ABSTRACT:
The invention provides a method for manufacturing spun-bonded nonwoven fabrics that can reduce the diameter of a filament without decreasing productivity and can stably produce nonwoven fabrics, comprising: quenching a multiple number of continuous melt-spun filaments through spinning nozzles with quench air fed to a quenching chamber, drawing the filaments, and depositing the filaments on a moving collector surface, wherein the quench air fed to the quenching chamber is divided into at least 2 streams in vertical direction, and an air velocity of the quench air in the lowermost stream is set higher than that of the 50 quench air in the uppermost stream. The invention also provides an apparatus for manufacturing spun-bonded nonwoven fabrics, wherein quench air fed to the quenching chamber is divided into at least 2 streams in the vertical direction, wherein the velocities of the quench air are independently controllable in the respective streams.
