Abstract: 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 “funnels” 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.
