The traditional meltblown cloth uses corona electret, its surface electret is obvious, but the filtering effect can not reach the peak and storage will decrease with time, the electrostatic attenuation of the material surface is obvious;
The water tret cloth is a high pressure water pump to prepare pure water to spire device, by fan-shaped nozzle to spray the melt-blast cloth, friction between the two resulting in static electricity;
The performance of the water electret melt-blast cloth is static saturation.
The water electret charging mode can be used for oily and salt detection, which can effectively solve the problem that the melt-blast cloth electret filtering efficiency is reduced after storage by the elevator in the mask industry.
