A method of producing a fluid-pervious fabric for imparting a pattern to a fibre web, wherein said fabric (101; 201) is brought into a press nip (105) between a rotating embossing roll (106) having embossing means (107) on its outer surface and a support (108). Said fabric comprises at least two zones as seen in the z-direction, a first zone (101a;201a) and a second zone (101b,201b), wherein said first zone comprises a first polymer material having a first glass transition temperature and said second zone comprises a second polymer material having a second glass transition temperature which is higher than that of said first polymer material. The fluid-pervious fabric (101;201) is heated to a temperature close to or slightly below the first glass transition temperature and below the second glass transition temperature before and/or during passage through said press nip (105), wherein the embossing means (107) produces impressions (110, 210) in the surface (102;202) of the fabric, said impressions extending into said said first zone (101a;201a) but not or only slightly extending into said second zone (101b;201b). <IMAGE> |
