Melt-blown non-woven composite filter material is made of polypropylene ultrafine fibers that are randomly distributed and bonded together. The appearance is white, smooth, and soft. The fiber fineness of the material is 0.5-1.0 μm. The random distribution of the fibers provides an excellent space between the fibers. More opportunities for thermal bonding, thus giving the melted air filter material a larger specific surface area and higher porosity (≥75%).
After high-pressure electret filtration efficiency, the product has the characteristics of low resistance, high efficiency, and high dust holding capacity.
At present, melt-blown non-woven composite filter materials can be used as filter media, which can significantly improve filtration efficiency.
There is also data showing that because the fibers in nanoscale melt-blown nonwovens are thinner, melt-blown fabrics with a lighter weight can be combined with spunbond composites, which can still withstand the pressure of the same water head, and the SMS made of them can Such products can reduce the proportion of melt-blown fibers.
