  • Publication number: 20180228225
    Abstract: Provided is a garment that has an antistatic capability and exhibits washing durability without, when producing a woven or knitted fabric, using a conductive fiber at a part that becomes a wearing part of the woven or knitted fabric, and without applying an antistatic treatment to the woven or knitted fabric, but rather by incorporating a conductive fiber into a sewing thread. The garment according to the present invention has a conductive fiber incorporated in a sewing thread (linking thread), and has a frictional charge amount of 0.8 ?C or less per garment. The garment preferably has an electric resistance value of 1×104?-5×108? per 1 cm length of the conductive fiber in a fiber axis direction thereof, and the sewing thread preferably includes the conductive fiber in an amount of 30-100 mass %.

  • Publication number: 20170044693
    Abstract: Provided are: acrylic fibers having 2-7% boiling water shrinkage and formed by the side-by-side conjugation of a copolymer A, which contains 5-10 mass % of an unsaturated monomer that can form a copolymer with acrylonitrile units, and a copolymer B, which contains 2-5 mass % of unsaturated monomer units that can form a copolymer with acrylonitrile units and 0.2-1.5 mass % of sulfonic acid group-containing monomer units; a method for manufacturing said fibers; a spun yarn containing said fibers; and a knitted fabric obtained from said spun yarn. The single fiber fineness of the heat-treated acrylic fibers is 1.7-6.6 dtex, the bulkiness is at least 380 cm3/g, the percentage of crimp is at least 15%, and the product (DKSDKE) of the knot strength (cN/dtex) and the knot elongation (%) is 10-25. The acrylic fibers have excellent crimp characteristics and anti-pilling properties.
