<p>The invention relates to a press felt for the transportation of a web and for the dewatering thereof in a press part of a paper machine. The press felt comprises at least one needled flock layer formed by fibres. In order to eliminate the re-wetting and the blow effect, a surface layer is formed on or partially within the flock layer at least on one side of the felt. The permeability of the surface layer is substantially lower than that of the rest of the felt beneath the surface layer. The surface layer can be formed by a plastic material applied on the flock layer.</p> |
