ABSTRACT:
High-performance carbon fiber or graphite fiber can be produced by treating the preoxidized fiber or carbon fiber strand with an aqueous solution containing at least one member of polyethylene oxide having a molecular weight greater than 100,000, methyl cellulose, ethyl cellulose, and hydroxyethyl cellulose, and drying the treated fiber strand at a temperature lower than 250.degree. C. prior to carbonization or graphitization.
