More Information
Summary:A complex functional fiber structure is provided to improve a sound-absorbing property by forming a pile layer including cloth made of fiber and an air layer and adding sound absorption of the cloth and sound absorption of the file structure and to have a superior acoustic absorptivity at a low frequency. A complex functional fiber structure contains an intermediate pile four-layer(200) formed on a top of a lower part material layer(100) with piles. A thickness of the structure is 1-50mm. A density of the piles of the intermediate file four-layer is 20-80 CPI. The intermediate file four-layer and the lower part material layer improve a sound-absorbing property. A top material layer(300) is formed on a top of the intermediate file four-layer. Yarn comprising a lower part material layer is made of string with a low melting point in order to improve an adhesive property with a sound absorption board.
