METHOD FOR MELT SPINNING OF PITCH MATERIAL

摘要

PURPOSE:To make stable spinning possible, by blowing an inert gas on pitch yarn spun from great number of nozzle holes at a specific position in a specific direction. CONSTITUTION:An inert gas is blown on pitch yarn 3 spun from a great number of nozzle holes of a nozzle head at a position within 50mm from the face of the nozzle head 1 in the horizontal direction or slantingly downward direction. Preferably the inert gas is blown from the inside to the outside of the nozzle head 1.
