Description

The invention relates to an active ingredient in textile auxiliaries for fixing dyeing with anionic dyes.

To increase the fastness of anionic dyes on cellulose materials, cationic preparations are used, which form sparingly soluble salts with dye anions. The fixing effect depends on the molecular weight of the dye and the number of sulfo groups in the dye.

The most well-known are cationic condensation products of dicyandiamide and formaldehyde, melamine and formaldehyde, urea and formaldehyde, as well as pyridinium compounds and quaternary ammonium compounds with a fatty chain. The above-mentioned compounds generally negatively affect the light fastness of both substantive and reactive dyes. In the conditions of our textile industry, a fixing agent based on the condensation product of formaldehyde and dicyandiamide is used. Due to capacity and raw material problems, there is a permanent shortage of this agent.

In recent years, intensive research has been conducted in the field of using heterocyclic compounds with two nitrogen atoms for the preparation of textile auxiliaries. AO 221 458 describes the effect of the reaction products of these heterocyclic compounds and epichlorohydrin on improving the sinterability of cellulose fibers. However, these substances are capable of reacting not only with cellulose, but can be the starting product for the preparation of a whole range of textile auxiliaries.

One of the possibilities according to AO 245 170 is the use of reaction products of the general formula

where n is an integer from 2 to 10 and s is an integer from 1 to 4

These compounds are particularly suitable for finishing and fixing dyeing with reactive and sulphur dyes. Their effect on substantive dyes is not as pronounced.

According to the invention, fixing preparations with very good efficiency for reactive and sulfur dyes, but also for substantive dyes, can be derived from the above-mentioned imidazolinium compounds. These are preparations containing an active substance based on structural units of the general formulas ,0

The reaction takes place at temperatures of 20 to 150 ^° C, preferably in the temperature range of 50 to 70 °C. Some of the compounds according to the invention are listed in Table 1. These substances can be applied as fixing agents from water baths on conventional finishing equipment at the end of the dyeing process, after thorough removal of the dye adhering to the surface. Both discontinuous and continuous processes can be used.

The procedure for preparing and using the compounds of the invention is illustrated in the following examples:

Example 1

In a 500 l duplicator, 60 kg of N-(2-aminoethyl)hexadecanamide are mixed in 300 l of water at a temperature of 70 °C. Over the course of 30 minutes, 70 kg of an 83% aqueous solution of 1,3-bis(3-chloro-2-hydroxypropyl)imidazolium sulfate are gradually added. The temperature is maintained at 70 °C for another 90 minutes. The finished product is poured into prepared containers without cooling. After cooling, it acquires a pasty consistency. The paste contains 27.4% of the compound, the constitution of which corresponds to formula number 3 in Table 1.

Example 2

In the duplicator according to Example 1, 130 kg of N-(2-aminoethyl)octadecanamide are mixed in 250 l of water at a temperature of 70 °C. 68 kg of an 80% aqueous solution of 1,3-bis(3-chloro-2-hydroxypropyl)imidazolinium chloride are added over a period of 30 minutes. The procedure is completed according to Example 1. The paste contains 41.6% of compound number 6 from Table 1.

Example 3

Mercerized cotton fabric is dyed on a ber260769 visím jigr in the usual way with the dye Direct Blue number CI 78 in a saturation of 2 %/o. After thorough washing with cold water, the fabric is treated with a bath containing 2 g. 1 ^_1 of compound number 4 from table 1, calculated on the active substance. Processing temperature 40 °C, bath ratio 1 : 3, processing time 40 minutes. The action of the compound according to the invention increases the fastness of the dye in water by 2 degrees, fastness in sweat by 1.5 degrees and fastness in washing at 40 °C by 1 degree, evaluated by sinking into the accompanying fabric.

Example 4

A braid made of a mixture of cotton and viscose staple is dyed on a reel using the usual dyeing procedure with Reactive Red CI 2 to a saturation of 4%. After the usual washing and soaping, the dyeing is fixed with a bath containing 1 g. 1 ^_1 of the compound pure 6 of Table 1, calculated as the active substance, at a temperature of 30 °C for 15 minutes and a bath ratio of 1 : 25. The fastness of the dyeing in water increases by 1 degree at a value of Table 1

Example 5

A fabric made of a mixture of polyester and cotton fibers in the ratio of 65:35% is dyed with a disperse dye by passing through a thermo-insulating device, thereby covering the polyester portion. On a continuous dyeing machine with a feather, the cellulose portion is dyed with the dye Sulfur black No. 10 CI 1, 50 g . I ^-1 . After passing through a steamer and an air passage, the fabric is washed by passing through 4 tubs of a wide-area washing machine with cold water. In two other tubs, a bath containing 1 g. I ^-1 of compound number 2 from Table 1 is fixed at 40 °C. In the remaining 3 tubs of the wide-area washing machine, the fabric is neutralized with acetic acid and washed.

The dyeing has high wash fastness at 60°C, compared to non-permanent dyeing, the fastness is improved by 1 degree.
