A double fabric is provided to suppress the generation of creases, by swelling air remaining between two fabric layers through heat in a high-temperature hardening process, after coating a rear surface of the double fabric so as to swell the double fabric. A fabric comprises an expansion portion(10) including two fabric layers separated from each other and simultaneously woven by using a weaving machine, and a connection portion(30) for partially connecting two fabric layers to seal and define the expansion portion. The fabric further comprises a normal structure and an abnormal structure. The normal structure is different from the abnormal structure in a difference of air permeability, wherein the difference of air permeability is equal to or more than 1 ft^3/min. |
