Abstract

In this study, the improvement of the thermal and acoustic insulation and also electromagnetic radiation properties of polyester (PET) nonwoven fabric (NWF) with 180 g/m(2) weight was investigated. For this purpose, PET NWF was coated with perlite stone powder having 210-590 mu m particle size using polyurethane (PU) based coating. Five different concentrations from 1 to 5 % of perlite stone powder were applied to the surface of PET NWF having five different thicknesses. And then the effect of perlite concentration and its thickness to thermal, acoustic and electromagnetic radiation properties were studied. It was found that the addition of perlite stone powder increased the thermal and acoustic insulation properties of PET NWF. Furthermore, the addition of perlite stone powder does not affect the electromagnetic radiation properties of samples.
