Is wearing sun protection clothing useful?

Although sun-protective clothing is clear, it contains substances that block ultraviolet rays, which increases the refraction and scattering of ultraviolet rays on the surface of the clothing and reduces the damage of ultraviolet rays to the skin. However, wearing sun-protective clothing cannot guarantee that you will not get tanned at all. It may just reduce the exposure to ultraviolet rays and make it less likely to get very dark. If you want to avoid getting tanned completely, you need to add other sun protection measures.

It contains no or only a little sunscreen. When purchasing sun-protective clothing, you should pay attention to the UPF value on the trademark that is greater than 30 and the UVA transmittance is less than 5%. Only then will it be a sun-protective product with a very good sun protection effect. Sun-protective clothing with darker colors may have better sun protection effects. If you are worried about dark colors absorbing heat, you can choose red sun-protective clothing, which also has a good sun protection effect.

Sunscreen is indispensable for sun protection. The higher the SPF value on the sunscreen, the longer the sun protection time and the better the sun protection effect. PA refers to the index of resisting UVA suntan, with " " indicating the intensity, so the more this symbol, the stronger the sun protection. In addition to sunscreen, it is best to bring a parasol when going out. Choose a polyester umbrella with a tight fabric and a coated surface for better sun protection.

Sun protection clothing selection

Try to choose darker sun-protective clothing. Experiments show that black clothing has a better sun-protection effect than light-colored clothing, and light-colored clothing has a poor sun-protection effect. Therefore, black, purple, and red are the best colors to choose when buying sun-protective clothing. In addition, the sun-protection function of sun-protective clothing is closely related to the material of the clothing. Generally speaking, polyester has the best sun-protection effect, followed by nylon, silk, and rayon.

Try to choose sun-protective clothing with a high protection factor. Consumers should check the packaging label when purchasing, and pay attention to the UV protection performance indicators [protection factor (UPF value) and transmittance (UVA value)] on the label. my country's "Evaluation of UV Protection Performance of Textiles" stipulates that only when the UPF value of a product is greater than 30 and the UVA transmittance is less than 5%, it can be called an "UV protection product." The higher the UPF value, the better the sun protection effect.

Try to choose sun-protective clothing with good breathability. When buying sun-protective clothing, you should not ignore its breathability.

Try to buy sun-protective clothing that can protect a large area. Summer sun protection should protect the body in all directions.

What should I pay attention to when wearing sun protection clothing?

Sun protection clothing also needs to be well maintained. It is best not to wear it for a long time. Pulling or washing it, and placing it in a humid place will reduce the protective function! Please wash it by hand, do not soak it for a long time or rub it vigorously, and treat our baby gently!

1. Store sun protection clothing in a dry and ventilated place.

2. Avoid wringing out the sun-protective clothing by hand.

3. Avoid exposing sun-protective clothing to the sun.

4. Try to avoid washing sun-protective clothing frequently.

5. Try to wash the sun-protective clothing by hand and avoid using a washing machine frequently to avoid damaging the sun-protective properties of the sun-protective clothing.

Can sun protection clothing protect against UV rays?

Most sun protection clothing cannot block ultraviolet rays. The anti-ultraviolet performance of clothing refers to the ability to reduce the amount of ultraviolet rays transmitted through the fabric to prevent various skin damage caused by excessive exposure to ultraviolet rays, while also being able to scatter and reflect light. Anti-ultraviolet performance is usually expressed by UPF, or ultraviolet protection factor. The higher the UPF value, the better the anti-ultraviolet performance.

The test results show that among the 26 samples claiming to have sun protection function, 14 samples have UPF values ​​greater than or equal to 50, and the sun protection effect is relatively good. However, 9 samples have UPF values ​​less than 20. Among them, the UPF value of the men's ultra-thin jacket with the nominal "Beaume" brand is 5, and the UPF value of the women's sun protection jacket with the nominal "Maioule" brand is 8, which basically has no UV protection effect.

Among the 26 samples claiming to have sun protection function, 15 of them clearly stated the UPF value, ranging from greater than 20 to greater than 50. According to the results of the comparative test, the nominal value of the UPF of two of the sample garments was quite different from the measured value. This comparative test selected 4 clothing samples with similar fabrics and styles, but did not claim to have sun protection function. Their UPF values ​​were tested and the results were 3, 6, 22 and 31 respectively. Note: my country's GB/T18830-2009 standard stipulates that when UPF>40 and (UVA)AV<5% (marked as UPF40), it can be called an "anti-ultraviolet product."

Common fabrics for sun protection clothing

Cotton sun protection clothing

Sun protection clothing made of cotton fabric generally has very bright and eye-catching colors. These bright colors can effectively isolate ultraviolet rays and reduce the absorption of the skin. Common colors include cyan, red, blue, green, etc.

Polyester fiber material

Sun protection clothing made of polyester fiber is better, especially anti-ultraviolet fabrics with sunscreen additives added to polyester fiber fabrics, which can increase the scattering and direct radiation effect of sun protection clothing on ultraviolet rays and sunlight, and prevent ultraviolet rays from passing through the sun protection clothing to damage human skin.

Sun protection clothing made of chemical fiber materials

The thin, translucent sun-protective clothing we often see is mostly made of microporous fibers that have been treated with UV protection. Not only can it provide sun protection, but the microporous structure also increases the moisture absorption and perspiration of the fabric, making it more suitable for wearing in hot environments. This type of sun-protective clothing is mostly made of chemical fiber products, such as polyester, acrylic, nylon, etc.
