Wearing a non woven face mask is the basic means of defending against the new coronavirus. Masks generally have three layers, from the outside to the inside are the waterproof layer, the filter layer, and the comfort layer. The waterproof layer is a layer of polypropylene spunbond non-woven fabric, which can effectively blocks the visible objects such as droplets. The filter layer is a layer of melt-blown non-woven fabric, which has high strength and strong filtering ability, and has excellent capture ability to micro and nano particles such as fine dust and bacteria in the air, which can effectively prevent the penetration of bacteria and liquid, but can be breathable; it can prevent cross-infection and reduce the shedding of dust and hair. The comfort layer is also polypropylene spunbond non-woven fabric, which makes the skin dry and comfortable.
