Polyester filter cloth
Material
Polyester felt are made of 100% filament polyester fiber.
For polyester fiber needled felt production normal temperature is used .Afterwards, it goes through non-woven needle-punched process using fiber staggered, equally distributed uniform fine fiber cloth. The Polyester staple fiber with polyester twisted yarn is produced. It then receives the following treatments like heating, singeing or coating on the surface as post-production process, make its surface level smooth. So that it cannot get blocked by dust easily.
Polyester filter cloth
Polyester filter cloth is used in selected filtration applications. Chemical compatibility, temperature suitability and filtration performance depend on the media construction and actual operating conditions. Confirm suitability for the process before selection.
Share the required filter dimensions, process medium and operating conditions for product selection.
Confirm media construction, finish and filtration requirements against the selected product specification.
Contact SFFILTECH for product information, available documentation and quotation details.
Feature
Application
Polyester filter bag widely used in mine, limestone, cement, iron and steel industries, alumina delivery, electrolytic aluminum, non-ferrous metal production, wood processing, food processing and pharmacy industry.
SFFILTECH supplies polyester filter cloth. Product suitability and performance should be confirmed for the selected configuration and actual operating conditions.
Advantage
Breaking Elongation is less than 20% for MD and 40% for CMD, low dry shrinkage, can work well in the 130℃. The material is cheaper than other material, so widely used in a lot of bag house system.
Surface finish, media construction, bag dimensions and dust loading influence operating resistance and cleaning behaviour.
Filtration efficiency, pressure drop and energy use depend on the selected media, airflow, dust characteristics and system operation.
It's usage in air blow dust precipitator, at the same pressure, the same air volume of air dust. Due to the weaving techniques used it has a higher breathing ability rate compared to other filter bag materials. Therefore, the filter material achieves high filtration precision. Our company has done a lot of research on how to improve the porosity, the degree of the surface smoothness, reduction of dust adhesion, reduction of the running resistance. Our factory developed new resinification and weaving techniques to produce smooth surface finishing needled filter felt bag. With 50% higher porosity than that of other filter material and smoother surface for pressure stability.
