The waterproof principle of Teflon treatment is that the textiles prepared by Teflon finishing agent have lower surface energy, and the low surface energy fabric has the above-mentioned "three defenses" due to the non-stick characteristics of the low surface energy of the material. Characteristics and performance. Teflon utilizes the fluorinated active agent in the material (the production process of organic fluorotextile finishing agent requires the use of ammonium perfluorooctanoate, which is currently being questioned by safety, which is a surfactant, given the use of outdoor equipment. Environment, we all need not have any panic. The ingredients to reduce the surface energy of the textile, so that the fabric achieves a certain waterproof function.
