[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a spinning device and relates to a spinning device suitable for manufacturing optical fibers. [Background of the Invention] A conventional thermoplastic resin fiber fiber device is As shown in the figure, the spinning dope 3 in the resin melting tank 2 is sent to the spinning nozzle 5 with a metered discharge bong 4, and the yarn is discharged from the spinning nozzle 5.
After cooling and hardening in a cooling section 6, the material is wound up in a winding device 7.

In addition, it is very difficult to prevent the orientation of this molecule (it has the disadvantage of having to spin with V and having poor ambiguity, and
The higher the molecular buds, the easier the molecules are to be oriented, so conventional equipment cannot produce optical fibers made of high-molecular-weight thermoplastic resins. The spinning device shown in Fig. 1 is for thermoplastic resin, and when trying to spin thermosetting resin fibers, the spinning dope must be heated upstream of the spinning nozzle 5 to prevent it from hardening. However, if heating is performed in the melting tank 2, the polymerization reaction will proceed significantly due to the viscous heat generated by the metering discharge pump 4, and the yarn will not be able to be spouted, and if only the spinning nozzle 5 is heated, the upper and lower parts of the nozzle Since the length is short, it is difficult to control the temperature, resulting in problems such as insufficient gelation, too much reaction and failure to discharge filaments, or non-uniform filament diameters. Therefore, the conventional thermal oJ1it1 resin fiber yarn device could not be practically applied to spinning thermosetting resin. It is an object of the present invention to provide a spinning device capable of spinning fibers without causing any optical distortion.
