Description

Verfahren zur Behandlung von Kunstseide und anderen künstlichen Textilprodukten aus Viskose. ES kommt öfters vor, daß Kunstseide und andere künstliche Textilfäden, welche aus Viskose gesponnen sind, mangelhaften Glanz zeigen, insbesondere treten z. B. häufig Flecken auf, deren Ursache nicht immer klar ist und die Qualität des gesponnenen Produktes im hohen Maße herabsetzen. Um diese Flecken zu beseitigen, gibt es bis jetzt kein Mittel, das immer guten Erfolg hat.Process for treating rayon and other artificial textile products made of viscose. It often happens that rayon and other artificial textile threads, which are spun from viscose, show poor gloss, especially step z. B. often spots, the cause of which is not always clear and the quality of the to a great extent minimize woven product. To remove these stains, up to now there is no remedy that always has good results.

Durch vorliegende Erfindung gelingt es nun, fleckenfreie Kunstfäden zu spinnen, und zwar dadurch, daß man die Fäden einer Dehandlung mit Fluorwasserstoffsäurelösung unterzieht. Man kann die Behandlung z. B. nach der Koagulierung der Viskose in einem zweiten Nachbehandlungsbad stattfinden lassen, wo die auf Spulen gewickelten Fäden rundlaufen, ioder man kann auch schon zum Spinnbade die Flußsäure zugeben. Schließlich kann man auch die ganz fertigen Strähnen mit einer verdünnten Flußsäurelösung behandeln, nachher waschen und wieder trocknen. Die zur Behandlung verwendete Lösung muß natürlich ziemlich verdünnt sein, einige Prozent genügen schon, um den gesuchten Effekt hervorzurufen.The present invention now makes it possible to produce stain-free synthetic threads to spin the threads by treating them with hydrofluoric acid solution undergoes. You can treat z. B. after coagulation of the viscose in one Let the second aftertreatment bath take place where the threads wound on bobbins run around, or you can add the hydrofluoric acid to the spinning bath. In the end you can also treat the completely finished strands with a dilute hydrofluoric acid solution, afterwards wash and dry again. The solution used for treatment must of course be fairly diluted, a few percent are enough to produce the desired effect.

Beispiel i.Example i.

Die ganz fertigen Strähnen, welche mangelhaften Glanz oder Flecke zeigen, werden während kurzer Zeit, z. B. 5 Minuten, in einer Flußsäurelösung untergetaucht,; danach schnellstens ausgewaschen und getrocknet. Beispiel a.The completely finished strands, which lack gloss or stains show, for a short time, e.g. B. 5 minutes, submerged in a hydrofluoric acid solution; then washed out and dried as quickly as possible. Example a.

Die Viskose wird in einem Spinnbade gesponnen, das neben den gewöhnlichen Bestandteilen, wie Mineralsäure und Salze, 2 bis 5 Prozent H F1 enthält.The viscose is spun in a spinning bath, which is next to the ordinary Ingredients, such as mineral acids and salts, contain 2 to 5 percent H F1.

Beispiel 3. Example 3.

Die schon vorkoagulierten Fäden werden in einem zweiten Nachkoagulierungsbade,, in welchem die Spule oder Haspel rundläuft und das z bis 5 Prozent H F1 enthält, nachbehandelt.The already pre-coagulated threads are put in a second post-coagulation bath. in which the bobbin or reel runs smoothly and contains up to 5 percent H F1, post-treated.
