Sound absorption characteristics of needle-punched sustainable Typha /polypropylene non-woven

Natural fibers are the acoustical sustainable materials used in blends with polypropylene as carded needle-punched non-woven for the automobile industry. Among the variety of natural fibers, studying the noise-absorptive properties of a novelty introduced fiber called Leafiran extracted from the Typha Australis plant has been aimed in this paper. Typha natural fibers were blended with polypropylene fibers in order to investigate the effect of this newly known natural fiber on the acoustic perfor
