There are two kinds of umbrellas: ladies' umbrellas and men's umbrellas, which are made of cotton, silk, nylon, polyester and viscose.

women's umbrellas are mostly in pink, purple, ice green, light blue, and light colors, while men's umbrellas are more business-oriented, such as black, navy blue, dark green and dark red.

Generally speaking, umbrellas made of cotton, silk, nylon and viscose have poor ultraviolet protection performance, while polyester is better. The polyester-containing fabrics commonly used to make umbrellas are satin cloth, Mike cloth and so on. In addition, satin fabric is the best anti-ultraviolet performance, followed by twill and plain, and the darker the color, the better.

Whether the sun umbrella can prevent ultraviolet rays is not the most important, but mainly depends on what kind of technical treatment the manufacturer has made on the fabric. Generally, cotton and hemp fabrics have certain anti-ultraviolet performance, but the degree is not strong.

in the past two years, most sun protection umbrellas sold in the market were coated with a layer of silver glue, which can reflect and block some direct ultraviolet rays. However, the quality of silver glue is good or bad, and the silver glue produced by manufacturers with good technical conditions is not easy to fall off, while some cheap sun umbrellas only paint the umbrella with a layer of silver in order to make up for it, and the color will fade after several times of sunshine exposure.

When the umbrella is wet, due to the optical conduction of water, the ultraviolet transmittance increases and the protective effect decreases. Therefore, wet umbrella is not suitable for ultraviolet protection.
