Abstract

Kompositfasern werden hergestellt durch

  • (a) Vermischen einer PTFE- oder PTFE-Copolymer-Dispersion oder eines PTFE- oder PTFE-Copolymer-Pulvers mit einem feinteiligen anorganischen Material und einem faserbildenden Material,
  • (b) Erhitzen des erhaltenen Gemisches unter Scherung auf eine Temperatur, bei der das PTFE oder PTFE-Copolymer unter Scherung fließfähig ist, aber keine Zersetzung zeigt, unter Entfernung des Dispergiermittels, sofern eine PTFE- oder PTFE-Copolymer-Dispersion eingesetzt wird,
  • (c) Abkühlen des Gemisches auf eine Temperatur unterhalb von 70°C,
  • (d) Scheren des Gemisches unter Mischen bei einer Temperatur unterhalb von 70°C zur Bildung der Kompositfasern.
    • Composite fibers are made by
  • (a) mixing a PTFE or PTFE copolymer dispersion or a PTFE or PTFE copolymer powder with a finely divided inorganic material and a fiber-forming material,
  • (b) heating the mixture obtained under shear to a temperature at which the PTFE or PTFE copolymer is flowable under shear but shows no decomposition, with removal of the dispersant, if a PTFE or PTFE copolymer dispersion is used,
  • (c) cooling the mixture to a temperature below 70 ° C,
  • (d) shearing the mixture with mixing at a temperature below 70 ° C to form the composite fibers.

    • Die Kompositfasern können zur Herstellung von Diaphragmen eingesetzt werden.The composite fibers can be used to manufacture diaphragms.
