A nonwoven fabric patterned with apertures comprising nonwoven fabric areas into which individual fibers are gathered and entangled together and continuously from which said fibers are branched, and circular or elliptical apertures defined by said areas in a regular pattern. Such nonwoven fabric is produced by treating a fibrous web on a support having thereon a plurality of projections distributed at predetermined intervals with a high speed water jet. |
