In the field of textile finishing, the term impregnation is sometimes used synonymously for the hydrophobization of the textiles, which is subdivided into a water-pressure-resistant and a water-repellent equipment (textile), but on the other hand also only for a waterproofing equipment. It also plays a role that, under impregnation, the achieved state is understood by impregnation. Depending on the requirements for washing, cleaning and weathering resistance, paraffin wax emulsions, but also film-forming silicones and fluorocarbons, which form a good permanent protection, are used as impregnating agents. By impregnation, however, agents are also introduced into textile materials which make them wrinkle-free, food-resistant (moth and cage protection), rot-proof, flameproof, but also hydrophilic. Some of the fluorocarbon resins (PFCs) used as impregnants can accumulate in the human organism and impair human reproductive capacity.However, vendors of impregnants do not need to disclose whether they use fluorocarbons. Although it is prescribed by law in Europe, no fluorocarbon resins (PFC) no matter which surface to use!
