The present invention also relates to a process for preparing the quaternized condensation products and to the use thereof as aftertreating agents for fixing dyeings and prints on textile materials which contain cellulose fibers and have been dyed or printed with reactive or direct dyes, and to a process for this aftertreatment.

Textile materials which contain cellulose fibers and have been dyed or printed with reactive or direct dyes are usually subjected to an alkali wash in the presence of surfactants in order to remove the unfixed dye portions. This procedure gives dyed or printed cellulose materials which, it is true, have adequate wash fastness properties but are in need of improvement in respect of the waterfastness, the hot-press fastness and the perspiration fastness.

The aftertreating process described in DE-A-3,526,101 using cationic condensation products obtainable by reaction of piperazine derivatives with bifunctional halogen or epoxy compounds and subsequent quaternization with benzyl chloride leads to substantial elimination of the defects described, but in some cases impairs the crock fastness and in particular the lightfastness.

EP-B-087,147 relates to reaction products of triethanolamine condensates and xylylene dichlorides. However, these products are not used in the textile industry, but are used as emulsion breakers, lubricants and paper assistants.

EP-A-223,064 deals with benzyl chloride-quaternized condensation products of triethanolamine and/or triisopropanolamine as aftertreating agents for the fixation of reactive dyeings. These compounds bring about an improvement not only in the wet but also in the crock and lightfastness properties. To obtain the desired application properties, however, trialkanolamine condensates of a high degree of condensation which corresponds to a viscosity of not less than 40,000 mPa.s in the undiluted state in the case of triethanolamine and of not less than 600,000 mPa.s in the undiluted state in the case of triisopropanolamine are required. The preparation of such high-viscosity polyaminoethers is, as explained in EP-B-087,147 highly problematical at just below the gel point because of the difficult-to-control condensation reaction, since the reaction mixture tends to form a solid, insoluble mass here which is no longer handlable for any further reaction.

It is an object of the present invention to provide conveniently preparable aftertreating agents for the purpose mentioned which ensure high wetfastness properties without impairing the crock and lightfastness properties.

We have found that this object is achieved by the quaternized condensation products defined at the beginning.

The precondensates used for preparing the cationic resins according to the invention can be obtained by heating the trialkanolamines I, in particular triethanolamine or triisopropanolamine N[CH.sub.2 --CH(CH.sub.3)--OH].sub.3, in the presence of acid catalysts, preferably phosphorous or hypophosphorous acid, at from 120.degree. to 280.degree. C. as described in EP-A-223,064. In a departure from the process of this EP-A, however, the reaction of the process according to the invention is advantageously discontinued by cooling at distinctly below the gel point once a viscosity range from 5,000 to 35,000 mPa.s, preferably from 10,000 to 25,000 mPa.s, for triethanolamine or from 100,000 to 600,000 mPa.s, preferably from 200,000 to 500,000 mPa.s, for triisopropanolamine or from 100,000 to 250,000 mPa.s for a cocondensate of preferably equimolar amounts of triethanolamine and triisopropanolamine has been reached (in each case the viscosity is measured in the undiluted state at 20.degree. C.). To effect further crosslinking and/or to incorporate groups of different polarities at the chains which carry the alcohol functions and/or to quaternize the central nitrogen atoms, the precondensates obtained are reacted with one or more compounds IIa-IIe.

C., without solvent to a viscosity of from 20,000 to 300,000 mPa.s, preferably from 28,000 to 150,000 mPa.s, and with an epihalohydrin IIc without a solvent at from 40.degree. to 150.degree. C., preferably from 60.degree. to 130.degree. C., or in an aqueous or even aqueous-alcoholic solution not less than 40% strength by volume at from 40.degree. to 100.degree.

The precondensate formed from triisopropanolamine is preferably reacted with a urea IIb (n=0, r=1), a bisurea IIb (m=n-r-1) or a cyclic carbonate IIa (R.sup.4 -R.sup.5 =O-alkylene-O, n=0) at from 100.degree. to 210.degree. C., preferably from 140.degree. to 200.degree. C., without solvent to a viscosity of more than 500,000 mPa.s and with an epihalohydrin IIc without solvent at from 40.degree. to 150.degree. C., preferably from 60.degree. to 130.degree. C., or in an aqueous or even aqueous-alcoholic solution not less than 40% strength by volume at from 40.degree. to 100.degree. C.

The precondensate formed from a mixture of triethanolamine and triisopropanolamine, preferably in a molar ratio of 1:1, is reacted for example with a urea IIb (n=0, r=1), a bisurea IIb ( m=n=r=1) or a cyclic carbonate IIa (R.sup.4 -R.sup.5 =O-alkylene-O, n=0) at from 100.degree. to 210.degree. C., preferably from 140.degree. to 200.degree. C., without solvent to a viscosity of more than 300,000 mPa.s.

The reaction products of the polyaminoether precondensates and compounds IIa-IIe are then reacted with from 25 to 100 mol %, preferably from 60 to 95 mol %, of one or more of the benzyl halides III of the type defined.

Preference is given to benzyl chlorides which are monosubstituted in the para position (X=Cl, p=1), but particular preference is given to unsubstituted benzyl chloride (X=Cl, p=0).

The benzyl halide reacts chiefly with the central nitrogen atom of the polyaminoether/compound IIa-IIe condensation product, thereby quaternizing said condensation product.

The reaction with the benzyl halide is preferably carried out in aqueous or even aqueous-alcoholic medium at from 60.degree. to 100.degree. C., but can also be carried out at higher temperatures using shorter reaction times, although in this case it will have been necessary to employ superatmospheric pressure. The aqueous or aqueous-alcoholic solution of the quaternized product can be used directly, with or without an addition of diethylene glycol, in the textile sector as provided for by the invention.

The condensation product according to the invention can be used as an aftertreating agent for fixing dyeings and prints on textile materials which contain cellulose fibers and have been dyed or printed with direct or preferably reactive dyes.

The textile materials which contain cellulose fibers can be present in the form of fibers, yarns, fabrics or other piece goods. The cellulose fibers are preferably cotton, linen or staple viscose. The textile materials which can be aftertreated according to the invention can consist of cellulose fibers alone or contain cellulose fibers blended with synthetic fibers such as polyamide, polyacrylonitrile or polyester fibers.

The textile material is dyed or printed with commercial reactive or direct dyes in a conventional manner. For instance, reactive dyes are applied at from 20.degree. to 100.degree. C. by the exhaust method or at room temperature by the cold pad-batch method; after dyeing, the textile material is thoroughly rinsed with water, advantageously first at least once with cold water and then at least once with water at from 70.degree. to 100.degree. C.

The aftertreatment of the dyed or printed cellulose fiber materials wherein the cellulose fibers may be present blended with other types of fibers is preferably effected batchwise or continuously with an aqueous liquor of the quaternized condensation product using a customary technique for applying aftertreating agents. The batchwise aftertreatment of the dyed or printed materials with the aqueous liquor takes in general from 5 to 30 minutes. The concentration of the water-soluble quaternized resin in the aftertreating liquor is preferably from 0.1 to 5.0 g/l, particularly preferably from 0.25 to 2.0 g/l. The liquor ratio (ratio of aqueous liquor in 1 to dry textile material in kg) is within the range from 5:1 to 50:1, preferably from 10:1 to 20:1. The aftertreating liquor preferably has a pH within the range from 4 to 11, particularly preferably from 5 to 8. However, the quaternized resin can also be applied to the textile material which is to be aftertreated by padding. Padding is generally effected with an aqueous solution of quaternized resin in a concentration of from 1.0 to 50 g/l, preferably from 2.5 to 15 g/l.

The aftertreatment according to the invention is customarily carried out within the temperature range from 5.degree. to 100.degree. C., preferably at from 40 to 70.degree. C., by a method similar to the exhaust method. Alternatively, the dyed or printed textile material is first rinsed with cold and hot water, then treated with the aqueous solution of the quaternized resin, almost to boiling point within the range from 70.degree. to 100.degree. C., and subsequently rinsed with water. After the aftertreatment according to the invention the textile material which contains cellulose fibers can be rinsed. It is then dried.

The aftertreating process with the quaternized condensation product prepared according to the invention leads to the dyeings and prints obtained having high wetfastness properties. Excellent results are obtained in particular in the severe waterfastness test, for the perspiration fastness and for the hot/moist test. The light fastness properties are not impaired compared with a dyeing which has not been aftertreated according to the invention, in contradistinction from conventional aftertreating agents which frequently cause the lightfastness properties to deteriorate. Nor are the crock fastness properties impaired by the aftertreating process according to the invention; in some cases they are even somewhat improved.

Further advantages of the aftertreating process according to the invention are the nonappearance of precipitates which frequently result when assistants come together with hydrolyzed reactive dye portions washed out of the textile material, and the nonbrightening of dyeings or prints, so that there are no shade changes even in the case of combination shade dyeings.

EXAMPLES

The percentages used in the Synthesis and Use Examples are by weight, unless otherwise stated. The viscosities were measured at 20.degree. C. in a rotary viscometer (Haake, Rotavisco).

SYNTHESIS EXAMPLES

Synthesis Example 1

1788 g of triethanolamine and 12 g of hypophosphorous acid (50% strength aqueous solution) were heated with stirring to 225.degree.-230.degree. C. while a slow stream of nitrogen was passed through the mixture. The water formed in the course of the reaction was distilled off. After 7-8 hours, the condensation was discontinued at a viscosity of 21,000 mPa.s by cooling to room temperature, affording 1492 g of triethanolamine condensate (amine number: 7.69 mmol/g).

130 g of this triethanolamine polyether were heated together with 3.0 g of urea (corresponding to 5 mol %) with stirring to 170.degree.-180.degree. C. under nitrogen, and the mixture was maintained at that temperature for 6 hours until the evolution of ammonia had ceased. The urethane thus obtained (viscosity 41,000-45,000 mPa.s) was diluted with 100 g of water and heated to 70.degree. C. 101 g of benzyl chloride (corresponding to 80 mol %) were then added dropwise in the course of 2 hours. The mixture was then stirred at 80.degree. C. for 3 hours and adjusted with 133 g of water to a 50% level in respect of cationic compound.

1530 g of triisopropanolamine and 8.0 g of hypophosphorous acid (50% strength aqueous solution) were heated with stirring to 200.degree.-225.degree. C. as described in Synthesis Examples 1 and 10 while a slow stream of nitrogen was passed through the mixture. The water formed in the course of the reaction was distilled off. The condensation was discontinued at a viscosity of 390,000 mPa.s by cooling to room temperature.

359.6 g of this triisopropanolamine precondensate (amine number: 5.56 mmol/g) were heated with 6.0 g of urea (corresponding to 5 mol %) with stirring to 170.degree.-180.degree. C. under nitrogen and maintained at that temperature for 5 hours until the evolution of ammonia had ceased. On cooling to room temperature, the reaction product became solid. It was dissolved in a mixture of 210 g of water and 85 g of isobutanol at 70.degree. C. and admixed at that temperature with 208 g of benzyl chloride (corresponding to 82 mol %) in the course of 2 hours. It was then refluxed for 13 hours. The isobutanol was then distilled off, and a sufficient amount of water was added by weight to replace the distillate. 270 g of diethylene glycol were added to prepare a clear solution.

Synthesis Example 12

A mixture of 128.4 g of a triethanolamine precondensate (amine number: 7.79 mmol/g) of viscosity 15,000 mPa.s, prepared as in Synthesis Example 1, and 32 g of water (viscosity of the resulting mixture 2800 mPa.s) was admixed with 5.6 g of epichlorohydrin (corresponding to 6 mol %) added dropwise. The solution was heated to 70.degree. C. The pH was maintained at 9 by the addition of a total of 5.0 g of concentrated hydrochloric acid. The viscosity of the solution rose from 15,000 to 16,000 mPa.s in the course of 8 hours. After addition of 76.8 g of water, 76 g of benzyl chloride (corresponding to 60 mol %) were added dropwise at 70.degree. C. The mixture was stirred at 80.degree. C. for 3 hours and diluted with 100 g of water.

The method of Synthesis Example 12 was also used to prepare the quaternized compounds listed in Table 2.

Synthesis Example 17

129.5 g of a triethanolamine precondensate (amine number: 7.72 mmol/g) of viscosity 23,500 mPa.s, prepared as in Synthesis Example 1, and 4.6 g of epichlorohydrin (corresponding to 5 mol %) were heated to 100.degree.-105.degree. C. and stirred at that temperature for 5 hours. The viscosity of the melt after it had cooled down to 20.degree. C. was 65,400 mPa.s. After 80 g of water had been added, the mixture was reacted at from 70.degree. to 80.degree. C. with 85.3 g of benzyl chloride (corresponding to 67 mol %).

Synthesis Example 18

129.5 g of a triethanolamine precondensate (amine number: 7.72 mmol/g) of viscosity 23,600 mPa.s, prepared as in Synthesis Example 1, and 5.1 g of 1,3-propylene carbonate (corresponding to 5 mol %) were stirred at 150.degree. C. for 2.5 hours and then at 180.degree. C. for 2.5 hours while a slow stream of nitrogen was passed through the mixture. The viscosity was then 28,300-29,500 mPa.s. After the addition of 80 g of water, 91 g of benzyl chloride (corresponding to 72 mol %) were slowly added dropwise at 70.degree. C. The mixture was then stirred at 80.degree. C. for 3 hours.

The preparation of a quaternized condensation product with ethylene carbonate can take place in the same way as the reaction with 1,3-propylene carbonate.

USE EXAMPLES

The suitability of the quaternized condensation products according to the invention as aftertreating agents was tested on bleached, mercerized and reactive-dyed cotton cloth.

General dyeing method I (for reactive dyes of medium reactivity): the cotton material was introduced at 25.degree. C. and a liquor ratio of 10:1 into a dyebath containing the dyes mentioned in the Use Examples in commercial form, 60 g/l of sodium sulfate, 2.0 ml/l of 38.degree. Be sodium hydroxide solution and 5.0 g/l of sodium carbonate and 1.0 g/l of sodium m-nitrobenzenesulfonate to prevent undesirable reduction of the dye. Following a dwell period of 15 minutes at 25.degree. C., the bath was heated to 80.degree. C. in the course of 30 minutes and kept at that temperature for 60 minutes. After dyeing, the material was rinsed with cold water in a liquor ratio of 20:1 for 10 minutes, the rinse liquor was dropped, and the material was then treated with water at 98.degree. C. for 10 minutes.

General dyeing method II (for reactive dyes of high reactivity): the cotton material was introduced at 15.degree.-17.degree. C. and a liquor ratio of 10:1 into a dyebath containing the dyes mentioned in the Use Examples in commercial form, 60 g/l of sodium sulfate and 15 g/l of sodium carbonate. Following a dwell period of 10 minutes, the bath was heated to 30.degree. C. in the course of 15 minutes and kept at that temperature for 60 minutes. After dyeing, the cloth was rinsed cold and hot as in general dyeing method I.

The following tests were used to assess the fastness properties of the dyeings:

lightfastness following Xenotest irradiation (DIN 54 004) alkaline and acid perspiration fastness (DIN 54 020) dry and wet crock fastness (DIN 54 021) severe waterfastness test (DIN 54 006) hot/moist test (storage in saturated steam at 80.degree. C. for 72 hours).

In the hot/moist or hot-press test, the dyed material, after it has been stored in saturated steam, is placed between two white cotton fabrics; this sandwich is thoroughly wetted with water and then hot-pressed twice at 180.degree. C. in a hot-press machine for 30 seconds each time and dried in the machine. As a result of this treatment, the unfixed dyes or the dyes which have been hydrolyzed by the thermal treatment migrate from the dyed to the white material. The hot/moist test simulates six months, storage of the reactive dyeings at room temperature. This test method is very sensitive and tougher than the severe waterfastness test of DIN 54 006. The assessment ranges from 0 to 10, a rating of 10 being best.

Use Example 1

Bleached and mercerized cotton cloth was dyed with 0.8% of the dye C.I. Reactive Blue 41 by method I. It was then treated for 15 minutes at 50.degree. C. with an aqueous solution containing, based on the dry textile material, 1.0% of the quaternized resin of Synthesis Example 2. The pH of the liquor was 7.6. The result obtained was a dyeing whose lightfastness was not impaired compared with a dyeing which had been soaped off in a conventional manner, ie. without aftertreating agent. The hot/moist test rating was 10.

Use Example 2

A dyeing was prepared with 10% of the dye C.I. Reactive Blue 41 and then aftertreated, both steps being carried out as described in Use Example 1.

Use Example 3

Two cotton dyeings by method I with 0.25% and 1.6% of the dye C.I. Reactive Brown 32 were aftertreated as described in Use Example 1. For comparison, two dyeings were also aftertreated with a commercial polycationic fixing agent. The lightfastness of the lighter dyeing was 4, that of the darker dyeing 5; the comparative dyeings were each lower by 1.5. The hot/moist test rating was 10 in each case; the ratings for the comparative dyeings were 10 for the lighter dyeing and 8 for the darker dyeing.

Use Example 4

The bleached and mercerized cotton material was dyed with 2.1% of the dye C.I. Reactive Red 204 by method I. It was then aftertreated for 15 minutes at 40.degree. C. with an aqueous solution which, based on the dry textile material, contained 1.0% of the resin of Synthesis Example 14. The pH of the aftertreating liquor was 7.7. The aftertreated dyeing gave a severe waterfastness test rating of 5 and a hot/moist test rating of 9-10. A comparative dyeing which had not been aftertreated had a severe waterfastness test rating of 3-4 and a hot/moist test rating of 4-5.
