Polyester fiber needled felt is nonwoven needle-punched process using fiber staggered, space distribution uniform fine fiber cloth, polyester staple fiber with polyester twisted yarn produced by needled felt hot rolling on the surface, singeing or coating.
Such as post-processing, make its surface smooth, not easy to be blocked by dust, the filter bag void fraction, permeability is good, use very extensive, strong resistance to chemical stability, not only can filter room temperature gas, and the filtering with acid and alkali corrosive gas, and can filter, oil filter, water is the working condition of normal temperature, solid-liquid separation in areas such as the ideal filter material.
