Unter polymerem Acrylnitril hat man hier Polymere, Copolymere, gepfropfte Polymere oder deren Gemische zu verstehen, die 85 bis 100% Acrylnitril und bis zu 15% einer oder mehrerer polymerisierbarer äthylenischer Verbindungen enthalten.Under polymeric acrylonitrile one has here polymers, copolymers, grafted polymers or their Mixtures should be understood that contain 85 to 100% acrylonitrile and up to 15% of one or more polymerizable contain ethylenic compounds.

Es ist bekannt, das Verstrecken von synthetischen Fäden an der Luft durch einfachen Kontakt mit einer Heizvorrichtung oder in verschiedenen erhitzten Flüssigkeiten oder auch in Wasserdampf durchzuführen. Es ist ferner bekannt, das Verstrecken von unvollständig ausgebildeten Fäden aus Cellulosederivaten, während diese noch aus einem weichen Körper mit äußerer Kruste bestehen und noch nicht von ihrem Lösungsmittel befreit sind, nach Erweichen der äußeren Kruste durch Lösungsmitteldämpfe durchzuführen.It is known, the drawing of synthetic threads in the air by simple contact with a Carry out heating device or in various heated liquids or in steam. It is also known that the drawing of incompletely formed threads made of cellulose derivatives, while these still consist of a soft body with an outer crust and not yet are freed from their solvent after softening the outer crust by solvent vapors perform.

Erfindungsgegenstand ist ein Verfahren zum Verstrecken von Fäden aus polymerem Acrylnitril, die von ihrem Lösungsmittel befreit sind, dadurch gekennzeichnet, daß man die Fadenverstreckung in Dämpfen von Amylalkohol, Amylacetat oder Cyclohexanon durchführt.The subject of the invention is a process for drawing threads made of polymeric acrylonitrile, which are freed from their solvent, characterized in that the thread drawing in Steaming amyl alcohol, amyl acetate or cyclohexanone.

Einer der Hauptvorteile des erfindungsgemäßen Verfahrens besteht darin, daß das neue Verfahren eine Verstreckung mit einem höheren Grad ermöglicht, wobei der maximale Verstreckungsgrad, bei dem Fadenbruch auftreten würde, beträchtlich höher ist als bei den bis jetzt bekannten Verstreckungsverfahren. Außerdem ist für einen gleichen Verstreckungsgrad die Festigkeit nach erfindungsgemäßem Verstrecken höher als nach Verstrecken nach bekannten Verfahren. Das Verfahren eignet sich zum Verstrecken von Fäden, die durch Trockenspinnen erhalten worden sind, und ebensogut zum Verstrecken von Fäden, die durch Naßspinnen erhalten worden sind.One of the main advantages of the method according to the invention is that the new method allows stretching to a higher degree, the maximum degree of stretching at which Thread breakage would occur, is considerably higher than in the previously known drawing processes. In addition, for the same degree of stretching, the strength is after stretching according to the invention higher than after drawing by known methods. The process is suitable for drawing threads, obtained by dry spinning, and just as well for drawing threads passing through Wet spiders have been obtained.

Beispiel 1example 1

Ein Faden aus Polyacrylnitril wird zur Entfernung von restlichem Lösungsmittel mit Wasser gewaschen. Der maximale Verstreckungsgrad dieses Fadens in siedendem Wasser oder in Wasserdampf bei 1050C überschreitet 9 nicht. Wenn man ihn in einer warmen Zone, die Cyclohexanondämpfe bei 1530C enthält, verstreckt, so beträgt der maximale Verstreckungsgrad, für welchen Fadenbruch auftritt, 16,5.A thread made of polyacrylonitrile is washed with water to remove residual solvent. The maximum degree of drawing of this thread in boiling water or in steam at 105 ° C. does not exceed 9. If it is drawn in a warm zone which contains cyclohexanone vapors at 153 ° C., the maximum degree of drawing for which thread breakage occurs is 16.5.

Beispiel 2Example 2

Ein durch Verspinnen eines Gemisches von 85 Gewichtsprozent Polyacrylnitril und 15 Gewichtsprozent Polyvinylacetat erhaltener Faden wird von seinem Lösungsmittel befreit und dann in einer Zone, die Amylalkoholdämpfe bei 1310C enthält, verstreckt. Verfahren zum Verstrecken von Fäden aus

Der Faden kann auf einen Grad von 11,4 verstreckt werden, während der gleiche Faden in Wasserdampf nur auf einen Grad von 9 verstreckt werden kann.The thread can be drawn to a degree of 11.4 while the same thread is in steam can only be stretched to a degree of 9.

Beispiel 3Example 3

Ein Faden aus Polyacrylnitril, der von seinem Lösungsmittel befreit ist, wird auf das Siebenfache in Cyclohexanondämpfen bei 153° C verstreckt. Er besitzt dann eine um 20% höhere Trockenfestigkeit und eine um 18 % höhere Dehnung als der gleiche in Wasserdampf auf den gleichen Grad verstreckte Faden.A thread made of polyacrylonitrile, which has been freed from its solvent, is seven times as large stretched in cyclohexanone vapors at 153 ° C. He then has a 20% higher dry strength and an 18% higher elongation than the same in Steam on the thread drawn to the same degree.
