25Gsm 50Gsm 60Gsm mask material bfe99 bfe95 meltblown nonwoven fabric/melt blown fabric filter cloth
Melt-blown non-woven fabric is a kind of ultrafine fiber non-woven material made by melt-blown process, raw material is food grade PP, fibre diameter can be 0.5um-2um. The product is treated with special electrostatic, characteristics of high efficiency and low resistance, comfortable and easy to adorn. Can effectively filtration and adsorption of microorganisms, viruses and extremely dust.
Medical grade mask filter can meet with Europe standard EN14638:2003 requirements, the bacterial filtration efficiency(BFE) is over 99%.
Industry grade mask filter can meet with Europe standard EN149:2001 FFP1/FFP2/FFP3 requirements, and USA standard NIOSH 42 CFE-84 requirement such as N95/N99/N100 etc.
Non woven fabric
High quality: Stable Uniformity, Adequate Weight; Soft Feeling, Eco Friendly, Recycleable, Breathable; Good Strength and Elongation.
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;
13. Environmental friendly, non-polluting, polypropylene chemical structure is not strong, the molecular chain structure is easy to break, thus effectively and quickly into the degradation process, and the relevant non-woven shopping bags can be used more than 10 times, and the pollution degree of waste plastic bags only 10%.
