Abstract
A nonwoven fabric of entangled fibers defining a predetermined pattern of openings with the fabric having excellent draping characteristics.
Claims5
A nonwoven fabric formed on a topographically configured support member having a plurality of raised, three-dimensional areas and a plurality of holes between said three-dimensional areas and extending through said support member, said fabric having an upper surface facing away from said support member when said fabric is formed and a lower surface supported on the top of said three dimensional areas when said fabric is formed, said fabric comprising a plurality of fibers disposed between said surfaces, said fibers being rearranged by the application of fluid under pressure to the fabric upper surface and said fibers being intertwined and interentangled with adjacent fibers to define a pattern of openings extending through said fabric, a portion of said openings having a fiber segment loop disposed therein, said loop comprising a plurality of substantially parallel fiber segments in the shape of U with the open inside surface of the base of the U directed towards said lower surface of said fabric and the outside surface of the base of the U directed towards said upper surface of said fabric, said parallel fiber segments being arranged generally transversely of the thickness of said fabric, said fabric having a drape index in all directions of the fabric of at least about 80 degrees.
