摘要： The present invention relates to a spunbonded filament nonwoven fabric and a method of preparing the same, and particularly to a multilayered spunbonded filament nonwoven fabric of which the fineness of the filaments decreases from an air inlet part toward an air outlet part, and a method of preparing the same. The spunbonded nonwoven fabric of the present invention can be used as an air filter for power generation equipment for a gas turbine, because it can reduce a pressure loss, promote filter efficiency, and extend the lifetime for use by using fiber layers having different denier.
