Fiber fabrication method and the fiber fabricated thereby

PURPOSE: A method for fabricating a fiber is provided to simply prepare a polymer fiber by electrospinning different monomer solutions through a nozzle while interfacial polymerization without a complex process. CONSTITUTION: A method for fabricating a fiber comprises: a step of preparing two different monomer solutions(S10); a step of preparing two or more nozzles of which outlets are connected(S20); a step of electrospinning the different monomer solutions through the nozzles while interfacial polymerization to form a polymer fiber(S30); and a step of separating the polymer fiber from a current collector(S40). The polymer fiber contains two or more strands of polymer microfibers of different materials.
