Definitions
- the cationic dyestuffs may form addition compounds with the anionic dispersing agents used for disperse dyestuffs which may cause precipitation of the disperse dyestuff in the padding liquor, resulting in a distinct loss of colour yield and in uneven and specky dyeings.
- non-ionic dispersing agents there may be used according to the invention either polyglycols, oxyethylated oxazoline derivatives or oxalkylated fatty acid derivatives or mixtures of these products.
- polyethylene glycols having an average molecular weight in the range of from 1500 to 8000, especially those having a molecular weight of about 6000.
- oxalkylated fatty acid derivatives there may be used according to the invention products which are derived from fatty amines, fatty acid amides or fat alcohols, preferably the oxethylation products of fat alcohols and fatty amines having polyether chains that correspond to 12 to 25 mols of ethylene oxide or mixtures of these compounds having a different degree of oxethylation, the reaction products of 1 mol of stearyl alcohol and 25 mols of ethylene oxide or of 1 mol of oleyl alcohol and 22.5 mols of ethylene oxide or of 1 mol of stearyl alcohol and 12 mols of ethylene oxide showing the most favourable behaviour.
- the reaction prod not of 1 mol of 2-heptadecyl-4-ethyl-4-hydroxymethyl-oxazoline and 70 mols of ethylene oxide is preferably used.
- 20 to 40 g., preferably 25 to 35 g., of non-ionic dispersing agent are added per liter to the padding liquor.
- disperse dyestuffs there may be used according to the invention the dyestuffs usually employed for the dyeing of fibrous materials of linear polyesters, for example those of the series of azo or anthraquinone dyestuffs.
- Disperse dyestuffs of said type are known, for example, from Colour Index, second edition (1956), vol. 1, pages 1659- 1742 and Supplement (1963), pages S 179-S 22-4 as well as from the corresponding Additions and Amendments No. 1 (September 1963) to No. 26 (January 1970).
- cationic dyestuffs used according to the invention there may be especially mentioned those of the series of azo, azomethine, methine, anthraquinone, nitro, diand triphenylmethane, phenazine, oxazine, thiazine, xanthene and quinophthalone dyestuffs.
- Suitable cationic dyestuffs are described in Colour Index, second edition (@1956), vol. 1, pages 1617-1653 and in Supplement (1963), pages S 149-8 177 as well as in the corresponding Additions and Amendments No. 1 (September 1963) to No. 26 (January 1970).
- organic acids for example acetic acid and formic acid, preferably acetic acid.
- the process of the invention is carried out by applying onto the textile material of polyester and polyacrylonitrile fibers an aqueous preparation having a temperature of from 20 to 40 C., preferably 30 C. and containing, in addition to dispersed disperse dyestuffs and dissolved cationic dyestuffs, free acid and non-ionic dispersing agents.
- the cationic dyestuff is first pasted up with the acid and dissolved by the addition of boiling hot water. After cooling to 20 to 40 C., this solution is added to an aqueous dispersion of the disperse dyestuffs having a temperature in the range of from 20 to 40 C. and to which a mixture of non-ionic agents had previously been added.
- the wet mixed material is dried at a temperature in the range of from to 130 0., preferably at C., and then subjected to a heat treatment for 30 to 90 seconds, preferably 60 seconds, at 180 to 210 C., preferably at 200 C., by means of hot air, superheated steam, a mixture of heated air and superheated -steam or on heated cylinders, during which time the disperse dyestutf is fixed onto the polyester fiber and the cationic dyestufl is fixed onto the polyacrylonitrile fiber.
- This heat treatment simultaneously fixes the polyester portion of the mixed material and imparted its optimal technological properties.
- the goods are rinsed and soaped and further treated in the usual manner.
- the textile material to be dyed according to the present invention which consists of mixtures of linear polyesters,
- polyethylene terephthalate, and polyacrylonitrile fibers may have the form of a yarn, fabric or knitted fabric.
- the cellulose fiber portion of the goods is dyed with dyestuffs of the classes usually employed for cellulose fibers, especially reactive dyestufis, according to the methods known for these purposes, after the heat treatment, without/ or after previous intermediate cleaning.
- the dyestuffs used in this further embodiment of the process of the invention are, preferably, such organic compounds which contain at least one group capable of reacting with the cellulose fiber, a precursor for such a group or a substituent capable of reacting with the cellulose fiber.
- the parent components of these dyestuffs may belong to difierent classes of compounds; particularly suitable are those of the series of the anthraquinone, azo and phthalocyanine dyestuffs; the azo and phthalocyanine dyestuffs may be metal-free or metalliferous.
- the reactive groups and precursors, which form such reactive groups in an alkaline medium are, for example epoxy-groups, the ethyleneimide group, the vinyl group within the vinyl-sulfoneor acrylic acid radical, furthermore the ,B-sulfato-ethyl-sulfonyl group, the B-chloroethyl-sulfonyl group, the B-thiosulfato-ethyl-sulfonyl group, the fi-phosphatoethyl-sulfonyl group.

- a mixed fabric consisting of polyethylene terephthalate and then subjected for 60 seconds to a treatment with hot fibers and polyacrylonitrile fibers in a ratio of :50 was air at 200 C.
- the dyeing was then completed in the padded on the foulard with a squeezing eifect of 50% 35 usual manner.
