To provide a double cylindrical woven fabric sufficiently improved in withstanding pressure and strength by weaving inside and outside double cylindrical woven fabrics and connecting the inside and outside cylindrical woven fabrics as one body.
In an outside cylindrical woven fabric 2 comprising plural warps 4a positioned cylindrically and wefts 5a crossing with the warps 4a and woven spirally, an inside cylindrical woven fabric 3 similarly comprising plural warps 4b and wefts 5b is positioned, and the outside woven fabric 2 and the inside woven fabric 3 are connected each other. Thereby, as the outside cylindrical woven fabric and the inside woven fabric are lapped, so strength is large, and, as the two layer cylindrical woven fabrics are monolithically connected, so displacement does not occur and withstanding pressure and strength of the two layered cylindrical woven fabric are sufficiently high.
