 beträchtliche   Losungsmittelverluste, was im vorliegenden   Verfahren vermieden wird. 



   Beispiel 1 : Der in der Spinnzelle gewonnene Faden aus Acetylcellulose wird im plastischen Zustand aus der Zelle abgeführt und läuft in den Streckraum, in welchen Wasserdampf geleitet wird. Zwischen dem zweiten Fadenführer und der Spule erfolgt die   Fadenstreekung.   Der Vorgang ist in der Zeichnung in Fig. 1 schematisch dargestellt. 



   Beispiel 2 : Das Spinnen erfolgt wie in Beispiel 1. Der noch plastische Faden gelangt in die   Tränkvorrichtung,   welche mit Benzol unter Zusatz einer   Ölschlichte   beschickt ist. Die Streckung erfolgt

 Fadenführer und Spule wird die Streckung hervorgerufen (Fig.   1     : 1 der Zeichnung).

 considerable loss of solvent, which is avoided in the present process.



   Example 1: The acetyl cellulose thread obtained in the spinning cell is discharged from the cell in its plastic state and runs into the stretching space, into which water vapor is conducted. The thread stretching takes place between the second thread guide and the bobbin. The process is shown schematically in the drawing in FIG.



   Example 2: The spinning takes place as in example 1. The still plastic thread reaches the impregnation device, which is charged with benzene with the addition of an oil size. The stretching takes place
 EMI1.4
 The thread guide and bobbin cause the stretching (Fig. 1: 1 of the drawing).

Claims (1)

PATENT-ANSPRUCH : Verfahren zur Herstellung feinfädiger Kunstseide nach dem Troekenspinnverfahren, dadurch gekennzeichnet, dass man den Faden, bevor er vollständig verfestigt ist, mit einem Quellungsmittel belädt und den an sich bekannten Streckmethoden unterwirft. **WARNUNG** Ende CLMS Feld Kannt Anfang DESC uberlappen**. PATENT CLAIM: Process for the production of fine-thread rayon by the dry spinning process, characterized in that the thread, before it is completely solidified, is loaded with a swelling agent and subjected to the stretching methods known per se. ** WARNING ** End of CLMS field may overlap beginning of DESC **.
