The main purpose of meltblown cloth

Meltblown non-woven fabric is the heart of the mask for external anesthesia surgical mask N95. It is a filter layer in the middle of the mask. It has good filterability, shielding, heat insulation and oil absorption. It is an important raw material for the production of masks. Spinning cloth has the advantages of good uniformity, high filtration efficiency and strong barrier ability. It is mainly used in medical equipment, filter materials, clothing materials, etc.

Meltblown process principle
The melt-blown nonwoven process uses high-speed hot air to draw a thin stream of polymer solution extruded from the die spinneret, thereby forming ultra-fine fibers and condensing on the curtain net or roller, and relying on self-adhesion. Nonwovens.

Production process of meltblown non-woven fabric
Polymer preparation → Melt extrusion → Metering pump → Melt die assembly → Thin-flow drawing of solution → Fiber cooling → Auxiliary net → Reinforced cloth
