By electret treatment, the melt-blown nonwovens have better adsorption effect on viruses, bacteria and particulate matter in the air than ordinary melt-blown nonwovens, effectively block the spread of viruses, bacteria and other harmful substances in the air, and have better protection performance.2. The melt-blown nonwoven products have been tested by qualified third-party inspection institutions, and the test results show that the product performance meets the key performance index requirements of raw materials in the national mask standards.3. Melt-blown nonwoven products can be used to produce N95 protective masks, medical surgical masks, disposable medical masks, ordinary civilian masks and other epidemic protection products.

The advantages of medical non-woven fabrics are:

1. strong ventilation, medical non-woven fabric from 100% fiber composition porous, good ventilation.
2. good filtration, polypropylene chips without water absorption, moisture content is zero, easy to filter;
3. good heat preservation.
4. Non-toxic, non-irritating, the product is produced with FDA food-grade raw materials, without other chemical components, stable performance, non-toxic, odor-free, non-irritating skin;
5. good waterproof.
6. good flexibility, by polypropylene spinning directly into a network of thermal
bonding, product strength is better than ordinary staple fiber products, strength without direction, longitudinal and transverse strength is similar;
7. it is not untidy, elastic, recoverable, and has no fabric directivity.
8. feel good, soft, composed of fine fibers (2-3D) light spot-like hot-melt bonding molding, finished products with moderate softness, comfortable;
9. light, with polypropylene resin as the main raw material, the specific gravity is only 0.9, only three-fifths of cotton, fluffy, feel good;
10. compared with textile cloth, the production is high and the production speed is fast.
11. the price is low and can be produced in large quantities.
12. Antibacterial, chemical resistance, polypropylene is a chemical passive substance, not moth, and can isolate the presence of bacteria and insects in the liquid erosion; antibacterial, alkali corrosion, the finished product does not affect the intensity of erosion;
