Sun protection clothing is not reliable, cotton clothing has good sun protection effect

In the hot weather, the “furnace” of Nanjing began to take off, and the sales of sunscreen clothing that was touched with a plastic texture and showed translucent shape also gradually “warmed” like the temperature in Nanjing. How big is the sun protection effect of “Sun protection clothing”? The reporter conducted relevant visits yesterday.

Whether it is in a large shopping mall, or the underground passage of Xinjiekou, you can see this kind of sunscreen clothing that has a plastic texture, a slightly transparent, colorful color, from thirty to fifty yuan to a few hundred dollars. Have. On the label of some low-cost sunscreen clothing, the reporter did not find any "protection factor" logo. Although there is a slight "three noes", there are still many people who choose to buy cheap sunscreen clothing. A shopkeeper selling sunscreen clothing vaguely said that the fabric of the sunscreen clothing is actually a regular fabric, but with the addition of "sunscreen dyes", it can achieve the sunscreen effect.

What is sun protection clothing? The reporter learned that sunscreen clothing began to be popular in the United States in 2007, and then entered China. According to the data, the principle of sun protection for "sun protection clothing" is to add anti-ultraviolet substances to the fabric to make the clothing have the function of sun protection. At present, in China, such UV-resistant fabrics are mostly used in outdoor products, and there are still few applications in ordinary garments. In 2011, China introduced the latest evaluation standard “Assessment of UV Protection Performance of Textiles”, which clearly states: only when the UPF (UV Protection Index) value of clothes is greater than 30, and the UVA (the most penetrating UV) is transparent. When the rate is less than 5%, it can be called "UV protection products".

Jiang Yi, director of the dermatology department of the Second Affiliated Hospital of South Medical University, said that if the price of sunscreen clothing is too cheap, the label is also "three no", such sunscreen clothing is basically not reliable. "In fact, the ordinary clothes we wear, such as cotton T-shirts and silk-made clothes, have a good effect on UV protection." Many people think that sunscreen clothing can be used to prevent ultraviolet rays. In fact, normal cotton clothing is usually worn. The sunscreen effect is not bad. Jiang Yi used to use UV light tester to test. The results of UV and silk mulberry silk fabrics are far better than those of chemical fiber and polyester.

Special reminder that the towel is cold and cold, and the skin can eliminate the burning sensation after exposure.

Many people will find that if they suffer from exposure due to force majeure, the skin will appear red and swollen and hot after sunburn. This is an acute skin injury that requires timely treatment. Experts advise that sunscreen should be applied as much as possible in the summer, it is best to wear dark clothes, because ultraviolet light is easier to penetrate light clothes. Once the summer skin is exposed to the sun, it is best to use cold boiled water to scrub the skin. First wipe off the sweat with a dry towel, then apply a cold water towel to the skin for a while, so that you can quickly eliminate the burning sensation of the skin. (Correspondent Cui Yuyan)
