Description

BACKGROUND OF THE INVENTION The present invention relates to an active substance of textile auxiliaries for finishing dyes and anionic dye prints.

Finishing dyes and prints is a difficult operation / especially for reactive dyes. The resulting color fastnesses are mainly dependent on perfect removal of the non-fixed and hydrolyzed dye.

The classic procedure for finishing reactive dyes and prints involves first removing the alkali by washing in cold water, then intensive washing with bath exchange at 50-80 ° C, soaping with an anionic surfactant at boiling point, washing with warm water and a final rinse with cold water. The whole process is characterized by high demands on the amount of process water and time.

Therefore, possibilities have been sought to shorten the finishing operations _from both the optimization of the properties of the reactive dyes and the dyeing or printing process.

One possibility of intensifying the scrubbing process is the use of the compounds of A.O. 245 170. From cationic compounds, reaction products, products of 1,3-bis (3-chloro-2-hydroxypropyl) or 1,3-bis (2,3-epoxypropyl) imidazolinium salt and multifunctional aliphatic amines. These substances significantly reduce the washing time of reactive dyes and improve the fastness of dyeing and prints;

Of the other anionic dyes, the finishing process for sulfur dyes is also very important for dyeing. Oxidation with active oxygen releasing agents provides a cleaner shade, but laundancy is on average 1 to 2 degrees lower than when finished with potassium dichromate. Due to the high toxicity of chromium salts and the burden of wastewater, it is prohibited to discharge chromium-containing wastewater in a number of areas.

The compounds of A.O, 245,170 have found application in this field as well. 250,569 allows to obtain dyeings with stability at least at the level of potassium dichromate completion.

Further research in the field of imidazolinium compounds has shown the possibility of utilizing new anionic dye types for finishing dyeing and printing, which have a higher effect on those compounds of A.O. They therefore more easily penetrate into the fibrous substrate and thus further accelerate the washing process.

The reaction proceeds under normal pressure at temperatures of 20 to 150 ° C. preferably at 50 to 90 ° C,

Depending on the amide nitrogen substituents, the starting compounds of formula 4 give rise to less or more complicated compounds. The resulting constitution also depends on the molar ratio of the two reacting components. Some of the basic options are shown in Tables 1 and 2,

The preparation of the compounds of the invention and their use is illustrated in the examples.

The preparations are of particular importance for reactive and clear dyes on cellulosic materials, but their use is not excluded for other groups of dyes and other textile fiber substrates.

Example 1

261 907

Dilute 162 kg of N- (2-aminoethyl) oleylamide in 100 L of water in a 500 L duplicator and add 175 kg of a 83% aqueous solution of 1,3-bie (3-chloro-2-hydroxypropyl) imidazolinium sulfate at 60 ° C over 60 minutes. The reaction mixture was allowed to react for a further 60 minutes at 80 DEG C. with stirring, and the resulting brown pasty substance contained 71.4% of Compound No. 1 of Table 1.

Example 2

In a duplicator of Example 1, 169 kg of N- (2-aminoethyl) ricinoylamide are stirred in 100 l of water at 70 ° C. 176 kg of a 81% aqueous solution of 1,3-bis (3-chloro-2-hydroxypropyl) imidazolinium chloride are gradually added over a period of 60 minutes. The mixture was allowed to react at 70 ° C for a further 90 minutes. The paste resulting from the reaction contained 70% of Compound No. 2 of Table 1.

Example 3

Cotton yarn 2x29.5 tex ee on dyeing apparatus dye the usual technology with dye reactive blue numbers C.I. 109 at 4.5% saturation. After washing with cold water for 7 minutes and washing with water at 70 ° C for the same time, the yarn is treated for 10 minutes at 95 ° C in a bath containing η

1.5 g.l * of compound number 1 of Table 1, calculated on the pure active substance. After washing with 60 ° C water for 5 minutes and rinsing with cold water, the dyeing is complete. The color fastness in water is 4-5 / 4-5 / 4-5, which is 1 degree better in embedding conditions than in the conventional finishing process.

Example 4 _f

The cotton knit ee on a hydrodynamic machine will color the sulfur blue number C.I. 10 at 5% saturation. After staining, the fabric is washed for 10 minutes in cold water.

This is followed by finishing in a bath containing 2 g / l of compound number 2 of Table 1, calculated on the pure active substance. Bath ratio 10-10, temperature 50 ° C, treatment time 15 minutes. This is followed by a 40 ° C water wash for 15 minutes and a final cold water wash for 10 minutes. The resulting 9-color dyes in washing at 60 ° C are 4-5 / 5/5.
