Electret meltblown cloth
Electric electret process and principle: the use of high-speed hot air to the die spinnerets extruded polymer melt thin stream to draw, thereby forming microfibers and condensed on the condensation curtain or drum, through the electrostatic electret equipment high-voltage discharge, the charge is attached to the meltblown non-woven fabric. Particles are captured by the dual action of mechanical blocking and electrostatic adsorption.

PLA meltblown cloth
PLA meltblown cloth process and principle: polylactic acid (PLA) mostly uses corn starch fermentation to obtain lactic acid and then polymerized into polylactic acid, PLA meltblown filtration performance is excellent, high efficiency and low resistance, not only has the protective performance of PP meltblown performance, but also can achieve green degradability.

Water electret meltblown cloth
Water electret process principle: the prepared pure water is transported to the spunlace device at high pressure through the high-pressure water pump, and the meltblown cloth is sprayed by the fan-shaped nozzle, and the two friction to generate static electricity.

Electric electret VS water electret
Electric electret: the standing current mostly stays on the surface of the meltblown cloth, the filtration effect cannot reach the peak, and the surface static electricity is easy to decay during storage. It is mostly used for disposable flat masks, medical surgery and other masks.
Hydro charge : the electret penetrates into the inner structure of the melt blown cloth, the static electricity is saturated, the electret is durable, not easy to decline, high efficiency and low resistance, and can pass the oil and salt testing, but the production cost is high. Mainly used for kf94, kn95, FFP2, ffp3, kn100 and other masks.
