Description

Verfahren zum Durchfärben dichter Gewebe aus Fasern pflanzlichen Ursprungs Das Färben dichter Materialien mit Küpenfarbstoffen, indem das Material zuerst mit dem fein verteilten unverküpten Farbstoff imprägniert wird und indem hierauf zwecks Fixation des Farbstoffes das imprägnierte Material mit geeigneten Reduktionsmitteln und Oxydationsmitteln nacheinander behandelt wird, ist altbekannt (vgl. Patentschrift 177952).Process for through-dyeing dense fabrics made of fibers of vegetable origin Dyeing dense materials with vat dyes by using the material first is impregnated with the finely divided, unlinked dye and by using it for the purpose Fixation of the dye to the impregnated material with suitable reducing agents and oxidizing agents are treated one after the other is well known (see patent specification 177952).

In neuester Zeit wurde gezeigt (vgl. die französische Patentschrift 668 638), daß dieses Verfahren besonders dann glatt verläuft, wenn dem Imprägnierungsbade sog. Fließmittel, wie Emulsionen von Fetten und Ölen bzw. ihren freien Säuren oder wasserlöslichen Derivaten, wie Türkischrotöl usw, ferner Gellulosederivate, die in Wasser neutral oder alkalisch kolloidale Lösungen zu bilden imstande sind, wie besonders das Alkalisalz der Carboxymethylcellulose, zugesetzt werden. Dagegen ist in derselben Patentschrift ausdrücklich erwähnt, daß die bekannten bewährten Netzmittel nur mangelhafte Resultate geben.Recently it has been shown (cf. the French patent specification 668 638) that this process runs particularly smoothly when the impregnation bath so-called flow agents, such as emulsions of fats and oils or their free acids or water-soluble derivatives, such as Turkish red oil, etc., and also gelulose derivatives, the are able to form neutral or alkaline colloidal solutions in water, such as especially the alkali salt of carboxymethyl cellulose can be added. Against it is expressly mentioned in the same patent that the well-known tried and tested wetting agents only give poor results.

Es wurde nun gefunden, daß,entgegen diesen Angaben, bewährte Netzmittel, nämlich die alkylierten bzw. aralkylierten oder cycloalkylierten Sulfonsäuren der Naphthalinreihe, welche bekanntlich wertvolle Netzmittel darstellen, ebenfalls das Färben von dichtem Material nach den obenerwähnten Verfahren, als Zusatz zum Farbstoffbade, die Erzielung von gut durchgefärbten Färbungen. vorzüglich unterstützen. Hierzu eignen sich besonders z. B. Isopropyl- und Diisopropyl-, Butyl- und Dibutylnaphthalinsulfonsäuren. Solche Mittel wirken bedeutend besser als die in der französischen Patentschrift 668 638 genannten Hilfsstoffe, z. B. Türkischrotöl oder Carboxymethyloellulose. Beis piel Man bestellt ein Klotzbad mit 5o g Cibanonblau 3 G dopp. Teig (vgl. S c h u 1 t z, Farbstofftabellen, 6. Auflage, 19223, Nr. 793) und 12 g des Natriumsalzes der Dibutylnaphthalinsulfonsäure. Diese Farbstoffaufschlemmung dient als Imprägnierungsflotte für das durchzufärbende Material. Das Gewebe wird mehrmals durch diese Flotte gezogen und zwischendurch durch Quetschwalzen ab;gepreßt. Hierauf wird das Gewebe auf ein frisches. Bad genommen, welches Lauge und Hydrosulfit in der üblichen Konzentration @enthält (z. B. 16 ccm 3oprozentige Natronlauge und 2 g Natriumhydrosulfit je Liter) und bei 6o° C behandelt. Sodann wird in bekannter Weise oxydiert und fertiggemacht. Die Durchfärbung des Gewebes ist vorzüglich.It has now been found that, contrary to this information, proven wetting agents, namely the alkylated or aralkylated or cycloalkylated sulfonic acids of Naphthalene series, which are known to be valuable wetting agents, also do that Dyeing of dense material according to the above-mentioned methods, as an addition to the dye bath, the achievement of well-dyed colorations. excellent support. For this are particularly suitable for. B. isopropyl and diisopropyl, butyl and dibutylnaphthalenesulfonic acids. Such agents work significantly better than those in the French patent 668 638 mentioned auxiliaries, e.g. B. Turkish red oil or carboxymethyloellulose. Example You order a block bath with 50 g cibanon blue 3 g double dough (see p c h u 1 t z, color tables, 6th edition, 19223, no. 793) and 12 g of the sodium salt of dibutylnaphthalenesulfonic acid. This dyestuff suspension serves as the impregnation liquor for the material to be colored. The fabric is pulled through this liquor several times and in between by squeezing rollers; pressed. Thereupon the tissue is turned on fresh. Bath taken, which lye and hydrosulfite in the usual concentration @ contains (e.g. 16 ccm 3% sodium hydroxide solution and 2 g sodium hydrosulphite per liter) and treated at 60 ° C. Then it is oxidized and finished in a known manner. The coloration of the fabric is excellent.
