Description

Verfahren zum Färben von Kunstfasern und anderen Erzeugnissen aus Viscose. Die auf dem Wege des Kunstseideverfahrens gewonnenen Fasern, Fäden, Filme, Bänder o. dgl. aus Viskoselösung regenerierter Zellulose werden im Laufe ihrer Weiterverarbeitung zu textilen Erzeugnissen aller Art meist gefärbt.Process for dyeing synthetic fibers and other products Viscose. The fibers, threads, films, Ribbons or the like from cellulose regenerated from viscose solution are used in the course of their further processing mostly dyed for textile products of all kinds.

Das Färben der Fasern o. dgl. erfolgte bisher ausnahmslos nach der völligen Nachbehandlung der gesponnenen Fäden, d. h. nachdem sie gewaschen, entschwefelt, gebleicht und meist auch einmal getrocknet waren.The dyeing of the fibers or the like has so far always been carried out according to the complete post-treatment of the spun threads, d. H. after being washed, desulfurized, were bleached and usually dried once.

Es hat sich nun gezeigt, daß man das Färben mit besonderem Vorteil unmittelbar nach dem Waschen vornehmen kann, insbesondere bei Massenerzeugnissen, wie künstlichen Wollfasern, welche vor ihrer Verarbeitung in der Textilindustrie meist mit tierischen Fasern, wie Schafwolle oder Kunstwolle, gemengt werden. Es ergibt sich dabei der Vorteil, daß die Arbeitsvorgänge des Entschwefelns und Bleichens sowie ein Trockenvorgang in Fortfall kommen können, was zweifelsohne einen bedeutenden Fortschritt daxstellt.It has now been shown that dyeing is particularly advantageous can do immediately after washing, especially in the case of mass-produced items, such as artificial wool fibers, which before their processing in the textile industry usually mixed with animal fibers such as sheep's wool or synthetic wool. It there is the advantage that the desulfurization and bleaching operations and a drying process can be omitted, which is undoubtedly a significant one Shows progress.

Bei der Ausführung des Verfahrens setzt man der Farbflotte, mit welcher man die Viskoseprodukte, nachdem sie vom Fällbade befreit sind, behandelt, solche Stoffe zu, welche molekularen Schwefel lösen, wie z. B. Natriumsulfid, Natriumsulfit oder Natriumkarbonat. Mit besonderem Vorteil färbt man mit Schwefelfarbstoffen oder Küpenfarbstoffen in an sich bekannter Weise.When carrying out the process, one sets the dye liquor with which one treats the viscose products after they have been freed from the felling bath, such Substances that dissolve molecular sulfur, such as. B. sodium sulfide, sodium sulfite or sodium carbonate. It is particularly advantageous to dye with sulfur dyes or Vat dyes in a manner known per se.

Der Arbeitsvorgang ist hiernach gegeben. Als besonderer Vorteil ergibt sich auch eine große Aufnahmefähigkeit der Faser für die Farbstoffe, da die Faser im ersten gequollenen Zustand vorliegt, wie er beim späteren Wässern der einmal getrockneten Faser nicht mehr erreicht wird. Beispiel. q.oo kg gewaschene Viskosefaser mit einem Wassergehalt von etwa 75 Prozent wird in einem Färbeapparat mit umlaufender Flotte gefärbt mit 4000 l einer Flotte, welche beispielsweise enthält: 5 kg Immedialgrün GG, a kg Soda, zo kg Glaubersalz, 15 kg Schwefelnatrium 30 prozentig. Man färbt etwa eine Stunde bei 50° C; quetscht ab, wäscht mit kaltem Wasser und trocknet.The working process is given below. A particular advantage is that the fiber has a high capacity for absorbing the dyes, since the fiber is in the first swollen state, which is no longer achieved when the fiber, once dried, is later soaked. Example. q.oo kg of washed viscose fiber with a water content of about 75 percent is dyed in a dyeing machine with a circulating liquor with 4000 l of a liquor which contains, for example: 5 kg Immedialgrün GG, a kg soda, zo kg Glauber's salt, 15 kg sulfur sodium 30 percent. The dyeing is carried out for about an hour at 50 ° C .; squeezes, washes with cold water and dries.
