The third-generation water electret production line designed and produced by Shanghai Spuntex Machinery Co., Ltd. uses a specially treated aqueous solution to be sprayed from the spray device at a designed pressure.  The mist droplets are under the dual action of the spray force and the suction device.  , Passing through the fiber web with curved channels at a certain high speed, water mist and gas fluid fully rub the fibers, and the electric charge generated by the friction electrification is deposited inside the fibers of the material.  Greatly improve filtration efficiency, significantly reduce filtration resistance, and maintain long-term filtration efficiency, which can meet high-end filtration requirements such as American standard ASTMF2100-19, European standard EN14683-2019, EN149 (FFP1/FFP2/FFP3). 

    Shanghai Spuntex Machinery Co., Ltd. can produce water electret production line, which meets European standards P3/P2/P1 meltblown cloth;  meets American standards N (non-oily)/R (oily)/P (mixed type) The series of melt blown cloth can reach up to N100/R100/P100 respectively;  in addition, the company can provide melt blown process services (especially BFE99 and N99) that improve and optimize the company’s existing melt blown lines;  provide high-end mask products Design guidance service.
