Application of nano TiO2 in fiber UV protection
Ultraviolet rays that are harmful to the human body are mainly in the 300-400 nm band. Studies have shown that nano-TiO 2 has the property of absorbing ultraviolet rays in this band. If a small amount of nano-TiO 2 is added to the active fiber, ultraviolet absorption occurs, thereby effectively protecting the human body from ultraviolet rays. Chemical fiber clothes and carpets, due to electrostatic friction will produce a discharge effect, and easy to adsorb dust, if a small amount of nano-TiO 2 is added to the chemical fiber, such as 0.1% ~ 0.5% into the fiber or resin, it will Produces good electrostatic shielding performance and greatly reduces electrostatic effects. Adding nano-TiO 2 to synthetic fibers, spinning and spinning can be used to make underwear and garments for sterilization, mildew proof, deodorization, antistatic and anti-ultraviolet radiation. It can be used in the manufacture of antibacterial underwear products and as a strong area for ultraviolet radiation. Dress code. Moreover, since the nano TiO 2 can absorb a large amount of ultraviolet rays, the anti-aging property of the synthetic fiber can be enhanced, and the original is not resistant to the sun and the molecular chain is degraded, thereby preventing degradation of the molecular chain and being resistant to the sun. Clothing and articles made from such fibers can also prevent skin diseases.
