N95 mask non woven fabric production machine line

At present, the supply of melt blown nonwoven fabric  is in short supply; there are high technical barriers in the production of melt blown fabric , and the requirements for equipment and technology are very high.But with the experience and technology of our engineer, we  overcome all these difficulties, and finally the machines are researched and the qualified non woven fabric is produced

Generally, the mask adopts multi-layer structure, which is called SMS structure for short: single-layer spunbond layer (s) on both sides and single-layer or multi-layer melt blown layer (m) in the middle. The best material of melt blown layer is melt blown cloth.

The main material that brings virus filtering effect to the mask is the m layer in the middle - melt blown non-woven fabric.

Melt blown cloth is made of polypropylene material PP called high melt finger fiber. It is a kind of ultra-fine electrostatic fiber cloth. It can effectively use electrostatic to absorb virus dust and droplets, which is also an important reason why mask can filter virus. (if you don't know whether your mask is anti-virus or not, it depends on whether there is a melt blown cloth in the mask.)

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 0.5-5.0 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
