bonded to the nitrogen atoms of the cyclic group M,

M is a 'five- or six-membered cycle' with two nitrogen atoms; derived from pyridazine, pyrimidine, pyrazine, piperazine, pyrazole, pyrazoline, pyrazolidine or imidazole, wherein the individual hydrogen atoms may be substituted with alkyls having a carbon number of 1 to 4.

The recently published and patented series of reactive quaternary ammonium compounds that mediate dyeing of cellulosic fibers with anionic dyes justifies the assumption that dyeing by so-called cationic preparations is increasingly important and will represent a significant rationalization benefit in dyeing technology. These substances react in an alkaline medium with the hydroxyl groups of the cellulose to form a 'covalent bond,' and the quaternary ammonium group subsequently binds an ionic dye.

The prior art cationic preparations can be represented by the general formulas

The advantage of all these compounds is that they can achieve increased dye utilization in subsequent dyeing, increase dyeing stability, reduce process water demand and simplify dyeing process.

All of these advantages are also met by the compounds of formula (1) which, unlike the compounds of formulas (2) and (3), have two active groups. This gives them greater efficacy and some other advantages, since such compounds can react with the two hydroxyl groups of the cellulose and cause crosslinking thereof, or they can react appropriately. A dialkyl, alkyl or a simple amino group of the dye together with the hydroxyl group of the cellulose. This can be done. achieve - on cellulosic materials in. one operation simultaneously increased. dyeability and final non-iron or non-crease finishes. It is also possible, for example, to dye the two components of the polyester / cellulose fiber mixture with a suitable disperse dye.

While the application of the compounds of formula (1) before and during dyeing increases dyeing stability and dye utilization, post-dyeing treatment is only coloristically accompanied by an increase in dyeing stability.

However, the effect on the recovery of textile materials does not depend on whether the fixation of the preparation occurs before, during or after dyeing.

Processes in which the composition and the cellulosic fiber react in a swollen state, i.e. wet, provide a significant improvement in wet recovery. Improved crease and dry recovery results in dry application methods.

A particularly pronounced effect with the compounds of formula (1) is obtained when the cellulosic material is pre-impregnated with a water bath containing 150 to 350 g / l of sodium hydroxide, whereupon the material is treated without washing with solutions of said compounds. The use of the compounds of the formula I relates not only to purely cellulosic textile materials but also to mixtures with synthetic fibers, in particular polyamide, polyester and polyacrylonitrile fibers, where the process simplifies dyeing and finishing.

The importance of the invention is also illustrated by the possibility of dyeing mixtures of synthetic, especially polyester and cellulose fibers with a disperse dye, the so-called thermo-isolation process, in which dyes containing both primary, secondary and tertiary amino groups bind the dye to the cellulose fiber. · 1 ..

Compounds. The formula 1 can be used as both coloring agents and crosslinking agents in special treatments.

In dyeing technology, cellulosic materials can be treated with alkaline solutions of the compounds before dyeing, simultaneously with dyeing or after dyeing.

Before dyeing, the cellulosic materials are treated with compounds of formula 1 from long baths at a temperature of 30 to 60 ° C, or more preferably impregnation processes, wherein the reaction with the cellulosic fibers occurs in an alkaline environment by simply lying down at 20 to 30 °. C, at elevated temperature, the aging time is shortened, or the reaction is accelerated by passing the textile material through the steam medium or by drying and brief processing in the temperature range of 100 to 230 ° C.
