The melting spray cloth is mainly made of polypropylene, and the fiber diameter can reach 1 ~ 5 micron. These ultrafine fibers with unique capillarity structure increase the number and surface area of fibers per unit area, so that the melt-jet cloth has good filtering, shielding, insulation and oil absorption properties. It can be used in air, liquid filtration materials, isolation materials, absorbing materials, mask materials, thermal insulation materials, oil-absorbing materials and wiping cloth and other fields.












Ordinary medical mask




As we all know, the medical mask contains a layer of molten spray, so what is the material of the medical mask molten spray?








The melting spray cloth used for masks is made of polypropylene, another polypropylene material called high-melting fat fiber. It is a kind of super-fine electrostatic fiber cloth, which can effectively absorb viruses, dust and droplets by using static electricity, which is also the important reason why masks can filter viruses.




Medical masks generally adopt a multi-layer structure, referred to as SMS structure: a single spunbonded layer (S) on both sides. The middle layer is monolayer or multilayer molten spray layer (M). The best material of molten spray layer is molten spray cloth. It is the main material for virus filtration of masks, and it is the middle M layer -- melt-spraying non-woven cloth.




In fact, these three layers are non-woven, the raw materials are polypropylene, but the production process is not the same. Among them, inside and outside on both sides of the spinning coating fiber diameter is thicker, in about 20 micron; The melt spray fiber in the middle layer is only 2 microns in diameter. It is made of a polypropylene material called high melt fat fiber. The melt spray cloth is fragile and cannot be washed or sprayed with alcohol.












N95 mask/respirator




With the severe situation of the current epidemic situation, masks have become an essential item in our travel and life. Let's understand why masks can prevent the virus. First of all, the volume of coronavirus is 80 ~ 120nm, which is generally larger than 0.1um (0.1 micron (um)=100 nanometers (nm) because it is generally attached to body fluids. The melting spray cloth is mainly made of polypropylene, and the fiber diameter can reach 0.5-10um. If the virus is attached to body fluids, it can be filtered out.








Through the above introduction, do you have a further understanding of the mask?
