Description
Verfahren zur Herstellung von beispielsweise mit Farbstoffen vom Typus der Metachromfarbstoffe walkecht färbbaren Kunstfasern aus regenerierter Cellulose Bei Verwendung von Kunstfasern jeglicher Art zur Beimischung zu Wolle, insbesondere bei Waren, für die besondere Tragechtheit gefordert wird, z. B. Lieferungstuche und Herrenstoffe, machen die färberischen Eigenschaften der Kunstfasern bisher große Sdhwie: rigkeiten, da das färberische Verhalten der üblichen Kunstfasern stark von dem der Wollfaser .abweicht. Besonders wenn Ansprüche an die Echtheitseigenschaften des Materials gestellt werden, war man bisher gezwungen, die beiden Faserarten durch getrennte Färbemethoden zu färben, oder man hatte bei gewissen anderen Färbemethoden den Nachteil, daß die Färbebäder nicht völlig erschöpft werden konnten, d. h. ein Verlust an Farbstoff auftrat.Process for the preparation of, for example, dyes of the type of the metachrome dyes, dyeable synthetic fibers made from regenerated cellulose When using synthetic fibers of any kind for admixture with wool, in particular for goods for which special wearing fastness is required, e.g. B. Delivery cloth and men's fabrics, make the dyeing properties of synthetic fibers so far great Sdhwie: rities, since the dyeing behavior of the usual synthetic fibers is strongly influenced by that of the wool fiber. Especially when there are demands on the authenticity properties of the material, one was previously forced to use the two types of fiber to dye separate dyeing methods, or one had to use certain other dyeing methods the disadvantage that the dyebaths could not be completely exhausted, d. H. a Loss of dye occurred.
Es sind zwar schon die verschiedensten Vorschläge gemacht worden, Kunstfasern mit N-haltigen Verbindungen, z. B. Eiweißverbindungen, die mit sauren Farbstoffen zu reagieren vermögen, zu behandeln oder sie den Fasern einzuverleiben. Es hat sich jedoch gezeigt, daß solche Fasern entweder nur schwach anfärbbar sind, vor allem schwächer als Wolle, mit :der sie zusammen gefärbtwur-,den, oder daß sie bei den üblichen Wollfärbernethoden während des Färbens bei höherer Temperatur oder insbesondere beim Walkprozeß den aufgenommenen Farbstoff wieder an die mitgefärbte Wolle abgeben. Dies letztere tritt besonders dann leicht auf, wenn die Fasern erst nachträglich mit Stickstoffverbindungen behandelt werden.A wide variety of proposals have already been made Synthetic fibers with N-containing compounds, e.g. B. Protein compounds with acidic Dyes are able to react, treat or incorporate them into the fibers. However, it has been shown that such fibers are either only weakly dyed, especially weaker than wool with: with which they were dyed together, or that they in the usual wool dyeing methods during dyeing at a higher temperature or especially during the fulling process, the absorbed dye is transferred back to the dye that was also dyed Give up wool. The latter occurs particularly easily when the fibers are first subsequently treated with nitrogen compounds.
Es wurde nun ein Verfahren gefunden, welches es ermöglicht, Mischgewebe aus Kunstfasern und Wolle im Einbädverfahren gleichmäßig und walkecht zu färben. Dieses Verfahren besteht darin, daß man einmal insbesondere Farbstoffe von der Art der sog. Metachromfarbstoffe zum Färben verwendet, d. h. Farbstoffe, die man in einem Bad unter Verwendung der Metachromheize (Ammoniumbichromat) gleichzeitig färben und chromieren kann. und andererseits bei der Herstellung der Kunstfaser diese in Gegenwart von Verbindungen, die mit den Farbstoffen der oben zuletzt genannten Art im @ neutralen Bade in Gegenwart der Chrombeize ohne Säurezusatz kochbeständige Verbindungen zu bilden vermögen, entstehen läßt. Solche Verbindungen sind die Kondensationsprodukte von Chlörhartparaffin und Polyäthylendiamin, die man der Spinnlösung zusetzen oder während der Spinnlösungs- oder Faserherstellung entstehen lassen kann.A method has now been found which makes it possible to produce mixed fabrics to dye from synthetic fibers and wool in the bathing process evenly and mill-fast. This method consists in the fact that once, in particular, dyes of the type the so-called metachrome dyes used for dyeing, d. H. Dyes that can be found in color in a bath using the metachrome heater (ammonium dichromate) at the same time and can chrome. and on the other hand in the production of the synthetic fiber this in Presence of compounds associated with the dyes of the last mentioned kind Boil-resistant in the neutral bath in the presence of the chrome stain without the addition of acid Able to form connections, lets arise. Such compounds are the condensation products of chlorinated paraffin and polyethylene diamine, which are added to the spinning solution or can arise during dope or fiber production.
Bei der Verwendung von Viscos@ekunstfaser wählt man vorteilhaft seine Viscosekunstseide, die in ihren Eigenschaften der Kupferkunstseide ähnlich ist. Es ist zweckmäßig, der Kunstfaser noch durch eine Behandlung mit wasserverdrängenden Mitteln gemäß dem Verfahren der österreichischen Patentschrift, 142879 wollähnliche Eigenschaften zu werleihen. In manchen Fällen empfiehlt es sich auch, die Faser vor dem Färben einer inigung unter Verwendung von Redukmitteln, wie Hydrosulfit, zu unterziehen. Beispiel i Einer Viscose niedrigen Reifegrades werden 3()/o ihres Gewichtes, bezogen auf den Cellulosegehalt, einer Base zugesetzt, die gemäß Patent 672 710 .durch Kondensation von Trichlorhartparaffin mit Polyäthylendiaminen erhalten wird. Sodann wird die Viscose versponnen, abgesäuert, gewaschen, zwecks Reinigung mit heißem Hydrosulfitbad behandelt, nochmals gewaschen und schließlich einer Nachbehandlung mit Alkohol unterworfen. Die Faser zeigt ein stark wollähnliches Aussehen.When using Viscos @ eynthetic fiber, it is advantageous to choose your viscose artificial silk, which is similar in its properties to copper artificial silk. It is advisable to give the synthetic fibers wool-like properties by treating them with water-displacing agents in accordance with the method of Austrian patent specification 142879. In some cases it is also advisable to subject the fiber to a reduction using reducing agents such as hydrosulphite before dyeing. Example I A low viscose ripeness are 3 () / o of its weight, based on the cellulose content of a base added to that obtained according to patent 672710 .by condensation of Trichlorhartparaffin with Polyäthylendiaminen. The viscose is then spun, acidified, washed, treated with a hot hydrosulfite bath for cleaning, washed again and finally subjected to an aftertreatment with alcohol. The fiber has a very wool-like appearance.
Ein Mischgewebe aus der so hergestellten Faser und Wolle läßt sich beispielsweise mit Metachrombrilläntblau 8 RL (S c h u 1 t z, Farbstofftabellen, 7. Auflage [1934], Ergänzungsband I, S. i i i) gleichmäßig und walk:echt färben. Beispiel 2 Einer Viscose des üblichen Reifegrades setzt man 2% einer Base, wie unter Beispiel i genannt, zu und verspinnt die Viscose in üblicher Weise. Das gewaschene Produkt wird bei 50° mit einer i %igen Wasserstoffsuperoxydlösung behandelt, wodurch, selbst wenn eine ziemlich gefärbte Base verwendet wurde, ein helles Fasermaterial erzielt -werden kann. Das fertige Fasermaterial färbt sich in Gegenwart von Wolle nach dem bekannten 1VIetachromfärbeverfahren, z. B. mit Metachromolivbraun G (S c h u 1 t z, Farbstofftabellen, 7. Aufl., Nr. 142) oder Metachrombraun 6 G (a. a. O., 1I. Band, S. i46), intensiv und volltändig walkecht an.A mixed fabric from the fiber and wool produced in this way can be used for example with metachrome brilliant blue 8 RL (S c h u 1 t z, dye tables, 7th edition [1934], supplementary volume I, pp. I i i) evenly and walk: real coloring. Example 2 2% of a base is added to a viscose of the usual degree of ripeness, as below Example i called and spun the viscose in the usual way. The washed The product is treated at 50 ° with a 1% hydrogen peroxide solution, whereby, even if a fairly colored base was used, a light fiber material can be achieved. The finished fiber material is colored in the presence of wool according to the known 1VIetachromfärbeverfahren, z. B. with metachromoliv brown G (p c h u 1 t z, color tables, 7th edition, no. 142) or Metachrome brown 6 G (op. O., 1I. Volume, p. I46), intense and completely whackfast.
Beispiel 3 Eine" Kupferammoniakcellulosespinnlösung, wie sie üblicherweise zum Erspinnen von Kupferkunstseide verwendet wird, wird in einem gut wirkenden Rührwerk mit 2()/o, bezogen auf den Cellulosegehalt der Lösung, einer Base, wie in Beispiel i genannt, versetzt, kurz entlüftet und im Spinntrichter nach bekannter Weise in Wasser versponnen, abgesäuert, geschnitten und wie üblich fertiggemacht.Example 3 A "copper ammonia cellulose dope as is commonly used used for spinning copper rayon is in a good working agitator with 2 () / o, based on the cellulose content of the solution, of a base, as in example i called, offset, briefly vented and in the spinning funnel in a known manner in Spun water, acidified, cut and finished as usual.
Erforderlichenfalls wird dem Nachbehandlungsgang eine Wasserstoftsuperotydbehandlung eingefügt.If necessary, a hydrogen superotide treatment is added to the aftertreatment course inserted.
Das auf diese Weise erhaltene Material läßt sich in gleicher Weise wie das der Beispiele i und 2 recht gut walkecht färben. So liefern beispielsweise Chromoxanreinblau B (Schultz, Farbstofftabellen, 7. Aufl. [193411, Ergänzungsband I, Teil 11, S. 59/6o), nach dem Metachromverfahren gefärbt, und Anthracenchromrot G (Schultz, Farbstofftabellen, 7.Aufl. [1931], Bd. i, S. 137), nachchromiert, praktisch gleich gut walkechte Färbungen wie die mitgefärbte Wolle.The material obtained in this way can be dyed quite well in the same way as that of Examples 1 and 2. For example, chromoxane pure blue B (Schultz, Farbstofftabellen, 7th edition [193411, supplementary volume I, part 11, p. 59/6o), colored according to the metachrome process, and anthracene chrome red G (Schultz, Farbstofftabellen, 7th edition [1931]) , Vol. I, p. 137), after-chromed, dyes that are practically as good as mill-fast dyeing as the wool dyed at the same time.
