Description

Verfahren und Vorrichtung zur Herstellung künstlicher Hohlfäden Zur Herstellung von hohlen, künstlichen Fäden sind eine Anzahl von Verfahren vorgeschlagen worden, bei denen der Spinnmasse Luft oder andere indifferente Gase eingeblasen werden, welche durch Rühren innerhalb der Spinnmasse fein verteilt werden.Method and device for the production of artificial hollow fibers Zur A number of methods have been suggested for making hollow, man-made sutures where air or other inert gases are blown into the spinning mass which are finely distributed by stirring within the spinning mass.

Um die vielen kleinen Bläschen zu lösen, setzt man das Gemisch unter Druck. Beim Austritt der unter Druck stehenden Masse aus der Spinndüse dehnen sich die gelösten Gasblasen aus, die in den im gleichen Augenblick sich bildenden festen Fäden eingeschlossen werden. In order to loosen the many small bubbles, the mixture is added Pressure. When the pressurized mass emerges from the spinneret, they expand the dissolved gas bubbles from the solid ones that are formed in the same instant Threads are included.

Andere Verfahren, i.B. das Viskoseverfahren, verwenden gasentwickelnde Substanzen, beispielsweise Natriumcarbonat, das der Viskose zugesetzt wird, und das beim Austritt der viskosen Flüssigkeit aus der Düse in das Fällbad Kohlensäure entwickelt, welche ebenfalls in den entstehenden Faden eingeschlossen wird. Other methods, i.B. the viscose process, use gas-evolving Substances, for example sodium carbonate, which is added to the viscose, and carbonic acid when the viscous liquid emerges from the nozzle into the precipitation bath developed, which is also included in the resulting thread.

Diese Verfahren ermöglichen aber keine reichliche und gleichmäßige Verteilung der Gasblasen in der Spinnflüssigkeit und im Faden. However, these methods do not allow abundant and uniform Distribution of the gas bubbles in the spinning liquid and in the thread.

Es hat sich nun gezeigt, daß sich die gewünscht feine Verteilung der Gasblasen im Faden dadurch erreichen läßt, wenn man das Einleiten der Gase mit einer Vorrichtung vornimmt, die sich in der Masse bewegt. Es wird dadurch erreicht, daß eine große Menge feiner Gasblasen fortwährend mit neuen Teilen der masse in Berührung kommt, was die gewünschte Gleichmäßiglceit und Feinheit der Verteilung herbeiführt. Wenn die Masse während dieser Operation gleichzeitig unter Druck gehalten wird, so findet ein fortgesetztes Lösen der sich bildenden Gasblasen statt, und die Aufnahmefähigkeit und Verteilung für die Blasen wird besonders begünstigt. It has now been shown that the desired fine distribution is achieved the gas bubbles in the thread can be achieved by introducing the gases with a device that moves in the mass. It is achieved by that a great number of fine gas-bubbles are continually filled with new parts of the mass Touch comes what the desired uniformity and delicacy of distribution brings about. When the mass is kept under pressure at the same time during this operation the gas bubbles that are formed continue to dissolve, and the absorption capacity and distribution for the bubbles is particularly favored.

Man kann beispielsweise wie folgt verfahren: Ein Kessel, der mit Viskose beschickt ist, hat ein Rührwerk, dessen Achse hohl ist und an welcher sich eine große Anzahl von übereinander angeordneten hohlen Armen, z. B. Rohre, befinden, die mit vielen kleinen Löchern versehen sind. Das Rührwerk wird in langsame Bewegung gesetzt, und gleichzeitig wird durch die hohle Achse Luft oder ein anderes indifferentes Gas eingeblasen, welches durch die vielen kleinen Oeffnungen fortlaufend an neuen Stellen der Viskose in dieselbe eintritt. Man kann aber auch an Stelle des Einleitens der Luft während der Bewegung beide Operationen getrennt und abwechselnd nacheinander ausführen. Der Kessel bleibt geschlossen, so daß nach kurzer Zeit ein Überdruck entsteht, durch welchen die eingetretenen Gasbläschen komprimiert werden, so daß nach einiger Zeit eine stark mit Gas durchsetzte Lösung erhalten wird, die sofort in üblicher Weise versponnen werden kann. You can proceed as follows, for example: A boiler that is connected to Viscose is charged, has an agitator, the axis of which is hollow and on which a large number of superposed hollow arms, e.g. B. pipes, are located, which are provided with many small holes. The agitator will move slowly set, and at the same time air or some other indifferent thing is introduced through the hollow axis Gas is blown in, which is continuously fed through the many small openings Make the viscose enter the same. But you can also instead of introducing it the air during movement both operations separately and alternately one after the other carry out. The boiler remains closed, so that overpressure occurs after a short time arises, through which the entered gas bubbles are compressed, so that after some time a strongly gas-permeated solution is obtained which immediately can be spun in the usual way.

Es sind bereits Rühr- und Mischwerke bekannt, bei denen das Mischgut mittels Rührer und Luftstrahlen durchgearbeitet wird. Agitators and mixers are already known in which the material to be mixed is worked through using a stirrer and air jets.

Diese Vorrichtungen bestehen ihrem Verwendungsiweck entsprechend aus offenen Gefäßen, so daß der Gefäß inhalt nicht unter Druck gesetzt werden kann, denn es ist hier weder beabsichtigt noch erforderlich, daß die zum Mischen verwendete Luft im Mischgut erhalten bleibt Dies ist aber eine Bedingung, die für die Erzeugung von hohlen, künstlichen Fäden aus Celluloseverbindungen durch Einleiten von Luft in die Spinnmasse unerläßlich ist.These devices exist for their intended purpose corresponding from open vessels so that the contents of the vessel cannot be pressurized, because it is neither intended nor required here that the one used for mixing Air is retained in the mix. However, this is a condition for the production of hollow, artificial threads made of cellulose compounds by introducing air is indispensable in the spinning mass.

In der Abbildung ist eine beispielsweise Ausführungsform einer für das Verfahren nach der Erfindung verwendbaren Vorrichtung schematisch dargestellt. In the figure, an example embodiment is one for the method according to the invention usable device shown schematically.

Ein Kessel 1 zur Aufnahme der Spinnmasse, der nach Art der bekannten Druckkessel ausgebildet ist, hat ein Rührwerk mit einer hohlen Achse 2, die eine größere Anzahl von röhrenförmigen Annen 3 trägt. Die Hohlräume dieser Arme stehen mit dem Hohlraum der Achse in Verbindung; die Arme selbst sind mit vielen feinen Löchern versehen, die als Gasaustrittslöcher dienen. Auf dem Deckel des Kessels befinden sich die Eintrittsöffnungen 4 für die Spinnmasse und ein Entlüftungsstutzen 5. Am Boden des I Kessels befindet sich die Austrittsöffnung 6 für die fertige Spinnmasse, die von dort zur Spinnmaschine geleitet wird. A boiler 1 for receiving the spinning mass, which is in the manner of the known Pressure vessel is formed, has an agitator with a hollow axis 2, the one larger number of tubular annen 3 carries. The cavities of these arms stand in communication with the cavity of the axle; the arms themselves are fine with many Provided holes that serve as gas outlet holes. On the lid of the kettle are the inlet openings 4 for the spinning mass and a vent 5. The outlet opening 6 for the finished spinning mass is located at the bottom of the I boiler, from there to the spinning machine.
