Es ist bereits bekannt, geformte Gebilde aus regenerierter Cellulose, wie Fäden oder Filme, zu erzeugen, indem man der Viskose in einem beliebigen Stadium der Xanthogenierung und bzw. oder dem sauren Fällbade Verbindungen von verschiedenartiger chemischer Struktur zusetzt. Hiermit wird im allgemeinen eine erhöhte Entquellung der Fäden im sauren Spinnbad bewirkt. Die bekannten Zusatzmittel besitzen jedoch den Nachteil, daß zur Erlangung der gewünschten Gebildeeigenschaften die Elektrolytkonzentration im sauren Spinnbad in engen und niedrigen Bereichen gehalten werden muß. Da die Einhaltung dieser Konzentrationsbereiche mühevoll ist, treten bei den bekannten Modifizierungsmittel leicht Spinnschwierigkeiten auf, insbesondere bei der Verstreckung der Spinngebilde. So sind z.B. bereits ω-Aminoalkyläther von Oxäthylaten von aliphatischen Carbonsäureamiden, Fettsäureamide von N-Hydroxyäthyl-äthylendiamin, Oxäthylate von Fettsäure-oxyalkylamiden sowie Oxäthylate von Polyaminen, die mit Spermölfettsäure partiell amidiert sind, als Viskosemodifizierungsmittel beschrieben (vgl. zum Beispiel die deutschen Auslegeschriften 1 071 278 und 1 035 849, USA.-Patentschrift 2 432 127, belgische Patentschrift 597656). Die Löslichkeit der genannten Verbindungen in der Viskose ist jedoch unbefriedigend.It is already known to produce shaped structures from regenerated cellulose, such as threads or films, by the viscose in any stage of the xanthation and / or the acidic precipitation bath Adds compounds of different chemical structure. This is generally a causes increased swelling of the threads in the acidic spinning bath. However, the known additives have the disadvantage that the electrolyte concentration in the acidic spin bath must be kept in narrow and low areas. Because compliance with these concentration ranges is troublesome, spinning difficulties easily occur with the known modifiers on, especially when stretching the spun structure. For example, ω-aminoalkyl ethers are already there of oxethylates of aliphatic carboxamides, fatty acid amides of N-hydroxyethyl-ethylenediamine, Oxethylates of fatty acid oxyalkylamides and oxethylates of polyamines with sperm oil fatty acid are partially amidated, described as viscose modifiers (see, for example, the German Auslegeschriften 1,071,278 and 1,035,849, U.S. Patent 2,432,127, Belgian Patent 597656). However, the solubility of the compounds mentioned in the viscose is unsatisfactory.

worin R einen Alkylrest mit 5 bis 13 Kohlenstoffatomen, X eine Oxalkylgruppe mit 2 bis 4 Kohlenstoffatomen und η eine Zahl von etwa 5 bis 30 bedeutet, bei der Herstellung von geformten Gebilden, insbesondere Fäden oder Filmen, aus regenerierter Cellulose durch Auspressen von Viskose in an sich bekannte Fällbäder als Modifizierungsmittel unter Zusatz zur Viskose und bzw. oder zum sauren Fällbad.where R is an alkyl radical with 5 to 13 carbon atoms, X is an oxalkyl group with 2 to 4 carbon atoms and η is a number from about 5 to 30, in the production of shaped structures, in particular threads or films, from regenerated cellulose by pressing out viscose in an known precipitation baths as modifiers with addition to viscose and / or to the acidic precipitation bath.

Oxäthylgruppe darstellt, der mittlere Oxalkylierungsgrad η zwischen 10 und 20 liegt und der Alkylrest R 8 bis 11 KohlenstofTatome besitzt.Represents oxethyl group, the average degree of oxyalkylation η is between 10 and 20 and the alkyl radical R has 8 to 11 carbon atoms.
Die unter Zusatz der erfindungsgemäß verwendeten Modifizierungsmittel erhaltenen Gebilde zeigen verbesserte Eigenschaften hinsichtlich Festigkeit und Dehnung. Insbesondere zeigen die Fäden und Fasern eine stärkere Mantelzone, und ihr Querschnitt weist eine Vollmantelstruktur auf. Derartige Fäden zeigen auch eine erniedrigte Quellneigung. Somit bedeutet das Verfahren einen wesentlichen technischen Fortschritt für die Erzeugung von hochfesten Viskosefasern, z. B. für die Herstellung von hochfesten Stapelfasern. Ferner wird die Bildung von Absetzungen in der Spinnapparatur verhindert, z. B. das Zuwachsen von Spinndüsenlöchern bei Gegenwart von Zinksalzen.The structures obtained with the addition of the modifying agents used according to the invention show improved results Properties in terms of strength and elongation. In particular, the threads and fibers show one stronger jacket zone, and its cross-section has a full jacket structure. Such threads also show a decreased tendency to swell. Thus, the process means a significant technical advance for the production of high-strength viscose fibers, e.g. B. for the production of high-strength staple fibers. Further the formation of deposits in the spinning equipment is prevented, e.g. B. the growth of spinneret holes in the presence of zinc salts.
Außerdem zeigen die gemäß der Erfindung verwendeten Modifizierungsmittel infolge ihrer völlig andersartigen Substitution die Mängel der bekannten Mittel nicht, wodurch der Anwendungsbereich hinsichtlich der Konzentration der Spinnbäder an Säuren und Salzen, insbesondere auch hinsichtlich der Zinksalze, bei gleichmäßiger Erhaltung der gewünschten Gebildeeigenschaften erheblich erweitert wird.In addition, the modifying agents used according to the invention show, as a result of their completely different nature Substitution of the shortcomings of the known means does not, whereby the scope with regard to the concentration of acids and salts in the spinning baths, especially with regard to zinc salts, is expanded considerably while maintaining the desired structural properties.
Ein bedeutender Vorteil der erfindungsgemäß zu verwendenden Modifizierungsmittel besteht weiterhin darin, daß sie im Unterschied zu den bekannten aliphatischen Aminen oder ihren Derivaten physiologisch indifferent sind.There is still a significant advantage of the modifying agents to be used according to the invention in that, in contrast to the known aliphatic amines or their derivatives, they are physiological are indifferent.
Hervorzuheben ist ferner, daß die erfindungsgemäß zu verwendenden Modifizierungsmittel mit den meisten bekannten Modifizierungsmitteln verträglich sind. Man kann also bequem durch Zusatz der bekannten Modi-It should also be emphasized that the modifiers to be used according to the invention with most known modifiers are compatible. So you can easily add the well-known modes
