The invention relates to the textile industry, namely, to impregnate yarn and yarn in artificial, synthetic, and natural fiber and yarn processing plants.

The purpose of the invention is to improve the quality of impregnation due to uniform application of the treatment solution,

The drawing shows the implementation of the proposed method.

The impregnation method is carried out as follows.

In the bath 1, having an inlet nozzle 2 for supplying the treatment solution and an outlet nozzle 3 for draining the solution, a cassette 4 made of filter material, for example, a mesh, is installed. In the cassette 4 in the processing solution and above the level of the solution are placed layers of contacting between themselves granules 5, in the form of balls. Diameter of each facet

ly 5 exceeds the diameter of the filament 6 in 2-7 times. After the bath 1 is filled with the treatment solution to the level of the outlet nozzle 3, the bath 1, together with the cassette 4, is lowered down

The thread 6 is unwound from the package, and through the guide eye 8, the eye 9 of the thread guide 10 and the guide eye 11 are tucked under the cover 12 of the bath 1. The cover 12 is fixed immobile on the rod 7.

The thread guide 10 is mounted on the lid 12 with the possibility of adjusting the immersion height of its refueling eye. Then, by raising the bath 1 with the cassette 4 along the stem 7, the thread 6 is brought into contact with the treatment solution and the balls 5.

The treatment solution is in the bath at the level of the branch nozzle and, penetrating through the filter walls, fills the cassette 4 to the same level.

When moving in the bath, the thread goes through three sections: in the first section, the thread goes through a layer of balls located above the level of the solution, where it is partially cleaned about the fluff, the fluffs and other impurities. In the second section, the thread passes through a layer of balls located in the treatment solution. Due to the interaction of the balls with the thread, with their pressure on the thread, in this zone

impregnation occurs deeper penetration of the processing solution into the structure of the thread. In the third section, the thread impregnated with the treatment solution passes through a layer of balls arranged at the level of the solution, while the balls put pressure on the thread and remove excess processing solution from it. Clearly removed excess of the solution from the surface of the thread flows over the surface of the balls and the free space between them through the filter walls of the cartridge 4 into the bath 1 for reuse.

The uniformity of the application of the treatment of the diluted solution (second and third, sections) is increased due to the repeated action of the balls on the thread over a large segment of the path. The inclined spin working zone (section III) provides optimal conditions for removing excess treatment solution from the thread and withdrawing it from the zone of removal 1a. When the vertical working area is pressed (the third section), the removal of excess treatment solution with them and its removal are the same, which does not provide the specified spin, i.e. remove excess treatment solution. With a horizontal pressing area (third section), there is a separation of areas for removing processing solution from the thread and withdrawing it from the pressing zone, however, this significantly increases the spin area and increases the tension of the thread, which leads to its breakage.

The choice of the ratio of the diameter of the balls to the diameter of the processed yarn, equal to 2-7, is set as follows; To remove the excess of the treated solution evenly over the entire surface of the thread, it is necessary to ensure that the balls touch the thread along its perimeter 6 at several points, as

possible ball entrainment with thread, especially

at high speed of movement of the thread, which degrades its quality (according to the results of the experiment),

To ensure a stable mode of implementation of the method, a prerequisite is to maintain the ratio of the solution level in the cassette and, accordingly, reduce the spin zone (i.e., a ratio of more than 1: 5) during the impregnation thread takes away an excess amount of treatment agent spinning zone. When the level of the treated solution in the cassette is lowered (i.e., the ratio is less than 1: 7), the thread is not uniformly impregnated due to the insufficient duration of the contact of the thread with the treatment solution. .

The application of the method makes it possible to improve the quality of the threads and the uniformity of application of the treatment solution to them, for example, the dye-adhesive composition in the production of glued threads due to the repeated impact on the thread of the balls both in the impregnation zone and in the spinning zone. Since the processing solution is constantly

is removed from the spin zone, the spin zone performance does not change with time, and the balls do not wear out during operation.

Claims (2)

1. A method of impregnating a textile material, preferably a yarn, which consists in placing the contacting granules in the form of balls into the treatment solution, and passing the thread through the treatment solution for impregnating it, characterized in that In order to improve the quality of impregnation due to a uniform solution, a layer of dry granules contacting each other is additionally placed above the level of the solution, and the thread after impregnation is pressed by oblique drawing the granules, the diameter of each granule being 2-7 times the diameter of the thread. 2. A method according to claim 1, characterized in that the thread is cleaned prior to impregnation by passing it through a layer of dry beads. WITH-)
