초록

Flash-spun nonwoven has high barrier properties, so the pressure difference is higher than other nonwoven. This characteristic can be controlled by adjusting the volume of the pressure drop nozzle during the flash spinning process. To control the characteristics, flash spinning was performed by designing the volume of the pressure drop nozzle. The shape and diameter distribution characteristics of the flash-spun fibers were analyzed. To evaluate the possibility of a filtering material, the fibers were chopped to prepare a wet-laid nonwoven. Air permeability and filtration efficiency were evaluated for the prepared wet-laid nonwovens. The properties of the wet-laid nonwoven were correlated with the dispersion value of the flash spun fibers. Wet-laid nonwoven manufactured based on flash-spun fibers is expected to be applied as a filter medium because the differential pressure can be lowered through process control.
