Description

one

The invention relates to textile finishing and can be used to obtain patterns on textile materials.

A method and a device for polychromatic dyeing of fabrics is known, which ensures the spreading of thin streams of dye solutions coming from several tanks through separate pipelines to the mover from the web and containing squeezing rolls, between which the fabric passes after applying dye solutions 11 to hee.

It is also known a device for polychromatic dyeing of fabrics, in which, along with nozzles for spraying dye solutions, there are nozzles for supplying compressed air, and jets of compressed air act on the jets of dye solutions in such a way that the air jet deflects the stream of dye solution from its original direction so that the dye solution either gets onto the moving textile fabric, or returns to the circulation system according to a predetermined program in accordance with the design unkom cloth 2.

A device is known that contains a grooved plate inclined at an angle of 45 with respect to a horizontally moving material to be painted, to which the plate abuts with its lower edge. A swiveling beam is installed above the plate with nozzles fixed on it, to each of which a separate hose is supplied with a dye solution from the corresponding container. At a distance from the inclined plate in the direction of movement of the material, a pair of squeeze rolls are installed. Passing under the lower edge of the inclined plate, the material is impregnated with the dye solutions flowing down the plate, forming on it a flow line. Pass material through the sting

The 20 squeeze rolls promote the mixing of dye solutions that impregnate the material at the boundaries between the strips, create smooth transitions between the strips, and also ensure the complete penetration of the dye solution into the material and the same intensity of color on its front and back sides.

by filing the material with a composite solution pre-mixed with compressed air.

It is also known a device for carrying out a method of polychromatic dyeing of a textile material, which contains containers for a dye solution installed above the plane of displacement of the textile material, an inclined plate arranged under them, means for feeding the dye solution from the container to the plate and a pipe mounted parallel to the latter with reciprocible longitudinal movement. nozzles connected to the compressed air supply system 4.

A disadvantage of the known solutions is the limited possibility of obtaining a variety of patterned patterns having the character of moire, lace, marble effect.

The goal of the solution is to expand technological capabilities by increasing the range of design.

The goal is achieved by the method of polychromatic dyeing a textile material by supplying a dye solution previously compressed with compressed air to the material, after supplying the dye solution to the material on the latter is exposed to jets of compressed air to agitate the dye solution of non-adsorbed textile material. under pressure in the range of 0.3-0.7 kg / cm.

Moreover, a device for polychromatic dyeing of a textile material, containing a container for a dyeing solution installed by a plane of the textile material, an inclined plate positioned under them, means for feeding the dyeing solution from the container to the plate and a pipe mounted parallel to the latter with the possibility of reciprocal longitudinal movement the nozzles associated with the compressed air supply system additionally have located Another material is the slot nozzles connected to the compressed air supply system through flexible nozzles, and the means for supplying the dye solution from the container to the plate consists of a tube installed transversely to the pipe with nozzles attached to it connected to the corresponding capacity using a flexible pipe. nozzles may be located transversely or longitudinally or at an angle to the plane of movement of the material at a distance of less than 20 mm from the lower edge of the inclined plate.

The method is carried out as follows.

The dye solution from the container is fed through a pipe with nozzles to an inclined plate, where it is mixed with jets of compressed air. Each nozzle has its own solenoid valve i for remote control of a given on / off sequence when making the desired pattern. Dye solution mixed with compressed air flows from the inclined plate to the textile material. The non-adsorbed textile dye solution is exposed to compressed air to mix the dye solution and create a specific pattern. Compressed air is supplied to the material: a rial under a pressure of 0.30, 7 kg / cm, depending on what kind of mixing or splashing of dye solutions is necessary. After the pattern is formed, the material is dried and further processed according to the technology adopted.

FIG. 1 schematically shows the proposed device; in fig. 2 version of the arrangement of the slit nozzles; in fig. 3 is a view A of FIG. 2; in fig. 4 is a view of B in FIG. 2

The device contains containers for dyeing solution 1 installed above the plane of movement of the textile material 2. Under the containers 1 there is a plate 3 with an inclination relative to the plane of movement of the textile material 2. To supply the dyeing solution from the container 1 to the plate 3 there is a tool made in the form of a pipe 4 with nozzles 5 attached to it. Each pipe is connected via a flexible pipe b with a corresponding container. In parallel, the plate 3 is mounted with the possibility of reciprocal longitudinal movement of the pipe 7, having nozzles 8 connected by a flexible pipe 9 to the system 10 of the compressed air supply. In parallel with the plane of movement of the material 2, slotted nozzles 11 are placed on the pipe 12 and connected by means of a flexible pipe 13 to a source of compressed air 10.

Slotted nozzles 11 can be located transversely or longitudinally (Fig. 3) of the plane of movement of the material 2. Sometimes the slotted nozzles can be located at an acute angle relative to the plane of alternation of the material (Figs. 4 and 5). The angle of the nozzles can be adjusted. The nozzles 8 for supplying compressed air to the inclined plate 3 are located at a distance of less than 20 mm.

65 from its lower edge. The device also contains a pair of press shafts 14 located at the output of the textile material 2 from the treatment area. The pipes 4 and 12, as well as the pipe 7, are also installed with the possibility of reciprocating motion (their drive is not shown in the drawing). The width of the slot nozzles 8 and 11 is 1 mm, the slot length is 30 mm. The diameter of the outlet of each of the nozzles 5 for feeding the dye solution is 0.8 mm. The device works as follows. From tanks 1, through the hoses b to form X1M 5, dye solutions are supplied, which after exiting the nozzles 5 fall onto the inclined plate 3 and flow down it onto the continuously moving material 2, Flows of the dye solutions flowing down the plate 3 are subjected to air streams flowing out of the plate 3 nozzles 8 to which compressed air with a pressure of 0.3-0.7 kg / cm is supplied through flexible pipes 9. Under the action of compressed air, with which the plate 3 is blown out of the nozzles 8, the flowing streamers of the dye brittle liquids are crushed and mixed together before they get onto the material 2. As a result of this crushing and mixing the boundary between adjacent dye blasts appear to be blurred, which makes it possible to obtain a variety of rotating patterned patterns that have the character of moire, lace, marble effect, etc. Due to the installation of a second row of air nozzles 11, connected with flexible pipe 13 to the compressed air supply system, which blows material 2 directly after applying dye solutions that flow over plate 3, an additional color effect is achieved due to mixing of dye drops that fell on fabric, but have not yet had time to absorb it. After applying the dye solutions on the material 2, the sting of the squeeze rolls 14 passes, by means of which excess solutions are removed. In addition, the squeeze rolls 14 contribute to the penetration of the solution - the entire thickness of the fabric and the creation of the same intensity of color on her face and on the wrong side. After passing the squeeze rolls, the fabric is dried and set at 140–150 ° C and washed. The application of the invention expands the possibility of obtaining various patterns and color designs of textile material at low cost (compared to printing) for equipment and its operation.
