[Technical Field] The present invention relates to an improvement in the manufacturing method of composite interlaced yarn. [Prior art] Methods for producing composite entangled yarns consisting of two or more multifilaments using an air entanglement treatment method can be broadly classified into two types, one of which is to actively slacken the yarns. The other method involves intertwining the fibers without intertwining them to produce a non-bulky composite interwoven yarn, and the other method involves intertwining the fibers while substantially oversupplying the fibers, resulting in appearance characteristics such as loops and sometimes fluff. Many methods have been proposed for producing so-called spunlike yarns. Regarding the former, it is almost flat in appearance and has no characteristics, and is often handled as a single yarn as a means of imparting convergence, and in many cases it is widely used in the spinning or stretching and twisting stages. Although it has been used partly as a means of compounding, there are few examples of its use in post-processing after spinning. This is due to the lack of yarn morphology characteristics as mentioned above, and in addition, when used in post-processing, the supplied raw yarn is often essentially twisted, which makes it difficult to obtain sufficient and uniform entanglement. It seems to be for a reason. However, in the recent development of a wide variety of differentiated materials, there is a demand for a wide variety of products in small quantities, and direct compounding at the time of spinning or stretching or twisting does not allow for the so-called small rotation, and the momentum and post-processing are not effective. Increasingly, there is a demand for multiplexing. [Object of the Invention] Based on these backgrounds, the present invention provides a method for producing a composite interlaced yarn using substantially twisted raw yarn. [Structure of the Invention] That is, the present invention provides a method for manufacturing a non-bulky composite interlaced yarn by aligning two or more multifilaments having yarn twists in the same direction and performing an air entanglement process. A method for producing a composite interlaced yarn, characterized in that the arranged multifilaments are subjected to air entanglement treatment while being twisted in a direction opposite to the original yarn twisting direction of the multifilaments. The present invention will be explained in more detail with reference to the drawings below. Fig. 1 shows a method for manufacturing a composite intertwined yarn in a commonly performed post-processing process. pulled together,
Yarn is fed from a feed roller 4, and the feeding rate is adjusted by a delivery roller 6 to such an extent that the yarn does not become substantially slack, and in the meantime, a compounding process is performed by an air entanglement treatment device. In this case, the supplied multifilaments are each bundled by yarn twisting and oil agent, etc. In particular, the binding by twisting is strong and reliable even with a small number of twists, so the two multifilaments are subjected to air entanglement treatment. However, it is difficult for the constituent filaments to become entangled with each other, and the yarn tends to become asymmetrically entangled, with many parts where two multifilaments are separated. The present inventors focused on the convergence of two multifilaments during such air entanglement treatment, and arrived at the present invention. FIG. 2 shows an example of this, and shows an example using a down twister machine, in which an air entanglement treatment device 5 is arranged between a feed roller 4 and a burring guide 8, and a winding section 9
By performing the air entanglement treatment while twisting the yarn in the opposite direction to the original yarn twisting, it is possible to obtain a relatively uniform entangled yarn in which the constituent filaments of the two aligned multifilaments are intertwined with each other. in this case,
It is important to eliminate the torque caused by yarn twisting of each multifilament in order to improve the opening performance of each multifilament. This is done smoothly, and mutual entanglement is performed evenly. It is natural that the cohesiveness of two aligned multifilaments is improved by twisting, and together with these additional effects, it becomes possible to manufacture a composite interlaced yarn with uniform entanglement and good cohesiveness. However, if too much twisting in the opposite direction is applied, the twisting effect due to the twisting increases, making it difficult to perform the opening effect due to air entangling treatment, and the mixing and entangling effect cannot be achieved. Ordinary multifilament yarn twist is about 20T/M or less, and at most about 60 to 80T/M or less, so the reverse direction flammability during air entanglement treatment is
80T/M or less is desirable. In addition, in Fig. 2, when the two multifilaments are subjected to twisting in the same direction as the original yarn twisting, each of the two multifilaments is further subjected to strain in the same direction as the original yarn twisting, and the torque increases. It is more difficult to open the multifilaments, and the two multifilaments are highly separable, making it difficult to form a good composite interlaced yarn. FIG. 3 shows another embodiment of the present invention, in which a temporary combustion device 10 is arranged between the air entanglement treatment device 5 and the delivery roller 6. By placing the multifilament to be subjected to the air entanglement treatment using this twisting device 10 in the direction opposite to the twisting direction of the original yarn, a uniformly entangled yarn can be obtained. Become. As for the false twisting device used in this case, it is important to have low resistance when the yarn passes through in order to maintain the entanglement once it has been applied. desirable. It goes without saying that the number of multifilaments to be supplied is not limited to two, but may be three or more. Example 1 Triacetate multifilament B150d/
40f, 8T/M (S) and polyester multifilament SD50d/24f, 9T/M (S) were heated at a spindle rotation speed of 5000 r.pm using the apparatus shown in Figure 2.
Others were treated under the conditions shown in Table 1. The hook drop value (abbreviated as HD value) and the uniformity of entanglement of the obtained yarn are also shown in the same table.

[Table] From Table 1, despite the same number of additional twists of 50T/M, the Z twist setting is clearly better in terms of uniformity of entanglement, and the Z twist setting also has a better entanglement level. It can be seen that more detailed confounding can be obtained. Example 2 Triacetate multifilament B150d/
40f, 8T/M (S) and polyester multifilament SD50d/24f, 9T/M (S) were wound at a yarn feeding speed of 100 m using the device shown in Figure 2 (however, No. 14 was the device shown in Figure 4). Take-up tension 14-15g, injection air pressure 3.0
The processing was performed under the conditions shown in Table 2 for Kg/cm 2 , number of twists, and direction of twist. The HD value and entangling uniformity of the obtained yarns are also shown in the same table.
