ABSTRACT:
A nonwoven fabric with a layer of fibers of staple length arranged in a predetermined pattern of fiber bundles defining areas of low fiber density and having one surface free of fiber ends and the other having a substantial number of fiber ends bonded with an adhesive to provide strength and stability. The fabric is made by supporting a layer of fibers of staple length on a foraminous support member and applying fiber moving forces to a layer to form areas of low fiber density and fiber bundles while simultaneously causing the ends of fibers to protrude through the opening of the foraminous support. The layer is removed from the support and the fiber ends bonded together to produce my novel nonwoven fabric.
