Abstract

We approached Fehrer AG, a world-renowned textile machines and nonwovens machine manufacturing company of Austria, with a request to provide us with their latest automotive nonwoven fabrics. The company is known for its invention-oriented nonwovens technology developments. They supplied us with four aesthetically pleasing flat, rib and random velour nonwoven fabrics that can be used as automotive linings for floor, trunk, or doors. They also supplied us with three automotive insulation highloft products produced with Fehrer's V21/R-K12 highloft aerodynamics web-forming technology that use recycled "shoddy" fibers and bicomponent fibers for acoustical and thermal insulation, and one synthetic fiber insulation pad made of polypropylene (PP) and co-polyester (COPES). We determined the sound absorption coefficients of each of these fabrics as per ASTM E 1050. Additionally, we determined sound absorption coefficients of stacking velour fabrics with highloft insulation pads. The trunk lining systems have excellent sound absorption capabilities and can be used as soundproofing materials for automotives.
