You'Ve Been Cheated! Sunscreen Clothes Are Not As Expensive As Possible.

Under a hot day, a light, beautiful and sunscreen.

It is the summer necessity of many citizens.

However, it was found that most of the sunscreen clothing sold on the market did not specify the UPF value (UV protection index) according to the regulations, and the quality and quality of the sunscreen were uneven.

More experiments show that the price of counterfeit sunscreen clothing is several times higher than that of ordinary shirts, but the effect of sunscreen is not necessarily stronger than that of dark shirts.

According to the reporter's visit, whether it's in a brand store or a clothing store on the street, this kind of sunscreen suits with plastic, pparent and bright colors are sold, ranging from 3 to 50 yuan to several hundred yuan.

These "

"The material is not the same, most of which are mainly polyester, and some are nylon, and the sunscreen clothing is the" nano coating ".

Is there any specific index for the sun protection performance? A reporter's enquiry revealed that in 2011, China launched the latest assessment standard, "the evaluation of ultraviolet radiation resistance of textiles", which expressly provides that only when

When the UPF value is greater than 40, and the pmittance of UVA (the most penetrating ultraviolet) is less than 5%, it can be called "anti ultraviolet product". The higher the UPF value, the better the sunscreen effect.

Normal

There are three requirements for the tag: one is to require the commodity to mark the UPF value on the tag, and the two is to ask the consumer to remind consumers that the protective performance of the product may be reduced if it is used for a long time and under tensile or humid conditions.

Finally, it is necessary to indicate that the standard used for testing the clothing is the evaluation of the ultraviolet radiation resistance of textiles, and the number of the evaluation standard should be given on the tag.

However, yesterday, reporters visited twenty "sunscreen clothing" counters found that there are 80% "

"There is no clear sun protection parameter on the label.

Spot check: nearly 80% sunscreen clothes are not UV protected.

In July last year, the Jiangsu Quality Supervision Bureau released the "quality control report on inspection and inspection of anti ultraviolet clothing in 2015". A total of 82 batches of samples were selected, and the compliance rate of "anti ultraviolet products" was only 26.8%, nearly 80%.

No UV protection function.

The sample accords with the requirement of permeability is 31 batches, with a coincidence rate of 37.8%, while 5 batches with better UV protection and better air permeability account for 6.1%.

Reporters learned that the general fabric is to increase the coating to play the role of UV protection, the thicker the coating, the better the UV protection effect, but the increase of coating will lead to poor permeability of the clothes, easy to feel bored.

In addition, washing will also reduce the UV protection index of sunscreen clothing.

Experiment: cotton T-shirt sunscreen effect is not bad.

Ye Linhua, an associate professor of Optics Research Institute of Zhejiang University, has tested three kinds of sunscreen clothes, the first is orange.

Sunscreen clothing is not the same as ordinary cardigan.

The second is sunscreen suits that look like ultra-thin plastic raincoats.

The third one is a white high grade sunscreen suit with a slightly higher price.

Three sunscreen suits were tested under the single layer condition. The results of the first two measurements showed that the UVB pmittance reached 12% and third pieces were 28%, which exceeded the 5% stipulated by the state.

Take three pieces.

The test results show that the pmission rate of UVB has decreased by more than half.

One of the most common cotton white T-shirts found at random is only one layer of fabric, and the UVB pmittance is only 7%.
