Stretchable woven fabric and fiber product

Abstract

To provide a novel stretchable woven fabric and a fiber product which have both wearing comfort due to lightweight and multidirectional stretchability and natural fiber tone, a stretchable woven fabric includes: stretchable fibers in which different two-component polymers are formed into a side-by-side shape or an eccentric core-sheath shape, in both a warp and a weft; and composite textured yarn obtained by combining the stretchable fibers and a multifilament fiber dissimilar to the stretchable fibers, in either one or both of the warp and the weft, in which the different two-component polymers are a combination selected from a combination of dissimilar polymers having different structures and a combination of polymers having different intrinsic viscosities, the polymers are a polyester-based polymer selected from polyethylene terephthalate and polybutylene terephthalate, and the stretchable woven fabric has a basis weight of 100 g/m 2 to 200 g/m 2 and is suitable for a fiber.
