What material is the meltblown cloth in the mask made of | JINHAOCHENG

In the past two years, the new crown virus is raging and the new crown epidemic is serious abroad. We ordinary people need to strictly protect themselves, pay attention to wearing masks (disposable masks, disposable medical masks or KN95 masks, N95 masks) and pay attention to social distancing, and target these selves. For knowledge of protection, you can refer to China's best practices for epidemic prevention. In this way, our health, including your family, friends, colleagues, etc., can stay away from the virus and enjoy life.


So, today, together with Jin Haocheng, the manufacturer of melt blown cloth (mask material), let’s learn about how the material of melt blown cloth in masks is made. 
Melt blown cloth is mainly made of polypropylene, and the fiber diameter can reach 1 to 5 microns. There are many voids, fluffy structure, and good anti-wrinkle ability. These ultra-fine fibers with unique capillary structure increase the number and surface area of ​​fibers per unit area, so that the melt blown cloth has good filtration, shielding, heat insulation and oil absorption. . It can be used in the fields of air, liquid filter materials, isolation materials, absorption materials, mask materials, thermal insulation materials, oil absorption materials and wipe cloths.


Everyone knows that medical masks contain a layer of melt blown cloth, so what material is the medical mask melt-blown cloth made of?

The melt blown cloth used in the mask is made of polypropylene material, and the melt blown cloth is also made of a polypropylene material called high-melt fat fiber. It is a kind of ultra-fine electrostatic fiber cloth, which can effectively use static electricity to absorb viruses, dust, Droplets, this is also an important reason why masks can filter viruses. Medical masks generally use a multi-layer structure, referred to as SMS structure: a single spunbond layer (S) on both sides. There is a single layer or multiple meltblown layers (M) in the middle. The best material for the meltblown layer is meltblown cloth. It is the main material for virus filtering of masks, and the middle M layer-meltblown non-woven fabric. In fact, these three layers are all non-woven fabrics, and the raw materials are all polypropylene, but the production process is different. Among them, the fiber diameter of the spun-bonded layer on the inner and outer sides is relatively thick, about 20 microns; the diameter of the melt blown fiber in the middle layer is only 2 microns, which is made of a polypropylene material called high-melt fat fiber. It is fragile and cannot be washed with water or sprayed with alcohol. Even if it is wet and dried, it will damage the fiber tissue and cause loopholes. If viruses enter through the loopholes, the mask loses its protective ability.

With the severe situation of the current epidemic situation, masks have become an indispensable item in our travel life. Let’s understand why masks can prevent viruses? First of all, the volume of coronavirus is 80~120nm, because it is usually attached to body fluids and sprayed out. , So it is generally larger than 0.1um (0.1 micron (um) = 100 nanometers (nm)). The meltblown cloth uses polypropylene as the main raw material, and the fiber diameter can reach 0.5-10um. If it is a virus attached to body fluids, it can Filtered out.
