摘要： PURPOSE: To prevent the troubles in the handling of solidified pitch, by dividing the thermal polymerization process of pitch in two stages, heat-treating the pitch in the first thermal polymerization step until the pitch is about to form the mesophase, storing the product in liquid state, and supplying the liquid to a spinning apparatus furnished with a vacuum thermal polymerization apparatus.
CONSTITUTION: Pitch is made to react with a hydrogen-donative solvent, alcohol, phenol, etc., and the solvent is removed from the reaction product. The processed pitch is subjected to the thermal polymerization at 400W500°C to the state immediately before the formation of meso-phase, and is stored in liquid phase. The stored liquid pitch is supplied to a spinning apparatus furnished with a vacuum thermal polymerization apparatus, heated quickly to 400W550°C under reduced pressure to develop the meso-phase, and is spun as it is to obtain the objective pitch fiber.

摘要： PURPOSE:To obtain a carbon fiber having well aligned single filaments and free fluffs, by collecting the melt-spun pitch fiber in a reservior, infusibilizing the fiber in a perforated container under forced ventilation, and carbonizing or if necessary graphitizing the product under specific condition. CONSTITUTION:Melt-spun pitch fiber is taken off in a reservior without using a collecting agent by an air-stream take-off device, and infusibilized by heating in a container having ventilation holes in an oxygen-containing gas under forced ventilation. The obtained fiber is heated in an inert gas atmosphere until the breakage elongation of the fiber reaches >2.5%, preferably >3.0% to effect the primary carbonization. The carbonized fiber is transferred with a roll under tension through a carbonization furnace to effect the secondary carbonization or further the graphitization. The disturbance of the agglomerated state of the filaments can be prevented by this process.

摘要： PURPOSE:To obtain the titled fibers having remarkably improved tensile strength and modulus of elasticity, by winding fibers prepared by spinning a pitch around a bobbin or reel, developing the strength of the fibers in the carbonization step, increasing the peripheral length of the part of the bobbin or reel wound by the fibers, and drawing the fibers. CONSTITUTION:Fibers 3 prepared by spinning a pitch are wound around a cylindrical bobbin 1 consisting of a drum 2 divided into equal parts in the axial direction, and the peripheral length of the part of the bobbin 1 wound by the fibers 3 is increased to give a stage (b) at a suitable period after developing the strength of the fibers 3. Thus, the fibers 3 are drawn by giving a tension thereto. Alternatively, the fibers 3 are held by a reel 1 consisting of a pair of frames 4 and 4', which are then separated in the outward directions (A) and (A') by a wire, etc. to increase the winding width. Thus, the peripheral length of the reel 1 is increased to draw the fibers 3 by giving the tension thereto.
