Patent ID: 7412991

Claim:
An industrial two-layer fabric comprising: an upper surface side fabric having an upper surface side warp and an upper surface side weft; and a lower surface side fabric having a lower surface side warp and a lower surface side weft, the upper surface side warp and lower surface side warp being arranged vertically and constituting a pair, and the upper surface side fabric and lower surface side fabric being bound with a yarn in a warp direction, wherein: the lower surface side fabric is made of a first design in which either one of a first warp binding yarn and a second warp binding yarn constituting a pair to be woven with an upper surface side weft and a lower surface side weft, passes under one lower surface side weft and then passes over a plurality of lower surface side wefts; the lower surface side warp adjacent to the one of the first and second warp binding yarns passes over and under the same lower surface side wefts over and under which the one of the first and second warp binding yarns passes; the first design of a set of the lower surface side warp and the one of the first and second warp binding yarns which are adjacent to each other, is shifted with respect to another different set of two warps adjacent to each other, and the sets being arranged sequentially to form a complete design of the lower surface side fabric; and a lower surface side weft has a second design in which the weft passes over two successive warps and then passes under a plurality of warps to form a long crimp on the lower surface side surface.
