Is it useful to prevent UV service? What color is good?
The fabric taken by sunscreen is also an ordinary fabric. However, when dyeing the factory dyeing processing, it is necessary to use a assistant to improve the sun accuracy of the fabric, that is, the color fastness to prevent degeneration.
1. Meaning
The main role of sunscreen is to prevent the direct exposure of the sun's ultraviolet rays. The effect is the same as the Parasol, which makes the Skin from being darkened with the sun. This is a compulsory course for many beautiful ladies.Of course, Sun protection is not just for beautiful women.All outdoor activities should take care of themselves to pay attention to sunscreen.
The biggest feature of Outdoor sunscreen clothes is translucent, which is cool and sunscreen.Its principle is to add sunscreen auxiliary ultraviolet fabrics to the fabric. There are also some sunscreen fabrics that use ceramic micro powder and fiber to increase the reflection and scattering effects of clothes to prevent ultraviolet rays from damaging human Skin through fabrics.
2. Classification
Usually the "sunscreen clothing" sold by merchants is actually very effective for ultraviolet isolation, especially those products that are called lightness, most of them are clothes sunscreen and not anti -Skin.
Sun protection clothing is generally three types: one is colorful cotton fabric clothes. Blue, red, blue, and green are the largest isolation rates of ultraviolet rays.The second is sunscreen fabric. This kind of production principle is very simple. In fact, the sunscreen auxiliary agent is added to the fabric.Some.The third is special fabric clothes.
Three, principles
Sun protection clothing began to popularize in the United States in 2007, and then entered China.In China, most of the UV fabrics are mostly used in outdoor products, and there are relatively few applications in ordinary clothing.
On January 1, 2011, my country launched the latest assessment standard "Evaluation of Textiles Anti -UV performance".This stipulates that only when the UPF of the product is greater than 30 and the UVA transition rate is less than 5%, it can be called "anti -ultraviolet product"; ultraviolet products should be marked with the following three aspects on the label: 1. This.Standard numbers, that is, GB/T18830; 2.UPF value: 30 or 50; 3. Long -term use and in the case of stretching or humidity, the protection performance provided by the product may be reduced.In this evaluation criteria: UVA refers to the part of the part that harms the human body in ultraviolet rays, and UPF refers to the degree of transmission of ultraviolet rays. The larger the value, the lower the transmission level.
Fourth, parameters
It is not difficult to find that many sportswear brands have anti -ultraviolet clothing products when visiting the shopping mall clothing counter. The signs of these clothing clearly indicate related parameters such as clothing materials and UPF indexes.There are so -called sunscreen clothing in a small number of fashion brands, but most of them have not found related signs.
In the past two years, some merchants have applied the concept of Sun protection to ordinary clothing. Because the public knows very little about sunscreen fabrics, there are inevitably some situations that are false by falseness.Therefore, people should not be blindly attracted by various fancy propaganda when buying sunscreen clothing.The clothing made of regular sunscreen fabrics will marked clear sunscreen parameters on their clothes signs. If not, it is recommended that you do not buy it.In addition, long -term washing or stretching can cause the sunscreen performance of clothes. At this time, you need to replace or re -add a additive to the clothing. The specific practice refers to the relevant instructions of the product.
Five, color
Everyone will wear light -colored clothes in summer. In fact, in summer, wearing red -colored clothes is the most Sun protection!And red is so good for health, so everyone should wear red color!But there is another point. If you are wearing a red cotton T -shirt to climb and play, it is not a good choice, because the cotton clothes are not easy to dry, and the wet fabrics affect sunscreen very much.Add a bit of chemical fiber fabric will be better in this point.
Wearing red presence is good for health.Each of the ozone in the atmosphere is reduced by 1%, and the ultraviolet rays that are irradiated to the ground increase by 2%, while the incidence of Skin cancer increases by about 4%.Wearing red clothes and skirts in the sun can reduce the damage to the Skin by ultraviolet rays. This is because ultraviolet rays are the shortest wavelengths of the wavelength of the red light in the sun.Living, so wearing red clothes can absorb and filter more sun ultraviolet rays, which can reduce the damage to the Skin by ultraviolet rays.In summer, we wore some professional sunscreen in the outdoor activities.Among them, professional production of sunscreen clothing has the longest wavelength, which can absorb a large amount of ultraviolet rays in the sun, which can effectively prevent sunburn, while other non -sunscreen clothes cannot prevent ultraviolet rays from preventing ultraviolet rays.
Six, importance
When it comes to sunscreen, many people think that the patent of Ms. Beauty always loves beauty. In fact, Sun protection is very important for everyone.A latest study pointed out that people who have been exposed to long -term exposure in the sun when they are young are prone to eye diseases that may lead to blindness when they are old.However, wearing Sunglasses or hats can reduce the degree of damage.Many people spend their remaining time except for indooring.The inevitable Outdoor is the exposure of ultraviolet rays.Remind everyone to do sunscreen.Sun protection clothing is a necessary weapon for sunscreen.
In summer, many people who are outdoors are biased towards the light color series such as white in their daily clothing. The texture is mostly cotton, which is breathable and cool.However, some experts believe that red clothes are the most sunscreen, and readers can be used as a reference.
Seven, select
1. How to choose sunscreen
Although they are all called sunscreen, most brands of sunscreen clothes are just spoken by salespersons. Only some Outdoor brands are marked with "sunscreen", "UPF40", "UPF30" and other words.There are descriptions such as "UV blocking, which can effectively absorb UVA and UVB".Different from the different sunscreens sold in the market, the fabrics of Outdoor brand sunscreens are almost 100%nylon, with transparent styles and soft texture.
2. UV prevention and sunscreen index are important
It is understood that sunscreen clothes are special clothes for Outdoor travel.The reporter visited several outdoor products stores in several shopping malls. The sales staff in the store showed the reporter a top and trousers, which were sold at about 600 yuan.sales staff said that these two clothes are specifically used for sunscreen. When you go out for walking and long -term outdoor activities (fishing), you can wear this sunscreen.
The top of this dress and the fabric of the pants feels thin and soft.It is reported that the main performance of this clothes is the breathability of the material, and the material of the top is 100%polyester fiber, and the material of the pants is 100%nylon.The label is specially identified by UV prevention and has a Sun protection index logo.
3. recognize the standard label, do not "confuse audiovisual"
Are these sunscreens really or commercial hype?The quality inspection department stated that ultraviolet products should be marked with the following three aspects on the label: the number of this standard, that is, GB/T18830; UPF value: 30 or 50; UVA pass rate: less than 5%; long -term use andIn the case of stretching or humidity, the product provided by the product.
4. According to industry insiders
In terms of color, the darker the color, the higher the protection performance of its ultraviolet rays.In terms of texture, in chemical fibers, polyester sunscreen effects are the best, followed by nylon. The Sun protection effect of artificial cotton and silk is worse than that, while the effect of linen in natural fibers is the best.
However, for people who need long -term outdoor activities or have special requirements for sunscreen due to Skin problems, ordinary clothes cannot meet the needs of their sunscreen, and they need to wear special sunscreen clothes.Therefore, when buying, you must see the Sun protection coefficient marking of clothes. The higher the price, the better the Sun protection effect.
5. Black T -shirts are the most Sun protection but the hottest
In summer, people wearing clothes generally like to choose lighter colors. Black can be described as people's "taboos".However, when it comes to sunscreen, black T -shirts are slightly better than white T -shirts.
During the experiment, the staff also found a black all -cotton T -shirt with the thickness of the white T -shirt.It was found that the long -wave ultraviolet of the black T -shirt was only 4%.
According to optical experts, the darker the color of the clothes, the stronger the absorption of light.Light to white clothes, part of them are reflected and part of them will transmit it. Therefore, wearing white clothes will feel cool, but ultraviolet rays may transmit it on the Skin.When wearing black clothes, the light is basically absorbed. Although the effect of blocking ultraviolet rays is better, the price will feel hotter.This can only be said that everything is beneficial and disadvantaged.
