  • Publication number: 20120219751
    Abstract: A pile fabric whose pile fibers are prevented from falling off without impairing the texture by fusing only a specific area of the pile fabric. The pile fabric has a ground structure and pile fibers that are intertwined with ground yarns and napped on a front surface of the ground structure. The pile fibers including acrylic fibers and/or acrylic-based fibers and have a softening point lower than a softening point of the ground structure fibers, and are intertwined with the ground yarns. At least part of the pile fibers located outside of the ground yarns are fused but the pile fibers napped on the front surface of the ground structure are not fused. A method of producing a pile fabric includes a contact heating/pressurization step at a temperature equal to or higher than the softening point of the pile fibers and lower than the softening point of the ground structure fibers.
