For a good protective mask filter material, should have the following three conditions, one is in the mask and the user's face close to the case of high filtration efficiency, two is the respiratory resistance is small, three is the user feel comfortable. Dust mask filter material has a variety of materials, including ordinary fabrics, animal hair, non-woven fabrics. In the national standard is very popular is a kind of activated carbon felt material.
The structure of the gauze mask has poor adhesion to the human face. Many fine particles that are extremely harmful to us will enter the respiratory tract to the lungs through the gap between the mask and the face. Its filter material is generally some mechanical fabrics. To achieve high dust blocking efficiency, the method is to increase the thickness, and the negative effect of increasing the thickness is to make users feel great respiratory resistance and uncomfortable. The non-woven fabric after electrostatic treatment can not only block large dust particles, but also the electrostatic charge attached to its surface can adsorb fine dust by electrostatic attraction, achieving high dust resistance efficiency. The thickness of the filter material is very thin, which greatly reduces the user's breathing resistance and feels comfortable, thus achieving the three necessary conditions for the good filter material we mentioned earlier. With a good filter material, with the scientific design of the mask structure, it constitutes a high-efficiency and high-quality mask.
