Abstract

Die Erfindung betrifft ein Verfahren zum Herstellen eines Vlieses insbesondere zur Verwendung für Unterspannbahnen für Bedachungen, bestehend aus einem thermoplastischen Kunststoff, bei welchem Verfahren

  • eine Schmelze aus dem Kunststoff hergestellt,
  • die Schmelze mittels eines Extruders kontinuierlich zu Fasern versponnen
  • und aus den Fasern ein Vlies gebildet und insbesondere punktförmig gebondet wird z. B., indem
  • das Vlies durch einen entsprechenden Kalander geführt wird.
The invention relates to a method for producing a nonwoven, in particular for use for underlays for roofs, consisting of a thermoplastic, in which method
  • a melt made from the plastic,
  • the melt is continuously spun into fibers using an extruder
  • and a fleece is formed from the fibers and in particular is point-bonded z. B. by
  • the fleece is passed through an appropriate calender.

Um ein solches Verfahren der vorstehenden Art zu schaffen, mit dem sich ein Vlies herstellen läßt, das sich durch eine hohe Wasserdichtigkeit und gleichzeitig durch eine relativ hohe Wasserdampfdurchlässigkeit auszeichnet, wird erfindungsgemäß vorgesehen, daß für das Vlies ein Hydrophobierungsmittel verwendet wird, das insbesondere der Schmelze des Kunststoffs zugesetzt werden kann.In order to create such a method of the above kind, with which a fleece can be produced, which can be replaced by a high water resistance and at the same time through a relative Characterized by high water vapor permeability, is according to the invention provided that a hydrophobizing agent for the fleece is used, in particular the melt of the plastic can be added.
