The present invention relates to a novel process for finishing furniture textiles, textile floor coverings, decorative and drapery textiles, textile wallpapers of natural and synthetic materials, or a mixture thereof with chemically modified aluminoalicates, which achieves a significant improvement in the final performance properties of the aforementioned home textiles.

The use of bentonites to fill up the so-called bentonites is known from the literature to date from a wide range of aluminoeilicates. eoil repellent effect for textile materials. British Patent Epi. No. 928,689 discloses the use of Ca or Na montmoronite as such without prior treatment for the non-soiling treatment of fibers and fabrics by water dispersion, i.e. exclusively for the application of alkaline diapers. No. 177,523/78 discloses a method of and contemporaneous dirt-repellent and antistatic treatment of textile flooring with bentonite, which sticks to it an antistatic active nonionic surfactant.

Subject of US patents / see. U.S. Pat. 2 063 128 and 3 063 784 / i, the use of bentonite sol for synthetic fibers to prevent electrostatic charge build-up

Japanese Patent Epic No. 77,124,997 describes the use of smectites chemically modified with quaternary ammonium salts in the presence of three sorbitan esters for antistatic treatment of fibers.

The disadvantage of the above-described treatment methods is that the electrostatic charge formation by pure bentonite sol is insufficient, the instability of the treatment is reduced in the case of the use of naion lanzides at the expense of reducing the electrostatic charge formation. A further disadvantage is the low biodegradability of the nonionic surfactants used for

the active substance is bound to the fibers in the mentioned types of treatment only by adhering forces, so that in processes of mechanical stress, which is inevitable in practical use of textile flooring, it has to be stripped from the fiber surface · _% amectites / using ammonium aols. The disadvantage of this type of treatment is the necessity of using a dispersant which, on the one hand, causes an increase in antiethtalic activity, but on the other hand it reduces the stearate of the treatment. At the same time, there is a significant decrease in soil-repellent effect for treated material ·

Consequently, it has been the object of the invention to use modified aluminoelilicates (montmorillonite, kaolinite) for the spherical, antiethetic and antimicrobial treatment of home furnishings with high efficiency and without the disadvantages of the above processes.

It has been found that by applying aqueous solutions of ammonium compounds of formula I

The chloride, bromide, iodide or methyl sulphate anion on the textile substrate and subsequent application of aqueous suspensions of montmorillonite or kaolinite without interluding ea provides a combined dirt-repellent, antistatic and antimicrobial treatment of home furnishings.

Proposed use of modified breast repellent, antistatic and antimicrobial aluminoeilicates

229,384 home furnishings eliminate the drawbacks of the treatments used hitherto in that the addition of diapers, emulsifiers or peptides is not necessary, will substantially and will increase the soil-repellent efficacy and antiethetic efficacy of the treated fabrics.

The technical progress of the proposed treatment method is that the application of an aqueous solution of ammonium salts of the formula I to the surface of a textile material whose surface potential is normally negative (Blažej et al., Surfactants, Alfa, Bratislava 1977, s _. 151) counteracting the ammonium salt to electrostatically attract each other and thereby effectively binding the salt to the surface of the textile substrate. At the same time, at specific fiber surface sites adsorption of the ammonium salt chains occurs, in particular for ammonium aols and longer alkyl chains. As a result, the surface of the textile substrate thus treated acquires localized positive charged centers.

Upon subsequent application of an aqueous suspension of montmorillonite, the surface of which bears a negative charge due to valence unevenness / unevenness, arises from isomorphous silicon substitution in the return of tetraethers with aluminum or aluminum in octahedron layers, e.g. and is balanced by the inorganic cations Na ⁺ , K ⁺ , Ca ²⁺ , Mg ²⁺ , adsorbed on the surface of these layers, respectively. in interlayer spaces. These cations are movable and are attracted by electrostatic Coulomb ailamias to the surface of alumino-alicates. They are quantitatively exchangeable - Gregor, M., Číčel, B., Bentonite and its use, SAS, Bratislava 1969, p. 92-96), it is effectively adsorbed to the surface of the textile fibers and at the same time electrostatically attracted in the positively charged centers of the fiber surface treated with ammonium eol.

The effect of the treatment is that the binding of the treatment component to the surface of the textile fiber reduces the possibility of electrostatic charging and reduces the intermolecular diapergating and polar forces, and hence reduces the possibility of adhering the dirt particles to the treated surface.

The application of alkylammonium salts leads to improved binding of the active substance, which is a modified aluminoailicate, to the fiber surface than is the case with the use of aluminosilicate alone (bentonite, kaolin) as well as increased stability

229,384 treatment and its efficacy (enhancing non-dirty and antistatic efficacy, wherein the material gains additional resistance to microbial corrosion).

The aforementioned treatment method simultaneously improves the feel of the fabric.

It is of great practical value that the alkylammonium salts of the formula I can be applied from an after-rinse bath after dyeing or textile printing, and at the same time the unreacted and unfixed dyes are improved better, i.e., ultimately, the coloring process. The proposed method of treatment does not affect the negative color effect of home textiles, but rather increases its brilliance.

Substance of the proposed apoaob of combined dirt-repellent, antistatic and antimicrobial treatment of home furnishings and application in the application of alkylammonium compounds of the formula I in a concentration of 0.5 to 30 grams per liter, preferably 1 to 15 grams per liter of reconstituted bath 0.5 to 10% by weight of montmorillonite or kaolinite so that the resulting active ingredient loading is 0.5 to 5% by weight based on the weight of the treated textile aubatrate.

The PA carpet thus treated and applied immediately on the next fularde of 3% (w / w) and montmorillonite auepension so that the carpet weight addition was 100% (relative to the untreated PA carpet). After application aa carpet dried at 100 ° C.

The treated PP carpet aa ¹ immediately adjusts in the 4% (w / w) montmorillonite au excess and the excess amount of auapension ea is removed on the fulard so that its weight gain is 100%. The treated carpet is dried at 80 ° C.

After rinsing, aa slips on a double-cylinder fulde at maximum roller pressure. After this treatment, aa was applied to the PA carpet using a squeezer and a 4% (w / v) breton roller and an aperture of montmorillonite so that the weight addition was 15% compared to the carpets treated in the first phase. The treated carpet e dried at 100 ° C.

The treatment is maintained by shampooing and maintains its effectiveness for 5 to 7 shampooing cycles.
