PURPOSE: A method for fabricating a synthetic fiber for fiber reinforced concrete is provided to increase specific surface area by changing cross section of the synthetic fiber, and to improve mechanical adhesion performance by processing the longitudinal direction shape to a double crimped shape. CONSTITUTION: A method for fabricating a synthetic fiber for fiber reinforced concrete comprises: a step of injecting the synthetic fiber in a specific surface area-increasing cross section shape(S120); a step of forming the synthetic fiber with a double crimped shape(S210); and a step of completely curing the synthetic fiber and cutting in a desired length. The synthetic fiber increases the specific surface area and adhesion performance with a cement composition.
