Spinning nozzle apparatus for manufacturing high-strength fiber
The present invention relates to a spinning nozzle apparatus for manufacturing a high-strength fiber.The spinning nozzle apparatus for manufacturing a high-strength fiber according to the present invention is designed to optimize a heating method for the spinning region of a spinning nozzle in the melt spinning process. The heat transfer method is optimized by disposing the spinning nozzle holes of spinning nozzle commercially available on the outside of, directly under the pack body and heating the spinning nozzle holes with a heating body. In addition, an instantaneous heat treatment at high temperature is adopted to control the molecular entanglement structure in the melted polymer, which enhances the drawability of the thermoplastic resin and hence improves the mechanical properties such as strength and elongation.
