Industrial two-layer fabric

An industrial two-layer fabric comprising an upper side layer formed by weaving upper side warps with upper side wefts and a lower side layer formed by weaving lower side warps with lower side wefts, the upper side layer and the lower side layer being bound with binding yarns, wherein:

• each of the lower side wefts passes over three successive lower side warps and then passes under two or more lower side warps thereby forming a lower-side-weft design that includes a lower-side-weft long crimp;
• a complete design in the lower side layer is formed by arranging the lower side wefts adjacent to each other while repeatedly shifting the lower-side-weft design in accordance with one of the following shifting patterns:
• (1) shifting by three warps,
• (2) shifting by four warps,
• (3) shifting by five warps,
• (4) shifting by one warp and then four warps,
• (5) shifting by three warps and then four warps,
• (6) shifting by two warps and then five warps,
• (7) shifting by one warp and then six warps, and
• (8) shifting by one warp, four warps, five warps, and then four warps;
• and
• the lower-side-weft long crimp formed in the lower side layer has a rectangular shape.
