Description

Verfahren zur Herstellung von Kautschukfäden Die Erfindung betrifft die Herstellung von Fäden aus Kautschukmilch.Method of making rubber thread The invention relates to the manufacture of threads from rubber milk.

Das Wesen der Erfindung besteht darin, daß die Kautschukmilch, in die ein Koagulationsmittel eingespritzt wird, zerkleinerte Faserstoffe enthält. Ein weiteres Merkmal der Erfindung besteht darin, daß zusammen mit dem Koagulationsmittel in die Kautschukmilch ein fester Kern eingeführt werden kann, auf dem die Kautschukmilch durch das Koagulationsmittel niedergeschlagen wird.The essence of the invention is that the rubber milk, in which is injected with a coagulant contains shredded fiber. Another feature of the invention is that together with the coagulant a solid core can be introduced into the rubber milk, on which the rubber milk is precipitated by the coagulant.

Bei der Ausführung des Verfahrens wird beispielsweise ein sehr dünner Strahl eines Koagulierungsmittels, das aus etwa 5- bis 25%iger Essigsäure bestehen kann, in Kautschukmilch geleitet, die zerkleinerte Faserstoffe, wie Baumvolle, künstliche Seide oder Wolle, enthält.When performing the method, for example, a very thin one becomes A jet of coagulant consisting of about 5-25% acetic acid can, passed into rubber milk, contain the crushed fibers, such as tree-filled, artificial ones Contains silk or wool.

Sobald der Strom des Koagulierungsmittels in, die Kautschukmilchmischurng eintritt, erfolg t durch örtliche Koagulation um diesen herum die Bildung des Kautschukfadens. Dieser Faden wird eine Strecke weit durch die Kautschukmilch weiter hindurchgeführt, um weitere Kautschukmengen auf dem so gebildeten Kern niederzuschlagen, der noch einen koagulierenden Einfluß ausübt. Danach wird der Faden aus dem Bad herausgehoben und erhält, gerade bevor er den Spiegel des Kautschtikmilchbades vcrläßt, einen letzten und sehr glatten Überzug aus Kautschukmilch. Der Faden kann dann zur weiteren Behandlung in üblicher Weise weitergeführt werden.As soon as the flow of coagulant in, the rubber milk mixture occurs, local coagulation around this leads to the formation of the rubber thread. This thread is passed a distance through the rubber milk, to deposit further amounts of rubber on the core formed in this way, which is still exerts a coagulating influence. Then the thread is lifted out of the bath and receives one just before he leaves the bubble bath last and very smooth coating of rubber milk. The thread can then be used for further Treatment can be continued in the usual way.

Die Kautschukmilch kann auch mit den gebräuchlichen Zusätzen gemischt werden, je nach den Eigenschaften, die das Garn haben soll.The rubber milk can also be mixed with the usual additives depending on the properties that the yarn should have.

Der geformte Faden, der das Kautschukmilchbad verläßt, kann anschließend durch ein Koagulierungsbad geschickt werden, wodurch vor dem Trocknen eine völlige Koagulierung gesichert wird.The shaped thread that leaves the rubber milk bath can then be sent through a coagulation bath, which makes a complete before drying Coagulation is secured.

Mit dem Koagulierungsstrom kann ein aus gesponnenem Glas, Papier o. dgl. bestehender Fadenkern durch das Kautschukmilchbad laufen, um so einen zeitweilig sich nicht verlängernden Kautschukfaden zu erhalten.A spun glass, paper or similar can be used with the coagulation stream. Like. Existing thread core run through the rubber milk bath so as to temporarily to obtain non-elongating rubber thread.

Der Fadendurchmesser kann durch die Dicke des koagulierenden Strahles, dessen Geschwindigkeit oder die Stärke des Koagulierungsmittels, die im Falle von Essigsäure bis ioo o;'o, aber auch nur wenige Prozente betragen kann, durch den Trockengehalt des Kautschukmilchbades und durch die Weglänge des koagulierenden Fadens im Kautschul,-milchbad selbst bestimmt werden.The thread diameter can be determined by the thickness of the coagulating jet, its speed or the strength of the coagulant, which in the case of Acetic acid up to ioo o; 'o, but can also be only a few percent through which Dry content of the rubber milk bath and by the path length of the coagulating Thread in the chewing school or milk bath can be determined by oneself.

Nach dein oben beschriebenen Verfahren erhält man einen Faden, der in ein Gewebe ohne weitere, die Reibung vermindernde Schutzumhüllung verwebt werden kann.Following the procedure described above, you get a thread that are woven into a fabric without any additional protective covering to reduce friction can.
