FIELD: textile; paper.
SUBSTANCE: invention concerns fabric for press part of paper-making machines. Layer includes multiple contact sites, multiple fluted sites and multiple perforation orifices. Orifices run from top to bottom surface of the layer. Flutes maintain flow diffusion of the surface of perforated layer to reduce pressure release are the reverse side of the layer, thus reducing particle transfer.
EFFECT: prevention or reduction of light and dark area pattern formation by particles on paper sheet obtained, quality improvement.
