The invention relates to the field of art and color design of textile products by means of low-temperature hand-painted (cold batik) and fotofilmes.

In accordance with these methods, the process of painting fabrics of various fibers as follows: on the tissue through the mesh pattern or by means of a glass tube is applied to the circuit of figure and once it was fixed (heat treatment at 40 - 50oC) traditional hand painted squares, bounded by the contour of the figure, the ink composition containing a dye and auxiliary substances. While the outline of the figure should be impervious to used ink composition.

Alternatively, after the deposition and fixation of drawing contour cloth moistened and immersed in the dye solution (cold, warm or hot) for 10 to 40 minutes. For fixing a dye after painting and drying fabric zaparivaetsya in the atmosphere of wet saturated steam, washed and finally dried /Koryukin Century. N. Batik. Decoration fabrics. - L., 1978, 135 S./.

Forming a contour image can be made hot and holodynamics, paraffin, technical petrolatum, rosin). This invention relates to a method of low-temperature formation of the circuit pattern, the implementation of which apply formulations containing large amounts of organic solvents (gasoline, white spirit, solvent 2) /Armand T. A. Ornamentation of the fabric. - Leningrad, 1931, 330 S. /(PL. 1).

Rubber adhesive is dissolved in the gasoline (or other solvent), enter the other ingredients and heated with stirring on a water bath. In this method, the reserve remains on the fabric and if necessary you can change the color by adding oil paints that are compatible with the solvent /Armand And So, the Guide to fabric painting. - St. Petersburg, 1992, 63 S./. To reduce the amount of solvent in the composition may be applied to the formulation of paints with the following ingredients, wt.%: paraffin - 2.8; rosin - 3.8; petrolatum technical - 1,4; oleic acid 2.0; soda ash (13.3% aq water) - 1.7; turpentine - 1.0; tregenna of sagasti up to 100. The disadvantage of this structure is the high concentration of alkaline agent, limiting its use for painting fabrics made of protein fibers.

Closest to the claimed composition is the surrounding of the following components, wt.% /Pomansky B. A., Friedman N. I. and other Technology of fabric painting. - M.: 1957, 136 S./:

Rubber adhesive (thickener) - 50.0

Paraffin (repellent)

Rosin (water repellent) - 0.75

Kleinova acid (softening agent) - 0.06

Vaseline technical (softening agent) - 0.06

Pigment - X

The solvent (gasoline, white spirit) - Up to 100

The preparation of the specified solution is made by heating a mixture of components in a water bath (55 - 65oC) with constant stirring. Before applying the composition to the fabric, it is recommended to put the wash in the soda solution of synthetic detergent to remove impurities and possible surface sizing. When applying contour drawing by hand, the fabric must be in a horizontal tight taut that is stretched on a wooden frame with a sharp needle length 3 4 see In this case, the circuit is applied to glass tubes with different diameter of the outlet, determining the thickness of the contour lines. Alternatively, the contour pattern is formed on the technology of traditional fotofilmes using mesh pattern and wiping the back of composition through a flat sieve in several passes ralestone of fabric painting is a painting background, limited by the contour of the figure, the ink composition containing a dye and excipients necessary for obtaining solid colors. The composition of the ink composition includes dyes of different classes (direct, acid, basic, active, acid or alkaline agents, wetting and dispersing agents, intensifiers, and other additives target. Such compositions are intended for painting fabrics of various fibers (protein, polyamide, viscose, acetate and others). For fixing a dye fabric after painting are safely packaged in an atmosphere of wet saturated steam under pressure at a temperature of 102 - 108oC for 15 to 60 minutes followed intensive rinsing the tissue with the use of detergents and drying in natural conditions.

The main disadvantage of reserve staff is content of large quantities of organic solvent, which creates serious difficulties in its preparation and application due to the explosive and fire hazard volatile gasoline vapor (white spirit), poor working conditions, represents a danger to health personnel. The basis of the backing composition is a rubber adhesive, viscous rasna sieve template), which adversely affects the quality of contour drawing. Having a high water-repellent properties, the composition when it is applied to a thin fabric increases their rigidity (with a sufficiently large amount of contour lines). The presence in the composition of gasoline, paraffin, rosin and oil paints an adverse effect on other measures of quality paintings and consumer properties of finished products (halo color, odor solvent, a long drying pattern, and others).

The technical result of the invention is to improve the quality coloration appearance of tissues by improving the rheological properties of the back contour of the structure while ensuring the security of the process of painting by excluding the use of explosive and flammable and toxic organic solvents.

This object is achieved by the application of the proposed technical solution back contour of the composition is water-based in the combining and individual manifestations of the positive qualities of its constituent substances at the following content, wt.%:

< / BR>
The mineral pigment black is a product obtained from the purified gas soot with the necessary auxiliary additives.

The pigment concentration is selected based on the requirements of the artists in the color we paint composition.

2. Precondensed thermosetting resin (ATGM) - used in the inventive composition as a cross-linking agent. The best results are obtained prelamin with the contents of the group-NH-CH2OC2H4OH

As softener is recommended to use a polyethylene emulsion (25% dry residue ) at pH 7 - 8 /Melnikov, N. N., Zakharova So on Modern methods final finishing of fabrics of cellulose fibers. - M., 1975, 240 S./. Featured in the claimed technical solution, the concentration range glicazide due to its optimal ratio of thermoplastic polymer (latex), which gives high strength and adhesion indices of total film. This provides the necessary stability of the contour lines of the drawing to external influences.

3. Synthetic latexes are used in the inventive composition as a film-forming component. Together with ATGM contributes to the message of the contour lines of the properties of vodorastvorimostew and water resistance to ensure a strong adhesive to secure the fibers. The best properties have defininitely karboksilirovanie latexes, whose characteristics are presented in table. 2. /The range and properties of the latexes produced in the USSR and abroad. Browse Tsniiteneftekhim, 1978, 132 S. //Erkov L. N., Chechik O. S. Latexes. - L., 1983, 208 S./.

4. The water-repellent agent: intended for at the.

4.1. Fluid 136 - 41: the organosilicon compound (acylhydrolase), viscous (45 - 200 CST. 20oC) colorless oily liquid with a density of about 1 g/cm3, pH = 6, contains 1.3 - 1.4% of active hydrogen /Grausman O. N. Chemical materials, dyes and detergents. - M.: 1985, 262 S./.

Preparation of 30% emulsion fluid 136 - 41 is carried out by adding a calculated quantity of the drug to the previously prepared 2% final solution of emulsifier (Alcamo OC-2), followed by stirring by a propeller stirrer (3000 min-1within 7 - 10 min /Arkharov A. A. Printing and finishing of fibrous materials. - L., 1984, 128 S./.

4.2. Alamin With: the product of condensation of methylaniline N-oxymesterone. The process of film formation of the polymer takes place under mild heating (50 - 60oC) for several hours in the presence of a catalyst is ammonium chloride (2 - 5 g/l). /TBB directory and Ed. Ivhimprom. Ivanovo, 1995, 36 S./.

Preparation of a 20% dispersion alumina C is made by adding 20 g of the product of 60 to 70 ml of hot water, followed by stirring on a water bath for 5 to 10 minutes then added 5 ml of 40% acetic acid and AC the mixture is added to hot water (100 ml) and after stirring the resulting dispersion is stable for 24 hours. The optimal concentration of the water-repellent agent (0,12 - 3.4 wt. %) determined experimentally when evaluating water-repellent properties of the proposed structures.

5. Catalysts: as potentsialnykh catalysts with sufficient effectiveness at temperatures of 40 - 60oC. In the inventive composition may use the following substances: ammonium chloride (GOST 2210-73); uranyl magnesium chloride (GOST 7759-55); chloride of zinc.

Recommended concentration of catalyst (0.6 to 1.0 wt.%) provides the necessary degree of their influence on the processes of intermolecular crosslinking polymers at temperatures not exceeding 60oC. /Tikhomirov Century B. Chemical technology of production of nonwovens. -M., 1971, 320 S./.

6. Thickener: methyl cellulose (MC). Used to create the required viscosity of the inventive composition and message him for more water resistance.

MC is a simple cellulose ether and methyl alcohol; the most suitable for the claimed composition mark MC with a degree of substitution of 40 - 200. When the temperature rises to 50 - 60oC aqueous solutions MC prone to gelatinization and thermocoagulation with the transition in water-insoluble sottoriva state by reaction with ATGM. / Encyclopedia of polymers. so 2. -M., 1974, S. 211./. The optimum concentration of MC provides a clear outline of the figure when it is applied to the fabric hand and machine methods. In the first case it is 3.5%, the second 5% in aqueous solution.

Thus, all components of the inventive composition on a water basis is chosen so as to ensure the transition is formed on the fabric contour drawing in water-insoluble (waterproof) state by heating the material to a temperature of 45 - 55oC. This achieves the proof of contour lines in the process of fabric painting, water coloring compositions. Education waterproof circuit due to the following reasons: the ability of the MC to thermocoagulation and gelatinization transition in water-insoluble state; the formation of films by the water-repellent agent with a high water-repellent ability; the reactions of polycondensation ATGM and its interaction with macromolecules latex at a temperature of 50 - 60oC with the formation of spatial water-insoluble thermosetting structural connections. The potential increase in the stiffness of the fabric with a large number of contour lines is compensated by the presence of the water-based to obtain a tight outline of the picture when the art of painting fabrics of various fibers:

Then fabric with printed outline of the figure was painted traditional solutions ink compositions using an active, direct, acid, basic, and other dyes. After this operation was carried out steaming fabrics under pressure at a temperature of 102 - 108oC for 15 to 60 min, rinsed in solutions of synthetic detergents and drying in the air.

In table. 3 shows the comparative characteristics of the rheological parameters, and featured well-known compositions for drawing the contours of the figure. Analysis of these data shows that the necessary complex rheological properties of the inventive backing compositions which these indicators exceed the compositions specified in the prototype (best turnover, a higher degree of thixotropic recovery patterns, less structured).

The quality of the contour pattern obtained with the use of these compositions when applied manual and template methods tissue was assessed in terms of sharpness of outline, its permeability, adhesion to the substrate and untouching table. 4 shows that the values of the sharpness of the contour of the figure, its permeability, adhesion to the substrate and resistance to friction featured compositions give the best results in comparison with the prototype for all of the tested tissues. At the same time there has been no increase in the stiffness of tissues.

High quality coloration clearance fabrics at their butilirovaniya featured compositions confirmed by the results of the production tests at the factory art of fabric painting AOOT PHO "North" (St. Petersburg). When carrying out the proposed process, along with the improvement of product quality, there has been a marked improvement in working conditions with the exception of gasoline backup compounds. Confirmed, convenience and security with the proposed contour colors in the stages of their preparation, application and fixation on the textile material.
