2. Description of the Related Art Synthetic fibers are widely used in various fields including general clothing fields due to various excellent properties including mechanical properties. In clothing applications, the quality has been improved by targeting natural fibers, and in particular, in order to give the drawn yarn insufficient bulkiness, false twisting is performed at the same time as drawing, and a texture with a feeling of bulkiness has been obtained.

Further, for the purpose of imparting a dry feeling, it has been proposed to impart a dry feel by reducing the contact area when the cloth is made by imparting irregularities to the cross-sectional shape of the single yarn of the synthetic fiber yarn. . However, there is a limit in providing unevenness due to the difficulty of forming the single yarn cross-sectional shape, and when false twisting is performed,
There is a problem that the feel of the woven or knitted fabric is unsatisfactory and the softness is insufficient, and in particular, the cross-section is largely deformed by false twisting, and the effect of the cross-section is not utilized in the woven or knitted fabric. Further, processing at high temperature is required to maintain sufficient bulkiness and crimp characteristics, and there is also a problem that the shrinkage rate is low.

Further, Japanese Patent Application Laid-Open No. 1-183540 is known as a technique for using a highly shrinkable yarn to reduce cross-sectional deformation and to produce a high-density fabric. However, according to these two methods, since the false twisting is performed while heating at a temperature not higher than the glass transition point, the workability is deteriorated and it is not suitable for industrial production.

FIG. 4 shows an example of the false twist textured yarn of the present invention.
The false twisted textured yarn according to the present invention has an X-shaped cross section in which the constituent single yarn has four lobes on the periphery thereof in order to maintain a dry feeling, a water absorbing property and a quick drying property when formed into a fabric. The bending angle is 145 degrees or more and 175 degrees or less. It is preferably 150 degrees or more and 175 degrees or less, and more preferably 150 degrees or more and 170 degrees or less. Bending angle is 1
If the angle is less than 45 degrees, the cross-section deformation of the single yarn becomes large, and the difference between the protrusion and the recess becomes small. As a result, the voids between the fibers are also reduced, and the dry feel, water absorbency, and quick dryness are impaired. When the bending angle exceeds 175 degrees and is 180 degrees or less, the single yarn is not substantially deformed in cross section,
When made into a fabric, it lacks drape, softness, and swelling, and has no new feel.

FIG. 2 is a process drawing showing an example of the method for producing the false twist textured yarn of the present invention. In FIG. 2, the undrawn yarn 20 is wound around a heating roll 22 and a separate roll 23 several times via a feed roll 21 and preheated, and a twisting prevention device 25, a false twisting tool 26, and a heatable take-up roller 2 are provided.
Stretching false twisting is continuously performed by using a twist stopping device 25 provided at a point different from the point 24 where the heating roll 22 and the yarn are separated between 7 and 7 as a heating start point. Then, after passing through the unheated stretch roll 28, it is wound up as a pan 29 using a spindle type winding device. The drawing false twist continuous processing of the present invention may be the above-mentioned indrow method or the outdraw method.

According to the above-mentioned method of the present invention, since the twist fixing is performed by the heat which the yarn receives from the heating body, the twist fixing force is small. Therefore, the false twisted yarn obtained by the present invention does not have high crimpability as the conventional false twisted yarn due to the deterioration of drapeability, swelling feeling, and softness in the fabric, and is made into a woven or knitted fabric. In this case, the drape property is good, the swelling feeling and the soft feeling are excellent, and a new feeling different from that of the conventional drawn yarn or false twisted yarn can be exhibited. Further, unlike the conventional false twisting method, since the synthetic fiber yarn is heated in a non-twisted state, it is possible to apply a uniform and sufficient amount of heat to all the single yarns in the yarn. Furthermore, since the twisting device provided at a position different from the point where the yarns on the heating element are separated is used as the twisting start point, the twisting back to the heating element can be prevented, and fluff and yarn breakage do not occur.

The drawn false-twisting method of the present invention is excellent in processing stability and quality uniformity because the drawn false-twisting process is carried out at the glass transition point or higher. The temperature of the heating roll 22 may be appropriately set according to the type of the synthetic fiber yarn to be used, the desired crimping performance, the processing speed, etc. It is preferably at least the glass transition temperature of the fiber yarn. Further, the number of windings around the heating roll 22 may be appropriately set according to a desired heat quantity,
In order to prevent the yarn from slipping, it is preferable that the number of times is four or more. If the take-up roll 27 is a roll that can be heated similarly to the heating roll 22, the false twisted yarn can be heat set, and the two-stage heater false twisted yarn can be easily manufactured. Moreover, since the temperature of the take-up roll 27 can be arbitrarily selected, the shrinkage rate of boiling water can be made higher than that of the conventional false twisted yarn.

It is preferable because the rolling property can be improved. Further, in order to improve the unwinding property of the false twisted yarn, an air entanglement nozzle (not shown) may be provided between the stretch roll 28 and the separate roll, and entanglement may be imparted using the air entanglement nozzle. More preferable.
