ABSTRACT:
A fibrous nonwoven fabric of good drapability, comprising geometrically arranged spaced first surface areas of about 0.02 to 0.2 mm.sup.2 in area in which its fibers are chemically or thermally bonded at their intersections, and second area whose junctions are at least partially reopened and in which the bond points are disposed closely adjacent one another is produced by bonding a non-woven fleece chemically or thermally, and then stretching the resulting fabric at spaced areas so as to expand it partially and form areas where the fibers are less or not bonded. Where a chemical binder is used it may be set only partially prior to stretching, setting being completed thereafter.
