(Cl. 8-55) This application is a continuation-in-part of our pending application Ser. No. 333,261, filed Dec. 23, 1963, now abandoned.

This invention relates to a process for the continuous pad-dyeing of natural and synthetic polyamide and other textile fibers, as well as pad liquors and novel carriers suitable for use in this process.

It is known that polyamide fibers can be pad-dyed by continuous processes. A known process of this type comprises impregnating wool with an aqueous, thickened solution of acid wool dyestuffs (pad liquor) at temperatures below the drawing temperature of these dyestuffs, then drying the goods and fixing the dyestuif by passing the goods through a hot acid bath (so-called acid shock), and rinsing. As this process has proved to have serious disadvantages, for instance, by producing uneven dyeings, it has not gained practical importance.

As a further development of this process, it has already been suggested to add carriers to the impregnation liquor. As such, the condensation products of fatty acids having 8 to 14 carbon atoms or mixtures of such acids and 2 equivalents of dialkanolamine have proved to be the best. Such condensation products are obtained by the process described in U.S. Patent 2,089,212.

However, the use of these improved impregnating liquors still has a number of drawbacks, the main one being that they are not stable. After a few hours, without any apparent exterior cause, they often separate irreversibly into two phases, one poor in auxiliaries and the other rich therein, the latter containing the main amount of dyestuif. This phase separation in the impregnating liquor makes the uniform dyeing, particularly of large batches, more difiicult. In order to prevent phase separation in the dye liquor it is necessary to calculate carefully the ratio of dyestuif, electrolyte and auxiliaries to each other which makes the constancy of performance of the process considerably more diflicult and adversely affects its eifective range of application.

In order to prevent this undesirable phase separation in the dye liquor, it has also been proposed to introduce into the liquor used for padding wool and the like polyamides soluble salts of saturated aliphatic monocarboxylic acids having 8 to 14 carbon atoms, or polyglycol ethers of alkanols having 8 to 14 carbon atoms or of fatty acids having 4 to 12 ether groups, or by using the condensation products of fatty acids and dialkanolamine mentioned above according to U.S. Patent 2,089,212 together with non-foaming, anion-active dispersing agents such as tetrahydronaphthalene sulfonic acid. However, the stable pad-liquors thus obtained require a pH above 5.0 and preferably a neutral to alkaline pH range in order to remain homogeneous. This is disadvantageous for the dyeing of polyamide fibers and particularly of wool, and undesirable because it excludes the use of certain commercially valuable wool dyestuffs which require after-chrom- 'ice ing in a pH range below 5.0 such as Eriochrome Black It is, therefore, the main object of this invention to provide a continuous process for the pad-dyeing of natural polyamide fibers, especially wool or synthetic polyamide fibers, in a wide pH range embracing also acid pH values as low as 2.

The process according to the invention comprises:

(I) impregnating the said polyamide fibers with an aqueous pad-liquor which contains, as essential constituents, an amount of 5 to grams, and preferably 20 to 40 grams, per liter of liquor, of a dyestutf carrier according to the invention as defined in detail below; noncationic dyestulf capable of drawing on the above-listed fibers from a pad liquor of a. pH ranging from 2 to 10; and, optionally, as a clarifying agent, especially isopropa- 1101 or a ,B-alkoxy-ethanol of a total of from 3 to 8 carbon atoms, such as B-methoxyethanol, B-ethoxyethanol or fihexoxyethanol, or mixtures of isopropanol and the aforesaid alkoxy-ethanols, said impregnation being carried out at a temperature below the drawing temperature of the respective dyestuifs being used and at a pH of about 2 to 10, and

(II) fixing the dyestuif in the treated goods by a heat treatment in a humid medium, preferably without intermediate drying, by treating the goods with hot steam and/or passing them through a hot acid bath.

According to the invention, the above-mentioned dyestuif carrier, upon the composition of which the successful dyeing according to the invention depends, consists essentially of a mixture of (A) an unsulfated amide or a mixture of unsulfated amides of a substantially saturated aliphatic monocarboxylic, i.e., fatty acid from 10 to 14 carbon atoms in the lipophilic radical, which fatty acid may also be substituted by higher alkyl-phenoxy wherein the higher alkyl moiety has from 8 to 12 and preferably 9 carbon atoms, or of a mixture of such fatty acids of from 8 to 14 carbon atoms which mixture of acids has preferably an average number of more than 10, and preferably 12 carbon atoms, amidified with primary or sec ondary amines containing at least one hydroxy-lower alkyl group which may be etherified; more specifically, unsulfonated amides defined under (A) supra, which can be used in the pad liquors according to the invention are derived from, for example, caprylic, pelargonic, capric, lauric or myristic acid, or, preferably, from the acid mixture of fatty acids obtained from coconut oil, or from lower fatty acids substituted by alkylphenoxy radicals, in particular alkylphenoxy-acetic acids, wherein the alkyl moiety has from 8 to 12 and preferably 9 carbon atoms, e.g., octylor nonyl-phenoxy-acetic acid, and the following aliphatic amines:

(a) from monoand di-hydroxy-alkylamines such as ,B-hydroxyethylamine, 'y-hydroxypropylamine, ,8,'ydihydroxy-mono-propylamine;

(b) from bis-(hydroxyalkyl)-amines preferably of a total of from 4 to 6 carbon atoms such as bis-(flhydroxyethyl) amine, bis ('y hydroxypropyl)- amine, bisa-methyl-fi-hydroxyethyl) -amine;

(c) from N-alkyl-N-(hydroxyalkyl)-amines, preferably N-methyl-N-w-hydroxyalkylamines of from 3 to 4 carbon atoms, or the corresponding N-ethylsubstituted amines of from 4 to 5 carbon atoms such as N-methylor N-ethyl-N-(,B-hydroxyethyD- amine, or N-methylor N-ethyl-N-(y-hydroxypropyl)-amine;

(d) from amino-lower alkyl ethers, especially mono- (w-alkoxy-alkyD-amines of a total of from 3 to 5 carbon atoms, at least two of which pertain to the 3 alkyl moiety, such as B-methoxyor fi-ethoxyethylamine or v-methoxyor 'y-ethoxypropylamine;

(B) sulfated, surface-active organic polyglycol ether or a soluble salt thereof, which polyglycol ether is the condensation product of an alkanol or a higher alkyl phenol with ethylene oxide or propylene oxide in molar ratios ranging from 1 to 20, the terminal hydroxy group of which condensation product has been sulfated, such sulfated polyglycol ether being more in particular (i) a sulfated condensation product of an alkancl of 8 to 14 carbon atoms, with ethylene oxide condensed with each other in a molar ratio of from 1:1 to 1:20, and preferably from 1:2 to 1:5,

(ii) a sulfated condensation product of alkylphenol, the alkyl moiety of which has from 8 to 12 carbon atoms, with ethylene oxide, in a molar ratio of from 1:1 to 1:20, and preferably 1:2 to 1:3, e.g., sulfated glycol ethers of octyl phenol or nonyl phenol, or

(iii) an alkali metal, ammonium lower alkylammonium or w-hydroxy-lower alkylammonium salt of (i) Or (ii).

The ratio of acid amides (A) to the sulfated polyglycol ethers (B) ranges from about 2:1 to 1:2, and preferably 3:2 to 1:15, and, when the above-mentioned clarifying agent is present in order to ensure homogeneity of the carrier mixture for a period of several months and even a year or more, the proportions by weight of (A) to (B) also range from about 2:1 to 1:2, and preferably 3:2 to 1:15, and the content of said clarifying agent ranges from 4 to 20% by weight, calculated on the total weight of said mixture.

Of course, the pad liquors can also be prepared, shortly prior to use, from the individual constituents (A) and (B) of the above-described carrier mixture in the proportions given, in which case the addition of component (C), the clarifying agent is superfluous. In this case, the amide (A) is heated to render the same readily flowing and is added with stirring to an aqueous solution of the constituent (B).

The addition of isopropanol assists flowability of the carrier mixture, but does not affect the color depth of the dyeing obtained in the process according to the invention.

As components (A) in the mixtures the bis-(hydroxyalkyl)-amides, mainly those having hydroxyalkyl radicals containing two or three carbon atoms are preferred, such as bis-(fi-hydroxyethyl)-amides or bis-('y-hydroxypropyl) amides of the fatty acids described above, because they produce good color yields.

The amides described under (A) above are obtained by reacting the esters of suitable fatty acids with lower alkanols, e.g., reacting the fatty acid methyl or ethyl ester with the desired amine in the presence of sodium or potassium alcoholate, for example, by one of the processes described in British Patent N0. 631,367.

Sulfated polyglycol ethers of lauryl alcohol having, in particular, 2 to 3 ether oxygen atoms are preferred as components (B), as these compounds produce particularly level dyeings of good color strength.

The sulfated surface-active polyglycol ether compounds defined under (B) are generally used in the form of their soluble salts; in particular the alkali metal or ammonium salts, but also the alkyl and hydroxyalkyl ammonium salts can be used.

In the dyestutf carriers which are more pronouncedly acid in nature, and particularly in the pad liquors obtained therewith which have a strongly acid pH of 2 to 5, these salts are usually saponified so that the respective free polyglycol ether sulfuric acids, are present therein.

The above-described, sulfated surface-active polyglycol ethers used in preparing the carrier mixture are produced in a conventional manner by first condensing a suitable alkanol or alkylphenol falling under the definition given hereinbefore, with the corresponding number of ethylene oxide moles in the presence of a suitable alkaline catalyst such as sodium ethylate or caustic soda, and subsequent sulfation with chlorosulfonic acid and, finally, neutralization with a suitable cation donor to form the desired salts of the respective sulfated polyglycol ether. Details of the method for producing these compounds are to be found in British Patent 463,624, granted to I. G. Farbenindustrie in 1937, and elsewhere.

Lower when used in this specification in connection with an aliphatic radical means that such radical has from 1 to maximally 4 carbon atoms.

According to one aspect of the invention the dyestuff carrier, the composition of which is an important and critical feature in the process of the invention, consists essentially of a mixture of an unsulfonated amide as defined under (A), supra, and (C) a sulfated amide of an aliphatic monocarboxylic acid, which is optionally substituted and has at least one lipophilic radical, with primary or secondary amines having at least one lower hydroxyalkyl group, and more particularly, sulfated fatty acid mono-B-hydroxyethyl-amides the fatty acid radicals of which have 8 to 14, preferably. 12 carbon atoms (including the COOH group), in particular sulfated coconut oil fatty acid mono-B-hydroxyethyl-amide or sulfated higher alkylphenoxy-substituted fatty acid amides of the above definition, in particular alkylphenoxy acetic acid mono-B-hydroxyethyl-amides or, preferably, alkylphenoxy acetic acid bis-,B-hydroxyethyl amides the alkyl radical of which has 8 to 12, preferably 9 carbon atoms, for example, sulfated nonylp'henoxy acetic acid bis-flhydroxyethylamide, the weight ratio of the sulfated compounds to the non-sulfated compounds being in the range of 5:1 :to 1:5, and preferably from 2:1 to 1:2.

The admixture of such a carrier mixture to an aqueous dyestutf solution or pad liquor allows continuous padding, in particular in the pH-range of 7 to 2.

The sulfated compounds defined under (C) are usually employed in the form of their soluble salts, in particular their alkaline, ammonium, lower alkyl or hydroxy-alkylammonium salts, in the latter case the dior tri-(flhydroxyethyl-amine -salts.

The same stabilizing agents improving the homogeneity and storabili-ty of pad liquors can also be used throughout the instant disclosure in the same proportions as given hereinbefore.

The above-mentioned dyestuif carrier can also consist essentially of an unsulfated amide as defined under (A), supra and (D) a sulfated (alkylphenyl)-(2,3-dihydroxypropyl)-ether the alkyl radical of which has 8 to 12, preferably 9 carbon atoms or a mixture of the sulfated amide mentioned under (C) with a sulfated ether as defined under (D) or of the soluble salts of these sulfated compounds, respectively.

What has been stated hereinbefore with regard to the proportions of carrier components and operating conditions, stabilization of pad liquors, etc., applies equally here.

Sulfated ('alkylphenyl) (2,3-dihydroxypropyl)ethers usable according to the invention are primarily sulfated (nonylphenyl) 2,3-dihydroxypropyl) -ether.

Such ethers are obtained by the reaction of glycol chlorohydrin or l-chloro-2,3-dihydroxy-propane with the corresponding alkylphenols and sulfating the resulting dihydroxy compounds by methods known per se.

Organic fibers which are dyed according to the invention are, among others, polyester fibers such as cellulose dito tri-acet-ate, especially, however, also high-molecular esters of aromatic polycarboxylic acids with polyfunctional alcohols, e.g., polyterephthalic acid glycol esters, or polyurethanes, as well as polymeric and copolyrneric acrylonitrile and methacrylonitrile, polyolefine, chiefly however, synthetic and natural polyarnide fibers such as nylon, Wool or silk.

The capability of the dyestuffs, used in the process of the invention, of drawing on the goods made from the aforesaid fibers can be readily determined by simple routine tests, with which any dyer is familiar.

The process of the invention yields uniform dyeings also with material of great yardage.

The drawing temperature of the dyestuffs used, i.e., the temperature at which the dycstuff draws within about a minute upon the fiber, is usually about 70 C. or more. Impregnating according to the invention has to be effected below this drawing temperature.

Non-cationic dyestuffs capable of drawing on fibers falling under the above-described group under the conditions given, are monoand poly-, preferably dis, azo dyestuffs, namely metal-free, metallizable and heavymetal-containing, in particular chromiurn-, cobalt, nickeland copper complex azo dyes which comprise also the formazane dyes, furthermore, anthraquinone, nitro and methine dyes, acid triphenylmethane and xanthone dyes, naphthazarine dyes and quinophthalone dyes, and also copper phthalocyanine dyes.

To these dyestuffs, there pertain, on the one hand, dyestuffs which are soluble in neutral, acid, or basic medium, within the pH range specified above, and, on the other hand, dyestuffs which are dispersible in water.

As far as the various above-listed textile fibers are concerned, suitable dyestuffs for natural and synthetic polyamide fibers are the so-called acid wool dyes which comprise the above-listed azo, anthraquinone, triphenylmethane and xanthone dyes, and, in particular, also those containing fiber-reactive groups, i.e., so-calied reactive wool and cotton dyes, derived from azo, anthraquinone or phthalocyanine dyes.

Finally, in addition to or instead of dyestuff, the impregnating liquor used in the invention can also contain bactericidal and fungicidal compounds as well as agents which protect against insects, i.e., moth-proofing agents such as the compounds of the formulas SOSH and

which are of the type of known commercial products such as Mitin and Eulan.

For these fibers, and, chiefly for wool, the water-soluble so-called acid wool dyestuffs, particularly also heavymetal-containing, i.e., chromium-, cobaltor copper-containing, azo dyestuffs, including formazane dyestuffs, especially metallized monoazo dyestuffs which contain one metal atom to two molecules of azo dyestuffs are preferred. Chrome dyestuffs are also suitable for these fibers, particularly chromable azo dyestuffs, which latter are used with chromium (III) salts or soluble chromates, preferably in acid medium.

For polyester, polyacrylonitrile and especially modified, in particular vinyl-pyridine-modified copolymers of acrylonitrile and methacrylonitrile fibers as well as polyolefine, in particular polypropylene fibers, there are suitable for use according to the invention azo, anthraquinone, nitro and methine dyestuffs free from water-solubilizing groups, naphthazarine and quinophthalone dyes, while polyurethane fibers as well as synthetic polyamide fibers such as the various types of nylon can be dyed satisfactorily with the aforesaid water-soluble dyestuffs, and also with disperse dyes of the group listed above.

As thickeners, those products which are conventional in textile printing are used, e.g., carob bean flour, galactomannan, tragacanth, dextrin, British gum or-in alkaline medium-also the water-soluble salts of alginic acid. Cellulose derivatives such as methyl cellulose or soluble salts of carboxymethyl cellulose can also be used.

The thickeners must not cause the formation of precipitates in the pad liquor under the conditions of the above-described dyeing method.

Insofar as suitable apparatus is available, the organic fibers to be dyed according to the invention can be in any form desired. For example, they can be in the form of flocks, slubbing, yarn or fabrics. The material to be dyed can also be in the form of mixed fibers which can cousst, for example, of poly-amide fibers and incrusted cellulose fibers, or in the form of blended fabrics, particularly from wool and polyester fibers such as cellulose acetate, cellulose triacetate and, particularly, polyterephthalic acid glycol ester fibers. In these mixtures, only the polyamide (e.g., the wool) or also the polyamide and polyester components can be dyed simultaneously with dyestuffs suitable therefor.

The fibers are impregnated, for example, by printing, in which case wool can be previously chlorinated, as is conventionally the case prior to printing thereon, or the fibers can be impregnated by coating or spraying, preferably, however, by padding. The impregnating solution (pad liquor) according to the invention is advantageously prepared by mixing warm aqueous dycstuff solutions or dispersions of suitable concentration, which contain thickeners, with the desired amount of carrier mixture according to the invention, as defined herebefore, as well as, optionally, other additives. The polyamide fibers are impregnated advantageously at 30 to 70 C. and then equeezed out to the desired content of impregnating liquor which is about 40 to 130%, and preferably 50 to 100%, of the weight of the fiber (400 grams to 1,300 grams per kilogram of goods).

The impregnated fibers are then steamed by the usual methods, advantageously with neutral saturated steam.

Subsequently to the aforesaid steaming, the dyestufi" is preferably fixed on the fibers by treatment in a hot acid bath by known methods (acid shock). The acid content is advantageously about 9 to 10 grams per liter. Preferably, the goods are introduced into the acid bath at to 98 C. To adjust the acid pH value of the bath, inorganic and organic acids are suitable, e.g., sulfuric, phosphoric or hydrochloric acid or formic or acetic acid. Organic acids are preferred, in particular formic acid. In some cases it is useful to add water-soluble salts, preferably water-soluble calcium salts to the acid bath. Development can also be performed by continued steaming as well as, in the case of polyamide and polyacrylonitrile fibers, with hot dilute acid.

The fixed goods are then advantageously rinsed, e.g., with cold or warm water which can contain the auxiliaries usual in the dyeing industry, e.g., formic acid or acetic acid or also wetting or detergent substances.

Pad liquors suitable for carrying out the padding process according to the invention can also be prepared from pre-mixed pastes which contain as the essential ingredients:

(a) 8 to 35%, and preferably 10 to 20% by weight of a suitable dyestulf as defined hereinbefore,

(b) 5 to 25% by weight of a dyestuff carrier mixture according to this invention, the aforesaid percentages being calculated on the total weight of the paste, the balance consisting of (c) water, and, furthermore, optionally,

(cl) depending on the nature of the dyestuff, acid or alkaline agents such as, in particular, acetic acid, formic cid, sulfuric acid, phosphoric acid, sodium or potassium carbonate or bicarbonate, sodium or potassium acetate, or sodium or potassium hydroxide, in amounts sufficient to adjust the pH of the paste to a value most compatible with the dyestuif and with the maintenance of a satisfactory homogeneity of the paste, and, optionally of,

(e) Thickener in sufiicient amount to impart to the paste a viscosity in the range of from 1 to 50, and preferably 10 to 40, poises.

A homogeneity-enchancing and/ or preserving agent such as isopropanol or one of the other compounds mentioned hereinbefore of the here-employed carriers according to the invention, is especially present in the paste in those cases where the latter is prepared from carriers listed above which contain such ingredient.

Pad liquors for use in the method according to the invention are prepared from these pastes by diluting the latter with water, preferably in such proportions that 1 kg. of pad liquor is obtained from every 100 to 400 kg. of paste, depending on the desired depth of shade of the resulting dyeings.

The use of such pastes in the preparation of pad liquors represents a considerable advantage over the conventional preparation from the individual constituents, and, usually, the dyestuffs are present in the pad liquors thus prepared from pastes according to the invention, in a fine and particularly uniform distribution, especially independent of the amount of pad liquor being prepared, which is not easily achieved and not as easily reproducible by preparation of the pad liquors by other methods.

The process according to the invention for the dyeing of organic fibers has remarkable advantages over similar known processes. The main advantage consists in the pH range which stretches very far and deep into the acid region at which dyeing can be performed, so that the most favorable dyeing conditions can be chosen without the pH of the liquor being taken into consideration. Thus, for example, because of the possibility of dyeing in the acid range also, certain chromable dyestuffs such as Eriochrome Black T can be used with chromium (III) salts.

This has not been possible previously. Another advantage of the process according to the invention is that the pad liquors are homogeneous under the conditions of the above-described dyeing method and remain so for a long time, as mentioned hereinbefore.

While known pad liquors, especially those consisting of two phase emulsions, which form a so-called coacervate suffer easily phase separation within a relatively short time, require special adjuvants such as alginates to postpone this separation, and, once such separation has occurred, yield spotty, unlevel dyeings, the pad liquors according to the invention need no such stabilizing adjuvants and remain stable since they are one-phase systems They thus do not require such careful adjustment of the proportions of the ingredients, are simpler to prepare, and do not require special stabilizing adjuvants but can be used with satisfactory results, after standing for weeks or even months.

Dyeings obtained with the pad liquors according to the invention show good dyestuff yields and particularly good fixability of the dyestutf on the fibers after padding, without any special further adjuvants. In particular, dyed fibers and filaments padded according to the process of the invention are, to our knowledge, the first that permit: successful fixation of the fiber by steaming directly following padding. When steaming, for instance, fibers or slubbing, these goods are given a fluffy texture blowing up the space occupied by the padded goods by just the right amount, namely about three to seven times the original volume, but not further so that no entanglement of the fibers occurs which might disturb passage of the material through the steaming apparatus, whereby a rapidly fixable material is obtained. The desirable blow-up of the texture practically never occurs if the mixed carriers according to the invention in the pad liquors used in the above-described process are replaced by the individual components of these mixed carriers, c.g., the sulfutcd polyglycol ether alone, or the fatty acid amide component alone. Known mixed carriers, on the other hand, lead to excessive blow-up, entanglement of the fibers in the material and the above-mentioned disturbances in the steaming operation.

Use of either component alone, in lieu of the highly critical mixtures of the two components as defined above also leads to other draw-backs, such as dependence on, for instance, wool of specific origin, while wool blends from different origin can be dyed evenly in the same bath with the pad liquors used in this invention. Another drawback of pad liquors containing as carriers only one of the two components of the mixed carrier employed according to the invention, is the formation, during fixation by steaming, of the socalled sandwich etfect mentioned hereinbefore, which imparts a greyish hue to the finished dyeings.

As a further advantage, dyeing with pad liquors hereemployed permits much shorter steaming times, for instance, depending on the nature and concentration of the dyestuffs, only 20 minutes, where, with the same dyestuff in the same concentration, use of a known carrier would require 40 minutes of steaming.

Carrier as used in this specification and the appended claims means a color transfer agent which assists in carrying the dyestulf from a pad liquor or ink on to and into the fiber to be printed.

The following non-limitative examples serve to illustrate the invention further. The temperatures given therein are in degrees centigrade. Where not otherwise stated, parts and percentages are given by weight. The relationship of parts by weight to parts by volume is as that of grams (g.) to milliliters (1111.) CL means Color Index, Second Edition, 1956, published by The Society of Dyers and Colourists, Bradford, England, and The American Association of Textile Chemists and Colorists, Lowell, Mass, U.S.A.

EXAMPLE 1 40 parts of the commercial form of the chromium complex compound of the monoazo dyestuff Z-aminophenol 4-methylsulfonee1-phenyl-3-methyl-pyrazolone (molar ratio of dyestuff: chromium is 2:1)containing about 50% of sodium sulfate as diluting agentare dissolved in a 60-warm mixture of 300 parts of an aqueous 2.5%-solution of carob bean flour and 30 parts of a carrier mixture consisting of the sodium salt of sulfated lauryl alcohol diglycol ether coconut oil fatty acid, N,N-bis-(B-hydroxyethyD-amide and isopropanol in a weight ratio of 9:9:2, and 250 parts of water. The resulting solution is diluted to 900 parts with warm water (60 C.) and the pH is adjusted to about 2.5 with formic acid. The temperature of the mixture should then be about 50. This solution is then diluted with water to 1000 parts. Wool flannel is impregnated at 50 With this liquor, squeezed out to a liquor content of about 100% calculated on the dry weight of the fibers and steamed with saturated steam for 15 minutes at 98. The goods are then washed first with a solution containing 1 gram (g.) per liter of nonylphenolpolyglycol ether condensation product (molar ratio about 1:12), then rinsed with water and then washed with an aqueous solution containing 2 milliliters (ml.), per liter, of formic acid and again rinsed with water.

A level, well penetrated orange wool dyeing is obtained which has no so-called sandwich efiect.

By using in the above example, instead of the dyestuff mentioned, similar chromium-containing monoazo dyestuffs of the type containing 2 dyestuff molecules per chromium atom (2:1 complexes) which contain no sulfonic acid groups but which are substituted by lower alkylsulfonyl groups or which contain sulfonic acid amide groups which may be substituted at the nitrogen atom by alkyl groups, for example, the chromium-containing dyestutf: 2-aminophenol-S-sulfonic acid an1ide l-phenyl-3- methyl-pyrazolone, the chromium-containing dyestuff mixture: 2-amino-5-nitrophenol Z-hydroxynaphthalene, 2 amino 5 nitrophenol l hydroxynaphthalene 3,6- bis-sulfonic acid methylamide (dyestuff:chromium=2:1) or the chromium-containing monoazo dyestuff: 2-aminophenol 4 methylsulfone l acetylamino 7 hydroxynaphthalene (dyestutf:chromium=2:l), while otherwise the procedure given in the above example is followed, equally well penetrated and level red, navy blue or grey colored wool flannel dyeings, respectively, are obtained.

By using, instead of the carrier mixture given in the above Example 1, parts of a carrier mixture prepared by mixing with each other: 9 parts of the ammonium salt of sulfated lauryl alcohol triglycol ether 9 parts of coconut oil fatty acid-N,N-bis-(hydroxyethyl)- amide, and 2 parts of isopropanol and following the procedure given in the example, paragraph one, equally well penetrated and level dyeings are obtained.

Also diand tri-ethanolamine salts of sulfated lauryltriglycol ether can be used instead of the ammonium salt.

EXAMPLE 2 Woolen slubbing is padded with the liquor described in the first part of Example 1, the pH of which, however, has been adjusted to 4 with acetic acid instead of formic acid, and the procedure given in the first part of Example 1 is followed.

Equally well penetrated and level orange, red, navy blue or grey dyed woolen slubbing is obtained.

Turquoise dyeings of similarly good qualities are obtained by repeating Example 2, but using, instead of the 40 parts of dyestufi used therein, 20 parts of the corn mercially available dyestufi Solophenyl Turquoise Blue GL (C1. Direct Blue 86), and otherwise following the same method as given in Example 2.

Similar satisfactory results are obtained when carrying out the procedure given in the first paragraph of Example 1 with a carrier mixture free from isopropanol.

EXAMPLE 3 By repeating the above Example 2, but using, instead of the last-mentioned dyestuffs, 20 g. of the copper complex of the dyestufl of the formula COOH produced as described in Example 2 of the US. Patent 2,839,521 to Schetty, issued June 17, 1958, wool slubbings of very fast, light brown shades are obtained.

EXAMPLE 4 By repeating the above Example 2, but using, instead of the last-mentioned dyestufl 18 g. of the commercial dyestuff Reacton Brilliant Red BGL (Color Index, 2nd Edition, Reactive Red 20) wool slubbings of particularly brilliant red shades are obtained.

EXAMPLE 5 W001 flannel is impregnated at 60 with pad liquor prepared as described in the first part of Example 1 and squeezed out to a liquor content of about 100%. The padded fabric is introduced into a 98-warm aqueous bath which contains 8 cc./liter of 85% formic acid, and is left in this bath for 5 minutes. The wool flannel so dyed is then washed with a 45-warm aqueous solution of 0.5 g./ liter of nonylphenol polyglycol ether for 5 minutes, whereupon it is rinsed with cold water. The resulting orange dyeing is well penetrated and has no sandwich effect.
