Description

Verfahren zur Herstellung einer Spinnflüssigkeit, die eine durch Auflösen von Kaliumcellulosexanthogenat in Kalilauge gewonnene Viskose enthält. Bisher hat rnan zur Herstellung von Spinnlösungen aus Cellulose nach dem Viskoseverfahren fast ausschließlich Natronlauge verwendet, und zwar sowohl für die Merzerisierung der Cellulose als auch zum Lösen des nach der Schwefelkohlenstoffbehandlung entstandenen Natriumcellulosexanthogenats. Die Lösung der letztgenannten Verbindung hat den Namen Viskose bekommen. Natronlauge stellt einen billigen Grundstoff dar, billiger als die ebenfalls vorgeschlagene und auch in Zeiten mangelhafter Chemikalienzufuhr offenbar schon verwendete Kalilauge, welche ein mit Viskose analoges Produkt gibt und demselben Zweck dienen kann.Process for the preparation of a spinning liquid, which one by dissolving Contains viscose obtained from potassium cellulose xanthogenate in potassium hydroxide solution. So far has rnan for the production of spinning solutions from cellulose by the viscose process almost Only caustic soda is used, both for the mercerization of the Cellulose as well as for dissolving the resulting after the carbon disulfide treatment Sodium cellulose xanthate. The solution to the latter connection has the name Get viscose. Caustic soda is a cheap raw material, cheaper than the one that has also been proposed and is also evident in times of inadequate chemical intake Potash already used, which gives a product analogous to viscose, and the same Purpose can serve.

Auch ist es bekannt, Viskoselösungen Seife oder Fettsäuren zuzusetzen zum Zwecke einer besseren Spinnfähigkeit der Lösung und einer Verbesserun - der Eigenschaften des gesponnenen Produktes. Die Natriumviskose besitzt jedoch ,die Eigentümlichkeit, daß sie nur sehr wenig Natronseife oder Fettsäuren zu lösen vermag, und eine zugesetzte Seifenlösung, die nicht sehr verdünnt ist, wird bald niedergeschlagen, oder die Fettsäuren fallen nach ihrer Bindung schnell aus.It is also known to add soap or fatty acids to viscose solutions for the purpose of a better spinnability of the solution and an improver Features of the woven product. However, the sodium viscose possesses that Peculiarity that it can only dissolve very little soda soap or fatty acids, and an added soap solution, which is not very diluted, is soon knocked down, or the fatty acids precipitate quickly after they have been bound.

Es wurde nun gefunden, daß Kaliumviskose diesen Nachteil der Natriumviskose nicht oder jedenfalls in viel geringerem Maße besitzt. Es ist möglich, einer Kaliumcellulosexanthogenatlösung in verdünnter Kalilauge viel mehr Kaliseife oder Fettsäuren beizumischen, als es bei gewöhnlicher Natriumviskose der Fall ist, ohne daß die Gefahr des Wiederausfallens auftritt.It has now been found that potassium viscose this disadvantage of sodium viscose does not own it, or at least to a much lesser extent. It is possible to use a potassium cellulose xanthate solution Much more potash soap or fatty acids to be mixed in with dilute potassium hydroxide solution than there is is the case with ordinary sodium viscose, without the risk of reprecipitation occurs.

Der Zweck vorliegender Erfindung ist also die Herstellung einer Kaliumviskose, gemischt mit Kaliseife, und die Verwendung der erhaltenen Lösung zum Spinnen von künstlichen Textilprodukten, wie Kunstseide. oder zu anderen Zwecken.The purpose of the present invention is therefore the production of a potassium viscose, mixed with potassium soap, and the use of the resulting solution for spinning artificial textile products such as rayon. or for other purposes.

.Als Spinnbad kann jedes gebräuchliche Säurebad mit oder ohne Salzzufügung dienen, wobei man einen Teil oder- das ganze Salz durch Kaliumsulfat ersetzen kann.Any common acid bath with or without addition of salt can be used as a spinning bath serve, whereby you can replace part or all of the salt with potassium sulfate.

Beispiel I.Example I.

Einer Lösung von Kaliumxanthogenat in verdünnter Kalilauge werden a Prozent trokkene Kaliseife zugesetzt. Man mischt, bis die Seife gelöst ist, und verarbeitet die entstandene Mischung auf gewöhnliche Weise weiter. Beispiel z.A solution of potassium xanthate in dilute potassium hydroxide solution a percent dry potash soap added. Mix until the soap is dissolved and processes the resulting mixture in the usual way. Example

In Beispiel i wird die Kaliseife in Form einer konzentrierten Seifenlösung zugesetzt. Beispiel 3. In example i, the potassium soap is added in the form of a concentrated soap solution. Example 3.

Einer Lösung von Ka.liumxanthogenat in verdünnter Kalilauge wird I Prozent Fettsäure zugesetzt: Die Masse wird gerührt, bis Lösung eingetreten ist, und die entstandene Viskose auf gewöhnliche Weise weiterverarbeitet.A solution of potassium xanthate in dilute potassium hydroxide solution is I Percent fatty acid added: the mass is stirred until solution has occurred, and the resulting viscose is further processed in the usual way.
