  • Patent number: 7306014
    Abstract: In a lower surface side layer of an industrial two-layer fabric, warps are formed by sequentially arranging a repeating design unit, in which one warp passes over six successive lower surface side wefts, passes under one lower surface side weft, passes over two lower surface side wefts, and passes under one lower surface side weft while shifting the design by three lower surface side wefts. Two adjacent lower surface side warps simultaneously weave therein, from the lower surface side, one lower surface side weft, whereby the lower surface side weft passes over two lower surface side warps and then passes under eight lower surface side warps to form a weft long crimp corresponding to eight lower surface side warps on the lower surface side surface.

    Abstract: In a repeating unit of a two-layer fabric, a first upper surface side warp forms a first upper surface side warp design. A second upper surface side warp forms a latent portion in which the second upper surface side warp passes between the two layers of the fabric. A first lower warp binding yarn and a second lower warp binding yarn form first and second knuckles respectively by passing over one or two upper surface side wefts at a position not adjacent to two knuckles of the second upper surface side warp in the latent portion. The first and second knuckles are formed at different positions. The first lower warp binding yarn, second upper surface side warp and second lower warp binding yarn cooperatively form a second upper surface side warp design similar to the first upper surface side warp design.

  • Patent number: 6510873
    Abstract: A press fabric for a pulp machine is a weft-abrading type fabric manufactured by weaving a warp monofilament and a bundled yarn. The bundled yarn has fine water-sucking spaces formed between raw filaments of a small diameter by bundling up the raw filaments. Monofilaments may also be used as the wefts in combination with the bundled yarns. The bundled yarn forms the most protuberant crimp to the surface of the fabric which results in improved water-sucking ability, washing ability, showering resistance, and abrasion resistance.
