The melt-blown nonwoven process uses high-speed hot air to draw a thin stream of polymer melt extruded from the spinneret of the die,thereby forming ultra-fine fibers and condensing on the curtain net or roller, and relying on itself It becomes a nonwoven fabric.
The melt blown cloth filter material is made up of polypropylene microfibres, which are randomly distributed and adhered together. The appearance of the material is white, flat and soft. The fineness of the material fiber is 0.5-1.0 μ M. the random distribution of the fiber provides more opportunities for thermal bonding between the fibers. Therefore, the melt blown gas filter material has a larger specific surface area and a higher porosity (≥ 75%). After high pressure electret filtration efficiency, the product has the characteristics of low resistance, high efficiency and high dust capacity
