Abstract

The invention discloses a novel efficient and low-resistance compound antibacterial air filtering material. The novel efficient and low-resistance compound antibacterial air filtering material comprises a PET/PA (Polyethylene Terephthalate/Polyamide) double-component filament fiber bottom layer and an antibacterial master batch/PP (Polypropylene) fiber surface layer, wherein the two layers are melt-blown and self-adhered by double nozzles; the tensile strength of fibers of the bottom layer is high and components of antibacterial master batches of the surface layer are special; the filtering material can be used for firmly adsorbing micro-particles, bacteria and viruses, which have negative charges, in a filtering material so that the bacteria and the viruses lose the activity and the sterilization effect is realized; and the 8-hour inhibition rate on colon bacillus and staphylococcus aureus is more than 99.5%.

Description

technical field [0001] The invention relates to the field of air filter materials, in particular to a novel high-efficiency, low-resistance composite antibacterial air filter material. Background technique [0002] The process of global industrialization has brought great damage to the earth environment on which human beings depend, and the concept of "healthy, low-carbon, and environmentally friendly" life has penetrated into all aspects of people's lives. Breathing fresh and clean air is the basic requirement of human beings, and it is the responsibility of the air purification technology industry to prevent and control air pollution and viruses. Among the many air purification technologies, the most widely used and most mature is the air filter, so obtaining the ideal filter material with high filtration efficiency has become the core technology. At present, conventional filter materials can only effectively keep dust and bacteria out and accumulate on the filter materia...
