Title:
STRETCHABLE FABRIC, AND MANUFACTURING METHOD AND MANUFACTURING DEVICE FOR SAME
Document Type and Number:
WIPO Patent Application WO/2019/139177
Kind Code:
A1
Abstract:
Provided are a stretchable fabric, and a manufacturing method and a manufacturing device for the same, the stretchable fabric exhibiting high stretchability and stretch recovery, as well as a low washing machine shrinkage ratio. In this stretchable fabric, the weft comprises stretchable composite yarns 1 comprising a stretchable core yarn 10 and a sheath yarn 11 that covers the same, and the warp comprises chemical fiber yarns and/or natural fiber yarns. Each stretchable composite yarn 1 is a single covered yarn, and the number of times the sheath yarn 11 is wrapped around the core yarn per meter thereof is 1,000-2,500 T/m. During weaving, the stretch ratio of the composite yarns in the fabric is maintained to at most 1.3 times that of the composite yarns 1 before weaving, which serve as the reference. If a compressed air flow is blown in a direction substantially opposite to the threading direction of the composite yarns 1 during weaving, the tensile force on the composite yarns 1 during weaving is reduced and the extension of the composite yarns 1 is inhibited, thereby making it possible to maintain a low degree of stretching of the composite yarns 1 forming the weft of the fabric.
