How to choose a parasol?

Parasol are also called sun protection umbrellas, which are mainly used to block direct sunlight.

Choosing an anti-ultraviolet umbrella mainly depends on the fabric of the umbrella. Studies have shown that thick fabrics have better anti-ultraviolet performance than thin ones. Generally speaking, cotton, silk, nylon, viscose and other fabrics have poor anti-ultraviolet effects, while polyester is better; some people think that the thicker the umbrella, the better the anti-ultraviolet performance, but this is not the case. Some companies have developed a thin but very tight fabric with far better protection than general fabrics; in addition, the darker the color of the anti-ultraviolet performance, the better, with satin fabric being the best, followed by twill and plain weave.

Relevant experts also remind consumers to recognize the anti-ultraviolet performance logo. Domestic and foreign standards generally use UPF values, that is, ultraviolet protection factor values, to evaluate the anti-ultraviolet performance of textiles. The UPF value is the ratio of the average radiation amount of ultraviolet rays to unprotected skin. The larger the UPF value, the better the anti-ultraviolet performance. The national standard to be issued soon stipulates that only when UPF is greater than 30 and the UVA transmittance is less than 5%, it can be called an anti-ultraviolet product, and the protection level is marked as UPF30+; when UPF is greater than 50, it indicates that the product has excellent ultraviolet protection performance, and the protection level is marked as UPF50+.

In the sun protection product market this summer, anti-ultraviolet sun umbrellas are very popular. When choosing an anti-ultraviolet sun umbrella, consumers should understand its characteristics so that they can choose a good umbrella that satisfies them from appearance to quality.
