Experimental Section
Materials. The PP used in this study (purchased from PolyMirae Co. of Korea), possessed a melt index of 900-1100 g/min and density of 0.9 g/cm3. The PP non-woven fabrics were prepared using a melt-blown spinning techni-que under an extruder inlet/outlet temperature of 120 °C/230 °C, through-put of 0.1 g/min, air pressure of 0.3 kg/cm2, and die to collector distance of 150 mm.
Heat and Plasma Treatments. The PP non-woven fabrics were heat (densification) treated using a calendar at a pressure of 60 psi, line speed of 4 m/min, press spacing of 0.02 mm, and roll temperature of 120 °C. The PP non-woven fabrics were plasma treated for 5 min under 100% oxygen at a total gas flow rate of 300 cm3/min.
Characterization and Measurements. The surfaces of the non-woven fabrics were investigated using a scanning electron microscope (HITACHI S-3000N).
The tensile strength test was conducted using an Instron mechanical tester (LRIOK model) at a tensile speed of 20 mm/min. All of the mechanical property values were obtain-ed as the average of five experimental values.
The contact angle of the PP non-woven fabrics was mea-sured using a contact angle tester (Dataphysics DCTA 21 model) with de-ionized water as the wetting liquid.
The water flux of the non-woven fabrics was measured using a permeation cell tester (Amicon Model 8050) at pre-ssure of 1 bar and temperature of 30 °C.
The average pore size of the non-woven fabrics was mea-sured using a capillary flow porometer (Porous materials, Inc. CFP-1200-AEL).
The particle removal efficiency of the PP non-woven fabrics was measured using a particle efficiency tester with ISO 12103-A standard particle at a concentration of 3 ppm and flow rate of 11.4 L/min.
