Abstract

PURPOSE: To obtain a soft woven fabric having excellent spun-toned touch of feel, stretchability and recoverability, and composed of bulky yarns which are produced by interlacing filament yarns of inelastic polymer as sheath yarns on core yarns consisting of sheath/core type conjugate fibers each composed of elastic polymer as the core component and inelastic polymer as the sheath component. CONSTITUTION: This woven fabric >=2% in lateral stretch rate is obtained by the following process: multifilament yarns Yc consisting of sheath/core type conjugated fibers each composed of elastic polymer as the core component and inelastic polymer as the sheath component are fed in an overfeed condition from a package 1 via a feed roller 3; concurrently, multifilament yarns Ys of inelastic polymer are fed in an overfeed rate greater than that for the filament yarns Yc from another package 2 via a feed roller 4; subsequently, both the multifilament yarns Yc, Ys are imparted with water using a relevant roller 5 and then subjected to turbulent flow jet treatment using a pressurized air nozzle 6 to mutually interlace them, and then wound with a winder 8 into a package, thereby obtaining bulky yarns Y with the sheath yarns Ys interlaced on the core yarns Yc so as to form loops and/or slacks; finally, the bulky yarns Y are subjected to weaving operation.
