Abstract:
A process for producing carbon fiber or graphite fiber is provided. The process comprises spinning a carbonaceous pitch, doubling spun pitch fiber bundles, adding a heat resistant doubling treatment oil, passing the fiber bundles continuously and linearly through an oxygen rich gas, infusibilizing at a temperature of 350.degree. C. or less, then carbonizing or graphitizing infusibilized fiber bundles.
