Abstract
An industrial two-layer fabric includes pairs of warps obtained by stacking an upper side warp to be woven with an upper side weft and a lower side warp to be woven with a lower side weft and having, as at least one of the pairs. A pair of binding warps includes warp binding yarns to be woven with both an upper side weft and a lower side weft constitutes a portion of an upper side surface design and a portion of a lower side surface design. In a lower side surface warp design formed by the weaving of a warp binding yarn and a lower side warp with a lower side weft, two or three designs are different from each other, and a weft passes over two warps adjacent to each other and then passes under a plurality of warps to form a long crimp on the lower side surface.
