う欠点がある。A specific method for obtaining such a mixed yarn is to extrude two types of polymers one by one, immediately combine the two types of fiber bundles obtained, and then perform stretching, heat treatment, etc. method (spinning blending, method of drawing two types of fiber bundles with different drawing conditions and then spinning them into gold thread (drawn blending), or combining two types of undrawn yarns with different spinning speeds and then drawing or A common method is to perform the twisting process together.However,
All of these methods have the drawback that sufficient differences in physical properties cannot be obtained, or even if they can, the process is complicated.

要となり生産性の点で優れたものとは！えない。In order to obtain a sufficient difference in physical properties, it is necessary to combine two undrawn yarns, semi-drawn yarns, or drawn yarns with different elongations (for example, different spinning speeds or significantly different stretching conditions). However, in order to prepare two or more undrawn yarns, semi-drawn yarns, or drawn yarns with different elongations, two spinning machines with different spinning speeds are generally required. Or, if a drawing process and equipment are necessary to partially draw one fiber bundle, and if fiber bundles with different elongations are drawn with gold thread or false-twisted, these Two shelves (creels) are required to set the yarn. In this way, when using a combination of yarns with different elongations to create new, high-value-added materials, multiple spinning machines and creels are required, and operability becomes complicated. . What is better in terms of productivity because it requires a lot of effort and time? No.

性差を有する混繊糸を得ることは不可能である。Recently, since a drawn yarn can be obtained immediately by using the direct spinning drawing method, the direct spinning drawing method has attracted attention and is becoming widely used. A method of immediately obtaining a mixed fiber yarn with different shrinkage by using a spinneret, or a method of dividing the fiber bundle into two fiber bundles directly under the spinneret and changing the contact time between the two fiber bundles with the roller. Although methods for obtaining shrunk mixed fiber yarns have been proposed, it is impossible to obtain mixed fiber yarns with sufficient differences in physical properties using such methods.

ある。Means for Solving Problems〉 The present invention provides for the fiber bundle (A) and (Bl) formed by extruding a polymer from a spinning nozzle.
Al is taken up by a first roller, then taken up by a second roller that rotates at a speed higher than the surface speed of the first roller, and then wound into a winder. Processing is performed by a so-called direct spinning drawing method, and the fiber bundle fBl is transferred to the first roller. This is a method for producing a mixed fiber yarn, characterized in that the yarn is taken up by the second roller without being taken up, and the yarn is combined with a fiber bundle (Al) before or after the second roller, and then wound into the winder as a combined fiber bundle. .

ことか可能であることなどに着眼し、検討した結果から
得らｒしたのが本発明である。In conventional conventional spinning machines, even if there is a godet roller, the surface speed of the roller is almost the same as the winding speed, so it is difficult to obtain mixed fiber yarns with different draw ratios. On the other hand, in the direct spinning drawing device, the first roller speed (
Spinning speed and second roller speed (stretching speed ÷ winding speed)
can be freely changed, and if the yarn is directly guided to the second roller without using the first roller and taken up by the first roller, the yarn can be spun at a high speed that is different from the spinning speed of the first roller. can be collected,
In addition, we focused on the fact that it is possible to collect two types of drawn yarn with different draw ratios by installing two No. 1 four-layers and adopting different surface speeds. This is what the present invention has accomplished.
本発明方法の一例を次に図によって説明する。An example of the method of the invention will now be explained with reference to the figures.

縮や伸度の異なる混繊糸が得ら几ることとなる。The fiber bundle (Al) is discharged from the spinneret 1, applied with an oil by the oiling device 3, and subjected to stretching heat treatment by the first roller 4 and second roller 5 (heat treatment is not essential). It is discharged from the spinneret 2 (of course, it may be a part of the spinneret 1), is applied with oil by an oiling device 3, passes through a free roller or a separately driven first roller 6, and reaches the second roller 5.
The fiber bundle (Al and FB+) is combined before or after the roller, and if necessary, passed through an interlace entangling device 7 and wound up by a winder 9. As a result, the resulting refined fiber bundle (A) can obtain physical properties similar to drawn yarn or semi-drawn yarn,
- 10,000 fiber bundle + B) has different physical properties and spinning speed 5 from tA)
A high-speed undrawn yarn can be obtained, and a mixed yarn with different shrinkage and elongation between Al and (B) can be obtained.

のが好ましい。In the method of the present invention, in order to obtain two types of fiber bundles with different physical properties, two sets of spinning nozzles are used.Although it can also be used for applications such as mixed fibers of different fineness, the fiber bundles spun from one nozzle are There is no problem in dividing the . However, since the draft drawing ratios are different, the spinnability or drawing properties become unstable. Therefore, in order to obtain stable spinning and drawing properties, two sets of spinnerets are used, and the combination of spinnerets that match the spinning and drawing conditions must be used. It is preferable to use

で得らｒした混繊糸をその後仮撚する場合は低伸度延伸
糸側を単繊度大とするのが好ましい。When producing a yarn with mixed fineness or a bulky textured yarn that utilizes the difference in elongation, it is customary to use a low count fiber bundle as the core yarn. In this case, it is preferable to set the low-temperature drawn yarn side, where the shrinkage is large, or, when the mixed fiber yarn obtained in the present invention is subsequently false-twisted, to set the low-elongation drawn yarn side to have a large single fineness.
本発明方法の最大の特徴点として、第１ローラーと第２
ローラーの速度を自由に選びそれを組合せることが可能
であり、ざらに両ローラーの熱セツト温度の変更も可能
であるという点を活用したことにある。The biggest feature of the method of the present invention is that the first roller and the second roller
This method takes advantage of the fact that it is possible to freely select and combine the speeds of the rollers, and it is also possible to roughly change the heat set temperature of both rollers.

ましい。The fiber bundle to be drawn can be obtained from a low-speed spinning yarn to an ultra-high-speed spinning yarn by changing the take-up speed of the first roller, and can be arbitrarily stretched by the second roller. Monkey. The temperature of the first roller is preferably in the range of 70 to 90°C, which is the temperature of the 10th roller, from the viewpoint of good stretching properties.As for the second roller, if the heat setting temperature of the second roller is too high, the stretching of the other roller will be affected. Since the fiber bundles that are not subjected to heat setting are also heat set, it is desirable that the 20th-Ra1 temperature be as close to room temperature as possible, except in special cases, and specifically, be below the secondary transition point temperature.
これらのことから、繊維束（Ａｌとしては比較的低伸度
領域と高収縮領域の延伸系が得易すく、高伸度領域や低
収縮領域の延伸糸は比較的得難い。For these reasons, it is easy to obtain a drawn fiber bundle (Al) in a relatively low elongation region and a high shrinkage region, and it is relatively difficult to obtain a drawn yarn in a high elongation region and a low shrinkage region.
−万、繊維束（Ｂ）は、通常は延伸を行なわずに直接第
２ｐ−ローに巻取るのであるから、比較旧低速の未延伸
糸は得難く、中高速から超高速甲での未延伸糸を得易す
いこととなり、したがって中伸度領域で且つ高収縮領域
から低収縮領域までの未延伸糸が得ら几ることとなる。- Since the fiber bundle (B) is normally wound directly onto the second p-row without drawing, it is difficult to obtain an undrawn yarn at a comparatively low speed, and an undrawn yarn at a medium to ultra-high speed A is difficult to obtain. It is easier to obtain a yarn, and therefore, it is easier to obtain an undrawn yarn in a medium elongation range and from a high shrinkage range to a low shrinkage range.
これら延伸糸と未延伸糸を種々組合せることにより、収
縮差や伸度差を有する混繊糸の製造か可能である。By various combinations of these drawn yarns and undrawn yarns, it is possible to produce mixed fiber yarns having different shrinkage and elongation differences.

餞などにより、糸ゆｒしや糸当りを防ぐことが出来る。The biggest operational difficulty of the method of the present invention is that the fiber bundles Δ and B
The method of guiding the yarn, the number of times it is wound around the roller, and the number of times it is wound. In particular, only the fiber bundle is wound several turns in succession on the first roller, and when the yarn is doubled on the second roller, it is necessary to wind it again several turns in succession, so it is necessary to add a splitting guide to the roller bend, etc. This can prevent yarn sway and yarn hit.

ましい。As the polymer used in the method of the present invention, polyester, ie, a polyester polymer containing ethylene terephthalate units as a main component, is preferable from the viewpoint of heat setting properties and use in clothing.
