What material is melt blown cloth made of？
The main raw material of melt blown cloth is polypropylene, which is a kind of ultra-fine electrostatic fiber cloth with fiber diameter of about 2 microns. Its diameter is only one tenth of the diameter of the outer fiber of the mask, which can effectively capture dust. After the droplets containing virus are close to the melt blown cloth, they will also be adsorbed on the surface by static electricity and cannot be penetrated. Therefore, it is a necessary raw material for the production of filter masks.
Melt blown cloth, commonly known as the "heart" of mask, is the filter layer in the middle of mask, which can filter bacteria and prevent the spread of bacteria. Melt blown cloth is a film made of polypropylene with high melt index and many crisscross fibers stacked in random directions. The fiber diameter ranges from 0.5 to 10 microns, and its fiber diameter is about one thirtieth of that of hair.
Difference between melt blown fabric and non-woven fabric
Main uses of melt blown cloth: filter material; Medical and health materials; Environmental protection materials; Clothing materials; Battery diaphragm material; Wipe the material.
Main uses of non-woven fabrics: medical and sanitary non-woven fabrics; Non woven fabrics for home decoration (wall cloth, tablecloth, bedspread, bedspread, etc.); Industrial non-woven fabrics (filter materials, insulating materials, cement packaging bags, geotextiles, coated fabrics, etc.); Automobile industry (waste textile isolation thermal felt, shockproof felt, roof, cushion lining, carpet, door lining, automobile filter element, formed cushion), etc.
