    摘要： An anti-rewet press fabric for paper and board machines includes a barrier layer such that during compression in the press nip, the water is forced through the barrier layer, but is prevented from flowing back to the paper web during expansion. The barrier layer comprises a continuous material possessing, for example square, rectangular, tetrahedral, circular or oblong conical inclusions with a smaller opening on the bottom than on the top of the structure. Each of these nullfunnelsnull effectively constitutes a one-way valve and creates a vacuum to prevent re-absorption of water by the paper sheet. Under pressure, the structure of the barrier layer allows water to flow into the cones and out of the smaller opening in the bottom. Upon expansion, the smaller opening in the bottom of the structure restricts backward water flow and creates a vacuum on the other side. The vacuum increases water retention in the press fabric and prevents rewetting of the paper sheet. Another embodiment of the invention is described herein, wherein the barrier layer exists as a separate fabric fed through a press section. In this embodiment, the nullseparate fabricnull can just be the nullconical inclusion sheetnull itself. That is, the sheet itself constitutes an inventive belt having anti-rewet properties.

    摘要： A method is disclosed for the production of a textile surface construction of at least one base layer and mesh-needled to the base layer a useful surface layer showing an optically non-uniform, substantially rapport-free upper side. Apart from staple fibers, the upper side contains a multitude of stochastically distributed fiber elements with a pre-selected, possible variable geometric form, which distinguish from the staple fibers in terms of color and/or fiber characteristics. In addition, the present invention relates to a textile surface construction which is produced by such a method.
