PP Meltblown Nonwoven Fabric Spinneret Extruding Mould Die

Melt-blown spinning is to blow a molten polymer through a high-temperature high-speed gas to refine the polymer into a filament to form a nonwoven fabric.

Meltblown principle: the melting polypropylene, driven by pressure and air flow, forms tiny fibers, which are then sprayed onto the object and bonded into cloth. The spinneret is the core part of the melt blown fabric equipment. There are many spinnerets on the die for the melt to pass through. Its production and processing are very important, which is related to the production efficiency and quality of the melt blown fabrics. There are more than 300 ~ 2000 micropores in different die sizes. According to the different application level of the melt blown fabrics, the micropore diameter also has the size difference. 

For N95 mask which is in short supply at present, its aperture should be 0.2mm or less.

Conventional models 600MM, 800MM, 1200MM can also be customized in different widths according to customer requirements to meet different production line configurations and process requirements.
