segments that alternate and extend throughout the fabric. The first pattern is of yarn-like bundles of fiber segments which define holes or apertures or other areas of low fiber density located in first discontinuous portions of the fabric. These discontinuous portions of the fabric are interconnected by ribbon-like groups of aligned fiber segments that form a second pattern in second discontinuous portions of the fabric.
