Industrial two-layer fabric

An industrial two-layer fabric obtained by weaving an upper surface side layer made of upper surface side warps and upper surface side wefts and a running surface side layer made of running surface side warps and running surface side wefts by binding yarns, characterized in that the running surface side wefts constituting the running surface side layer each has a design in which the running surface side weft passes over a running surface side warp, passes under two successive running surface side warps, passes over a running surface side warp and passes under at least four successive running surface side warps, thereby forming a long crimp of the weft on the running surface side surface;

• a running surface side weft adjacent to the above-described weft or adjacent to the above-described weft with one weft sandwiched therebetween is arranged with a design obtained by shifting the design of the above-described weft by two running surface side warps;
• and the design of the running surface side warps is formed of a portion passing under a running surface side weft and a portion passing over at least two running surface side wefts.
