<Industrial Application Field> The present invention relates to a method for producing a false twisted yarn having loops and entanglements mainly composed of polyester fibers.
More specifically, first, the filament is subjected to a low false twisting process to generate a full amount of torque, and then a strong fluid treatment is applied to create snarl-like loops and entanglements, resulting in processed yarn for clothing that has a silk-like texture. The present invention relates to a manufacturing method.

<Conventional technology> Special yarns with loops and entanglements have been developed for a long time, and drawn yarns,
Many methods have been introduced, including methods of using processed yarns or yarn-supplying spliced yarns.0 However, these methods using taslan nozzles are used because the conventional method using interlace nozzles does not generate sufficient loops.・The purpose is to use a nozzle to generate a snarl-shaped loop using strong fluid pressure. However, the cost required for these taslan nozzle devices and strong fluid pressure is large, and the equipment and yarn feeding method are not easy.

<Problems to be solved by the invention> In contrast to these methods of exploding special threads with loops and entanglements using Taslan nozzles, which have many problems in terms of operability and cost, this method can be easily and rationally produced. The present invention is the result of various studies regarding the method. That is, during false twisting, by performing false twisting with an extremely low number of twists that deviates from the commonly accepted number of twists, the snarling force, or torque, of the yarn and individual filaments can be significantly increased.

The present inventors focused on this point, and when the filament of this torque dog is subjected to an economical fluid treatment under an oversupply condition, the filament spontaneously forms a 5-snarl loop and becomes entangled. We found that the ties between departments also became stronger.

Means for Solving the Problems〉 That is, the present invention performs false twisting or stretching (simultaneous or continuous) so that the number of twists (4) satisfies the following formula,
This is a method for producing a special false-twisted entangled yarn, which is characterized in that the yarn is then subjected to an entanglement treatment under conditions of 3 to 20% excess supply to form snarl-like loops of 50 or more per meter.

(However, Dr is the drawing calculation property, and the unit of A is times/m.) According to the method of the present invention, false twisting with a low number of false twists is performed, so flattening of the cross section as in conventional general false twisting is not possible. There is no excessive crimp, and although it looks like a drawn yarn, it can add loops and entanglement points in addition to the bulkiness due to false twisting, making it possible to obtain a filament yarn suitable for silky texture. That will happen.

The biggest point in this invention is the low false twist number +400
It is necessary to have a low false twist number of 85 or less (this formula is defined as B). This results in a large yarn torque, a snarling of the generated loop, and a strong entanglement point. Even if the number of twists is 85 or less for type B, if it becomes 20 to 25% or less, the yarn torque becomes small again, so the appropriate number of twists is 0.2B to 0.
.. It would be called 85 B.

In addition, as mentioned above, since these false twisted yarns are like drawn yarns, it is desirable to aim for a silk-like texture, and it is desirable to have a T-type or 5-inch texture.
By using a bright yarn having a rectangular irregular cross section, a fabric having an appearance and feel that can be called spun silk can be obtained.

Furthermore, by using a yarn with a thick division in the out-draw part or a drawn yarn with a thick division, a fabric with a special appearance and feel can be obtained, and at the same time it can be treated with a stronger entanglement. By performing heat treatment at 150° C. or higher in this region, large loops and bulkiness are reduced, but the quality of the yarn is stabilized, resulting in a yarn with good unwinding properties and ease of passing through subsequent processes.

As mentioned above, the setting of the number of false twists in ■ is 0.2B~・0.85
It is necessary to set it in the range of B, and it is preferable to set it in the range of 0°4B to 0.7B, where the yarn torque is the best (-1, as the number of false twists decreases, the false twist tension increases [In order to , the dyeing result tends to be a dark color.Adjusting the entangling fluid pressure and excess supply rate after false twisting in ① and increasing the number of loops and entanglements as possible to achieve a soft texture. If this is the case, it is desirable to increase the fluid pressure and reduce the excessive supply rate, but if an excessive loop occurs, the unwinding property from the cheese will be poor, and this will have a negative impact on the subsequent process, so it is generally not recommended. A typical interlaced nozzle is preferably 6 to 5 to 9 mm, and the excess supply rate is preferably about 3 to 13 inches, and the tension before and after the nozzle is preferably about several grams.

If you want to slightly soften the countless loops that have been generated and add yarn shape and thermal stability, it is desirable to add heat treatment in the interlace entanglement treatment area (between the rollers) or after that. Unwinding performance is also improved. At this time, the heat treatment temperature can be expected to be effective at temperatures ranging from 80°C or higher to around 240°C, but below 150°C there is little effect due to the thermal history of false twisting, and if the heat treatment temperature is increased to around the melting point, the loops may become smaller. The temperature is preferably about 170 to 220°C, since this tends to result in an excessively low thermal shrinkage rate after treatment. In addition, it is preferable to increase the excess supply rate when using a second Hilter than when not using it.
7 to 15 inches is desirable l-, -, < In this case, the tension before and after the nozzle is preferably about a few grams.In addition, as mentioned above, since a silk texture can be expected, fine It is desirable to use bright yarns with fineness and irregular cross-sections such as pentagonal or T-shape.

In the processed yarn (a) obtained at 2%, the loops do not become snarled, and the loops easily disappear by slight tension or twisting, and there is also the possibility of winding and breakage due to the processed yarn slacking in the entangled area during false twisting. There were many. Processed yarn (e) had a low excess supply rate and fluid pressure, the number of snarled loops was less than 30/m, the occurrence of loops was small, and only the torque was large. On the other hand, processed yarns (b), (c), and (d) have countless snarl-like loops, and the loops do not disappear even when tension is applied until cutting or after complete twisting. A fabric with a spun texture and luster was obtained. Note that in cases a to d, the number of entanglements was 100 or more, whereas in case e, the number of entanglements was around 25.
