Abstract

PURPOSE:To stably obtain the titled high-quality fiber having excellent yarn physical properties without mutual adhesion, etc., with excellent process passableness and yarn separating properties, by using an oiling agent prepared by blending a straight-chain silicone oil with a surfactant as a binder for pitch fibers. CONSTITUTION:A binder consisting of an oiling agent prepared by blending a straight-chain silicone oil with a surfactant is initially applied to pitch fibers obtained by melt spinning raw material pitch to bundle the above-mentioned pitch fibers. The resultant fibers are then infusibilized and carbonized to afford the aimed fiber. Furthermore, dimethylpolysiloxane and methylphenylpolysiloxane are preferred as the straight-chain silicone oil. The afore-mentioned binder is preferably adjusted to 5-50cSt viscosity for providing an uniform pickup in the pitch fiber.
