Essence: at the stage of drying, the fabric is passed between the rotating surfaces under constant voltage. Rotating surface are under constant voltage of 3 to 15 C. 1 C. p. F.-ly, 1 Il. The invention relates to dyeing and finishing production of the textile industry, and in particular to methods of printing fabrics made of cellulose fibers.Known methods of printing fabrics of cellulose fibers, which consists in applying printing ink to the fabric, followed by drying and fixation of superheated steam or hot air 
Known methods of printing fabrics have the disadvantages associated with low degree of fixation of the dye, resulting in increased consumption of dyes and other chemicals, increased pollution of waste water. In addition, the stages of drying and fixing flow with low velocity.The closest technical solution to predlojeno the ke, treatment with saturated steam at 102-105aboutC for 5-10 min for active dyes and 8-10 minutes for distillation, washing regulated mode 
The disadvantages of this method are the low degree of fixation of the dye on the fabric and low, though conforming to the standards of GOST, resistance to washing and friction. One reason for these shortcomings is incomplete penetration of the dye from the surface into the fiber during the commit.The invention is directed to increasing the degree of fixation of the dye.The technical result from the use of the invention is to achieve deep penetration of the dye into the fiber, contributing to the increase in the number of fixed dye in deep micropores. This eliminates phase commit as technological operations.The invention consists in that in the method of printing cellulose-containing textile material by applying to it printing inks, drying and washing, at the stage of drying, the material is passed between the rotating surfaces under constant voltage. Pressure rotating surface are under pastime surfaces, under constant voltage, applying a printed pattern purposefully accelerates the diffusion of the dye into the fiber without additional heat and, therefore, without additional considerable amount of energy.DC provides the transfer of the dye into the fiber, making it necessary to move the particles of dye and ions of the electrolyte of the same charge (the electrolyte is always present in the printing ink) in one-way deep into the fibers, which corresponds to the increase in the number of fixed dye in deep micropores, i.e., increasing the degree of fixation of the dye. This leads to an increase color fastness to rubbing, wet treatments, etc.Processing an electric current can be performed using the device shown in the drawing.The fabric 1 is coated on its surface printed paint flow between rotating clamping surfaces 2, which with the help of graphite brushes, direct voltage. Pressure rotating surface is installed in the drying chamber 3. When passing the parcel fabric with a printed pattern closes the electrical circuit. The direction of the electric current must be tnote depends on the electrical properties of the dye (cationic, anionic).Handling a constant electric current is conducted in the drying process at the stage when the humidity of the fabric, depending on the type of the printing picture is 2-20%

Then the fabric is washed and dried on a regulated regime for this class of dyes. The result is a smooth color pink, corresponding on strength performance standards of GOST. The degree of fixation of the dye on the fabrics printed by this method, 87% Degree of fixation of the dye on the fabric printed in the classical way, is 70% with the same composition of the printing ink.
