Meltblown fabric can be called the "heart" of medical surgical masks and N95 masks.
Medical surgical masks and N95 masks generally adopt a multi-layer structure, abbreviated as SMS structure: the inner and outer sides are single-layer spunbond layers (S); The middle layer is the melt blown layer (M), which is generally divided into a single layer or multiple layers.
The meltblown non-woven fabric filter material is made of randomly distributed polypropylene ultrafine fibers bonded together, with a white, flat, and soft appearance. The fiber fineness of the material is 0.5-1.0 μ m. The random distribution of fibers provides more opportunities for thermal bonding between fibers, thus making the melt-blown gas filter material have a larger specific surface area and higher porosity (≥ 75%). Through high-pressure electrostatic filtration efficiency, the product has the characteristics of low resistance, high efficiency, and high dust holding capacity.
