Abstract
PURPOSE:To maintain spinning temperature uniform in high precision and to obtain high-performance pitch-based carbon yarn having stable qualities, by subjecting a petroleum-based or coal-based pitch to melt spinning by using a spinneret equipped with a heat pipe. CONSTITUTION:A petroleum-based or coal-based pitch is subjected to melt spinning by using a spinneret having nozzle hole delivery parts 9 and equipped with heat pipes 10 to maintain spinning temperature uniform in high precision by the heat pipes and to obtain high-performance filamentous pitch-based carbon yarn having stable qualities. The heat pipes have a tubular shape of circular section and >=6mm outer diameter and the shortest distance from the outer wall face of the heat pipes to the nozzle delivery part is preferably <=20mm.
