Meltblown cloth equipment meltblown cloth process flow

1. Polymer feeding. The polymer is generally made into small spherical and granular slices, poured into a bucket or hopper, and input into the screw extruder.

2. Melt extrusion. At the feed end of the screw extruder, the polymer chips must be mixed with additives and other necessary raw materials. After being fully stirred and mixed, it enters the screw extruder and is heated to a melt. Finally, the melt is fed into the spinneret by the metering pump through the filter board. In the melt blown process, the general extruder also uses its shearing and thermal degradation to reduce the molecular weight of the polymer.
