Using recycled nonwovens as sound absorption materials are of great interest because of the increased nonwoven waste. In this study, needle-punched recycled polyester nonwoven was coated with polyethylene film, vinyl-based recycled polymer film and blends of these two materials in order to obtain new sound absorptive materials. Abrasion, tensile and acoustic features of the produced samples were measured and compared with the commercial PP-Fusing sample. It was seen that use of VBR polymer with polyethylene enhanced sound absorption properties of samples as well as their tensile strength and abrasion resistance performance. It is suggested to use needle-punched recycled polyester 'PET- 50% VBR- 50 %PE' sample for automobile rear trunk where acoustic insulation is required.
