Polyester needle felt is used nonwoven needle punched process using fiber staggered, gap distribution of superfine fiber cloth, polyester staple fiber and polyester have twist yarn produced by the needle punched felt surface after hot rolling, singeing or coating treatment, so that its surface smooth smooth, is not easy to be blocked by dust, the filter material porosity, better air permeability. use a very wide, strong resistance to chemical stability, can not only filter gas at room temperature,and filters containing acid and alkali corrosive gas, and water filter. Oil filter is normal temperature condition. Liquid solid separation and other fields of ideal filtermaterial.
