The functional waterproof, oil-proof and anti-fouling fabrics are treated with nano-interface super-amphiphobic technology to form a protective film on the fabric interface. Nano three-proof technology refers to the water-repellent principle of lotus leaf, and integrates nano-materials into fabric fibers to form a three-dimensional net protective layer, so as to achieve the effect of waterproof, oil-proof and anti-fouling, and it can also maintain the original performance of the fabric. Soft and delicate, breathable, non-toxic and environmentally friendly, it can also prolong the service life of the fabric, not easy to change color, and more comfortable to wear
