The right amount of ultraviolet light has certain benefits to the human body and living things, but excessive ultraviolet radiation can damage the living organism and reduce the life of interior decorations and furniture. Most curtains have certain UV protection functions, especially thick and high-density fabrics can block most of the UV rays, and some fibers such as hemp and bamboo fiber also have good UV protection. For thin curtains that require better light transmission, and hope to shield ultraviolet rays, inorganic or organic anti-UV agents can be added to the fabric, among which inorganic oxides are used more, such as zinc oxide, titanium dioxide, silicon oxide, and aluminum oxide. , magnesium oxide, etc. Such mineral micropowders, especially when they reach the nanometer scale, have a particle size similar to that of ultraviolet rays, a large specific surface area, and a high surface energy, which can reflect and scatter some ultraviolet rays. At the same time, after some electrons are activated, a series of chemical reactions occur that convert energy into heat and light, and still have normal light into the room.
