INVESTIGATION OF THE PHYSICAL PROPERTIES OF MELTBLOWN NONWOVENS FOR AIR FILTRATION

Textile filters are industrial textiles used in filtration applications. Among textile materials, especially nonwovens are suitable for filtration applications, because of their complex structures and appropriate thickness. Nonwoven filters are used in various application areas of technical textiles such as medtech, mobiltech, protech, packtech and hometech. Meltblown nonwovens are a unique class of materials, characterized by high surface are, porosity, softness and absorbency due to their microstructure. In this study polypropylene meltblown nonwovens were produced for the purpose of air filtration. Physical properties, namely thickness, basis weight, tensile properties, air permeability, and fibre diameter of were measured and effect of various production parameters on the physical properties of PP meltblown nonwovens were investigated and possibility for using such materials in air filtration was discussed.
