1. The nature of masks is different

Disposable masks are made of two layers of 28 grams of non-woven fabric. Medical masks are mostly made of one or more layers of non-woven fabrics.

2, the production process is different

The main production processes of medical masks include meltblown, spunbond, hot air or needle punch, etc., which have the equivalent effect of resisting liquids, filtering particles and bacteria, and are a kind of medical protective textiles. The disposable three-layer mask is made of two layers of fiber non-woven fabric professionally used in medical and health, and a layer of filter melt blown cloth with more than 99% filtration and antibacterial protection in the middle is welded by ultrasonic.

3, different protective effects

Under the condition of air flow rate (85±2)L/min, the filtration efficiency of medical mask on the median aerodynamic diameter (0.24±0.06)μm sodium chloride aerosol is not less than 95%, which is in line with N95 (or FFP2) And above. It can block airborne infectious agents with a diameter of <5μm or close contact with infectious agents transmitted by droplets. Disposable masks cannot.

Disposable masks are very breathable; can filter toxic gases; can keep warm; can absorb water; can be waterproof; stretchable; will not be messy; feel very good and quite soft; compared to other masks, the texture is relatively light ; Very elastic, can be restored after stretching; the price is relatively low, suitable for mass production.
