Colored anti ultraviolet and anti UV polyester yarn can effectively isolate the projection of ultraviolet ray, and use anti ultraviolet polyester The anti ultraviolet UPF of the fabric woven with nylon silk can reach 50%.
The colored anti ultraviolet and anti UV polyester yarn is used for weaving outdoor sun protective clothing, sunshade and sunshade The conventional specifications are 50D, 75D, 100D, 150D, 250D and 300D Excessive ultraviolet radiation is harmful to human beings and can even cause skin cancer. How to reduce the transmission of ultraviolet rays on fabrics More and more attention has been paid to it by modern people.
The direction of ultraviolet ray on the fabric is generally light transmittance + reflectivity + absorptivity = 100%. Visible light passing through The lower the ratio, the higher the reflectivity and absorptivity, the better the protective performance of the product.
Jinxia's products have strong UV protection performance: 1. Polyester contains benzene ring, which has high UV
Line absorption capacity. 2. In the process of spinning, organic UV absorber and Inorganic UV shielding agent are added to make the product have a good performance It has high ultraviolet absorption and reflectivity, which greatly reduces the transmittance of ultraviolet.
According to the national standard GB / T 18830-2009, as long as the UPF value of the product is greater than 30, and the transmission rate of UVA is higher than 30 When it is less than 5%, it can be called "anti ultraviolet product", and the label is: upf30 +. The reference value of product UPF of Jinxia is 70-80, the transmittance of UVA is less than 5%, and the label is upf70 + or upf80+。
