Patent ID: 8809211

Claim:
An industrial two-layer fabric comprising: an upper side fabric comprising upper side warps and upper side wefts, each of the upper side warps forms an upper side warp design; and a lower side fabric comprising lower side warps and lower side wefts; wherein the upper side warps comprise a first warp set and a second warp set, the first warp set contains adjacent two of the upper side warps and a first one of the lower side warps, the adjacent two of the upper side warps are woven with the same upper side wefts, the first one of the lower side warps functions as a warp binding yarn and is woven with an upper side weft and a lower side weft thereby binds the upper side fabric and the lower side fabric, the second warp set contains one of the upper side warps, the first warp set and the second warp set are placed alternately; wherein, at a position where the warp binding yarn passes above one of the upper side wefts, the warp binding yarn is placed between the adjacent two upper side warps of the first warp set, the adjacent two upper side warps at the position pass below the same one of the upper side wefts, whereby the adjacent two upper side warps and the warp binding yarn of the first warp set form the upper side warp design.
