Choice Of Small Sun Umbrella

The choice of anti-ultraviolet umbrella mainly depends on the fabric of the umbrella. The research shows that the fabric with thick umbrella surface has better anti-ultraviolet performance than that with thin umbrella surface. Generally speaking, the anti-ultraviolet effect of cotton, silk, nylon, viscose and other fabrics is poor, while polyester is better; Some consumers believe that the thicker the umbrella surface, the better the anti-ultraviolet performance, in fact, such as the paradise umbrella series has developed a thin but very tight fabric, the protective performance is far better than the general fabric; In addition, the darker the color of UV resistance, the better, with satin fabric the best, followed by twill, plain.
Experts also remind consumers to recognize the UV protection performance label. The upcoming national standard stipulates that only when the UPF is > 30 and the transmission rate of UVA is less than 5%, it can be called anti-ultraviolet products, and the protection grade is labeled UPF30+; When UPF > 50, it indicates that the UV protection performance of the product is excellent, and the protection grade is labeled UPF50+.
