A small amount of subtle light irregular lines on a dark blue background and a white background on printed areas were obtained.

thickener SPE-90S applied thickener Manutex RS 3%. A small amount of subtle light irregular lines against a dark blue background was obtained on the fabric.

PRI me R 10. (Prototype). On PE fabric art. 52363 was applied through a printing template of MRI sodium silicate beats. weights of 1.44 and dried (It should be noted that during the application of BP to the fabric, the printing template very quickly dried out and was poorly washed). After drying, the fabric was washed and printed with the printing ink of the composition indicated in Example 1. After drying, superheated steam was matured.

5 at a temperature of 160 ° C for 8 minutes The washing was carried out by the method specified in the prototype, i.e. in a solution of 5 g / l soda ash at a temperature of 40 ° C and, optionally, at a temperature of 80 ° C

0 for 10 min, with the addition of 1 g / l of detergent. A small amount of dark irregular lines was obtained on a white background with a yellowish tint, along with a dark blue background on unprinted places with PB.

It should be noted that imitation of batik by the proposed method is obtained in mirror image in comparison with the prototype. This is explained by the fact that a reserve substance is applied to the fabric in a prototype manner, in which cracks are formed upon crushing and the printing ink penetrates the fabric only at the places of the cracks and the entire fabric background remains unpainted. According to the proposed method, a solution of copper sulfate applied by plusing does not prevent the penetration of printing ink onto the fabric, but only when the ink is crushed in places where the ink is crushed,

In our case, the entire background of the fabric remains dyed, and in the places of cracks - unpainted. The quality of the batik effect was compared and visually evaluated by both methods and by the number of irregular lines in dm 2.

5 The quality of the batik effect (the number of irregular lines) was determined visually and on a peer-to-peer system. From the table. 1 shows that finished according to the proposed method, the fabrics (examples 1, 2, 3) have

0 good batik effect (a large number of brightly expressed irregular lines).

From the data table. 1 it follows that the batik effect depends on the concentration of copper sulfate in solution, which is optimal in the proposed method. As follows from example 5, lowering the concentration of copper sulfate in solution below 2.5 wt.% Significantly reduces the effect of batik (a small amount few noticeable lines). An increase in the concentration of copper sulfate above 3.5% (Example 4) causes the batch effect to disappear and white spots are obtained instead of irregular lines.

In the table. 1 presents data using other thickeners (examples 6, 7, 8, 9). Examples show that other thickeners do not provide batik effects.

Thus, the data in Table 1 confirm that the set of essential features set forth in the claims, i.e. paint with hardener Prisulon SPE-90S 8% in interaction with copper sulfate applied to the material provides a qualitative batik effect.

Similarly, results are obtained with other brands and concentrations of dispersed dyes (see table 2).

The data table. 3, according to the strength characteristics of the stains, show that the resistance to solutions of soap, sweat, and friction of the proposed method and prototype are almost the same, and the resistance to -. the light of the proposed method is 0.5-1 points higher than the prototype.

From the foregoing, we see that the present invention in comparison with the prototype allows 3-5 times to increase productivity, as well as significantly

simplifies the process of colorizing weavers with the effect of imitating batik.
