The present invention relates to a method for oxidation stabilization of nanofibers and nonwoven fabrics for carbon fiber production, and more particularly, by dissolving PAN, pitch, and the like, which are carbon fiber precursor materials, in suitable solvents (DMAc, DMF, THF). After electrospinning 1000nm nanofibers, it continuously oxidizes and stabilizes nanofibers optimally and uniformly in the shortest time by changing variables such as start temperature, end temperature, heating rate, air flow rate, and retention time through a continuous furnace, The nonwoven fabric is transferred to the stabilization furnace through the conveyor belt to optimize the conditions of start temperature, end temperature, heating rate, air flow rate, holding time, and hot wind direction to oxidatively stabilize carbon nanofibers or carbonized nonwoven fabrics with uniform physical properties. can do. |
