    摘要: An elastic woven fabric comprising weft and warp yarns, the weft yarns including elastic composite yarns each of which comprises an elastic core yarn and a sheath yarn covering the elastic core yarn, and the warp yarns including chemical fiber yarns and/or natural fiber yarns. Each of the elastic composite yarns is in a form of a singly-covered yarn in which the elastic core yarn is covered by a single layer of the sheath yarn helicoidally wound around a periphery of the elastic core yarn, a number of turns of the sheath yarn per 1 meter of the elastic core yarn being in a range of 1,000 to 2,500 T/m. A stretching magnification ratio of each of the elastic composite yarns, in the elastic woven fabric in a weaving process, is retained equal to or less than 1.30 folds based on the elastic composite yarn before weaving.
