This method for coating fabrics with omniphobic chemicals produces fabrics that retain the coating much longer
The method is solventless and therefore more environmentally friendly
Since the coating is less than 1 micron thick it allows the fabric to retain breathability
This invention is a method of 3D coating of fabrics at submicron thicknesses with PFAS to produce omniphobic (both hydro- and oleo-) fabrics in a more efficient and environmentally friendly manner. Fabrics coated using the inventive method maintain omniphobicity much better than the standard method of spraying. The invention uses a solventless, vapor-deposition technique to deposit the omniphobic material.
This method of 3D coating of fabrics allows production of omniphobic material (both water and oil repellent) in an efficient and environmentally friendly manner. The fabric coatings are more robust, durable and functional than current methods provide.
The fashion industry can use this method to produce water repellent clothing better, faster and cheaper. Industrial clothing manufacturers can produce oil repellent materials with greater safety and durability capabilities.
