  • the invention belongs to the technical field of masks, and particularly relates to a replaceable protective mask and a manufacturing process thereof.
  • Masks are an important line of defense to prevent respiratory infectious diseases. They can not only prevent patients from spraying droplets, reduce the amount and speed of droplets, but also block virus-containing droplet nuclei to protect the wearer from the risk of inhalation. With the development of the novel coronavirus-infected pneumonia epidemic, whether it is an ordinary family, an individual, or a hospital or community hospital in the front line of the epidemic, the demand for masks is almost unlimited.
  • Masks are generally composed of the following parts: main filter material, nose clip and hanging ears, etc.
  • the main filter material generally has three layers, the inner and outer layers are non-woven fabrics, and the middle filter layer is melt blown cloth.
  • melt blown cloth is very important. It is worth noting that as an important raw material for medical surgical masks and N95 masks, melt blown cloth is different in the amount of the two.
  • Medical surgical masks are generally SMS structure (two spunbond layers and one melt blown layer), which can filter N95 masks with 95% fine particles sometimes need to be made of SMMMS non-woven fabric (three-layer melt blown layer), and the amount of melt blown cloth is much higher than that of ordinary masks.
