Abstract
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 performance of producing non-woven composite structures. For this aim, five different blend ratios of Typha/polypropylene including 0:100, 30:70, 50:50, 70:30, and 100:0 were prepared. The non-woven porosity, areal density, and sound absorption properties were studied. Impedance Tube Method, which provides the normal incidence sound absorption coefficient (SAC) of materials, was used for determining the acoustic properties of produced non-woven samples. The results of SACs of Typha non-woven revealed that the Typha fibers have good acoustic performance with normal incidence absorption coefficient greater than 0.6 from 500 to 4 kHz. Finally, according to the obtained results from this research, it is claimed that Typha natural fibers could be an acceptable choice for sound reduction applications.
