Patent attributes
In an industrial two-layer fabric, 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. 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.
