It has been known that woven fabrics and nonwoven fabrics exhibit absorption capability. Despite this, both have different characteristics in absorption. The absorption of woven fabrics occurs due to resonance system which has a narrow absorption bandwidth but it is tunable for low frequency absorption. Meanwhile, that of nonwoven fabrics is present due to mainly visco-thermal effect of porous media so that the wide absorption bandwidth can be obtained at mid-high frequency. This works is focused to investigate the possibility to combine features of each fabrics in order to have a better performance of textile-based absorber. Experimental works on some configurations of combined woven fabrics and non-woven fabrics are conducted. It is found that some absorption enhancements are observed compared to original performance of each material. Hence, both materials are complementary to produce a better performance in overall. However, such a combination should be realized with a great care as absorption performance at mid-high frequency can be deteriorated or lead to poor results.
