Description

I

The invention relates to the field of the dyeing and finishing industry, namely to the composition for dyeing natural suede and velor products.

A composition for dyeing velor and suede products is known, consisting of an acetone soluble dye, acetone and ethyl cellosolve 1.

The disadvantage of this composition is the necessity of dressing, after dyeing, which complicates dyeing technology.

A composition for dyeing velor and suede products is also known, consisting of a water-insoluble dye or pigment, a polyurethane polymer, acetone and dimethylformamide 2.

The disadvantage of this composition is the use of a toxic organic solvent, which impairs the working conditions.

The closest to the proposed is the composition for dyeing products

Of natural suede and velor containing dye - indulina mixture with fat-soluble or alcohol-soluble nigrosine AZO dye brown fat soluble sizing additive, glycerol ester of rosin-maleic adduct plastifikator- dibutyl phthalate, and solvent - ethyl cellosolve, with the following ratio of the starting components,

May 10 %:

Fat-soluble Indulin O ,, 0 Soluble Alcohol 0, 0

Glycerol ester can15 folno-maleic adduct0, 2-1,5

Dibutyl phthalate 0.05-1.0

Ethyl cellosolve Else A disadvantage of the known composition is the complexity of the dye technology, due to the use of flammable and toxic organic solvent. In addition, the colors produced by dyeing natural suede and velor with a known composition have a sheen. This effect of bronzing is a significant disadvantage of colored products. The purpose of the invention is to simplify the dyeing technology and eliminate the effect of bronzing. The goal is achieved by the fact that the composition containing the edge, the sizing additive, the plasticizer and the solvent contains, as a dye, an acidic metal containing a dye of a 1: 2 complex, in which the finishing agent is leaded peat or brown coal wax, as a plasticizer monoethanolamide, as a solvent, ethyl alcohol and additionally ammonia solution in the following ratio of initial components, May. %: Acidic metal-containing dye of complex 1 1.2 2.0-2.5 Hydroxyethylated peat or brown coal 0.2-0.5 wax 2.0-2.5 Moethanolamide 2.0-2.4 Ethyl alcohol 25% - ammonia solution 1, 5-2.0 Water Remaining The above composition for dyeing isels from natural suede and velor is obtained by mixing the starting components, and a water dispersion obtained by mixing asphalt, ethoxylated peat or brown coal wax is added to the composition at 70-80 ° WITH. Example 1. An acidic metal-containing dye of the 1: 2 complex (for example, wofalan black BL, wahfalan brown wofalan ruby RL) is rubbed with an ammonia solution, the resulting paste is dissolved in water. C and mixed with a solution of monoethanolamide in ethyl alcohol at 90 C, ethoxylated peat Noel or lignite wax with an acid number of 5 mg con / g, dropping temperature not lower and degree of oxyethylation 57-85 melted at 97-100 ° C, mixed with water heated to 70-80 ° C, the resulting aqueous dispersion of wax is mixed with a solution of asitel. The compositions are obtained for dyeing at the following ratio of the initial components, May D, listed in Table 1. Table 1

Example 2. Comparative tests of the known and proposed i compositions of dyeing of the upper of the shoe made of natural suede and velor using the pelamic method, s

The coloring technology includes the following operations: removal of saline spots from the skin surface (if necessary); shoe polishing with white spirit; drying at room temperature; O during the day; treatment with 1-2% surfactant solution

Indicators

Appearance of the surface after brushing

Organoleptic characteristics (by touch)

Water resistance (by absorbing a drop of water by the surface for 10 minutes)

Marking (by repeatedly wiping the surface with a white napkin)

Claims (3)

Colors of coloring As follows from examples and tab. The proposed composition for dyeing from natural suede and velor makes it possible to improve the technology of dyeing and to eliminate the effect of bronzing the color. DETAILED DESCRIPTION Composition for dyeing natural suede and velor products containing a dye, a finishing agent, a plasticizer and a solvent, about 156 substances (for example, OP-7, OP-10, Sintamide-5, Sintanol-DS10, etc.); painting the surface with a paint composition by rubbing it with a brush; drying shoes at "O- + Z C; the final finish by raising the skin lint with a needle tape and removing the unfixed dye with a stiff brush. Properties of painted products from natural suede and velor are given in table. 2 table 2 Composition Proposed Famous The surface is uniformly colored, glossy When you hold your hand over the surface there is a fatty shine, the pile is laid Also Insignificant Only black, brown color is not provided by the fact that, in order to simplify the dyeing technology and eliminate the effect of bronzing, the composition contains acid metal-containing dye of the 1: 2 complex as a dye, ethoxylated peat or brown coal wax as a coupling agent - monoethanolamide, and as a solvent ethyl alcohol and additionally ammonia solution in the following ratio of initial components, wt%: Acidic metal-containing dye of 1: 2 2 complex, 0-2.5 Oxyethylated peat or bile-coal 0.2-0.5 wax Monoethanolamide 2.0-2.5 2.0-2, Ethyl alcohol 25% solution am1, 5-2.0 miaka Water Else 90 58 Sources information taken into account during the examination 1.
