Abstract:

An object of the present invention is to provide an elastic woven fabric which has not only excellent elongation properties and elongation recovery properties but also a low washing shrinkage rate, and its producing method and producing apparatus.An elastic woven fabric comprises weft and warp yarns, the weft yarns including a plurality of elastic composite yarns 1 each of which comprises an elastic core yarn 10 and a sheath yarn 11 covering the elastic core yarn 10, and the warp yarns including a plurality of chemical fiber yarns and/or a plurality of natural fiber yarns,wherein each of the elastic composite yarns 1 is in a form of a singly-covered yarn, a number of turns of the sheath yarn 11 per 1 meter of the core yarn 10 being in a range of 1,000 to 2,500 T/m,and wherein a stretching magnification ratio of each of the composite yarns 1 in a weaving process is retained equal to or less than 1.30 folds based on the composite yarn 1 before weaving.By blowing a compressed air flow in a direction substantially opposite to a feed direction of the composite yarn 1 when weaving, it is possible to reduce a tensile force applied to the composite yarn 1 to decrease stretching of the composite yarn 1 in a weaving process, and therefore the stretching of the composite yarns 1 constituting the weft yarns of the elastic woven fabric can be kept low.
