Abstract
PURPOSE: Acrylonitrile copolymer fiber that has a specific composition susceptible to heat oxidation is directly subjected to heat oxidation treatment, then carbonized to produce title fiber with high and stable performance including high lightness and tenacity.
CONSTITUTION: An acrylonitrile copolymer fiber is made from 85mol% or more acrylonitrile, 0.1W1-mol% of a vinyl carboxylate monomer and 0W10mol% of other copolymerizable monomers. The heat oxidation treatment is effected at a temperature at least 40W80°C higher than that at which the copolymer starts evolving heat to form the flameproofing fiber with a conversion gradient from the surface to the inner layers of the fiber. When the resulting flameproofing fiber is subjected to carbonization, the surface layer with high reaction rate is carbonized as it is whereas the center core causes decomposition and evolves gases to form the hollow part.
