Document Type and Number:
WIPO Patent Application WO/2023/132242
Kind Code:
A1
Abstract:
In order to provide an unprecedented stretchable woven fabric and fiber product that have natural fiber-like properties and are comfortable to wear due to being lightweight and having multi-directional stretching properties, a stretchable woven fabric according to the present invention includes stretchable fibers, in which two differing component polymers are formed in a side-by-side shape or an eccentric core-sheath shape, in both the warp and the weft and includes a composite textured yarn, which is obtained by combining the stretchable fibers and multifilament fibers that are dissimilar to the stretchable fibers, in either one or both of the warp and the weft, wherein: the two differing component polymers are a combination selected from a combination of dissimilar polymers having differing structures and a combination of polymers having differing intrinsic viscosities; and the polymers are polyester-based polymers selected from polyethylene terephthalate and polybutylene terephthalate, have a basis weight of 100-200 g/m2, and are suitable in fiber products.
