Abstract

Um cellulosische Fasern aus einer Lösung von Cellulose in einem tertiären Aminoxid und ggf. Wasser mit geringer Neigung zur Fibrillierung zur Verfügung zu stellen, werden die Fasern in mindestens zwei Stufen derart koaguliert, daß die Verweilzeit der Fasern in der ersten Fällungsstufe so eingestellt wird, daß bei Verlassen der ersten Fällungsstufe lediglich die Klebrigkeit der Oberfläche der zu Fasern geformten Lösung unterbunden ist und in weiteren Fällungsstufen die Fasern in einem spannungslosen Zustand gehalten werden und beim Verlassen der letzten Fällungsstufe die Fasern durchkoaguliert sind.
Die cellulosischen Fasern weisen eine neue Struktur auf und verfügen neben einer sehr geringen Neigung zur Fibrillierung über eine hohe Anfärbtiefe.
