    The invention relates to the production of chemical threads.
    The purpose of the invention is to improve the quality by increasing the strength, reducing the residual shrinkage and decreasing the tension during shrinking.
    The drawing is a diagram of the proposed method.
    Polyester yarns 1 are straightened out of a melt of polyethylene terephthalate with high relative viscosity using a spinning nozzle 2, and then sent to a stretch tube 3. As the tube passes, 3 strands 1 turn and become a multi-yarn yarn 4, which is fed Then the yarn 4 passes through the heater 6, and then into the stretching section, where the rollers 8 and 7 are mounted, rotate at the same speed, exceeding the speed The rotational speed of the feed roller 5. After passing through the rollers 8 and 7, the yarn takes the form of an elongated yarn 9. The rollers 7 and 8 are placed in a heated section 10. From the window of the roller 7, the yarn 9 undergoes relaxation and takes the form of yarn 11 Yarn 11 is then subjected to weaving, passing it through the weaving of the die plate 12, where the weaving of the components of the yarn is produced by a stream of heated air. Leave
    spinneret 12, yarn takes the form of interwoven yarn 13 and enters the winding roller 14 ahead of time. Winding is carried out at a speed of at least 1650 m / min. The yarn is subjected to finishing (not shown in the diagram), and usually the finishing operations are carried out with the yarn 4 that has not passed and with the yarn 9 that has passed through in the section between the heater 6 and section 10.
    String 13 as it passes to the winding roller 14 is subjected to heat. To do this, use heated air: with in the interlacing die 12 to prevent cooling of the yarn 11.
    Thus, during relaxation, weaving and winding, the yarn temperature is maintained within certain limits. It was established experimentally that the heating temperature is maintained within 90 - 260 ° C, after

    After stretching, the temperature is preferably maintained between 200 and 260 ° C. The optimum temperature is 235–255 ° C, while I spin the chamber into an isolated volume. The degree of feed ahead of the winding corresponds to 10-15%.
    The proposed method is used to manufacture polyester textile yarn with lower relative viscosity, which contributes to obtaining yarn of higher quality, with increased strength with lower levels of sufficient shrinkage and a decrease in tension during shrinkage.
