Meltblown nonwoven materials have the advantages of fine fibers, many pores and small pore size. Therefore, in daily life, melt blown nonwoven fabrics are often used as filter materials.

Application: Gas filtration: medical masks, indoor air conditioner filter materials.(melt-blown non woven supplier)Liquid filtration: beverage filtration, oil filtration. In order to improve the filtration effect, the fiber fineness can be reduced and the density of the filter material can be increased, but the filtration resistance is significantly increased.

Therefore, the melt-blown nonwoven material(melt-blown non woven factory) is electrostatically charged, and the filtration effect can be improved by the electrostatic effect, that is, the electret treatment is performed. The electret-processed melt-blown nonwoven fabric has the advantages of high filtration efficiency and low filtration resistance due to its long-lasting static electricity, which can collect fine dust by electrostatic effect. Polypropylene(polypropylene non woven on sales) has a high electrical resistivity and a large charge-injecting capacity, making it an ideal material for the manufacture of electret fibers.

Experiments have shown that the filtration efficiency of the polypropylene melt-blown nonwoven fabric after standing for a long time in the natural state remains unchanged.
