_Polyester Needle Felt

_The filter cloths for dust-removing cloth bags are made of (the conductive fiber yarn is incorporated into the warp yarn of the base fabric for the production of needle-punched felt or the conductive fiber and other conductive materials are mixed into the chemical fiber) Performance, used in flour dust, chemical dust, coal dust and other industries that may explode in the event of electrostatic discharge. It is currently the ideal choice for explosion-proof dust collection.

     After the concentration of industrial dust reaches _ degree (that is, explosion), if it encounters static discharge sparks or external ignition and other factors, it is easy to cause explosion and fire. For example, flour dust, chemical dust, coal dust, etc. may explode in case of electrostatic discharge. In the field of bag-type dust removal, if the dust needs to be collected with a cloth bag, the filter material used to make the dust-removing cloth bag is required to have _ performance. Our company absorbs and digests foreign technology, and develops and produces _ Needle Filtration Felt according to the domestic blast furnace gas coal mill dust collection and cement plant coal mill dust collection and other industry needs.

     In addition to the process of producing ordinary needle-punched felts, the production of antistatic filter cloth also requires that conductive fibers or stainless steel conductive materials be mixed into the chemical fibers of the needle-punched felts to produce antistatic needle-punched felts with more excellent antistatic properties.
