Meltblown Nonwoven Fabric

[Meltblown Nonwoven Fabric]

What is meltblown nonwoven?
Meltblown Nonwoven Fabric

The melt-blown nonwoven fabric is known as the "heart of the mask", disperses molten plastic through high-speed hot air, and spins the polymer melt through the spinneret of the ultra-fine nozzle, making it a high-performance polypropylene melt-blown filter material. Fibers are extremely thinner than other materials.

Electrostatic Electret, The Protection Are Additionally Upgraded

Without increasing the loading of uses, through electrostatic electret technology, the static electricity is absorbed in the melt-blown non-woven fiber, it can absorb viruses and bacteria that have penetrated through the surface layer, thereby improving the filtering performance of masks and other filtering products.

Features

It has ultra-fine fibers with shielding, filtering, oil absorption and thermal insulation properties. It has a wide range of fiber fineness and fiber diameters of up to 2 to 5 microns. These ultra-fine fibers can increase the number and surface area of fibers per unit area and can be used as mask materials , Air, liquid filter materials, thermal insulation materials, insulation materials, sound insulation materials, environmentally friendly oil-absorbing materials and wipe cloth and other fields.

The Middle Layer of The Mask Melt-Blown Non-Woven Fabric

The outermost layer of the mask is spunbonded non-woven fabric, which is highly breathable and water-repellent, and the first is to prevent the contamination of droplets; the middle layer is a melt-blown non-woven fabric, which mainly filters the virus, bacteria, dust and droplets in the air. The layer is made of water needle non-woven fabric, which absorbs sweat and grease, and the soft fiber allows users to have an excellent wearing experience.
