  • Electrically-conductive fibres
    Patent number: 4388370
    Abstract: Finely divided, electrically-conductive particles are penetrated into an annular region located at the periphery of the sheath component of a drawn melt-spun sheath/core bicomponent fibre. The electrically conductive particles are present in an amount sufficient to render the fibre with an electrical resistance of less than 5.times.10.sup.9 ohms/cm. The fibre exhibits durable anti-static properties.
    Type: Grant
    Filed: August 26, 1975
    Date of Patent: June 14, 1983
    Assignee: Imperial Chemical Industries Limited
    Inventors: Vincent S. Ellis, Kazimierz W. Mieszkis
  • Production of modified conjugate fibre products
    Patent number: 4242382
    Abstract: A modified conjugate fibre product is formed by applying a predetermined amount of finely-divided particles to a conjugate fibre product and heating the product in an open, substantially tensionless condition at a non-sticking temperature (as defined) for 2 to 40 minutes. By this method, the particles penetrate into the fibre product without inter-fibre sticking taking place.
