Abstract

Verfahren zur Herstellung von poromerem Kunstleder, wobei man

  • I. ein im wesentlichen porenfreies Imprägnat herstellt, indem man ein textiles Flächengebilde mit einer wässerigen Polyurethandispersion imprägniert, trocknet und
  • II. aus dem Imprägnat ein poromeres Kunstleder herstellt, indem man auf das Imprägnat eine wässerige Lösung einer Brönsted-Base einwirken läßt.
    • Process for the production of poromeric synthetic leather, whereby one
  • I. produces an essentially pore-free impregnate by impregnating, drying and drying a textile fabric with an aqueous polyurethane dispersion
  • II. Manufacture a poromeric synthetic leather from the impregnate by allowing an aqueous solution of a Bronsted base to act on the impregnate.
