Description

Verfahren zur Herstellung von Gebilden aus Acidylcellulosen Es -wurde gefunden, daB es beim Spinnen von Acidylcellulosen in Lösungs- oder Quellungsmitteln für die Acidylcellulosen enthaltende Salzlösungen zur Erzeugung guter Fäden von Vorteil ist, wenn man derartige Fällbäder mit einer Flüssigkeit überschichtet, welche die Acidylcellulosen nicht löst und sich zeit dem Fällbad nicht mischt. Zu diesem Zweck verwendet man zweckmäßig eine Schicht von Paraffinöl, Petroleum oder Olivenöl usw. Für Paraffinöl speziell hat sich. eine Schicht von über 3 cm Höhe als zweckmäßig erwiesen.Process for the production of structures from acidyl celluloses Es -wurde found that it occurs in the spinning of acidyl celluloses in solvents or swelling agents for the salt solutions containing acidyl celluloses to produce good threads of It is advantageous if such precipitation baths are covered with a liquid which the acidyl celluloses do not dissolve and do not mix during the precipitation bath. To this Purpose one uses appropriately a layer of paraffin oil, petroleum or olive oil etc. Has been specially developed for paraffin oil. a layer over 3 cm high is appropriate proven.
