Abstract
A web of non woven textile fabric is fed on a porous belt into the nip between the belt and a rotating porous drum to compress the web within the nip. A curtain of water is passed through the web while it is in the nip into the drum and a vacuum is drawn on the drum to remove the water. The web, after passing the nip remains upon the drum and is subject to one or more high pressure jets of water to entangle the web fibers.
