  • Publication number: 20230264647
    Abstract: Object: Conventional woven fabrics mounted on a loom have a fabric length difference between the center portion and the sides of the woven fabric, which increases the flaring rate. In the scouring shrinkage step, yarns shrink and the crimp ratio is changed, which further increases flaring. Means for achieving object: The use of a bar temple with a ring function in the weaving process reduces protrusions. Further, by setting the boiling-water shrinkage rate of incorporated additional yarn lower than that of base yarn, the shrinkage of the sides of the fabric can be efficiently suppressed.
