Study on the sound absorption of jute fabrics: effects of woven factors and multilayer structures

Abstract

As porous materials, textiles have been widely used in noise reduction and control engineering due to the advantages of lightweight and easy processing. In this work, the effects of structural factors and physical properties of woven jute fabrics on sound absorption were investigated. Woven jute fabrics with different warp and weft density, thickness, areal weight, and bulk density are employed for acoustical impedance tube measurement, and the warp and weft flexural rigidity, and air permeability of woven jute fabric were measured. The relationship between structural characteristics and sound absorption properties was studied, which has provided good reference for the design of fabric texture. Furthermore, multilayered structure was also constructed by facile plying-up method, followed by the evaluation on the effects of various layering configuration, and then for improved sound absorption. This investigation has mainly focused on woven factors and physical properties, which is benefit to the fabrication of woven jute fabrics with optimal structural details for enhanced sound absorption.
