Abstract
Abstract A nonwoven fabric having a plurality of patterns of groups of fiber segments that alternate and extend throughout the fabric. One of the patterns, disposed in discontinuous portions of the fabric, consists of fiber segments which are interentangled and in helter-skelter arrangement and protrude out of the plane of the fabric. These discontinuous portions of the fabric are interconnected by a plurality of yarn-like bundles of fiber segments which define apertures or holes or other areas of low fiber density in continuous portions of the fabric to form a second pattern.
