The present invention relates to a circumscribed friction false twisting device for the purpose of imparting false twist to running threads, and particularly in drawing false twisting of synthetic fibers, it has excellent durability at high speeds and high quality. This invention relates to a friction false twisting device for obtaining textured yarn. In general, various devices have been proposed as a means of imparting false twist to synthetic fibers, but the circumscribed friction false twisting device is particularly effective in the draw false twisting method in which semi-drawn yarn is simultaneously stretched and false twisted. Recently, the number of uses has increased significantly due to the ability to increase processing speed. Therefore, the combination and material of the friction disks constituting such a circumscribed friction false twisting device may be changed, for example, by using two metal satin friction disks at the top and bottom, solid ceramic, ceramic coating, or diamond. Various considerations have been made, such as using materials with excellent wear resistance such as coatings. However, even with these improved circumferential friction false twisting devices, the yarn false twisting speed cannot be increased.
When processing at a high speed of 400 m/min or higher, the same friction disk configuration as used at lower processing speeds will not provide sufficient twist, and the material of the friction disk may be of high quality such as polyurethane rubber. In the case of molecular compounds, wear of the friction discs significantly shortens their service life. On the other hand, if the friction disk is made of a material with excellent wear resistance, such as solid ceramic, the twisting efficiency is lower than that of polyurethane rubber, and the yarn surface is more likely to be damaged. Not only was the quality of the processed yarn inferior, but it also had the disadvantage of being prone to fluff. In addition, when a polymer compound such as the polyurethane rubber mentioned above is mainly used as the material of the friction disk, from the viewpoint of stabilizing the running of the yarn and suppressing the wear of the polyurethane rubber friction disk, two sheets are inserted from the yarn entrance part. It has also been considered to make the friction disks made of satin metal or solid ceramic with a roughness of 1S or less, but even if such materials were used, they would not be able to be false-twisted at high speeds of 600 m/min or more. When processing, even under conditions where the thread path of the yarn running on the surface of the friction disk is stable, there is a drawback that the polyurethane rubber friction disk wears out much faster than during low-speed processing. By the way, as the false twisting speed increases,
In order to maintain a certain level of twist, it becomes necessary to increase the number of friction discs. Furthermore, if the same conditions are set as during low-speed processing, the running of the yarn within the friction disk group becomes unstable, causing tension fluctuations, resulting in untwisting, fuzzing, and even yarn breakage, but this problem can be solved. In order to achieve this, it is necessary to increase the yarn tension within the group of friction disks. On the other hand, the wear of the polyurethane rubber friction disk at the yarn entrance is thought to be due to torque being applied to the friction disk due to sudden twisting on the friction disk. The wear of the friction disk at the exit section is thought to be due to untwisting at the yarn separation point on the friction disk and the application of torque in the opposite direction to the previous torque on the friction disk. These forces will become stronger as the false-twisting tension increases, so increasing the false-twisting speed will result in more severe wear on the polyurethane rubber friction disc. . The object of the present invention is to provide a circumscribed friction false twisting device that solves the problem of reducing the number of twists and the contradictory problems of stable yarn running and wear of polyurethane rubber friction disks. That is, the present invention provides a circumscribed friction false twisting device having a plurality of shafts, in which each of the friction disks at the yarn inlet and yarn outlet is made of satin metal or solid ceramic with a roughness of 1S or less. Of the n friction disks between the above two friction disks, m of the friction disks closest to the yarn entrance and the one closest to the yarn exit are made of solid material with a roughness of 2S or more and 6S or less. It is made of ceramic, and the remaining n-(m+1) friction disks are made of polyurethane with a roughness of 5S or less, and n and m are n≧6, 1≦m≦n/2 (n and m are integers). This is a friction false twisting device that satisfies the following range. Further, the present invention will be explained in detail using the drawings. FIG. 1 is a front view showing an example of a false twisting device of the present invention. Three shafts 1, 2, and 3 are provided on a bracket 20 of a false twisting device so as to be located at approximately the vertices of an equilateral triangle. At the bottom end of each shaft are pulleys 14, 15,
The drive pulley 19 at the lower end of the shaft 2 transmits rotation according to the movement of the drive belt 18 to the pulleys 15 and 16, and the rotation is transmitted to the pulleys 14 and 17 connected by a timing belt.
The shafts 1, 2, and 3 rotate in the same direction and at the same speed. Friction disks 4 to 13 are arranged on the shafts 1, 2, and 3 so as to overlap and cross each other, as shown in FIG. 1, for example. Among these friction disks, it is difficult to regulate the intersecting angle between the yarn Y and the friction disk to a desired angle in the friction disk 4 at the yarn entrance, and this portion is made of a material that has a substantial twisting effect. Placing a friction disk causes frequent fuzzing and yarn breakage. Similarly, if the friction disk 13 is made of a material that has a twisting effect, the untwisting point will be unstable, which will cause untwisted parts to occur frequently.
Therefore, it is necessary to provide the friction disks 4, 13 with friction disks that do not substantially have a twisting effect.
Friction discs 4, 1 from the viewpoint of wear resistance and thread separation properties
3 must be made of metal satin or solid ceramic with a roughness of 1S or less. Next, among the n friction disks (n=8 in Fig. 1) located between the friction disks 4 and 13, one to n/2 disks from the yarn entrance, and one to n/2 from the yarn exit. In the closest one, that is, the friction disk illustrated in FIG.
By making the friction discs 8 and 12 made of solid ceramic with a roughness of 2S or more and 6S or less, it is possible to prevent wear of the friction discs due to the torque generated at the yarn entrance and yarn exit. In addition, maintaining high twisting efficiency and stable running,
In order to obtain a processed yarn with good quality, it is more preferable that the number of ceramic discs be 2 or more and n/3 or less. These (m+1) solid ceramic friction disks arranged at the yarn inlet and outlet sections may be made of other wear-resistant materials, such as diamond coating, from the sole purpose of preventing wear of the polyurethane disks. , ceramic frame plating, etc. can be used instead, but when friction discs made of these materials are used, white powder, fluffing occurs frequently, and the strength and elongation of processed yarn decreases, resulting in poor quality, which is the objective of the present invention. It is not possible to obtain a good thread quality. The n-(m+1) friction disks that follow the m solid ceramic friction disks placed at the yarn entrance have a roughness of 5S or less, which has a large twisting effect and causes little damage to the yarn. A polyurethane friction disc is used. When the yarn is guided by these friction disks, the solid ceramic disk placed above it has already stabilized the yarn, and the number of twists has already reached a certain level. , the torque applied to the disk becomes very small. After the yarn has been given a higher level of twist on the polyurethane friction disks, it has not yet been untwisted when it leaves the disk, so no large torque is applied on these friction disks. . Therefore, the wear of these polyurethane discs does not become too severe even when the false twisting tension is increased. Furthermore, these n-(m+1) polyurethane friction disks are essential in order to maintain a higher twist level. The present invention is constructed as described above, and is a conventional false twisting method in which one metal friction disk is placed at the yarn entrance and the yarn exit, and a polyurethane friction disk is placed between them. Compared to the device, almost the same fluff and thread quality were obtained. Furthermore, the present invention can alleviate fluctuations in the twisting tension and wear of the friction disks during high-speed false twisting, making it possible to significantly extend the replacement cycle of the friction disks. In addition, compared to the conventional device which is an improved version of the above structure and has a structure in which several disks at the yarn entrance are made of metal, the present invention has the same number of friction disks, but the twisting Since the number of effective friction disks has increased, a high number of twists can be achieved, and tension fluctuations are also small. Furthermore, compared to devices in which all disks are made of solid ceramic material, which has been widely used in recent years to prevent wear of friction disks especially during high-speed machining, the twisting efficiency of the present invention is much higher. A good processed yarn with less fuzz and excellent strength and elongation and crimp properties can be obtained. The entire friction disk of the present invention may be made of a specified material, or only the portion where the threads come into frictional contact may be made of a specified material, or may be coated. Furthermore, the axis of the false twisting device to which the present invention is applicable is 2 to 2.
Although four axes are preferred, having three axes provides a significant effect. As shown above, by using the friction disk configuration according to the present invention, stable operability and uniform machining can be achieved during high-speed machining compared to conventional friction disk configurations made of various materials. It becomes possible to satisfy the yarn physical properties at the same time. This will be explained below using examples. Example 1 3 as shown in Figure 1, consisting of a total of 10 friction disks.
Using a friction false-twisting device with a book shaft, friction disks made of satin metal, friction disks made of solid ceramic with a roughness of 3S, and friction disks made of polyurethane with a roughness of 1.5S are shown in Table 1. The configuration is as follows, and the spinning speed is
The polyester semi-drawn yarn obtained at 3500 m/min was used as the feed yarn, and the processing speed was 600 m/min using a normal drawn false twisting device equipped with the friction false twisting device, a 2 m long heater, and a 1 m long water-cooled cooling plate. A 150-denier 48 filament false-twisted yarn was obtained by drawing and false-twisting, and the number of twists, strength, elongation, and number of fuzz were examined. The results are shown in Table 1.

[Table] Experiments Nos. 1, 2, 6 and 7 are comparative examples for clarifying the effects of the present invention. According to these results, although the configuration shown in Experiment No. 2 is somewhat satisfactory in terms of yarn quality, the large fluctuations in untwisted tension result in variations in the number of untwisted strands. In , 2, the replacement cycle of the polyurethane rubber friction disk is short and cannot be adopted as a production condition. On the other hand, in the configurations shown in Experiment Nos. 6 and 7, the number of twists,
A good false twisted yarn cannot be obtained from a trowel that has low strength, low elongation, and a large number of fuzz. Compared to these comparative examples, Experiment Nos. 3, 4, and 5 of the present invention not only have superior thread quality, but also have polyurethane rubber friction discs replaced about 2.5 to 3 times as often as before. It became possible to extend it. Example 2 In a friction false twisting device having three shafts as shown in Fig. 1, consisting of 10 sheets in total, friction disks 4 and 13 were made of satin metal, and friction disks 7 to 11 were made of polyurethane with a roughness of 1.5S. . Then, the roughness of the friction disks made of solid ceramic arranged on the friction disks 5, 6, and 12 was varied as shown in Table 2, and stretching and false twisting was performed. The processing speed is
600m/min. A polyester semi-drawn yarn obtained at a spinning speed of 3500 m/min was used as a supplied yarn to obtain a false twisted yarn of 150 denier and 48 filaments. The results are shown in Table 2.

[Table] Experiments No. 8 and 11 are comparative examples for clarifying the effects of the present invention. According to the results of the actual number of twists and number of fuzz in Table 2, the experiment
When the roughness is set to 1S as in No. 8, the actual number of twists decreases, and conversely, when the roughness is set to 6S or more as in Experiment No. 11, fluffing increases, and in both cases, the processed yarn is good. It didn't happen. Experiment Nos. 9 and 10 were within the scope of the present invention, and good processed yarns were obtained. Example 3 In a friction false twisting device having three shafts as shown in Fig. 1, which consists of 10 sheets in total, the disks 4 and 13 are made of satin metal, and the disks 7, 8, 9, 10, and 11 are made of metal with a roughness of 1.5S. Example 1 except that it was made of polyurethane and 5, 6, and 12 were changed to three types: solid ceramic (roughness 3S), diamond coating (roughness 1.8S) ceramic frame, and plating (roughness 5.5S).
Stretching and false twisting were carried out under the same conditions as above. The results are shown in Table 3.

According to the results in Table 3, when materials 5, 6, and 12 are made of diamond coating or ceramic frame plating, it is thought that there is not much difference from solid ceramic in terms of wear resistance.
It is not suitable for the purpose of the present invention because it has low strength and elongation, produces a lot of fuzz, and produces a lot of white powder. On the other hand, when the solid ceramic according to the present invention was used, a good false twisted yarn with high strength and elongation and little fuzz and white powder was obtained.
