Problems solved by technology

[0002] Traditional mask protection is to prevent bacteria and viruses in the air from attaching particles to the human respiratory tract. The principle is that the melt-blown cloth is electrostatically adsorbed. As the moisture exhaled by the human body increases, the static electricity on the non-woven fabric will gradually disappear, thus losing the adsorption function. Therefore, the effective use time is not long, and it cannot be washed and disinfected. It can only be used as a disposable mask with a short lifespan.
With the spread of the new crown pneumonia epidemic around the world, the supply of traditional protective masks is in short supply, and most of them have a short lifespan and cannot be recycled

Abstract

The invention relates to a mask, in particular to a recyclable protective mask. The protective mask comprises a mask body covering the mouth and the nose of a wearer and ear hanging parts. The mask body sequentially comprises an inner layer, a middle layer and a surface layer from inside to outside. The inner layer is made of an all-cotton material; the surface layer is made of an all-cotton, cotton-linen or polyester-cotton material; the middle layer is made of a microporous material of expanded high molecular weight tetrafluoroethylene copolymer dispersion resin, wherein the pore diameter ofthe microporous material is less than 75nm. According to the protective mask disclosed by the invention, the cover is made of three layers of materials and have the improved air permeability and thecomfort degree are superior to those of a non-woven fabric material; no damp discomfort is caused after long-time wearing; the filtering performance on fine particles with the particle size of 75 nanometers exceeds 95 percent; the mask is suitable for protection of theCOVID-19 pathogen viruses, the filtering effect on PM2.5 reaches up to 99.9 percent, and water-based and oil-based particles, bloodand the like can be efficiently isolated, so that a respiratory system is comprehensively protected.
