クローズアップされている。In recent years, the speed of false twisting processing of polyester fibers has increased, and high speed processing machines exceeding 600 m/min, especially friction false twisting machines, have become mainstream in the market. Part I
'li! Most of the machines are equipped with a three-axis external type for the rubbing part, but the most important friction member for thread threading is a polyurethane disc in terms of the quality of the processed thread obtained. However, on the other hand, the durability of polyurethane disks has been highlighted as a major problem.

The polyurethane of the flange type plate twister described in Publication No. 8 is used for the disk of the triaxial circumscribed plate twister indicated by -F -C
However, it has poor light resistance and cannot be used stably for a long period of time, which is a practical problem.

されてはいないのが現状である。Therefore, the inventors of the present invention conducted intensive studies to improve the durability of disks whose main component is polyurethane, which has the highest quality of processed yarn. It was discovered that the surface had deteriorated. In other words, the present inventors have already proposed in Japanese Patent Application Laid-Open No. 1983-1972 that the problem of disk life can be greatly improved by covering the false-twisted disk portion so that the disk is not irradiated with such short wavelength light. -11351 Publication), the thread threading operation becomes quite cumbersome, and the disc may be inadvertently exposed to short-wavelength light when storing or assembling the disc (). The current situation is that the problem has not been completely resolved.

ては、加工張力が高いため、高速にすると糸が切れ易く
、ディスク表面に傷が生じては致命的な欠陥となるので
あった。In particular, in simultaneous drawing and false twisting of highly oriented undrawn filament yarns, since the processing tension is high, the yarns tend to break at high speeds, and scratches on the disk surface can be a fatal defect.

にある。From this point of view, the inventors of the present invention conducted further studies, and as a result, they discovered the disk for friction false twisting of the present invention, which actively improves the light resistance over the life of the disk. That is, the present invention improves light resistance and durability by using a specific material of polyurethane as a disk, and also improves the ability to prevent fuzz, etc. from occurring even when a high tension is applied to the yarn during false twisting at the same time as drawing. , high-speed machining can be performed stably for a long period of time.

好ましい。生産性を向−にづるためであ、る。"When drawing and simultaneously false-twisting a highly oriented undrawn filament yarn, a three-wheel circumscribed friction false-twisting device is used as the false-twisting device, and the following monomers are used as friction false-twisting disks of the friction false-twisting device. (R1 and R2 are organic groups in the highly oriented undrawn yarn, which is characterized by using polyurethane as a main component and false twisting the stretching amount by 11.1 times.) [Operations and effects of the present invention] The present invention The present invention is to draw and simultaneously false-twist highly oriented undrawn ficimen 1 to yarn.Since the drawing and false-twisting can be performed simultaneously with -T culm, efficient production is possible.Also, the present invention In this case, the processing speed is preferably 600 m/min or higher, in order to improve productivity.
