Problems solved by technology

[0007] Currently commonly used air filter materials include non-woven fabrics, activated carbon, foam, etc. For non-woven fabrics, the air resistance is directly proportional to the filtration efficiency. The greater the air resistance, the higher the filtration efficiency. The smaller it is, the lower its filtration efficiency

Abstract

The invention relates to a breath protector with high-filter fiber implant filter material, especially providing one breath protector with fiber implanted foam filter material, wherein said filter material uses the gas gel theory, to improve the filer efficiency without affecting the penetration; and the foam material, via planted with fiber, increase itself surface via different fiber lengths and contents, to improve the filter efficiency.

Description

technical field [0001] The present invention relates to a respiratory protection device with a high filterability fiber implanted filter material, especially a respiratory protection device with a fiber implanted foam filter material. In the case of affecting its air permeability, it can effectively improve its filtration efficiency. [0002] After the foam material is specially planted with fibers, its surface area can be increased through different fiber fineness, length and content, which can specifically improve its filtration efficiency, but does not affect its air permeability. [0003] According to the principle of aerosol, it can be roughly divided into five effects, three of which are better in filtering larger suspended particles: (1) Interception, which means that impurities are directly intercepted by the fibers of the filter material. (2) Inertial Impaction (3) Gravitational Settling between masses, such as universal gravitation. [0004] The other two effects a...
