Acoustic and Thermal Properties of Polypropylene Carpets: Effect of Pile Length and Loop Density
Merve Küçük,Yasemin Korkmaz 한국섬유공학회 2019 Fibers and polymers Vol.20 No.7
Sound control in office and living environments is cruical for creating a peaceful and relaxing occupation forindividuals. Improvement of sound absorption properties of textile materials used in architectural structures has become anissue of importance. The study here is focused on acoustic characterization of polypropylene carpets used in the indoorenvironments. Due to growing interest in mass, volume and cost efficient multifunctional materials, additionally thermalconductivity of the carpets have been studied. Polypropylene carpet samples were prepared with four different pile length andtwo different loop density parameters. It has been observed that loop density and pile length parameters affect thermalproperties and sound absorption rates all frequency ranges. Anova analysis for sound absorption revealed that the combinedeffect of loop density and pile length parameters is evident in the mid-to-high frequency ranges.
