    The invention relates to synthetic yarn and yarn-like structures. …<??>Separate strands (1, 2, 3) of thermoplastic material are treated so that at least one (2, 3) has a shrinkage ratio higher than normal at an elevated temperature. The strands are intermingled in a gas stream with formation of loops (21) on the strands, then heated to cause them to shrink differentially while being held to a predetermined length, then cooled while being held until shrinkage ceases. Apparatus for performing the method includes yarn drawing means (7, 8, 9) intermingling means comprising a jet device (10) incorporating intersecting passages (11, 12) for the strands and for a gas under pressure, feeding means (4, 5, 6) and heating (16) and cooling (19) means for the intermingled yarn downstream from the jet device, also means (16, 17 and 17, 18) for holding the intermingled yarn to a predetermined length while it is being heated and cooled. …<??>The yarn produced is flexible, of uniform cross section and shows no tendency for the strands to separate.

    The invention relates to the textile industry, in particular to the manufacture of synthetic yarn.
    The purpose of the invention is to increase the processing efficiency.
    Figure 1 is a diagram of the installation for the implementation of the proposed method; figure 2 shows the yarn after the jet means; on 4 mg. Z - ready, 10, obtained by the proposed method.
    The method involves drawing at least one bundle of filaments of a thermoplastic material, which are then fed forward at various feed rates, then mixed by means of a turbulent fluid flow. The resulting mixed yarn is heated to shrink and cool. The heating of the mixed yarn 20 is conducted to 180 ° C, and the cooling to room temperature. When heated and cooled, the yarn is held at a predetermined length.
    The method is carried out in the following way.
    The different bundles of yarns 1-3 (Fig. 1) are fed by feed rollers 4-6 after stretching means 7-9. The rollers 4-6 threads are fed at different feed speeds, and the speed of one of them, for example beam 1, is lower than the speed of the others. The beams are then fed to a mixing device; 10, containing a jet device 35 with a channel 11 for the bundles of threads and channels 12 for supplying a turbulent flow of tea fluid. The position of the channel 11 can be changed in the body of the tool 10, which provides suction. Properties to this means for pulling the ends of the bundles of threads with tension.
    The means 0 has a mixing zone 13, where, under the action of a turbulent fluid flow, the mixes beams and the mixed yields are obtained 14. Behind the means 10 there is a barrier in the form of a roller 15 that can move from the body of the means 10 and in the direction and in it. Yes, a 50 nee mixed yarn 14 is supplied to the heating roller 6, the passage of the separating roller 17, and the final pair of rollers 18 is output from the structure. Before the height of the pair 55
    the mixed thread passes through the cooling zone 19. Here, yarn 20 is cooled to room temperature, at which its contraction cannot occur. The outlet rollers 18, when operating the unit, keep a portion of the yarn located between the rollers 17 and 18 for shrinking. The process is heated on roller 18 to 180 ° C.
    When mixing bundles of yarns on the mixed right, loops 21 are formed.
    The speed of the mixed yarn when it exits the tool 10 is less than the speed with which it enters it. On rollers 17 and 18, the length is maintained at a predetermined specific length. This length is maintained during the heating and cooling operation. Mixed tufts 1-3 are shrunk according to their shrinkage properties and, being held at a predetermined length, they are mixed due to the resulting tensing forces arising in the nickname as a result of the tendency of the threads to shrink during shrinkage. As a consequence, the loops 22 are compressed, taking the tuft-like shape of the protrusion 22. Passing the discharge rollers 18, the yarn 20 is in a steady state. With shrinkage, the bundle that shrinks with the least degree of shrinkage, for example 1, tends to become central. Other bundles are located around it.

    Invention Formula
    A method of producing untwisted yarn from at least two separate bundles of yarns of thermoplastic material, in which at least one bundle of yarns is pulled, feeding the bundles forward at different speeds, then mixing them with a turbulent fluid flow effect, heating the mixed yarn to shrink and cooled, characterized in that, in order to increase the processing efficiency, the mixed yarn is heated to 180 ° C, and cooled to room temperature, and when heated and cooled, the yarn is kept Ivayut at a given length.
