Thermal - Acoustic Performance of 3D Spacer Fabrics and Their Possible Correlation

Original language description

Development of functional textile structures is important to improve noise attenuation of human life in automotives, residential and occupational environments. In this research, an attempt has been made to find the suitability of 3-dimensional (3D) knitted spacer fabrics for sound absorption. Hence, an experimental and analytical investigation on the sound absorption behavior of warp knitted spacer fabrics was conducted. Due to porous nature, interconnected pores, bulkier and 3D structure, the spacer fabrics have ability to attenuate more sound energy than the conventional materials. This research examined acoustic properties of spacer fabrics in relation to material parameters like thickness, density, surface structure and structural characteristics such as massivity, porosity, tortuosity and air flow resistivity. Sound absorption coefficient of the test samples was measured using the impedance tube method by ASTM E-1050 in the frequency range of 50 to 6400 Hz. The results showed that the acoustic insulation of spacer fabric improves with their thickness and massivity, reduction in its porosity, tortuous path and high air flow resistance. Advance statistical evaluation and two-way analysis of variance is used to analyze the significance of combined effect of various factors on air-flow resistivity and Noise reduction coefficient (NRC). These findings are important requirements for the designing of spacer fabrics for noise control in automobile upholstery, buildings, auditorium etc.
