In this study, 25gsm melt-blown polypropylene nonwoven for dust-proof/medical masks was finished by the
corona discharging treatment. The influence of corona discharging parameters on the filtration efficiency was investigated.
Several parameters such as discharging voltage, discharging speed, distance to discharging wire and configuration of
discharging system had an effect on filtration efficiency, while the parameters had no effect on breathing resistance. Optimum
corona discharging conditions are as follows: Wires were installed on the upper part of the nonwoven and paper pipe was
installed on the lower part of the nonwoven having a distance of 5cm. The sequence of wire voltages was +60 kV, +60 kV,
0, -60 kV, and -60 kV. The discharging voltage and speed were 60 kV and 30m/min respectively. The nonwoven treated by
corona discharging at the optimum condition showed a filtration efficiency of 80% or more, which is suitable for
dust-proof/medical masks. |
