    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.

    摘要: An aspect of the present invention is a glove including: a glove main body knitted with a yarn made of fiber, the glove main body including: a main body portion; five finger-receiving portions each having a bottomed cylindrical shape; and a cylindrical cuff portion, wherein in at least a part of a palm part, the main body portion has a repeating structure of: a strip-shaped electrically conductive part containing an electrically conductive yarn; and a strip-shaped electrically non-conductive part not containing the electrically conductive yarn, a ratio of the number of courses of the electrically conductive part to the number of courses of the electrically non-conductive part, the electrically conductive part and the electrically non-conductive part being adjacent to each other, is no less than 1:2 and no greater than 1:6, the electrically conductive part is constituted by plating knitting of the electrically conductive yarn and an electrically non-conductive plating yarn, a fineness ratio of the electrically conductive yarn to the plating yarn is no less than 1:0.5 and no greater than 1:2, and a fineness ratio of an electrically non-conductive yarn, which constitutes the electrically non-conductive part, to the electrically conductive yarn contained in the electrically conductive part is no less than 1:0.4 and no greater than 1:1.

    摘要: A fabric woven by imitating warp knitting, which includes first warps, second warps, first wefts, and second wefts; the first warps and the first wefts are interlaced to form the face of the fabric, and the second warps and the second wefts are interlaced to form the back of the fabric; and 7 to 15 weft interlacing points are arranged between each two adjacent groups of warp interlacing points on the second warps. The fabric woven by imitating warp knitting in the present invention has not only the appearance style of woven fabrics but also the characteristics of good air permeability and good hand feel of warp-knitted fabrics.
