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.To make cellulosic fibers from a solution of cellulose in one tertiary amine oxide and possibly water with a low tendency to fibrillation To provide the fibers in at least coagulated two stages so that the residence time of the Fibers in the first precipitation stage is adjusted so that at Leaving the first precipitation stage, only the stickiness the surface of the solution formed into fibers is prevented and in further precipitation stages the fibers in a tension-free Condition and when leaving the last precipitation level the fibers are coagulated.

Die cellulosischen Fasern weisen eine neue Struktur auf und verfügen neben einer sehr geringen Neigung zur Fibrillierung über eine hohe Anfärbtiefe.The cellulosic fibers have a new structure and have a very low tendency to fibrillation over a high staining depth.
