ABSTRACT:
Process and apparatus for producing apertured or non-apertured nonwoven fabric wherein fibrous web is introduced onto support means and treated with high velocity water streams jetted from above. The non-apertured nonwoven fabric may be produced by fiber entangling treatment on a smooth surfaced plate including a plurality of drainage holes as first support means or by further fiber entangling treatment performed on water impermeable second support means after the fiber entangling treatment performed on the first support means. The apertured nonwoven fabric may be produced by, after the fiber entangling treatment on the first support means, using, instead of the second support means, another second support means consisting of a smooth surfaced plate provided with a plurality of projections and drainage holes so that individual fibers of the fibrous web are deflected by water streams jetted from above the fibrous web aside towards zones of the surface defined by each pair of adjacent projections while entangling these individual fibers with each other.
