The present invention relates to a leveling composition based on oxoethylated and propoxylated products in synergistic admixture with a sulfated fatty alcohol for polycarbonate polyester and polyamide textile materials.

Currently, the textile industry uses diapering and leveling agents:

2250 225 587 ČSSR discloses a leveling agent for dyeing synthetic textile materials with water-insoluble dyes based on glycerides of higher fatty acids and oxoethylated resin acids based on alkyl homologues of phenanthrene and aliphatic alcohol.

PAT 1,583,966 Gr. Brit. and discloses dispersing and leveling agents for polyester materials based on soluble and dispersible copolyestres having a mol. wt. 600-5000 enriching carbon and sulphonated salts.

PAT 7629 572 Jap. protects the dyeing of polyester materials using benzyl alcohol and aliphatic alcohols.

Glycol-based auxiliary dyes with wide polydioperity can cause dyeing bath instability and, if used, CI Disperse Yelow 23, CI Disperse Yelow 42, CI Disperse Red 121 inequality '. A further disadvantage is that, upon cooling, dye molecules are aggregated which have not been pulled onto the textile substrate during dyeing. When dyeing ea, we often encounter the foam of the dyeing cup, which adversely affects the leveling of textile materials.

The above-mentioned drawbacks are overcome by the leveling-migration composition according to the invention, which comprises 20 to 40 wt. % of a branched alcohol C8 to C8 preferably sθ and bound 5 to 9 moles of ethylene oxide with (EO) preferably 7 EO, 10 to 30 wt. % Unsaturated fatty acid Cg - C _20, preferably C _1Q of 10 to 15 moles of EO; 5 to 15 wt. of a linear saturated fatty alcohol sulphate of C ₁₀ to C ₁₂ , 10 to 30 wt. % of EO-coupled nonylphenol and propylene oxide (PO) in a ratio of 2: 3 and 10 to 30 wt. % water.

The described leveling-migration device constitutes a balanced mixture which forms a water-soluble, homogeneous liquid mixture in the poraers. The use of leveling-migration means will improve the uniformity of dyeing of textile materials and reduce the fixation time of the disperse dye.

Another advantage of the leveling-migration composition is the high stability of the blend when stored from -20 ° C to + 50 ° C without loss of homogeneity. With shorter baths from 1 to 6 to 1:10, the effect on the increased solubility of dyes is better reflected.

200 kg of water are pumped into the mixing boiler and heated to 50 ° C, 300 kg of higher branched alcohol Cg to Cg with 5 to 9 moles of EO are added, 100 kg of linear saturated fatty alcohol sulphate. After perfect mixing and dissolving approx. 30 min. the other components were added: 200 kg unsaturated fatty acid ^C 18 ^with 10 to 15 moles of EO and 200 kg of nonylphenol b binding of EO and PO in a ratio of 2: 3 was raies for 20 minutes with gradual cooling to 30 ° C. The product at 30 ° C is discharged into the prepared eudes. CS 274084 Bl Example # 2 Composition prepared according to Example δ. Dissolve 10 g in 10 times the amount of water and dispense into the horizontal dyeing apparatus at 1.5 g / l dye bath, disperse the dye to the desired shade. Ex: 0.015% Teraailgelb 4 G 0.025% Foronrubin RD-GFL 0.017% Foronblan RD-GL for the amount of stained material, pH adjusted to 4.5-5.0. The high pressure dyeing procedure provides optimal leveling of the PES substrate. Example # 3 Composition prepared according to example δ. 1 is dissolved in ten times the amount of water and dosed with Ba into a horizontal dyeing apparatus in an amount of 1 g / l of dyeing bath, 2 g / l (NH4 / gSO4) is added. For example, a Rylan bordo B. Staining at 98 ° C achieves even uniform staining of the PAD substrate.
