Abstract
PURPOSE: To prevent fluffing of filament yarns due to the static electricity, to improve the operational rate of calcining step, and to obtain high-quality carbon fibers, by applying a specific amount of water uniformly to a high-temperature filament yarn after the drying step in a specific atmosphere.
CONSTITUTION: A filament yarn obtained from an acrylonitrile polymer consisting of 90wt% or more of acrylonitrile is dried. 0.2wt% or more of water based on the fiber weight is applied to the yarn uniformly to form a calcination yarn without static electricity, and fluffing, spreading, and breaking. The yarn of good apparent coherency is then calcined to give carbon fibers of high strength and modulus in a high productivity, without causing static trouble even with no antistatic oil harmful to the quality.
