There is a known method of forming a fabric pattern after it is impregnated with a dye solution, followed by pressing.

In order to simplify the technological process of pattern formation and save the dye using the proposed method, the pattern is obtained by contacting a fabric impregnated with a dye solution with a metal heated surface, having a specified pattern obtained by embossing, equated or etched.

In the practice of finishing production, the method of multicolour patterned fabric coloring is widely applied by applying an inoculate paint to the fabric by means of engraving rolls or photo-film-printing templates.

This is based on the ultraviolet dyeing of materials, covered with a layer of diazo compounds under the original, and the subsequent development of the pattern by thermal action.

The proposed method is based on the redistribution of the dye, a patch of raw cloth, due to its contact with a heated metal surface having a convex pattern.

When this occurs, the dye migrates from the place of the fabric where it is heated less to the places where it is heated more, creating a different concentration of dye in

these places, which leads to the formation of patterns on the fabric.

This method does not require the use of photosensitive materials to create a pattern and ultraviolet illumination.

The formation of the pattern according to the proposed method is carried out by touching the fabric, implanted with the dye solution, to a hot one, heated by electricity, steam or

another coolant surface of the cylinder with a funk 11m rnsuikom. The convex pattern is tentacle woven upon contact with a hot surface. The heat transfer rate changes due to

occurrence according to the applied

convex pattern of air gaps, holes,

between the hot surface and the tissue to be dried.

The proposed method of forming a pattern

scored on four samples.

Sample 1 is impregnated with low-substance active gels, for example, portions with black HS (concentration 20 g / l) containing auxiliary substances necessary

for fixing the dye (15 g / l of sodium bicarbonate, 100 g / l of urea). Next, an 80–100% spin extraction is performed, then the specimen is contacted with a cylinder having a relief pattern. In this case, contact with the cylinder occurs during 4 seconds, the temperatures of which. 3 Sample 2 is impregnated with a solution of phthalocyanogen blue 43M pressed. Contact with a hot cylinder with a temperature of 160 ° C occurs within 5 seconds. Sample 3 was printed on a printing press c5 by applying a multi-color pattern, after which it was rawly directed onto a cylinder, contact with a cylinder having a temperature of 160 ° C, continued for 4 seconds. Sample 4 is impregnated with a solution of low-volume Yu of the standard Nitol (for example, Nitol) and after pressing enters the same corrugated heated cylinder, and then without final drying, on a solution of some diazole, for example, a pink OAZ diazole. 4 The pink O is used the same as that used for the krasheini fabrics. Method of forming a pattern on a fabric after it is impregnated with a dye solution followed by pressing, characterized in that, in order to simplify the pattern formation process and save the dye, the pattern is obtained by contacting the fabric impregnated with the dye solution with a metal heated surface having a given pattern, obtained by embossing, engraving or etching.
