Description

Verfahren zum gleichstarken Färben von verschiedenartigem, Baumwolle enthaltendem Fasermaterial Beim Färben von Fasermaterial, das aus verschiedenartigen Fasern besteht, z. B. beim Färben von Reißwolle mit Schwefelfarbstoffen, welche wasserlöslichmachende Gruppen enthalten, wird es zuweilen störend empfunden, daß der Baumwollanteil des Fasermaterials, besonders wenn er in höheren Anteilen vorliegt, im harbtcm heller ausfällt als der Woll- und Zellwollanteil.Process for dyeing different types of cotton of the same thickness containing fiber material When dyeing fiber material, which consists of various Consists of fibers, e.g. B. when dyeing shredded wool with sulfur dyes, which contain water-solubilizing groups, it is sometimes found disturbing that the cotton content of the fiber material, especially if it is present in higher proportions, in the harbtcm is lighter than the wool and cellulose wool content.

Es wurde nun gefunden, daß diese als Mangel empfundene Erscheinung behoben werden kann, wenn inan (las gemischte Fasermaterial vor dem Färben mit Schwefelfarbstoffen, welche wasserlöslichmachende Gruppen enthalten, mit Peralkylierungsprodukten von :@lkyleniminpolymerisaten behandelt.It has now been found that this phenomenon was perceived as a defect can be remedied if inan (read mixed fiber material before dyeing with sulfur dyes, which contain water-solubilizing groups, with peralkylation products of : @lkylenimine polymers treated.

Durch diese Vorbehandlung wird der Baumwollanteil in der Affinität für die genannten Farbstoffe dein Woll- und Zellwollanteil weitgehend angeglichen; infolgedessen werden Baumwoll-, Woll- und Zellwollanteil praktisch gleich tief gefärbt. Daraus geht also hervor, (laß die Peralkylierungsprodukte von Alkyleniminpolymerisaten eine faserauslesende Wirkung besitzen, die erfindungsgemäß verwertet wird.This pretreatment increases the affinity of the cotton content for the dyes mentioned, your wool and cellulose wool content largely matched; As a result, cotton, wool and cellulose wool are dyed practically the same depth. It follows from this that (leave the peralkylation products of alkylenimine polymers have a fiber-extracting effect which is utilized according to the invention.

Beispiel i ioo g eines Gemisches von Wolle, Baumwolle und Zellwolle werden mit 0,2 g des Permethylierungsproduktes eines Äthyleniminpolymerisates (hergestellt durch erschöpfende Methylierung eines Äthyleniminpolymerisates mittels Dimethylsulfat) 2o bis 30 Minuten bei 4o bis 5o° behandelt.EXAMPLE 100 g of a mixture of wool, cotton and rayon are treated with 0.2 g of the permethylation product of an ethyleneimine polymer (prepared by exhaustive methylation of an ethyleneimine polymer using dimethyl sulfate) for 20 to 30 minutes at 40 to 50 °.

Hierauf werden 12 g des schwarzen Schwefelfarbstoffs, erhalten durch Polysulfidschmelze von 2, 4-Dinitrophenol und nachträgliche Behandlung des Schwefelungsproduktes mit oxydativen Mitteln, in Wasser angeteigt und mit 12 g Natriumformaldehydsulfotylat (Schultz, Farbstofftabellen, 1932, Bd.II, S.295), 5 g 25°/otgem Ammoniak und 0,5 g ölsäureamidosulfonsaurem Natrium (Schultz, Farbstofftabellen, 1932, Bd. II, S. 310) zu einer Färbeflotte gelöst. Bei einer Färbebadtemperatur von 4o bis 50° färbt man in diesem Bade ioo g des wie oben vorbehandelten Fasergemisches, wobei man die Temperatur in etwa 20 Minuten auf 85 bis 9o° bringt und weitere 20 Minuten auf dieser Temperatur hält. Dann setzt man 20 g calc. Glaubersalz zu und färbt abermals 20 Minuten bei der gleichen Temperatur. Die so gefärbte Ware wird in kaltem Wasser gespült und bei 40° mit Ameisensäure oder Essigsäure io Minuten abgesäuert. Dann wird wieder gut gespült, geschleudert und getrocknet.Then 12 g of the black sulfur dye, obtained by polysulphide melt of 2,4-dinitrophenol and subsequent treatment of the sulphurisation product with oxidative agents, are made into a paste in water and mixed with 12 g of sodium formaldehyde sulfotylate (Schultz, Farbstofftabellen, 1932, vol. II, p.295), 5 g of 25% ammonia and 0.5 g of sodium oleic acid amidosulfonic acid (Schultz, dye tables, 1932, vol. II, p. 310) dissolved to form a dye liquor. At a dyebath temperature of 40 to 50 °, 100 g of the fiber mixture pretreated as above are dyed in this bath, the temperature being brought to 85 to 90 ° in about 20 minutes and held at this temperature for a further 20 minutes. Then 20 g calc. Add Glauber's salt and dye it again for 20 minutes at the same temperature. The goods dyed in this way are rinsed in cold water and acidified at 40 ° with formic acid or acetic acid for 10 minutes. Then it is rinsed well, spun and dried again.

Man erhält so eine Schwarzfärbung von praktisch gleicher Stärke auf der in dem Fasergemisch enthaltenen Baumwolle, Wolle und Zellwolle.A black coloration of practically the same strength is thus obtained the cotton, wool and rayon contained in the fiber mixture.

Beispiel 2 Ersetzt man in obigem Beispiel den schwarzen Schwefelfarbstoff durch io g des blauen Schwefelfarbstoffs, der nach der Patentschrift 137 784 durch Schwefelung von 2, 4-Dinitro-4 -oxvdiphenylamin und nachfolgende Oxydation erhalten wird, und arbeitet im übrigen in analoger Weise, wie in Beispiel i beschrieben ist, so erhält man eine tiefe blumige Blaufärbung, die auf der Baumwolle praktisch die gleiche Tiefe wie auf der Wolle und Zellwolle zeigt.EXAMPLE 2 In the above example, the black sulfur dye is replaced by 10 g of the blue sulfur dye which, according to Patent Specification 137 784, is obtained by sulphurisation of 2,4-dinitro-4-oxydiphenylamine and subsequent oxidation, and the procedure is otherwise analogous to how is described in Example i, the result is a deep, floral blue coloration which shows practically the same depth on the cotton as on the wool and rayon.
