There Is A Serious Lack Of Rules And Regulations In Sunscreen Clothing Industry.

Currently on the market

It is roughly divided into two kinds of waterproof and non waterproof, and the price is up and down more than 25 yuan.

And in some professional outdoor sports.

Counters, known as "skin windbreaker" thin coat, most of the price has risen to 1000 yuan high.

So, does the wide variety of sunscreen clothes on the market really resist ultraviolet invasion?

The Metrology quality inspection and Research Institute consulted experts.

The difference between sunscreen clothing and ordinary clothing products is mainly the function of UV protection.

Functional treatment or fabric design to increase the reflection and scattering of ultraviolet radiation on the surface of the garment, and prevent ultraviolet from damaging the skin through the fabric.

Zhang Haixuan, senior engineer of Shenzhen Metrology quality testing and Research Institute, has been committed to the study of functional fabrics for many years. She said that the national standard stipulates that the UV protection performance of fabrics can reach UPF>40, and pmittance (UV-A) Av<5% can be called "anti ultraviolet products".

The ability to increase and reflect ultraviolet absorption of chemical fiber materials is mainly achieved through 3 ways: increasing the density of textiles, adding some special substances in the textile process, and adding special coatings after the textile is finished.

As for how to choose sunscreen clothes, Zhang Haixuan said that as far as possible to the regular shopping malls, choose a sun protection clothing marked with UPF>40 and sunscreen.

However, she said frankly, to distinguish whether textiles can prevent ultraviolet from being visually failed, we must rely on instruments. Unfortunately, the detection and definition of quality, function, safety and comfort of sunscreen clothing is lack of uniform national standards, and industry regulations and systems are seriously absent.

In addition, Zhang Haixuan reminded consumers that most people think that wearing light colored clothes in summer is more sunscreen and cooler than wearing dark clothes. Actually, this is a mistake.

Wearing light coloured clothes is cool, because the reflective ability of light colored clothes is stronger, but the reflection is mainly infrared. Ultraviolet light has a stronger penetrating power to light colored clothes, and brings greater harm to the human body.

Purple and black absorb ultraviolet light better than other colors.

In addition, plucent and hollowed clothes basically can not protect against sunscreen.

Therefore, summer can choose dark, loose long sleeved clothes, which will be more sunscreen and cool.
