ABSTRACT:
The disclosure is of a fabric adapted as clothing for a papermaking machine. The fabric, which may be made endless, is useful to make dryer felts, wet felts and forming wires. The fabric of the invention comprises a plurality of crosswise yarns disposed in a plurality of separate layers, each layer being on a plane parallel to the crosswise plane of the fabric. A plurality of lengthwise yarns is interwoven with the crosswise yarns and binds the layers of crosswise yarns together to form a multilayer fabric. Structurally, the crosswise yarns in a given layer are separated from the adjacent crosswise yarns in adjacent layers at points along their length by void spaces within the body of the woven fabric. A synthetic, polymeric, thermoplastic resin foam fills, at least partially, the void spaces to control the void volume in the fabric of the invention.
