How to judge the authenticity of the mask meltblown cloth?


    Meltblown cloth is mainly made of polypropylene. There are many voids, the structure is fluffy, and the ability to resist wrinkles is good. Has a good filterability. Good shielding, thermal insulation and oil absorption.

    Two-layer masks are very inferior. Medical masks must have three layers. Both sides of medical masks are usually spunbond, and the middle is meltblown fabric. A good meltblown cloth is heavy enough. It looks white rather than transparent. It looks a bit like paper. The thinner the meltblown cloth, the worse the protective effect. The melt blown layer will melt when it encounters fire and will not burn. The melt blown layer has an electrostatic adsorption effect. You can use these to distinguish between true and false.
