Fabrics Q&A

The reason is that it uses physical principles to isolate air pollutants and is more durable (the non-woven material used in traditional masks needs to rely on electrostatic adsorption of particles due to its l…

The dust-blocking principle of traditional non-woven masks is electrostatic adsorption, and the interception effect is relatively poor. The adsorbed particles can easily lead to a decrease in breathability and …

The ptfe nanomask filter membrane is mainly because the fiber diameter of the material it uses is smaller than that of traditional materials (the fiber diameter of the non-woven material used in traditional mas…

The respiratory impedance of the ptfe mask filter material is only 60-70pa, and the ordinary melt-blown non-woven mask is as high as 120-250pa. In comparison, the breathability of the film mask is already very …

Because the high-efficiency filter material needs to effectively intercept dust particles without causing excessive resistance to the air flow. In order to achieve good filtration efficiency, the number of fibe…

The raw materials of masks are mainly composed of spunbond nonwoven materials, meltblown nonwoven materials, air-through nonwovens, needle-punched nonwoven materials, as well as accessories such as ear straps a…

During World War II, in order to further establish its world dominance, American capitalism began to conduct research on radioactive substances, but they needed to develop an item to protect against all harmful…
