Taking polypropylene granules as raw material, after melting at high temperature, the polymer is extruded and stretched to form continuous filaments, and then the filaments are laid into a web by airflow traction, and the web is then processed into meltblown nonwoven fabric by thermal bonding reinforcement method.

Polymers (polypropylene + return material) - large screw high temperature melt extrusion - filter - metering pump (quantitative conveying) - spinning (spinning inlet up and down stretch suction) - cooling - airflow traction - net curtain into the network - upper and lower pressure roller (pre-reinforcement) - mill hot rolling (reinforcement) - winding - rewinding slitting - weighing and packaging - finished products into the warehouse
In addition to mask materials, they can also be used in fields such as filtering materials for air or liquids, isolation materials, absorbing materials, warming materials, oil-absorbing materials, and wiping cloths.
Meltblown nonwovens are used to replace traditional textile products with spunbond nonwovens compounded for mask fabrics.
Meltblown nonwoven fabric is the best material for making thermal insulation garments because of its particularly fine fiber diameter, small pore size, high void rate, soft hand feel, very good wind resistance, good air permeability, and very lightweight.
The fiber diameter of meltblown cloth can reach 1-2μm, and the arrangement is randomly distributed, with a certain degree of heterogeneity, and this structure makes it have a larger specific surface area, a smaller pore size. It is possible to make very high-quality filtration materials. It is mainly used in air filtration, water filtration, oil filtration, oil-water separation, and many other fields.
As the meltblown cloth is mainly made of PP raw material, it has good oil-absorbing performance due to the fact that PP hardly absorbs but has good lipophilicity, as well as meltblown cloth, has high porosity and large specific surface area.
Sound insulation materials
Meltblown nonwovens are used for sound insulation in automobiles, homes, and ultra-quiet rooms because of their inherent many voids that effectively absorb the transmission of sound waves.
Industrial and household wipes
Meltblown nonwovens are used in industrial and household wipes because of their strong stain removal power, soft feel, and lack of damage to the surface being wiped.
