The present invention relates to a method for producing a polyester blend yarn, and more specifically, a method for producing a polyester blend yarn, in which two or more groups of fibers with different denier fibers are processed by hot water treatment, such that the thick denier component becomes a high shrinkage component and the fine denier component becomes a low shrinkage component. This article relates to a method for producing a polyester blend yarn that is composed of filaments, has a significantly improved degree of mixing of thick denier components and fine denier components, and has a great norky feel. With the diversification, luxury, and individualization of clothing, research is being actively conducted to incorporate the desirable texture of natural fibers into synthetic fibers as well. In natural fibers used for clothing, such as wool and silk, the variation in individual ready-to-woven kasuri patterns is greater than that in synthetic fibers. However, rather than being a deficiency, this variation can be called an advantage. It is clearly effective. Therefore, even when it comes to synthetic fibers, there is a conscious difference in denier between the fibers. Difference in shrinkage, I, stacking, mixed multifilament 1
1 Te has been published by PR company I since 316 J. -+(1, such as i'17. How to spin P yarn and 17 V', spin multifilaments with different medium Ql t denier and physical property values 1' separately) Inquiry about the interlacing at the edge, drawing process, and temporary mixing process.
In order to spin each multifilament J1 separately, spinning 11. ' 41 'Iff Mf de=-le,
Material ec (f1'+) It is possible to change the texture, and it is possible to obtain a very rich cotton material with a wide variety of textures. city,
In history, the spinning j. Not only can it not be made higher,
In order to improve the degree of blending, it is necessary to add interlacing, and there is a drawback that the 1st stroke of J construction becomes extremely high. In addition, since the thread path of Wei (itl after Cao, one creel stand &, 117, etc.) is also difficult, it is not good in terms of workability. Ta. Of course, in order to eliminate the above-mentioned drawbacks, methods have also been proposed in which the fibers are spun during spinning. However, the mainstream method of these 11 is to spin different filaments to JP printing 1# denier, physical properties A), or from the first spinneret, and in this case, the equipment Due to the relatively low spinning speed of l- to 9μ, a stretching process is additionally required. In addition, the simplification of the equipment in 10n1゛, as it is, led to a decrease in work efficiency and was not convenient.Therefore, in an attempt to improve this method, high-speed spinning, for example, a spinning speed of 3500 m7xrrn, was adopted. A method for manufacturing the above-mentioned blended yarn has been proposed.In other words, the yarn is oriented and crystallized at high speed spinning, but the thick denier component and the fine denier component are mixed. When denier component -2 is extruded from the same spindle and spun at 350 (I nt /j+"), the fine denier component undergoes more oriented crystallization than the thick denier component, so the fine denier component has a low yield F(
In this method, the large denier component is the high shrinkage component, and this difference is taken as the shrinkage difference. 1. However, in this case, there was a big gap in terms of production.In other words, this method spins the components of ηI V denier simultaneously from the same gold, and From the 7-way side,
+tt between thick denier component and I'll denier component
##It is necessary to make the fat denier difference sufficiently large. However, Gun 7jA! @; When the Tenney A difference is increased,
Because the cooling rates of the thick denier component and the fine denier component are different, the thick denier component that has not been completely cooled and solidified and the fine denier component that has been completely cooled and solidified are spinning 1'' under the entire surface I.
Q Due to contact within Orrn, fuzz yarn breakage occurred frequently and yarn spinning-1
= A fatal bolt p1 occurs. As a method to solve this problem, various studies have been conducted on the cooling force conditions of the yarn, but no sufficient effect has been obtained, and in the present world, it is necessary to divide the denier component into the thick denier component and the thick denier component. For example, as shown in Figure 1 ← Spinning 1-1 Only the denier component is spun from the right half of the gold 1
For the -1 and left sitting portions, methods of producing only the thick denier component by π1 are mainly being promoted. In this case, the fine denier component and the large denier component are clearly separated and emitted from the RFI even after spinning from the spinneret, so even if the shrinkage rate difference between the image components is large, the entanglement of the white component was insufficient, and the bulkiness was insufficient. As a method to solve this problem, a 4H method has been proposed in which white components are entangled with each other by interlacing. However, when applying interlace during winding, the winding speed is 3500 m/M or more, so sufficient interlacing cannot be achieved. When interlace is applied to yarn, it is not suitable in terms of quality because dyeing odor "t!":T occurs due to interlacing irregularities, and also from the point of view of the cost of interlacing as the t:l manufacturing process increases. Thus, the degree of mixing between the components can be further improved just by spinning and winding.It was hoped that a technology for manufacturing a mixed yarn with a higher bulkiness could be established.Therefore, the present invention As a result of intensive study on this point, the present invention has been completed.That is, the gist of the present invention is that a large denier filament group and a fine denier filament group have the same base, end, and Dispersed Owabimapuko is spun into a well-mixed arrangement by packing in a concentric circle, and at that time, no

[3] The spinning draft of the large diameter filament group is set to 350 or more, and the spinning draft is set to 350 or more. According to the invention of A1, it is possible to obtain a blended uI yarn with a sufficiently large shrinkage difference between the thick denier component and the fine denier component, and the blending of both components is extremely good, so it does not feel bulky compared to conventional blended yarns. The one that has been changed to a large cloth. Furthermore, as mentioned above, there is very little adhesion and yarn breakage during spinning, so the productivity is extremely high. In addition, since the present invention can be rolled up at high speed, it has excellent strength and elongation, which is essential (
7. It is not necessary to stretch the yarn as much as in the second drawing.
1 t It is also possible to use it for ships II. As described above, according to the method of the present invention, the mixing of the thick denier component and the fine denier component is greatly improved compared to the conventional mixed yarn, and the bulky textured mixed yarn can be produced without problems during spinning. It is a product that can be manufactured using a warm yarn that can be used for knitting fabrics using just the spinner's culm, and its industrial significance is extremely large. The present invention will be explained in more detail. In the present invention, the target polyester is one in which 85 moles or more of the repeating unit is essentially composed of ethylenetete and phthalate, and is copolymerized with additives for purposes such as matting, improving dyeability, and preventing static electricity. It may be included as a combination or blend. The intrinsic viscosity of the polyester represented by polyethylene terephthalate (measured in ochlorophenol at 35°C) is preferably from 0.45 to 1.20, particularly from 0.50 to
, oO is preferable. When the intrinsic viscosity is less than 0.45, the strength level of the resulting clamping frame is undesirably low. Also, the authority viscosity is 1.20, which is 11. ! i i;i:

One piece of fiber of 0 de/36 r+z was taken. Incidentally, during winding, the spinning speed was variously changed. The thread truts for each sentence during spinning are as shown in Table - ■, and the ? of each component? Table 1 shows the Ie water unilateral bending rate, the difference in shrinkage rate between thick denier and thin denier, and mechanical properties. Cloth-I Shrinkage rate In the above example, the maximum Kishi fiber deninyl is 5.0 + l.
e. Although the smallest one is 1.9 de, which is a very large difference in denier, the spinning draft of the thick denier component is extremely large, so there is almost no yarn fluctuation of the thick denier component, and there is little adhesion fuzz. There were also fewer thread breaks. Samples A1 to A5 were knitted in a tube and dyed with a disperse dye. The staining conditions in this case are as follows.

N (: The difference in shrinkage is 5 There is no fullness, no lumpy feeling at all. 0. Evaluation was made by comprehensively considering the mechanical properties and texture. In this way, the difference in shrinkage between the thick denier component and the fine denier component is 5%. As described above, when the thick denier component and the thick denier are arranged concentrically, the blended yarn with a large bulky feel is produced, especially at a spinning speed of 4300 to 4700 m/
In the immediate area, the shrinkage difference was 10 inches or more, the bulky feeling was large, and the mechanical properties were also excellent, as it did not require a stretching process.
