BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an auxiliary coloring agent for the dyeing of synthetic materials to improve the uniformity of the dyeing of synthetic fabrics and knitted fabrics on the phase of oxyethylated products in a synergistic mixture with a naphthalenesulfonate-based condensation product. Nowadays, leveling agents are used in the textile industry to cover the polyamide materials: US Patent No. 4,563,193 discloses a dyeing aid to suppress non-uniformity of polyamide dyeing comprising a sulfonated condensation product of a hydroxyaryl compound and a quaternary ammonium compound wherein the nitrogen atom is attached one aliphatic carbon-containing radial 10 to 22 and one polyglycol chain. EP 0 121 887 discloses a process for uniformly coloring synthetic materials with disperse dyes. U.S. Patent No. 4,444,563 discloses an adjuvant and is useful in the dyeing and printing of polyamide fibers. They comprise at least one alkylsulfonate, alkylbenzene sulfonate or alkyl naphthalene sulfonate wherein the linear or branched alkyl contains 3 to 22 carbon atoms and one quaternary ammonium compound wherein the nitrogen atom is an aliphatic 10 to 22 carbon atom and the polyglycol ether chain is - C - C - O -, where one of Y 1 and Y 2 is hydrogen and the other is phenyl | radical.

Japanese Patent 6,241-184-A discloses a composition for coloring natural and synthetic polyamide fibers obtained by reacting an alkyl amide with ethylene oxide and / or propylene oxide.

French Patent 2,574,791 discloses fatty amine sulfates, their preparation and use for dyeing polyamide fibers. USSR patent 953048 discloses a composition for coloring PAD products. The composition comprises a coloring agent and an org. solvent.

Japanese Patent 6 2085-080-A discloses a water- and oil-dispersible blend for leveling dyeing of polyamide fibers. In the textile industry, glycol based dye auxiliaries with a wide polydispersion can cause the temperature of the dye bath to become unstable in a certain temperature range, thereby causing the dye aggregates to be unevenly spread on the textile substrate and causing dull staining. The quaternized fatty amines have a high affinity for polyamide fibers, which can cause streaking in the case of filament-affinity filaments when not adhering to dosing and temperature-time. Dyestuffs for coloring polyamides mainly with a small molecule, CS 2.77250 Β6 2 Μ, for example: CI.ACID ORANGE, have a high affinity for polyamide fibers, thereby highlighting the difference in affinity between fibers for staining.

These drawbacks are solved by the auxiliary coloring agent, the coloring of synthetic materials, to improve the uniformity of the coloring of fabrics and knitted fabrics, the essence of which is to contain from 20 to 40% by weight of an oxethylated unsaturated acid of from 14 to 20 carbon atoms and from 15 to 20 moles of ethylene oxide. 30% by weight of a sodium salt of a condensed naphthalene sulfate with formaldehyde, 20 to 40% by weight of an oxethylated amine having 12 to 20 carbon atoms and a content of 15 to 25 moles of ethylene oxide and 20 to 40% by weight of water.

The aforementioned auxiliary coloring agent forms a balanced mixture which, in the given proportions, forms a water-soluble homogeneous liquid diluent which is hot water-soluble and stable at a temperature range of -5 to 100 ° C without loss of homogeneity. In the auxiliary dyeing agent, the properties of the individual components and, alternatively, to counteract the affinity differences of the polyamide fibers, are synergistically influenced. Example 1

150 L of warm water is charged into a 420 L agitator and 76 kg of sodium salt of the naphthalene sulfate condensation product is added with photmaldehyde. While stirring, the mixture is heated to 90-95 ° C and stirred until complete dissolution of the product. After the heating is stopped, 134 kg of molten oxyethylated amine of carbon atoms 12 to 20 and 15 to 25 moles of bound ethylene oxide are added. Subsequently, 40 kg of unsaturated fatty acid having carbon numbers of 14 to 20 and 8 to 20 mol of bound ethylene oxide are poured in. The mixture is homogenized and cooled with stirring. Cool to 35 ° C into pre-packaged containers. Example, No. 2

1.5 g / l of the composition prepared according to Example 1, diluted in 10 times the amount of warm water, 2 g / l of ammonium sulfate, is charged into a jet dyeing apparatus with a load of 120-140 kg polyamide fabric. and a dye mixture: 8% CI ACID RED 1140.14% C.I. DISPERSE YELLOW 230.8% C.I. DISPERSE RED 60 The staining results in a uniformly brilliant PAD staining. Example 3

To a coloring Jiggra with 150 to 180 kg of PAD tissue is metered into 1.times.1.5% of the composition prepared according to Example No. 1 pre-diluted in a 10-fold amount of warm water and 2 g / l of ammonium sulfate and dye are added. 1.8% C.I. DISPERSE BLAU 81 1.5% C.I. ACID BLAU 129 Dyeing results in a calm uniform blue staining.
