Abstract: The present invention relates to a method for manufacturing a melt-spun nonwoven fabric and a microfiber nonwoven web manufactured therefrom. The present invention relates to a method for manufacturing a melt-spun nonwoven fabric, in which fibers obtained by melt-spinning a thermoplastic polymer through a spinning nozzle including at least one nozzle hole are collected by high-speed air stream, wherein the melt-spun fibers are subjected to momentary local heating at a high temperature higher than a spinning temperature while same are caused to pass through a nozzle local heating provided directly under the spinning nozzle during spinning, so that the method can lower the melt flow index and spinline elongation viscosity of a thermoplastic resin discharged from the nozzle hole without reducing a molecular weight, thereby providing a microfiber nonwoven web formed by finely thin fibers, compared to the conventional spun-bond nonwoven fabric.
