The melted molecules are squeezed into the high-speed hot airflow through the extruder. And then the polymer melt is spun out through the spinneret of the ultra-fine nozzle to form ultra-fine fibers, which are blown vertically onto the collector screen and accumulated into ultra-fine fibers.
The ultra-fine fibers of the meltblown non-woven fabrics can absorb static electricity in the meltblown non-woven fabrics through the electrostatic electret technology, so that it can absorb viruses and bacteria that have penetrated the surface. It is very suitable for composites that require filtration, shielding, heat insulation, and oil absorption. For example, materials separately for masks , air/ liquid filter, thermal insulation, isolation, sound insulation, environmentally friendly oil-absorbing and wipe papers.
