Description

The invention relates to a process for fixing hydroxyl-containing formulations of the group consisting of starch and its derivatives, polyvinyl alcohol and soluble cellulose derivatives, characterized in that the textile materials are treated together with these formulations with a water bath containing compounds of the general formula [ Y — M — Y] ^{k +} ——X ⁿ n, (i) where k is a number 1 or 2, n is a number 1, 2 or 3,

X is an anion of a strong organic or inorganic acid,

Y is a group

CH2 — CH — CH2— \

O or

CH2-CH2-CH2

Cl OH bonded to the nitrogen atoms of the cyclic group M,

M is a five- or six-membered two-nitrogen cycle, derived from pyridazine, pyrimidine, pyrazine, piperazine, pyrazole, pyrazoline, pyrazolidine or imidazole, wherein the individual hydrogen atoms may be substituted with alkyls or hydroxyalkyls of 1-4 carbon atoms and alkali or substances alkali releasing.

The compounds of formula (1) have been designed and tested to increase the fixation of anionic dyes to cellulosic materials, to increase the stability of said dyes, and to use in non-ironing treatments of cellulosic materials. Recently, however, it has been shown that the possibilities of using the compounds of the formula I are considerably broader and that they can be applied in dyeing and fabricating textiles from all known fibrous materials.

For dyeing fibers, whether natural or regenerated, predominantly water-soluble dyes are used, using so-called substituents, which means the ability of the dye to be pulled from the bath to the fiber. Substantive dyes adhere to the cellulose fibers under the influence of hydrogen bonds and Van der Waals forces, the reactive dyes on the fiber react with the hydroxyl groups of the cellulose to form a covalent bond.

Sulfur and vat dyes are converted to an insoluble form by oxidation when dissolved in an alkaline reduction bath and drawn onto a fiber.

Materials of natural or synthetic polyamides are dyed from acid baths with anionic dyes, whereby an ionic bond occurs between the dye and the dyed substrate. Reactive dyes are also bound by covalent bonding.

Synthetic fibers are generally dyed with a group of dyes without solubilizing groups - disperse dyes. These dyes form solid solutions on the fibrous mass. In addition, the acrylic fibers are dyed with basic dyes.

Pigment dyes can also be used to dye all textile fiber materials, which are fixed to the fiber by polymeric binders.

Most of the dyeing procedures outlined above are very demanding, both in terms of time, energy and water consumption, but also in terms of strict adherence to the prescribed technology.

Particularly complicated is the dyeing of textiles from fiber mixtures, where it is often necessary to choose multi-stage processes.

The final treatment of textile materials aims to highlight some of the utility properties of the fabric. Washable preparations are generally used for the touch-sensitive treatment, whether stiffening or softening, whereby the consumer is forced to renew the desired property - softness or stiffness - after washing by dosing the softening or hardening preparations.

Permanent touch adjustments are only feasible at the cost of unbearable production costs.

The elimination of the complexity of the dyeing processes, especially in the dyeing of fiber mixtures, and the possibility of combining the dyeing operation with the stiffening and filling treatment as well as the economically available finishing touch technology are the benefits of the process according to the invention.

The invention relates to the application of the compounds of the formula I together with natural or synthetic polymers capable of reacting with the reactive groups of the abovementioned compounds. Two groups —CH2 —CH — CH2 and I

OH Cl or —CH2 —CH — CH 2 /

In one molecule of the cationic preparation, they react with hydroxyl groups in an alkaline environment, allowing not only the cellulose fibers to be crosslinked as described in the prior art, but also to crosslink fibers such as starch, polyvinyl alcohol and soluble cellulose derivatives. Thus, these fabrics can be attached to any textile fibers. At the same time, it is possible to apply a suitable anionic dye, preferably reactive or substantive, thereby producing coloration at the same time.

In the case of cellulose fibers, the macromolecules of the cellulose fiber and of the formulations - starch or starch derivatives, soluble derivatives, polyvinyl alcohol and other substances may also be linked together with the crosslinking by the compounds of the general formula 1.

In the case of non-cellulosic fibers, the treatment agents are fixed by cross-linking to the surface.

The process according to the invention offers a wide range of applications in the field of treatment and dyeing.

With cellulosic fibers, it makes it possible to achieve permanent stiffening treatments in the washing process, even in a single dyeing or optical brightening operation.

There is no need to re-solidify the fabrics so treated after consumer washing. At the same time, an improvement in wet crease properties is practically without loss of strength.

Synthetic fiber fabrics acquire improved hydrophilic properties, inhibit electrostatic charge formation by the process of the present invention, and allow surface dyeing of these fabrics with anionic dyes, the dye of course being bound to a cross-linked polymeric treatment substrate, e.g. starch, cellulose derivatives or polyvinyl alcohol . In the same way, anionic dyes can also be surface-mounted on glass fibers. The process according to the invention makes it possible to utilize these substances occurring on textile fibers from previous operations, in particular from sizing.

The advantages of the invention can be fully demonstrated by way of example only.
