Why DuPont three-proof Teflon additive can have three-proof effect
DuPont three anti -aid agent is a chemical preparation developed by DuPont and a fluorocarbon resin. Due to the good stability of fluorocarbons, strong resistance to high and low temperatures, and the extremely low surface energy of fluorocarbons in the air, the surface of the fabric after being treated with fluorine-containing DuPont Teflon three-proof additives The tension is greatly reduced and lower than water molecules and oil molecules, so it has excellent water- and oil-repellent properties. When water-soluble or oily stains are spilled on the fabric, they will not penetrate into the fabric but will also form water beads, like The water drops on the lotus leaves are rolling around. Therefore, DuPont Teflon is currently mainly used in the fabric industry for the so-called “three-proof” finishing of fabrics, that is, water-proof, oil-proof, and stain-removing finishing.
The water-repellent principle of DuPont Teflon three-proof additive treatment is that the fabric treated with DuPont Teflon three-proof additive has a lower surface energy. The low surface energy of the material has non-stick characteristics. Therefore, low surface energy fabrics have the characteristics and performance of three-proof. DuPont Teflon three-proof additive uses the fluorine-containing active agent component in the material to reduce the surface energy of the fabric, so that the fabric can achieve a certain three-proof function.
The production process of DuPont Teflon three-proof additive requires the use of ammonium perfluorooctanoate, which is currently being questioned about its safety and has yet to be concluded. This is a surfactant. The environment in which outdoor equipment is used does not cause obvious damage to the human body itself.
