Description

The invention relates to uniformly dyed water-swellable cellulosic fibers which are fast to washing, dry-cleaning, sublimation and light and have been produced by contacting water-swellable cellulose fibers sequently or concomitantly with water, ethylene glycol or a derivative thereof and, while the fibers are still swollen, an essentially water-insoluble dye of the formula ##STR2## IN WHICH D is the radical of a diazo component;

R is hydrogen, C.sub.1 to C.sub.7 alkyl, phenyl or phenyl bearing methyl as a substituent; X is cyano, carbamoyl or substituted carbamoyl; R.sup.1 is hydrogen or an aliphatic, cycloaliphatic, araliphatic or aromatic radical; R.sup.2 is hydrogen or an aliphatic, cycloaliphatic or araliphatic radical; R.sup.3 and R.sup.4 independently of one another have the same meanings as R.sup.1 and R.sup.2 ; and R.sup.1 --n--r.sup.2 and R.sup.3 --N--R.sup.4 independently of one another are saturated heterocyclic radicals.

The radical D may be derived particularly from an amine of the benzene, naphthalene, benzothiazole, benzoisothiazole, thiazole, thiadiazole, indazole, pyrazole, thiophene, azobenzene, phthalimide, naphthalimide or anthraquinone series.

Examples of substituents of the radical of the diazo component D are: in the benzene series: fluoro, chloro, bromo, nitro, cyano, trifluoromethyl, methylsulfonyl, ethylsulfonyl, phenylsulfonyl, carboxylic esters such as C.sub.1 to C.sub.8 alkoxycarbonyl, phenoxycarbonyl, phenoxyethoxycarbonyl or .beta.-C.sub.1 to .beta.-C.sub.4 alkoxyethoxycarbonyl, optionally N-monosubstituted or N,N-disubstituted carbamoyl or sulfamoyl, methyl, ethyl, butyl, octyl, hexyl, methoxy or ethoxy and also carboxy. N-substituents of carbamoyl or sulfamoyl are for example methyl, ethyl, phenyl, benzyl, phenylethyl, cyclohexyl, norbornyl, propyl, butyl, .beta.-hydroxyethyl, .gamma.-hydroxypropyl, .beta.-methoxyethyl, .gamma.-methoxypropyl, .gamma.-ethoxypropyl and also pyrrolidide, piperidide and morpholide.

In the azobenzene series: fluoro, chloro, bromo, nitro, cyano, trifluoromethyl, methyl, ethyl, carboxy, methoxy and ethoxy, the carboxylic esters, carbamoyl and sulfamoyl radicals referred to under the benzene series, and hydroxy.

Dyes of the formula (I) may be prepared by reacting a diazo compound of an amine of the formula (II):

d--nh.sub.2 (ii) with a coupling component of the formula (III): ##STR20## in which D, R, X, and R.sup.1 to R.sup.4 have the above meanings.

The amines are diazotized by the usual methods. Coupling is also carried out as usual in an aqueous medium, with or without the addition of a solvent, at a strongly acid to weakly acid pH.

The substituents are conveniently chosen so that the molecule contains either in the diazo component or in the coupling component at least one aryl radical and preferably a phenyl radical.

We have special preference for A to be methyl and X.sup.1 to be cyano and also for the combination A.dbd.H and X.sup.1 =CONH.sub.2.

The dyes of the formula (I) may from their constitution be termed disperse dyes whose application for example to cotton is not as a rule possible. A process is described however in U.S. Pat. No. 3,706,525 which makes printing on cellulose and cellulosic textile material possible. Details given therein concerning process conditions are applicable to the dyes of the present invention. Other methods are specified in our copending application Ser. No. 691,496 according to which the dyes according to formula I may be applied. Printing processes are preferred. The above patent and application are incorporated herein by reference.

The dyes according to formula I give dyeings and prints having excellent fastness properties among which wet fastnesses (particularly fastness to washing, water, perspiration and sea water) and in some cases lightfastness may be emphasized. In the case of prints for example no staining of any white ground present occurs in washing.

In the following Examples, which illustrate the invention, parts and percentages are by weight unless specified otherwise.

EXAMPLE 1

Cotton cloth is printed by a rotary screen printing method with an ink consisting of 10 parts of the dye of the formula: ##STR27## 100 parts of polyethylene oxide of a molecular weight of 300 to 790 parts of a 3% alginate thickening and the print is dried at 100.degree. C. The print is then treated for one minute at 200.degree. C. with hot air, rinsed cold, soaped at the boil, again rinsed cold and dried. A light-fast and wash-fast yellow orange print is obtained on a white ground.

EXAMPLE 2

A cloth from a blend of polyester and cotton (ratio by weight 67:35) is printed with a paste consisting of 20 parts of the dye of the formula ##STR28## 120 parts of the reaction product from polyethylene oxide having a molecular weight of 300 with boric acid in the molar ratio 3:1 and 860 parts of a 10% alginate thickening. The print is dried at 105.degree. C. and treated for six minutes at 180.degree. C. with superheated steam. The print is then rinsed with cold water, soaped at 80.degree. C., again rinsed cold and dried.

A red print which is fast to light and washing is obtained on a white ground.

EXAMPLE 3

A cotton cloth is printed by the roller printing method with a print paste consisting of 15 parts of the dye of the formula: ##STR29## 110 parts of polyethylene oxide of the molecular weight 350, 30 parts of the diethanolamide of oleic acid and 845 parts of a 10% alginate thickening. The print is dried at 100.degree. C. and then fixed by a treatment with hot air for one minute at 195.degree. C. The print is finished off as described in Example 1 and a fast orange print is obtained on a white ground.

EXAMPLE 4

Cloth of a blend of polyester and cellulose (ratio by weight 67:35) is printed on a screen printing machine with an ink consisting of 30 parts of the dye of the formula: ##STR30## 100 parts of the reaction product of polyethylene oxide of the molecular weight 300 with boric acid in the molar ratio 3:1, 30 parts of the diethanolamide of oleic acid and 840 parts of a 3% alginate thickening and the print is dried at 110.degree. . It is then treated for five minutes at 185.degree. C. with superheated steam and finished off as described in Example 2. A fast scarlet print on a white ground is obtained.

EXAMPLE 5

Cotton cloth is padded on a padding mangle with a solution containing 20 parts of the dye of the formula: ##STR31## 300 parts of a 3% alginate thickening, 550 parts of water and 130 parts of polyethylene oxide of the molecular weight 300. The cloth should take up 80% liquor. It is dried at 100.degree. C. To fix the dye it is treated for five minutes with superheated steam at 190.degree. C. The cloth is then rinsed cold, washed at 90.degree. C. in a liquor containing 3 parts of the condensation product of a long chain alcohol with ethylene oxide to 997 parts of water.

A yellow dyeing is obtained.

Cloth of a blend of polyester and cotton in the ratio by weight 67:33 may be padded with the said solution instead of cotton cloth. A yellow dyeing is obtained in which the two phases are equal in tone. Fixation with hot air at 195.degree. C. may also be carried out instead of the treatment with superheated steam.

EXAMPLE 6

Cotton cloth is padded on a padding mangle with a solution of 150 parts of polyethylene oxide in 850 parts of water so that the wet pickup is 80% and the padded cloth is dried at 100.degree. C. The cloth treated in this way is printed by the rotary screen printing method with a color consisting of 30 parts of the dye of the formula: ##STR32## and 970 parts of a 10% alginate thickening. After the print has been dried at 105.degree. C. it is treated for seven minutes at 185.degree. C. with superheated steam and finished off by rinsing and soaping as described in Example 1.

A fast red print on a white ground is obtained.

The dyes specified in the following Examples may be converted as follows into a commercial dye formulation:

30 parts of dye, 6 parts of dispersing agent, 10 parts of a water retention agent, 1 part of a disinfectant and about 53 parts of water are ground in an agitator mill to a particle size of about 0.5 micron. A dispersion of the dye is thus obtained which is stable in storage.

EXAMPLE 7

20 Parts of 4-aminoazobenzene is stirred overnight with 80 parts by volume of 5 N hydrochloric acid. Then it is diluted with ice and water to a volume of 500 parts by volume at 10.degree. C. 30 parts by volume of a 23% sodium nitrite solution is added and the whole is stirred for two hours at 15.degree. C. The filtrate, in which excess nitrous acid has been removed in the conventional manner by adding sulfamic acid, is allowed to flow into a solution of 53 parts of 2,6-bis(phenoxyethoxypropylamino)-3-cyano-4-methylpyridine in 4000 parts by volume of dimethylformamide at 15.degree. C. 150 parts by volume of a 50% aqueous sodium acetate solution is then added to this coupling mixture and the whole is stirred at 15.degree. C. until coupling is completed. The dye formed is suction filtered, washed first with alcohol and then with hot water and dried at 90.degree. C. A red powder is obtained which readily dissolves in dimethylformamide and polyethylene glycols with a yellowish red color and when printed in the form of these solutions or as an aqueous dispersion on cloth of polyester or cotton or a blend of the two types of fiber and aftertreated with hot air or superheated steam gives deep and clear scarlet hues.

EXAMPLE 8

35 parts of 3-chloro-4-aminoazobenzene is stirred overnight with 7 parts of an oxyethylated sperm oil alcohol containing about 23 ethylene oxide radicals and 120 parts by volume of 5 N hydrochloric acid. A volume of 750 parts by volume and a temperature of 10.degree. C. are set up with ice and water and 450 parts by volume of a 23% aqueous sodium nitrite solution is introduced. After stirring for two hours at 15.degree. C. a small amount of insoluble matter is filtered off and nitrous acid is removed in the usual way by adding an aqueous solution of sulfamic acid.

The diazonium salt solution thus obtained is then allowed to flow at 10.degree. C. into 385 parts by volume of an isobutanol solution containing 0.16 mole of 2,6-bis-(phenoxyethoxypropylamino)-3-cyano-4-methylpyridine. Complete coupling is achieved after stirring for several hours at 15.degree. to 25.degree. C. without adding the usual acid-binding agents. The dye formed is suction filtered, washed first with 100 parts by volume of isobutanol and then with 100 parts of hot water and then dried at 100.degree. C.

The product which is in the form of a red powder may as an aqueous dispersion or dissolved in a polyethylene glycol be printed on cloth of polyester, cotton or a blend of both types of fiber and aftertreated with hot air or superheated steam. Deep and clear red hues of very good light and wet fastness properties are thus obtained.

EXAMPLE 9

The procedure described in Example 8 is adopted but the coupling component used is 0.15 mole of the substance having the formula: ##STR33## dissolved in 8000 parts by volume of dimethylformamide. The red powder obtained after isolation and drying dissolves in dimethylformamide and polyethylene glycols with a yellowish red color. Deep and clear scarlet hues with very good fastness properties are obtained on cloth of polyester, cotton or blends of the two.

Red hues having similar tinctorial properties are obtained in an analogous manner with the same diazo components and the following coupling components:

example 23

16 parts of o-trifluoromethylaniline is dissolved in 30 parts by volume of 10 N hydrochloric acid and 200 parts of water, 200 parts of ice is added and then 30 parts by volume of a 23% aqueous solution of sodium nitrite is allowed to flow in below the surface. After stirring for half an hour at 0.degree. to 5.degree. C. the excess of nitrous acid is destroyed as usual by adding an aqueous solution of sulfamic acid.

The solution of the diazonium salt thus obtained is gradually added at 5.degree. to 10.degree. C. to a solution of 54 parts of bis-(phenoxyethoxypropylamino)-3-cyano-4-methylpyridine in 1000 parts by volume of dimethylformamide and then 32 parts by volume of a 50% aqueous sodium acetate solution is added. When coupling is over the yellow dye formed is suction filtered, washed first with alcohol and then with hot water and dried at 100.degree. C. The yellow powder thus obtained dissolves in dimethylformamide or polyglycols with a pure yellow color and when printed on to cloth of cotton, polyester or blends of both and fixed gives deep and clear yellow hues with very good fastness properties.

The following dyes are obtained in a similar manner with the same coupling components:

EXAMPLE 32

25.3 Parts of the p-tolylimide of 3-aminophthalic acid is introduced at 15.degree. to 25.degree. C. into 60 parts of 96% sulfuric acid while stirring. The mixture is further stirred at the same temperature until complete solution has taken place. Then 32 parts (0.1 mole) of nitrosylsulfuric acid is allowed to flow in slowly at 0.degree. to 5.degree. C. and the diazotization mixture is stirred for another thirty minutes at 0.degree. to 5.degree. C. and then introduced into a mixture of 125 parts of ice and 25 parts of ice-water.

After the excess of nitrite has been destroyed with sulfamic acid the diazonium salt is stirred while 300 parts by volume of isobutanol and 110 parts by volume of a 10-molar solution of 2,6-bis(phenoxyethoxypropylamino)-3-cyano-4-methylpyridine in isobutanol are introduced. After coupling is over the dye formed is suction filtered, washed first with isobutanol and then with hot water and dried at 100.degree. C. The reddish powder thus obtained dissolves in polyglycols with a reddish yellow color and gives deep orange hues with very good fastness properties on polyester, cotton or blends of the two after having been printed and fixed.

The following dyes may be obtained by similar methods with the same coupling components:
