The main raw material of melt blown cloth is polypropylene, which is an ultra-fine electrostatic fiber cloth with a 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. When droplets containing viruses come close to the meltblown cloth, they will also be electrostatically absorbed on the surface and cannot penetrate. Therefore, it is a necessary raw material for the production of filter masks.
Melt blown cloth, commonly known as the "heart" of the mask, is the filter layer in the middle of the mask, which can filter bacteria and prevent the spread of germs. Melt blown cloth is a kind of polypropylene with a high melt index as a material, a film made of many criss-cross fibers stacked in random directions. The fiber diameter ranges from 0.5 to 10 microns, and the fiber diameter is about 30 minutes of the hair. one.
Meltblown cloth is the M layer of protective masks. Spunmelt composite nonwovens include SMS, SMMS, SSMMS, etc. (where S stands for spunbond, M stands for meltblown). The application fields of spunmelt composite nonwovens have long gone far beyond the scope of the textile industry, and have been widely used in health, medical, industrial protection, environmental protection and other industries.
The main uses of meltblown cloth: filter material; medical and health materials; environmental protection materials; clothing materials; battery diaphragm materials; wiping materials.
The main uses of non-woven fabrics: non-woven fabrics for medical and sanitary use; non-woven fabrics for home decoration (wall coverings, tablecloths, bedsheets, bedspreads, etc.); non-woven fabrics for industrial use (filter materials, insulating materials, cement packaging bags, Geotextile, covering cloth, etc.); automobile industry (waste textile insulation thermal felt, shockproof felt, roof, seat cushion lining, carpet, door lining, automobile filter element, molded seat cushion), etc.
