Summer has arrived. Buy a sun umbrella or a parasol for sun protection?

A sun umbrella is an umbrella used to shade the sun in sunny days and keep out the rain in rainy days. It is a kind of umbrella that can be used for both sunny and rainy purposes, which can not only shade the sun but also cover the rain. Generally, it is a light-colored umbrella, which has the function of sun protection, that is to say, it can shade the sun in sunny days, shelter the rain in rainy days, and it is universal in sunny days and rainy days. Under normal circumstances, the sun umbrella is light in color, and the commonly used umbrella fabrics are emery cloth, silver tape, fat silk, pearl tape, yarn-dyed fabric and so on. A parasol, also called a sun umbrella, refers to an umbrella used to keep out the direct sunlight. The main function of sunshade is to prevent sun, block ultraviolet rays, resist the harm of ultraviolet rays to the skin, and effectively isolate the harm of ultraviolet rays to the skin. Umbrella cloth is usually made of anti-ultraviolet fabric or coated with anti-ultraviolet coating.

The difference between a sun umbrella and a sunshade is mainly reflected in its functionality. To put it simply, although sunny umbrellas are common in sunny and rainy days, the sun protection effect is still worse than that of professional umbrellas. If your area is rainy, a parasol can basically meet the sun protection needs. However, if your area is arid, it is recommended that you choose a professional sunscreen umbrella, so that the sunscreen effect is more ideal.

A parasol can be used to keep out the rain, but can a parasol keep out the umbrella? Actually, parasols should not be used as umbrellas. Although the umbrella has a certain rainproof function, if it is used for a long time, the acidic and alkaline substances in the rain will lead to the aging of the anti-ultraviolet coating on the umbrella, thus affecting the sunshade effect. When it rains heavily, some poor quality sun-shading and ultraviolet-proof coatings are not up to standard, which may easily lead to the damage of the coatings, resulting in their no longer having ultraviolet-proof performance. So I suggest you prepare two umbrellas at any time in case of emergency.

When buying a parasol, you should pay attention to whether there is a label inside the umbrella indicating that the umbrella is UV-proof, that is, the umbrella is really UV-proof (ordinary umbrellas are actually UV-proof). Of course, there are also dual-purpose umbrellas that are both rain-proof and ultraviolet-proof. Usually the label will be sewn near the inside of the umbrella frame, or the price tag will indicate the anti-ultraviolet effect.

When choosing a sunshade, you should refer to the following points:

When choosing an umbrella cover, the ultraviolet protection performance of umbrellas with obviously sparse fabrics is generally poor, so consumers should buy them carefully.

Because the fabric has the characteristic of shrinking, when buying a sunshade, the umbrella cover should be large rather than small.

The color of fabric is related to its anti-ultraviolet performance. Under the same conditions, the darker the color, the better the ultraviolet resistance of the fabric. In contrast, black, navy blue, dark green and light blue, light pink and light yellow have better ultraviolet resistance. [ 1]

4. Before purchasing, carefully check the protection grade mark. The Evaluation of Anti-ultraviolet Performance of Textiles issued by the General Administration of Quality Supervision, Inspection and Quarantine stipulates that only when UPF (Ultraviolet Protection Coefficient) is greater than 30 and UVA (Long Wave Ultraviolet) transmittance is less than 5% can it be called anti-ultraviolet products, and the protection grade standard is "UPF 30+"; When the UPF is greater than 50, it shows that the product has excellent anti-ultraviolet performance, and the protection level is marked as "UPF50+". When purchasing, consumers should carefully check the protection grade mark, and then choose the umbrella that suits them according to the local sun exposure.
