1) PET dust bag id made of PET fiber by needling craft
2) large porosity, high air-permeability, long working life, low price
1) PET dust bag is made of PET staple fiber by needling process.
2) The surface of this product is neat and smooth after certain finish treatment such as heat setting, singeing,
calendaring or coating.
3) is an ideal filter medium under normal temperature in areas of solid-liquid separation and gas-solid separation and widely used in steel industry, non-ferrous metal, chemistry industry, cement and foodstuff etc.
