Dye-based UV protection fabrics are specially treated textiles that incorporate UV-absorbing dyes or pigments to enhance their ability to block harmful ultraviolet (UV) rays. These dyes are either embedded into the fibers during manufacturing or applied as a surface treatment, allowing the fabric to achieve a higher Ultraviolet Protection Factor (UPF) rating.
The UV-blocking dyes work by absorbing or reflecting UV radiation, reducing skin exposure to both UVA and UVB rays. This method of protection is often used in synthetic fabrics like polyester and nylon, but can also be applied to natural fibers such as cotton or viscose to improve their sun resistance.
