Description

Verfahren zum Buntreservieren von Anilinschwarz und ähnlichen Oxydationsfarbstoffen mit Küpenfarbstoffen. Anilinschwarz kann man- bekanntlich in der Weise mit Küpenfarbstoffen buntreservieren, daß man einer stark alkalischen Druckfarbe Sitrlfoxylate und die Küpenfarbstoffe zugibt, aufdruckt, dämpft und durch Waschen, allenfalls mit einer Passage in Lösungen von Bichromaten, den reduzierten Küpenfarbstoff entwickelt und fixiert.Process for the color reservation of aniline black and similar oxidizing dyes with vat dyes. As is well known, aniline black can be produced in the same way with vat dyes Reserve color that you can use a strongly alkaline printing ink Sitrlfoxylate and the Adds vat dyes, prints, steams and washing, if necessary with one Passage in solutions of bichromates, the reduced vat dye developed and fixed.

Bei diesem bekannten Verfahren geht also die Reservierung des Schwarz sowie die Reduktion des Küpenfarbstoffes in einem einzigen Arbeitsgang, dein Dämpfen, vor sich. Die Verwendung von starken Alkalien bei diesem Verfahren hat den Übelstand, daß sich nicht nur im Dampf unangenehm wirkende weiße Höfe um die Buntätzeffekte herum bilden, Sonden es werden auch außerdem die angewandten Küpenfarbstoffe keineswegs restlos auf der Faser fixiert, so daß blasse, unansehnliche Bunteffekte erzielt werden.In this known method, the reservation of the black is therefore possible as well as the reduction of the vat dye in a single operation, your steaming, in front of you. The use of strong alkalis in this process has the disadvantage that it is not only in the steam that unpleasant-looking white halos surround the colored etching effects form around, probes there are also the applied vat dyes by no means completely fixed on the fiber, so that pale, unsightly colored effects are achieved will.

Die Übelstände sind nach der Erfindung dadurch vermieden, daß die Reservierung der Entwicklungsfarbe und die Entwicklung des Küpenfarbstoffes in zwei Arbeitsvorgängen nacheinander vorgenommen werden. Bei dieser Unterteilung des Verfahrens wird einerseits wie bisher die Entwicklung des Schwarz an den bedruckten Stellen verhindert, anderseits der Küpenfarbstoff vollkommen auf der Faser fixiert, ohne daß sich weiße Höfe um die Buntätzeffekte herum bilden. Es gelingt also, einwandfreie, satte Bunteffekte herzustellen.The drawbacks are avoided according to the invention in that the Reservation of developing color and development of vat dye in two Operations are carried out one after the other. With this subdivision of the procedure On the one hand, as before, the development of black in the printed areas prevents, on the other hand, the vat dye is completely fixed on the fiber, without that white courtyards are formed around the colored ink effects. So it succeeds, flawless, create rich colorful effects.

Das Verfahren wird folgendermaßen durchgeführt: Die in Anilinschwarzklotzbrühe wie üblich imprägnierte und getrocknete Ware wird mit einer Druckfarbe bedruckt, welche außer clen zur Reservierung des Schwarz erforderlichen Körpern, wie Sulfite, essigsaure und ameisensaure Salze, Karbonate u. dgl., noch Sulfoxylate, dann Eisenvitriol, Zinnsalze. Traubenzucker u. dgl. neben dem zur Illuminierung dienenden Küpenfarbstoff enthält. Als Beispiel einer solchen Druckfarbe sei die untenstehende Vorschrift angeführt. B1 a u: 12o g Indanthrenblau R.S.-Tg. (S c h u 1 t z , Farbstofftabellen, 6. Aufl., S. 288, 289), 4o g Indanthrenblau G.C.D.-Tg., 84o g Stammfarbe, 1000 g. Stammfarbe: Zoo g Schlämmkreide, 150 g Brit. Gummi pulv., 3059 Wasser, Zoo g Eisenvitriol, 6o g Zinnoxydul i. Tg. 50 Prozent, a75 g Rongalit C., 1o g Terpentinöl, i ooo g. Man dämpft nun im Schnelldämpfer bis zur genügenden Entw icklung des Schwarz, nimmt die Ware durch ein 70° heißes Bad von Natronlauge 2o° B6, wäscht gut, säuert -schwach und passiert zuletzt noch ein schwach alkalisches Bad, worauf nochmals gewaschen und dann getrocknet wird.The process is carried out as follows: The goods, impregnated in aniline black block broth and dried as usual, are printed with a printing ink which, in addition to the substances required to reserve the black, such as sulfites, acetic and formic salts, carbonates and the like, also sulfoxylates, then iron vitriol , Tin salts. Contains glucose and the like in addition to the vat dye used for illumination. The rule below is given as an example of such a printing ink. B1 au: 12o g indanthrene blue RS-Tg. (S chu 1 tz, Dye Tables, 6. Ed., Pp. 288, 289), 4o g indanthrene blue GCD-Tg., 84o g trunk color, 1000 g. Trunk color: Zoo g whipped chalk, 150 g Brit. Rubber powder, 3059 water, Zoo g iron vitriol, 6o g tin oxide i. Day 50 percent, a75 g Rongalit C., 1o g turpentine oil, i ooo g. Steam is now in the high-speed steamer until the black has developed sufficiently, the goods are taken through a 70 ° hot bath of sodium hydroxide solution 20 ° B6, washed well, weakly acidified and finally passed through a weakly alkaline bath, which is then washed again and then dried .
