Is the sunscreen full of "black technology" reliable?

According to the standard determination of GB/T 18830-2009 "Evaluation of Textiles Anti-UV performance", when the upf of the sample is UPF> 40, and T (UVA) AV <5%, it can be called "UV products". UVA refers to the sunlight ultraviolet radiation with a wavelength of 315nm-400nm. UPF is the ultraviolet protective coefficient. The larger the UPF value, the lower the transmission level.

In a variety of promotional "cooling" and "ice" sunscreen, the reporter noticed that the fabrics mostly displayed as nylon and amino, and a small number of polyester fibers contained.

Public information shows that nylon has strong abrasion resistance, high density, and good anti -wrinkle; high elasticity of spandex, good acid and alkali, sweat resistance, seawater resistance, dry washing resistance, and good abrasion resistance; polyester fiber; polyester fiber Wrinkles and preservation are good, and have high strength and elastic recovery ability.

The reporter learned in the industry that nylon, aminoly, etc. are currently widely used in the field of clothing. If sunscreen contains technology, other functional materials are not ruled out.

Some people in the textile industry told the media that the sunscreens that claim to have "black technology" now have added anti -ultraviolet agents and other ingredients to the fabrics.

As a result, the high UPF value, low UVA passing rate, and cool breathability effect.

Another textile chemical engineer pointed out that the sunscreen clothing is mainly based on the two indicators, what fabrics to adopt, and what kind of ultraviolet barrier used in the fabrics. Many of the so -called "black technology" are many of the merchants in order to increase the comfort of the sunlight clothing to wear the comfort. Some are even marketing gimmicks, which has nothing to do with clothing sunscreen.

From the perspective of the comprehensive industry, although some clothing companies are committed to scientific and technological investment, some brands may not be so strict in sunscreen standards or have a "deficiency" phenomenon.

Zhongxin Finance noticed that there have been problems with "sunscreen" in many places.

For example, before, the results of the third and fourth quarter of 2021 in the market supervision and administration bureau of Guangxi Zhuang Autonomous Region were released in the third and fourth quarter of 2021. Playboy sunscreen was previously spotted by the Shaanxi Provincial Market Supervision Bureau.

In August 2021, the Beijing Consumer Association compared 40 sunscreen samples to compare the experiment that the tag did not marked the sunscreen function. The webpage publicity claimed that there were 14 samples with this function. 26 pieces. There are 5 standards or nominal requirements, involving AUM, Adidas, Keep, Mu and other brands.

The Beijing Consumer Association also reminded: When purchasing sunscreen products, pay attention to whether there are clear sunscreen parameters and related standards on the product tag. Essence

How to choose sunscreen correctly?

According to the summary of the China Consumers Association, in the face of a wide range of sunscreen products, don't just blindly listen to advertising, master the following small tricks, and quickly choose a high -quality sunscreen.

The first is to see the material. Priority to choose polyester sunscreen, followed by silk, and then cotton sticky, nylon, acrylic -based sunscreen. High -quality sunscreen clothing fabrics should be light and breathable. If the sunscreen jacket with good sunscreen effect is poor, wearing it on the body will have a serious sense of stuffy, bringing discomfort.

The second is to see the color. The dark color is better than light -colored anti -ultraviolet rays. The effect of dark red and Tibetan blue sunscreen is better than other colors.

The third is to look at the label. Regular anti -ultraviolet products should be marked with national standard numbers and UPF values. The UPF value is generally 40+ or ​​50+. The larger the UPF value, the better the ultraviolet effect.

The fourth is to look at the lines and light transmission. The thinner and dense the sunflow textile texture, the less light, the better the sunscreen effect.

In addition, try to choose sunscreens that can be protected in large areas. Summer sunscreen should protect the body in all directions. When consumers buy sunscreen, they must pay attention to the models of sunscreen. They can choose sunscreen jackets with long sleeves, sunscreen caps, and even hand -designed design.

Try to choose sunscreen with good breathability and cool body feel. When choosing, consumers can put fabrics on their mouths and blow them through their hands. With their hands on the other side, they feel through the wind through the wind. If they are not very effective, they can feel that the wind is through, indicating that the product's breathability is good. (Zhongxin Financial Reporter Xie Yiguan)
