The dyeing of oellulose fiber materials and the use of reactive quaternary ammonium salts has recently come to the forefront of interests motivated by efforts to rationalize the technology of the ferocious as much as possible.

The effect of these preparations is approximately the same. The cellulosic materials treated with these substances prior to dyeing are increasingly absorbing anionic dyes and significantly increasing the color fastness thereto. Some lower molecular weight formulations allow single-application with the dye. The compounds of formulas 2, 3 and 4 in an alkaline medium react with an epoxy group or a chlorohydrin group with hydroxy groups to form a covalent bond. The quaternary amine group then ionically binds anionic dyes.

However, the known compounds of formulas 2, 3 and 4 do not always meet all the criteria in terms of usability and ecology of hygiene properties.

The formulations of the present invention differ from the known compounds of formula 4 in a substantially altered reactive group which, with unchanged efficacy, offers advantages in simplifying manufacture and, in particular, in reducing toxicity.

The compounds of formula (1) can be, like all so-called. Apply cationic preparations before dyeing, simultaneously with dyeing and for dyeing. First of all, the first two ways are of practical importance.

Prior to dyeing, the textile materials are treated with a bath containing 10 to 100 g / ^{l of the} compound of formula (1) in the presence of an alkali, i.e. sodium hydroxide, sodium carbonate, water glass, and the like.

The lactic reaction and the cellulose may take place directly in the bath at a temperature range of 20 to 90 ° C or plated by resting in a non-wrapped, cold-packed room in a thermal chamber. Preference is given to processes in which the bath is coated on textile materials and the composition is fixed by dry heat or steaming.

The preparation can be applied to fibrous materials also by printing technique. In all cases, suitable anient, preferably subotantive and reactive dyes, may be part of the dyeing bath.

By virtue of the compositions of the present invention, and in addition to substantially increasing the use of anionic dyes, it also achieves a significant increase in attestations for macros, i.e., in science, washing, and heel.

oellulase-based fibrous materials include cotton, linen and regenerated fibers, viscose rayon and trellis.

Compositions of formula (1) may also be prepared by direct synthesis from suitable heterocyclic nitrogen compounds of epiohlorohydrin and mannocarboxylic acid.

Example 1

After the usual pretreatment, the cotton fabric is impregnated on a bath fulary containing 30 g of N- (3-ethyneylexy-2-hydroxypropyl) -N-ethylmerfelinium hleride per g of 15 g of sodium hydroxide at a temperature of 20 ° C with a 60% baby. The fabric ae is left to stand for 12 hours at 20 to 25 ° C. Fa wash and neutralization dye on jingru.

Reactive Serving No. CI 2 at 80 ° C for 50 minutes. t ^of washing with hot and cold water color is completed. This gives a rich red color with excellent macro fastness. It is not necessary to dispense electrolyte and alkaline during staining.

Example 2

The viscose staple fabric is floated on a bath fluard containing, per liter, g of N- (3-prepaneylexyl-2-hydroxypropyl) -N-methylpiperidinium sulfate g of sodium hydroxide g Direct Blue No. C.I. 71 g urea

After gargling, the fabric is soaked at 100 ° C not hatflue and steam is fixed in a saturated steam environment at 102-105 ° C for 90 seconds by dyeing.

Passing through the spreading machine washes the alkali and finishes the dyeing.

The deep blue coloration has stability consistent with reactive dyes.

Example 3 Kercerized cotton fabric is printed with a printing paste containing in 1 kg 20 g of Direct Red No. C.I. 80 g of N- (3-benzyllexy-2-hydroxypropyl) -N-methylpiperidine chloride g sodium hydroxide

100 g urea

500 g neutral alginate thickeners

The printed fabric is steamed with saturated steam at 102-105 ° C for 10 minutes. Followed by washing by passing machine: *

1. bath water 50 ° C

2. -4. bath water 90 ®C

5. bath water 50 ®C

6. All water 20 ®C

Pure bright red printing is obtained with stability consistent with reactive dyes.

Example 4

Cotton yarn is treated on a dyeing apparatus at a bath length of 1: 4 at a temperature of 60 ° C for 50 minutes with a bath containing 1 g of N- (3-ethanoylexy-2-hydroxypropyl) -I-methyl-morpholinium chloride in sodium hydroxide.

After washing and neutralization, the material is stained at 80 ° C for 40 minutes with 1% Reactive Blue

No. C.I. 4.

Finally, the dyeing is washed with hot water (80 ° C) for 10 minutes, and finally 5 minutes with 20 ° C water. A medium saturated blue color with high fastnesses is obtained.
