Identification Of Mask Meltblown Cloth Is Actually Very Simple!
Polypropylene is the main raw material of melt blown cloth, and the diameter of fiber can reach 0.5-10 μ m. 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, thermal insulation and oil absorption, It can be used in air, liquid filter material, isolation material, absorbing material, mask material, heat preservation material and wiping cloth
The filter materials of the common dust masks on the market are melt blown non-woven materials. The materials are mostly polypropylene, which is commonly called PP melt blown cloth. It is a kind of superfine electrostatic fiber cloth, which can catch dust. After the dust is caught by the superfine electrostatic fiber cloth, it is very difficult to get rid of it due to cleaning. Moreover, washing with water will also damage the dust collection capacity of static electricity. Therefore, the non-woven cloth mask can not be cleaned and needs to be discarded after use.
In addition to meltblown cloth, superfine spunlace should be the most effective, but the price of superfine spunlace is too high. And the thickness gram weight, are far more than the general thickness to heavy. Therefore, it can be negated from the cost
