The proposed compounds are burgundy-colored dyes.

Dyeing pulp and paper fiber.

Dyeing is carried out by padding the fabric at 50-55 ° with a dye solution in water (30-40 g / l), squeezing and passing through soda solution .. (5 g / l) at 40 ° C, then washed with hot and cold water . .

Dye

727664

Test the strength of the colors carried out according to GOST 9733-61.

The obtained color showed high strength to various types of treatments.

Dyeing polyacrylonitrile fiber (Nitron).

Nitron was dyed from a bath containing propylene carbonate (50 g / l). Bath module 50. The sample was placed in a dye bath at 5060 C for 15–20 min, then the temperature was raised to a boil and dyed for 1 h. The painted sample was thoroughly washed with hot water, detergent solution, cold water, and dried. The test of the strength of the paint is produced according to GOST 9733-61 ..

The obtained vykraski have high strength to various types of treatments.

 An important property of the synthesized compounds is the high strength to dry cleaning, washing and light, and that the versatility of application is especially valuable. They allow dyeing both polyacrylonitrile fiber (Nitron) and cotton fabric directly from aqueous solutions, while maintaining the high strength properties of dyes to the physicochemical effects (table). This is especially important from the point of view of application to mixed-fiber fabrics.

Indicators of the strength of colors to physicochemical effects are given in the table.
