Known apparatus imparts porosity aramid fabrics that allows you to paint them a different color without dye carriers and means causing swelling of the fibers, and can also be used for processing threads.

The fabric with the guide shaft comes to the clamping shaft which is in contact with a hole in the stationary drum. The latter is located inside the spiral, and the space is filled with small and large particles coming through the pipeline. The pipe in the drum enters the air with transonic speed, which results in the motion of a particle, with great speed acting on the fabric. After turbulence using a spiral air goes up the chimney. For a more snug fit fabric to the hole on the body of the drum are elastic strip.

For reasons that impede the achievement of specified following technical result when using the known device is that in the known device is used for the propulsion of particles KRA is Italia the air with transonic speed. For powder-coating on the yarn or thread is inappropriate, it is better to use the upward gas flow in combination with vibration, as in the claimed invention. In addition, more appropriate thread to pass through a chamber filled with powder to dye than to apply the powder through the hole in the drum, as in the proposed apparatus. As it passes through the chamber with the dye, the surface area of interaction between threads and powder more than when applying the powder through the hole.

Known apparatus for applying powdered polymeric materials in suspension layer including camera work, the porous partition, the air chamber (see Vloc, NR. Ratnikov, Pggosin. Staining techniques industrial products. Moscow, "Chemistry", 1975).

This machine is used for finishing the polymer coating small articles of simple shape.

To obtain coverage based on the ability of a fixed volume (layer) of the powder to move in suspension under the influence of the upward flow of gas, vibration or stirring. Thus, the powder particles are separated and acquire a greater degree of freedom than in a fixed bed. Inside the layer of the powder, there is intense movement of individual particles. In this fluidized bed, the product is placed, the surface of which is heated to a temperature higher than the surrounding temperature of the melt film-forming (polymer). Powder particles colliding with the heated surface, settle and melt it, forming a film. Then, the product is removed from the tank and move to the oven for further melting, after which the coating is cooled, which is the final stage of its formation.

For reasons that impede the achievement of specified following technical result when using the known apparatus is that in the known apparatus requires preheating of the product. Significant heating temperature of the product can cause degradation of the applied powder material. For powder-coating on the yarn or thread is inappropriate, better pre-skip the thread through the bath, in addition, it is better thread to pass through the chamber to ensure an even and regular application of powdered dyes on the thread, as in the claimed invention.

A device for the continuous impregnation of the strands, including zapasnoy camera, impregnating bath (see application France 2624142, IPC4D 06 3/06).

In this device the thread from the reel of coiled, using the staking rollers passes through the impregnating bath, and a pneumatic device located in the chamber. After processing, the thread in the form of spirals placed on a conveyor passing through a drying and zapasnoy camera, with the purpose thermo is axali dye before winding. The processing threads in the tub is made of dye solution. The excess solution is removed in Timna device using compressed air. The excess solution flows through the bottom of the camera and enters the recovery tank. Using an electric valve regulates the access of the solution in the chamber, which serves for heating using steam line connected to a control valve with a source of steam. The control valve is carried out by using the temperature sensor.

For reasons that impede the achievement of specified following technical result when using the known device is that in the known device is the migration of the dye on the fibers, arranged in a spiral, during the heat treatment, resulting in not achieved rowdata staining also require heating of the dye solution, which increases the energy consumption.

The closest to the technical nature of the claimed invention is selected as a prototype device for dyeing cotton yarn and threads powder dyes in a mixture with hydrotropism substances, including zapasnoy chamber, a cylindrical casing, a screw mixer (see U.S. Pat. Russia №2239678, IPC D 06 1/02).

This device is intended for continuous dyeing of yarn or thread. The operation of the device is as follows: it is resolved, sativas from the reel passes through zapasnoy chamber, then through the elastic cuff gets inside the cylindrical body, where the inside controlling powder rotary screw mixer on its axis. Screw mixer does not give the powder to cake and creates within the cylindrical body, a weighted layer of powder deposited on the wetted thread. Depending on the time spent by threads within the cylindrical body changes the intensity of the staining. Then thread through the hole in the upper part of the cylindrical body, with elastic cuff goes out of scope staining and can be subjected to further heat treatment.

For reasons that impede the achievement of specified following technical result when using the known device, taken as a prototype, is that structurally it is difficult to make the passage of the threads inside the rotating auger on its axis, and the complexity of manufacture of the drive mechanism of the auger. In addition, to simplify the design of the device selected for the prototype, the thread can get into the cylindrical body by siteprovide, the outlet of which is located above the surface of the powder dye at rest, as in the claimed invention.

The invention consists in the following: when using powder the new ways of dyeing there is a significant saving of water resources. The proposed device provides dyeing yarn without the use of dye solution, the use of a minimum amount of water reduces the amount of hydrolyzed dye, which ensures a high degree of fixation of the dye on the fiber, which leads to the minimum cost of water for washing dyed yarn. In addition, to provide an even and regular dyeing of yarns and threads.

The technical result is to simplify the process of dyeing yarn, increasing the degree of fixation of the dye on the fiber, increasing rowmote staining.

This technical result is achieved by the fact that the known device for dyeing cotton yarn and threads powder dyes in a mixture with hydrotropism substances comprises a cylindrical housing with a dye bath, elastic cuff.

The peculiarity lies in the fact that the cylindrical body has an outlet port siteprovide located above the surface of the powder dye at rest.
