Sunburn: How to protect textiles well?

Sunscreen can be troublesome and does not always protect the skin enough. There is an alternative sometimes more durable and safer: the fabric. What he promises and what he enjoys

Black clothes protect better from the sun than from white

In principle, all finely woven textiles protected against solar radiation. However, there are differences: the sun protection factor is high, the more the wires are intertwined. Since synthetic fibers are thinner than cotton, synthetic fiber textiles such as polyester generally have a superior protective effect. In addition, the color does not matter. White clothes do not heat up in the sun. But there is still about 40% of the harmful UV rays on the skin. Black clothes heat up, but at the same time absorb about 97% of the radiation.

UV protective clothing with UPF and UV standard 801

At the same time, some manufacturers offer clothing with special protection against UV rays, especially in children's clothing. This protection is obtained mainly with fiber type and dense weaving, and rarely with special chemical equipment. Since some manufacturers pay well for UV protection, potential buyers need to pay attention to a significant standard.

An Australian standard is the UPF (Ultraviolet Protection Factor). It is comparable to the sun protection factor of sunscreen. This means that textiles with UPF 30 allow us to stay 30 times longer in the sun than without protection. However, the figure does not say whether this sun protection factor is actually observed under practical conditions. For example, in heavy use or when it is wet. The same goes for the European standard EN-13758.

The 801 standard UV quality label is more reliable. According to this standard, the garments tested keep their promise, even if they are wet, stretched or washed several times, for example. In each case, only the lowest value of a textile obtained is certified.
