Coloring Double

Double dyeing is a dyeing process in which an object is treated sequentially with basic and acidic dyes.

First, a basic dye is applied to the fibers, which is fixed in an alkaline environment. This is followed by treatment with an acidic dye, which is fixed in an acidic environment.

This two-stage coloring allows you to obtain brighter, more saturated and stable colors. In addition, the use of dyes of different nature makes it possible to expand the color range of the material being painted.

Double dyeing is widely used in the textile industry for dyeing cotton, linen, wool and silk fabrics. This method allows you to obtain a wide color palette, including complex shades that cannot be reproduced using dyes of the same class.
