From a professional point of view, people often say that “parasols and sun umbrellas†are actually umbrellas against UV rays. He Lingjun, Secretary General of the Umbrella Special Committee of the China Sundries Industry Association, told the Life Times reporter that choosing this kind of umbrella should be noted. The following three aspects. First, look at the tags. Mainly look at the protection index, UPF and UVA values, only UPF is greater than 40, and UVA transmittance is less than 5%, can be called UV protection products, UPF value is greater, its better UV protection performance. In general, most of the signs on the market are "UPF50+", and its protective function is sufficient. Second, look at the colors. Under the same conditions of the fabric, dark umbrellas have better UV protection. The biggest difference between parasols and other umbrellas is their UV protection coating, which prevents UV penetration. Third, look at the fabric. The thicker umbrella surface and the tighter cloth fabric have better UV resistance. Compared to cotton, silk, nylon and other fabrics, polyester is more sunscreen. To know the sun protection effect of the parasols, try the sun. The darker the shadow, the lower the light transmittance umbrella has the best sun protection effect. When buying parasols, be sure to choose a branded product. Generally regular manufacturers will use brand logos in multiple places, such as umbrella seams. In addition, rain will erode the UV protection coating. It is best to separate the umbrellas and umbrellas. If the surface of the umbrella is dirty, rinse it with clean water or gently knead it by hand, otherwise it will affect the effect.
