<p>A paper-making press felt (1) comprises a base (2) made of ground fabrics (A, B); and a second ground fabric of the ground fabrics, which is arranged next to a first ground fabric arranged nearest to a surface (4) of the felt, on which a wet paper sheet is placed. It is a structure, which has air permeability lower than that of the first ground fabric. A paper-making press felt comprises a base, and a batt layer(s) (3) laminated on the base. The base is made of ground fabrics; and a second ground fabric of the ground fabrics, which is arranged next to a first ground fabric arranged nearest to a surface of the felt, on which a wet paper sheet is placed. It is a structure, which has an air permeability lower than that of the first ground fabric, and which such that the movement of water from the second to the first ground fabric is regulated by the difference in air permeability between the first and second ground fabrics, to prevent re-wetting of the paper sheet as the press felt leaves a nip of a press.</p> |
