Abstract (en)

Polyurethane elastic yarns meeting the following conditions: (1) the angle corresponding to the half-height width of maximum peak intensity in an azimuthal scanning in the measurement of small-angle X-ray scattering is 60 DEG or greater; (2) the angle corresponding to the half-height width in the equatorial direction in the measurement of small-angle X-ray scattering is 2.5 DEG or smaller; and (3) the temperature at the peak of maximum shrinkage stress in the measurement of thermal stress is 135 DEG C or lower; and stretch fabrics which are prepared by weaving or knitting of the above polyurethane elastic yarns in mixture with thermoplastic synthetic fibers, natural fibers, or regenerated fibers.
