More Information
Summary:PURPOSE: A spinning nozzle for a doped solution is provided to ensure high uniformity ratio of fineness and tensile strength and to produce carbon fibers. CONSTITUTION: A spinning nozzle for a doped solution of PAN precursor for carbon fibers has holes for discharging the doped solution, which is formed at the outside protruded in a donut shape. The number of the holes is 3,000 to 48,000. The diameter of the holes is 45-200 micron.
