How to choose sun-protective clothing and how to test whether sun-protective clothing is useful

In summer, people not only apply sunscreen, but also use parasols and wear sun-protective clothing. Sun-protective clothing has a sun-protective effect. When choosing sun-protective clothing, you should pay attention to the fact that the sun protection factors of various fibers are different.

When choosing sun-protective clothing, the first thing to look at is the sunscreen ingredients, followed by the price, and then the label.

1. Look at the sunscreen ingredients

Whether sun-proof clothing can block the sun depends on its ingredients. Just like cosmetics, the light transmittance and density of sun-proof clothing are related to the degree of sun protection. A boss who sells sun-proof clothing admits that sun-proof clothing is long-sleeved, but thinner and cooler than ordinary clothes, and he does not know the sun protection effect. Professionals say that the sun protection effect depends on two aspects, one is the density of the sun-proof clothing material, and the other is its own light transmittance.

Common fabrics: The first type is colored cotton fabric clothes. Bright colors such as cyan, red, blue, and green have the highest isolation rate against ultraviolet rays; the second type is sun-proof fabric. The production principle of this type is very simple. In fact, it is to add sun-proof additives to the fabric; the third type is special fabric clothes, such as silver reflective material.

2. Look at the price

This summer, a lady bought a sun protection jacket early on. She bought it online for 29.9 yuan, but she didn't feel that it had any sun protection effect. It was about the same as ordinary long-sleeved clothes. Moreover, the sun protection jacket looks good, but it is not comfortable to wear. It has poor breathability and you will sweat after wearing it for half a day. From a professional point of view, sun protection is mainly divided into light protection, UV protection (abbreviation of Ultraviolet, i.e. ultraviolet rays) and heat absorption. The effect of sun protection is related to the density of the fabric. The higher the density, the better the sun protection effect. Therefore, sun protection jackets that are too cheap have no sun protection effect and are just a gimmick.

3. Look at the label

Clothing made of regular sun-proof fabrics will have a clear UV protection factor on its clothing label. Relevant people remind consumers that when purchasing UV-proof textile and clothing products, they should first check the product manual to see if there is any introduction to the product's UV protection function. The main reference indicator for sunscreen items is the UPF index. You should try to choose textile and clothing products with UPF (ultraviolet protection factor)>30 and T (UVA) (i.e. the ratio of transmitted flux to incident flux when the wavelength of sunlight ultraviolet rays is 315cm~400cm) <5%.

Look at the UPF value of the sun-proof clothing. The higher the UPF value, the better the sun protection effect. Generally, there is relevant information on the label of the sun-proof clothing, whether it is marked with words such as anti-ultraviolet textiles. However, we all know that even if a particularly cheap sun-proof clothing has such a mark, it is very likely to be fake. It is best to choose a dark color. Like black is good. It may feel a little hotter than light colors, but the sun protection effect is better. The fabric should be thicker and the fabric density should be higher. In other words, the finer the texture of the fabric, the better the sun protection effect. However, there are certain disadvantages, and the breathability may be a little worse. So when choosing, you can't just pursue the sun protection effect. Summer is too stuffy, and the human body is also uncomfortable. Use ultraviolet rays for testing. It is just a common lamp for testing counterfeit banknotes. Shine the light on the clothes. The less light penetrates, the stronger the anti-ultraviolet function. You might as well bring it when you go to the mall to buy sun-proof clothing. Blow with your mouth to test the breathability of the fabric. Blow the fabric with your mouth. If it can penetrate the clothes, it means that the breathability is good. On the contrary, the clothes may be less comfortable to wear.

The principle of sun protection clothing is to add sunscreen additives to the fabric to make anti-ultraviolet fabrics. Some sunscreen fabrics use ceramic micropowders combined with fibers to increase the reflection and scattering of ultraviolet rays on the surface of the clothes, preventing ultraviolet rays from passing through the fabric to damage the human body. Most of the "sunscreen clothing" sold by merchants actually has a very poor effect on ultraviolet isolation, especially those products that claim to be light and thin. Most of them are clothes that are sun-proof and non-fading, not skin-proof. Sun protection clothing is generally divided into colored cotton fabric clothes. Bright colors such as cyan, red, blue, and green have the highest isolation rate for ultraviolet rays. The second type is sunscreen fabric. In fact, the production principle of this type is very simple. In fact, it is to add sunscreen additives to the fabric. If there is a special need, the fabric will be thickened and finished. The so-called thick finishing is to make the fabric weave denser.

no the same.

There are differences in air permeability and sun protection principle between windbreaker and sun protection clothing. Windbreaker can prevent wind and water, but has poor air permeability and poor sun protection ability. Sun protection clothing is mainly sun protection, and special sun protection additives are added to the fabric, which has better air permeability. Windbreaker and sun protection clothing are different, with different functions, different air permeability, and different working principles. Windbreaker: As the name suggests, it is a windproof and thin coat. Its main function is windproof and waterproof, so it requires good air tightness, so it has poor air permeability. The function of windbreaker is waterproof, windproof and warm, and it does not require high sun protection. Therefore, sun protection fabrics are rarely used in the selection of materials, and special sun protection treatment is rarely performed in processing. Sun protection clothing: Good sun protection fabrics have good air permeability, can quickly lead sweat to the surface of the fabric, and dry quickly. Inferior fabrics absorb moisture and have poor air permeability, which can easily make people feel uncomfortable when worn for a long time. Sun protection clothing is made of high-quality polyester fiber, and anti-ultraviolet fabric with sunscreen additives added to the fabric. A layer of sunscreen coating is applied to the inner layer of the clothing, just like a parasol. A sun protection clothing can isolate 95% of ultraviolet light and play a sun protection effect.
