Colored anti-uv Polyester Yarn, too much UV radiation is harmful to humans, and can even cause skin cancer. How to reduce the transmission rate of ultraviolet radiation on fabric has attracted more and more attention of modern people. The direction of ultraviolet radiation on the fabric is usually light transmittance + reflectivity + absorptivity = 100% . The lower the transmittance of visible light, the higher the reflectivity and absorptivity, the better the protection performance of the product. Jinxia products have a strong UV protection performance: 1. Polyester containing benzene ring, itself has a high UV absorption capacity. 2. In the spinning process, the organic ultraviolet absorber and the inorganic ultraviolet shielding agent are added, so that the product has a high ultraviolet absorption and reflectivity, which greatly reduces the ultraviolet transmittance. According to the National Standard Gb/t 18830-2009, only when the UPF value of the product is more than 30, and the transmittance of UVA is less than 5% , can it be called "anti-ultraviolet product" , the label is: UPF30 + . Jinxia products UPF reference value of 70-80, UVA transmittance of less than 5% , identified as: UPF70 + or UPF80 + .
