Özet
In this study, polyester (PET) nonwoven fabrics with different weights were coated with perlite stone powder with particle sizes between 210-590 ?m. Before coating procedure, water repellency treatment was applied to the samples and then the same amount of polyurethane base coating with perlite stone powder was applied on the nonwoven samples. After coating, the samples were cured at 100°C for 10 minutes. Finally, air, heat, and sound permeability of samples were investigated with regards to the weight of samples. According to the results, the increase in weight of samples caused to improve air permeability and acoustic insulation of samples. Furthermore, the decrease in weight of samples caused to decrease in the thermal conductivity coefficient of samples.
