Original title: Do you really understand the structure of KN95 mask? Do you really know the structure of KN95 mask? Medical masks and protective masks are non-woven materials,Quickly Delivery Disposable Protective Clothing, composed of directional or random fibers, generally multi-layer structure,Full Body Disposable Coverall, usually referred to as SMS structure (2 layers of S layer and 1 layer of M layer). At present, KN95 Face Mask with Five Layers ,3 Ply Disposable Protective Face Mask, the highest number of layers in China is 5, namely SMMMS (2 layers of S and 3 layers of M). S represents a Spunbond layer and M represents a barrier layer or a Meltblown layer M, both of which are composed of polypropylene (PP). Melt-blown nonwovens are used as the filter layer in the M layer. Because the fibers are randomly distributed and have complex three-dimensional pores, the M layer is composed of superfine fibers with large specific surface area and strong adsorption capacity for particles. The fibers of the melt-blown filter material are randomly distributed A large number of tiny pores are formed, and the pores are evenly distributed, the filtering resistance is small, and the filtering efficiency is high, so that the filtering performance of the non-woven medical protective mask is far superior to that of the traditional gauze mask. The SMS non-woven fabric is mainly made of polypropylene PP (with natural bacteriostasis and hydrophobicity),KN95 Mask with Fast Shipping, and the fiber diameter can reach 0.5-10 um. These superfine fibers with unique capillary structure increase the number and surface area of fibers per unit area, so that the melt-blown fabric has good air filtration and is a good mask material. Therefore, the laser marking surface is a non-woven fabric made of S-layer polypropylene. Return to Sohu to see more Responsible Editor:. zjyuan-group.com
