White BFE95& BFE95 Melt-blown masks filter material for disposable face mask

Melt-blown cloth is a high-speed hot air flow that draws a thin stream of polymer melt extruded from the nozzle hole of the die, thereby forming ultra-fine fibers and collecting them on the condensed screen or roller, while bonding themselves Meltblown nonwoven fabric.

Melt-blown cloth is a high-speed hot air flow that draws a thin stream of polymer melt extruded from the nozzle hole of the die, thereby forming ultra-fine fibers and collecting them on the condensed screen or roller, while bonding themselves Meltblown nonwoven fabric.

The production process of melt-blown cloth is mainly as follows:

1. Melt preparation

2. Filter

3. Measurement

4. Melt is extruded from the spinneret

5. Melt flow drafting and cooling

6. Netting
