摘要： PROBLEM TO BE SOLVED: To provide a method for infusibilizing a pitch fiber, which does not form hot spots in ultrafine pitch fibers, avoids ignition and eliminates waste acid treatment and waste alkali treatment.
SOLUTION: Infusibilization treatment is carried out by passing an oxidizing gas through a pitch fiber in a state in which the pitch fiber is in contact with water. For example, a slurry 10 obtained by mixing a pitch fiber with water and a surfactant is held in a container 1 and an oxidizing gas is introduced from a gas introduction pipe 4 into the slurry 10. Bubbles of the gas are generated in the slurry 10 and brought into contact with the pitch fiber.
