ptfe waterproof and breathable membrane is widely used in air filtration, liquid filtration, industrial dust removal, and clothing fabrics. The following are the What the editor mainly introduces to you is its use in clothing.
ptfe is also called polytetrafluoroethylene. The diameter of polytetrafluoroethylene micropores varies from 0.1 to 0.5 microns, while water vapor molecules The diameter of pores is 0.0004 microns, the diameter of light mist in rainwater is 20 microns, and the diameter of drizzle is already as high as 400 microns. The pore diameter is between water vapor and rainwater. The diameter of micropores is smaller than that of light mist in water molecules and much larger than that of water molecules. The diameter of the vapor molecules allows water vapor to pass through but water droplets cannot pass through. This microporous structure can be used to achieve good waterproof and breathable functions, so it is a good waterproof and breathable material. In addition, because the holes are very small and arranged in irregular longitudinal bends, wind cannot pass through and it has the characteristics of windproof and good warmth retention.
ptfe waterproof and breathable membraneFor clothing applications, polytetrafluoroethylene is used as raw material, which is expanded into a microporous film, and then the film is coated on various surfaces using a special process. on a fabric or paper substrate to make it a new type of material. The polytetrafluoroethylene clothing membrane must not only be moisture-wicking, breathable, and comfortable to wear, but also protect medical staff from infection by various contaminants such as viruses and small bacteria during diagnosis and treatment, resist the intrusion of water, alcohol, and blood, and prevent Dust gets in.
The currently independently developed ptfe waterproof and breathable membrane is the core material for jackets, firefighting suits, ski suits, and protective suits, and has excellent water-repellent properties. It can well block the intrusion of rainwater outdoors, and at the same time has good breathability and can maintain human body comfort.
