What color parasol can protect against UV rays?

Nowadays, parasols are colorful and have various patterns and fabrics, but can they all provide good sun protection? First of all, you need to confirm whether it is a parasol. Generally speaking, there is a layer of silver glue on the surface or inside of the umbrella, which is not transparent when facing the sun. There is also a protection tag.

It means it is a parasol. Secondly, the color of the parasol is related to the strength of its UV protection. The darker the color, the higher the UV protection performance. For example, black and dark blue are better than light colors. At the same time, a high protection value on the label also indicates good UV protection.

When the fabric is the same, dark-colored umbrellas have better UV protection effects. The biggest difference between parasols and other umbrellas is that they have an anti-UV coating to prevent the penetration of ultraviolet rays. Therefore, dark-colored parasols are the most sun-protective.

In addition to choosing a parasol based on color, you can also choose from various aspects such as fabric. Look at the fabric. The thicker the umbrella surface, the tighter the fabric, the better the UV resistance. Compared with cotton, silk, nylon and other fabrics, polyester is more sun-proof. If you want to know how effective a parasol is in protecting you from the sun, try it out in the sun. Umbrellas with darker shadows and lower light transmittance have the best sun protection effect. Also, read the label. It mainly depends on the protection index, that is, the UPF and UVA values. Only when the UPF is greater than 40 and the UVA transmittance is less than 5%, can it be called an anti-UV product. The larger the UPF value, the better its anti-UV performance. Generally, most products on the market are marked as "UPF50+", which means their protection is sufficient.

In addition, the fabric of the parasol is also very important. If the umbrella is made of cotton or nylon, the anti-UV effect will be much worse. This is mainly because these fabrics absorb ultraviolet rays. The better anti-UV fabric is satin fabric, which is dense and not sparse. In addition, it is best not to wash the parasol with water to prevent the coating on the fabric from being washed off and losing its UV protection effect.
