​Abstract

​Recycled fibers are normally second-hand in dissimilar applications and individual important function is noise reduction. Recycled fiber nonwoven composites, currently, are in greater demands in company and  their advantages such as low cost, biodegradability, acceptable mechanical & physical properties and so on. Noise reduction materials, biodegradable and environment pleasant nonwoven composites were produced using recycled cotton and polyester fibers.  Nine types of recycled nonwoven composites were developed using thermal bonding, adhesive bonding and compression molding methods. The blending ratio of polyester and cotton fibers is 60:40.  Noise reduction coefficient was measured by impedance tube method (ASTM E 1050). The recycled nonwoven composite physical properties are Thickness, specific airflow resistance, specific porosity, density, and air gap was determined for all the samples with respect to the ASTM standards. The results exposed that at the highest frequency of 4000 Hz. The NAC values of T WP, T CP, T CC/P, and C WP. C CP, C CC/P, TC CP, TC WP and TC CC/P are 0.39, 0.43, 0.5, 0.58, 0.6, 0.63, 0.68, 0.75 and 0.77.The performance of sample TC CC/P, C CP, TC CC/P shows equal values from 0 to 1000 Hz; this might be appropriate to the lower frequency, the small increase in thickness or fiber content of this nonwoven composites does not manipulate the noise reduction performance.

Keywords: Recycled fiber; Nonwoven composites; Compression molding; Physical properties; Noise reduction coefficient.
