How to choose sun protection clothing when you really need sun protection in spring?

Spring is warm and the flowers are blooming, and it’s time to go out for an outing again. But don’t forget that although the temperature is not high in spring, ultraviolet radiation is gradually increasing, so sun protection is also necessary in spring! When it comes to how to protect yourself from the sun, sun protection clothing has now become the choice of many people. But faced with countless styles of sun protection clothing on shopping platforms, a vexing question arises: How to choose sun protection clothing? Is more expensive really better?

1. Please pay attention to the national standard when choosing sun protection clothing. 2. Cheap sun protection clothing with national standards is also good. 3. Choose light-colored sun protection clothing for summer, which is more comfortable. 4. It is best to replace sun protection clothing every 3 years. 5. It is best not to use sun protective clothing as a raincoat.

How does sun protection clothing protect you from the sun?

Before choosing a piece of sun protection clothing that suits you, let’s first understand the sun protection principles of sun protection clothing.

Clothing fabrics worn daily actually have certain UV protection functions. Because when ultraviolet rays irradiate the surface of clothing, reflection, scattering, and absorption will occur. In this way, the amount of ultraviolet rays that penetrate the fabric and reach the surface of human skin will be reduced, and the skin will be less damaged by ultraviolet rays.

The same principle applies to sun protection clothing, but it is more professional than ordinary clothing.

At present, sun protection clothing fabrics generally follow two principles to achieve UV protection:

1. Shielding principle: Enhance the reflection and scattering of ultraviolet rays by fabrics, such as applying a shielding agent coating to the inner layer of the fabric, or adding a shielding agent to the fibers of the fabric;

2. Absorption principle: Enhance the absorption of ultraviolet rays by fabrics, and convert the energy after ultraviolet absorption into heat energy release or harmless low-energy radiation. For example, when dyeing fabrics, choose dyes with better ultraviolet absorption, or make fabrics anti-ultraviolet absorption. Agent coating finishing.

When choosing sun protection clothing, just look at this label

In our country, the most basic requirement for sunscreen textile products is that they must meet the provisions of the national standard GB/T 18830-2009 “Evaluation of UV Protection Performance of Textiles”, that is, “UV protection textiles must reach UPF > 40 and UVA transmittance < 5% , can it be called an anti-UV product."

Why choose these two indicators?

Among them, the ultraviolet protection factor (UPF) refers to the ratio of the average effect of ultraviolet radiation calculated when the skin is unprotected to the average effect of ultraviolet radiation calculated when the skin is protected by fabric. The larger the UPF value, the better the UV protection performance of the textile. good.

However, consumers do not have to blindly pursue high UPF values. A UPF value of 50 can achieve high UV protection performance. No matter how high the UPF value is, it has little significance in improving the UV protection performance of textiles.

UVA is the longest wavelength part of ultraviolet rays and has strong penetrating power. It can directly reach the dermis layer of the skin and destroy elastic fibers and collagen fibers. The smaller the UVA transmittance, the better the UV protection performance of textiles.

The most direct basis for consumers to purchase sun protection clothing is that the product must have a clear label that meets the national standard GB/T 18830-2009 “Evaluation of UV Protection Performance of Textiles”. The identification content must include the following parts:

Standard number, namely GB/T 18830-2009

When 40<UPF≤50, it is marked as UPF40+. When UPF>50, it is marked as UPF50+;

The protection provided by this product may be reduced with long-term use and when it is stretched or wet.

Is sun protection clothing more expensive, the better?

  Choose dark or light color?

At present, the price of sun protection clothing sold in the market ranges from tens of yuan to hundreds of yuan. In fact, considering the overall cost of fabric, design and process, sun protection clothing with more than 100 yuan and the above logo can be purchased with confidence. It is not recommended to buy sun protection clothing that is too cheap.

Some sun protection clothing sell at a high price, and a large part of it includes factors such as brand premium and design style. As long as it meets the national standards, its UV protection function for the skin is not much different.

In addition, many friends will struggle with the color issue.

Thick dark-colored clothing will have better UV protection because most of the UV rays will be absorbed by the clothing fabric, and the UV rays that penetrate the fabric to reach the skin surface are greatly reduced. However, in the hot summer, the innate physical sun protection advantage of thick dark clothing becomes a disadvantage. Such fabrics absorb a large amount of ultraviolet rays, which will cause the temperature of the clothing itself to rise, making people feel stuffy.

Professional sun protection clothing can provide sufficient and effective UV protection. At this time, the color and thickness of the clothing are not the most critical UV protection factors. In this case, you can choose light-colored and light sun protection clothing to achieve sun protection and comfort. Effect.

How often does it take to replace your sun protection clothing?

The UV protection performance of sun protection clothing will gradually decrease with use. Point 3 of the national standard mark that the aforementioned sun protection clothing must be equipped with also clearly states this (that is, “long-term use and under stretched or wet conditions”). the protection provided by this product may be reduced”).

The main factors that affect the performance of sun protection clothing include: length of use, ambient temperature, sweating, number of washes, and daily wear and tear.

For example, long-term exposure to the sun, repeated folding and stretching when wearing clothes, and soaking with sweat and heat, etc., will gradually damage the fabric and anti-UV coating, and weaken the anti-UV performance. The washing process will cause the anti-UV coating on the surface of the fabric to peel off, resulting in a reduction in the anti-UV performance of the fabric. In addition, the fabrics of sun protection clothing are generally thin. When worn, the fabric structure will become loose due to wear on the surface, which will increase the transmittance of ultraviolet rays.

As an ordinary consumer, it is difficult to test the UV protection performance of the fabric before use, but you can still make a rough judgment through naked eye observation. When the fabric of the sun protection clothing appears faded, loose, light-transmissive, and deformed, Consumers should consider changing to new sun protective clothing.

There are also scientific studies that show that sun protection clothing that has been used for 3 years will lose 100% of its UV protection performance (that is, it will not meet the requirements of the aforementioned national standards). This length of use can also be used as a reference for updating sun protection clothing.

Nowadays, there are many sun protection clothes that claim to be waterproof and splash-proof. It is not harmful for consumers to use sun protection clothes as temporary raincoats in light rainy weather. Generally, the sun protection performance of the clothes will not be significantly damaged, but it is still not recommended to use sun protection clothes as temporary raincoats. When used as a raincoat, the main reason is that the waterproof and anti-splash functions of sun protection clothing cannot achieve the function of continuous rain protection; at the same time, it is recommended that clothing with specific protective functions be “exclusively used”, so that the maximum effectiveness of the clothing design function can be exerted .

In addition to sun protection clothing, many people choose to use parasols, wear ice sleeves and other measures to protect themselves from the sun.

Parasols can block direct sunlight well, but they cannot block sunlight reflected or scattered by the ground or other objects; ice sleeves are mainly used for sun protection on the arms and are also partial sun protection. Sun-protective clothing such as sun-protective clothing, parasols and ice sleeves are all effective sun protection tools. It is recommended that consumers choose the most suitable sun protection measures based on specific scenarios.
