Description
Bekanntlich gehen die Lösungen von Cellulosexanthogenaten (Viskose) nach Erlangung des für die Fadenbildung besonders geeigneten, sogenannten Reifezustandes, sehr bald unter weiterer Umsetzung in einen für den Zweck weniger geeigneten, sogenannten überreifen Zustand über.As is well known, the solutions come from cellulose xanthogenates (Viscose) very soon after it has reached the so-called state of maturity that is particularly suitable for thread formation further implementation in a so-called overripe state that is less suitable for the purpose above.
Es hat sich nun gezeigt, daß man durch Zusatz von Stoffen, die Amid- oder ImidgruppenIt has now been shown that by adding substances, the amide or imide groups
ίο enthalten, oder sich in der Viskoselösung unter Bildung solcher Gruppen umsetzen können, nicht allein die Haltbarkeit der Viskose verbessern, sondern daß man auch durch diese Beimischungen einen erheblichen technischen Erfolg durch Verbesserung der aus Viskose herzustellenden Gebilde, wie Fäden, Films u. dgl. erzielen kann, namentlich wenn man den Fällungsbädern Formaldehyd zusetzt. 1 Als besonders geeignet für diese Zusätze sind bisher folgende Verbindungen erprobt worden: Harnstoff, Harnstoffderivate, Cyanamid, Dicyandiamid, Guanidin und Guanidinderivate, Säureamide wie Acetamid usw., die Urethane und Cyanate, sowie die entsprechenden schwefelhaltigen Verbindungen, wie Thioharnstoffe, Senföle und Rhodanverbindungen. Diese Verbindungen können als solche oder soweit sie dazu befähigt sind, mit durch Kondensation mit Aldosen maskierter Amidgruppe der Viskoselösung zugemischt werden.ίο included, or in the viscose solution Can implement the formation of such groups, not only improve the shelf life of the viscose, but that one can also achieve considerable technical success through these admixtures by improving the viscosity of viscose structures to be produced, such as threads, films and the like, can be achieved, especially if one uses the precipitation baths Formaldehyde adds. 1 The following compounds have so far been tested as being particularly suitable for these additives been: urea, urea derivatives, cyanamide, dicyandiamide, guanidine and guanidine derivatives, Acid amides such as acetamide, etc., the urethanes and cyanates, as well as the corresponding sulfur-containing compounds such as thioureas, mustard oils and rhodan compounds. These compounds can be used as such or to the extent that they are capable of doing so, by means of condensation Amide groups masked with aldoses are added to the viscose solution.
Man verfährt in der Weise, daß man der wie üblich hergestellten Viskose nach völliger Auflösung unter gutem Rühren die vorteilhaft vorher in Wasser gelösten Stoffe:,zumischt.....The process is performed in such a manner that the viscose prepared as usual for complete dissolution with thorough stirring, the advantageous previously dissolved in water materials: admixed .....
Die Haltbarkeit der Viskoselösungen wird dadurch soweit vermehrt, daß man noch nach Wochen gute Fadenbildung damit erzielen kann und daß die Fäden sich durch große Stärke auszeichnen, gegen Wasser aber, namentlich bei der Benutzung eines Formaldehyd enthaltenden Fällungsbades, besonders empfindlich sind.The shelf life of the viscose solutions is increased to such an extent that one is still after Weeks can achieve good thread formation and that the threads through large Strength distinguishes itself, however, against water, especially when using a formaldehyde-containing one Precipitation bath, are particularly sensitive.
Zu einer in bekannter Weise hergestellten Viskoselösung wird nach erreichtem Reifezustand oder auch früher eine kleine Menge der benannten Zusätze, am besten vorher in Wasser gelöst, eingerührt. Bei Harnstoff z. B. genügen etwa 2 Prozent von dem Gewicht der Zellulose; Cyanamid wird vorteilhaft in Verbindung mit Aldosen angewandt.A viscose solution prepared in a known manner becomes after reaching the state of maturity or earlier a small amount of the named additives, preferably dissolved in water beforehand, stirred in. For urea z. B. about 2 percent of the weight of the cellulose is sufficient; Cyanamide is beneficial in conjunction applied with aldoses.
Zu dem Zwecke werden z. B. 50 g Kalkstickstoff mit einer Zucker- oder Melasselösung, welche 100 g Zucker in 250 g Wasser enthält, verrührt. Nach beendeter Einwirkung (der Zucker bildet mit dem Cyanamid eine Verbindung) wird die klare Lösung vom Unlöslichen getrennt und mitgelöster Kalk durch Kohlensäure gefällt. Dieses Präparat wird dann der Viskoselösung zugegeben und zwar in Mengen, so daß etwa 4'Prozent Zucker auf die gelöste Zellulose verwendet wird.For this purpose z. B. 50 g calcium cyanamide with a sugar or molasses solution, which contains 100 g sugar in 250 g water, stirred. After the end of the exposure (the Sugar forms a compound with the cyanamide) becomes the clear solution of the insoluble separated and dissolved lime precipitated by carbonic acid. This preparation is then added to the viscose solution in amounts such that about 4 percent sugar is used on the dissolved cellulose.
