[Detailed description of the invention]

INDUSTRIAL APPLICATION FIELD OF THE INVENTION The present invention relates to a method for manufacturing fancy yarns having a stable triple spiral section of a long length according to requirements. (Prior Art) Currently, fancy yarns are produced by simultaneously false twisting and crimping at least two types of filaments, one filament being relatively straight and arranged in the core, and the other filament being Fancy yarn, which is wound around a filament in the core by forming at least a single spiral part and a triple spiral part alternately, is popular in women's knitted fabrics because of its smooth texture due to its uneven surface. It is used. (Problems to be Solved by the Invention) However, such fancy yarns generally have a short triple spiral portion. This is because the supply distance has to be shortened due to the machine. In recent years, due to the trend of fashion, fancy yarns with long triple spiral parts have become preferred. Therefore, it is an object of the present invention to provide a method for producing fancy yarn having a long slab of triple spiral portion in accordance with market demands. (Means for Solving the Problems) The present invention takes the following measures to solve the problems. That is, in the present invention, when at least one filament yarn is false-twisted, other yarns are supplied to the twisted region to alternately form triple spiral portions and single spiral portions, and the at least one
A method for producing a fancy yarn by winding a regular filament yarn through a heat-setting zone, in which the at least one filament yarn is passively fed through a tension adjustment device, while the other yarn is fed passively through a tension adjustment device; from the running line of said at least one filament yarn from the front of the device by means of actively driven rollers 20 having guides 16, 21 for smoothing the tension back and forth.
This is a method for producing fancy yarn, characterized in that the filament yarn is supplied to and wound around the at least one filament yarn from a guide 23 spaced apart from 300 to 1000 mm. The present invention will be explained below with reference to the drawings. Figures 1 and 2 are related to a conventional device for manufacturing fancy yarn, and Figure 1 is a side view and Figure 2 is a side view.
Figure A is a partially omitted schematic perspective view, and Figure 2B is a schematic front view. In Figure 1, the filament yarn Yo
is unwound from the pirn P, passes through the guide 1, is supplied to the actively driven feed roller 2, and is heated by the heater 6.
It is then sent to a false twisting device 7. At this time, other threads
Y ₁ is actively fed by the feed roller 3 and passes through the hole 5 of the guide 4 to the filament yarn Y ₀
While traversing, it wraps around itself in triple, single, and triple layers. The filament yarn Y ₀ and the yarn Y ₁ are combined and passed through a false twisting device 7 and pulled out by a delivery roller 8, and then passed through a heater 9 and a second delivery roller 10 to be transferred to a winding drum 11 as fancy yarn Y. It is then wound around a winding core 12 to form a package 13. Here, as is clear from FIGS. 1 and 2, the yarn Y ₁ is fed in the side direction of the device through the hole 5 of the guide 4 and wraps around the filament yarn Y ₀ while traversing. However,
A large number of weights are arranged side by side in the lateral direction, and therefore the vertical distance from the hole 5 to the filament yarn _Y0 , that is, the supply distance l (see FIG. 2B) has to be limited. Because the supply distance l was short, the long slabs required by the market could not be manufactured. On the other hand, in the present invention, the supply distance l has been successfully increased, and therefore a long triple spiral portion can be stably obtained. That is, FIG. 3A is a schematic perspective view of the device used in the present invention, and FIG. _3B is a schematic side view. It is then passively supplied and sent to the heater 6 through the guide 15. The magnetic tensor in this case is a type of thread tension adjustment device that adjusts the tension by creating rotational resistance of the roller depending on the strength of the magnet. The reason why the passive supply method using the tension adjustment device is adopted is to eliminate mechanical constraints such as vibration and to widen the space above the heater 6. Active feeding methods using rollers cannot absorb tension fluctuations such as vibrations, so in order to stably wind the yarn Y ₁ , the upper space, that is, the distance between the feed roller 2 and the heater 6, is unnecessarily widened. It cannot be done. On the other hand, the yarn Y ₁ has guides 16, 17, 18,
19, positive drive roller 20, guides 21, 22,
23 and is wound around the filament thread Y ₀ while traversing up and down. Here, the supply distance l is
It needs to be 300-1000mm. If l is less than 300 mm, the characteristics of the so-called long slab will be lost, and if l exceeds 1000 mm, problems will arise in terms of operation and space. Here, the yarn Y ₁ is passed through the guide 23 by an active drive roller 20 having guides 16 and 21 that smoothes the tension back and forth, and then the third
As shown in figure A, insert the filament yarn Y ₀ from the front of the device.
The method of supplying it to the traverse and winding it is
This is to fully utilize the space above the heater 6. That is, the actively driven roller 20 has guides 16 and 21 that smooth the tension back and forth by utilizing the space.
This is to form a stable triple spiral portion when the yarn Y ₁ is wound around the multifilament yarn Y ₀ with a large distance l. When the device is not fed from the front, the distance l cannot be made long, as already mentioned in the explanation of FIG. Simply increasing l from the front of the device does not allow yarn Y ₁ to be wound around multifilament yarn Y ₀ to form a stable triple spiral portion. Furthermore, the filament yarn referred to in the present invention refers to multifilament yarn or monofilament yarn,
At least one filament thread is used.
Yarn also means multifilament yarn, monofilament yarn, or crimped yarn, and at least one yarn is used. In addition, it is preferable that the fineness of the filament of the filament yarn serving as the core yarn is greater than or equal to the fineness of the single fibers of the yarn serving as the entangled yarn, from the viewpoint of stability of the obtained fancy yarn. In addition, it is preferable that the single fibers constituting the yarn serving as the entangled yarn have an irregular cross section such as a triangular shape in order to produce a glossy effect. (Function) Next, the function of the present invention will be explained. filament yarn
Y ₀ is unwound from the pirn P, passively supplied by the magnet tensor 14, and guided by the guide 15.
The fibers are sent to a heater 6, twisted and untwisted by a false twisting device 7, and then pulled out by a delivery roller 8. On the other hand, yarn Y ₁ is guided by guides 16, 17, 1
8, 19, active drive roller 20, guide 21, 2
2, 23, is fed from the front of the device, is wound around the filament yarn _Y0 while traversing, and the composite fancy yarn is sent to the heater 6, false twisting device 7, delivery roller 8, heater 9, After passing through two delivery rollers 10, the package is formed into a package 13 by a winding drum 11. (Example) Example 1 Polyester multifilament yarn (50d/24f) was used as filament yarn Y ₀ , and polyester multifilament yarn (50d/24f) was used as yarn Y ₁ .
24f), a fancy yarn was produced under the following conditions using the apparatus shown in FIG. 3, with the feeding rate of yarn Y ₁ being 1.98 times the feeding rate of filament yarn Y ₀ . In addition, the feeding method of yarn Y ₀ , Y ₁
