Meltblown special manufacturing process

2021/04/30

Melt the meltblown material into a liquid, then squeeze it with a rotating wheel, and then collect it with a wooden stick


Then the molten polymer is forced to be extruded through a small and narrow nozzle. The molten high-temperature polypropylene (230-390) is stretched or compressed by the impact of high-speed airflow (480-800km/h) on both sides of the nozzle. The molten polymer is then solidified and wound on the conveyor into a discontinuous ultra-fine fiber network arranged randomly.


Finally, the melt-blown is compressed and formed between the heating rollers
