Studies on fibres used pandas in non-woven products. Objective is to experiment with forming non-woven from polyester fibers, enough to keep the fibers in the process of Needle punching test the sound absorbing properties and physical properties of non-woven fabric. Passengers. how to put fiber non-woven fabric optimization comes down and increase revenue. By taking enough fiber, polyester fiber with a nun in a ratio of 100:0, 90:10, 80:20, 60:40, 70:30 and 50:50 via the open fibers and fibers, and then pass into a carding the fiber, the fiber sheet (Web) after it mounted via mechanical process using a needle (Needle punching) at a speed of 2.5 ft/min and 5 ft/min speed. Perform the tests sound absorption frequency 150 – 4000 Hz and physical properties Testing found that the non-woven cloth from the fibers enough polyester fiber with a nun in a 60:40 ratio, at a speed of 5 ft/min with a maximum sound absorption properties.
