<p>A web of fabric (1) with a carrier (2) has an externally-even plastic layer (5, 6) at least on one side, traversed by transfer channels. According to the invention, the external side (7, 8) of the plastic layer (5, 6) also has impressions (9) between the openings of the transfer channels which are at least partly connected with one another and with the transfer channels. During the production of the fabric web, soluble particles are applied to the external side (7, 8) of the plastic layer (5, 6) during or after the production of the plastic layer (5, 6) and then pressed into the plastic layer (5, 6). These soluble particles may then be extracted by a solvent to which the fabric web (1) is resistant.</p> |
