Can a sun umbrella be used as a rain umbrella?

I believe that many ladies have such questions, the sun umbrella is basically the same material and workmanship as the ordinary umbrella. So can the sun umbrella be used as rain umbrella? The answer is yes, most parasols can be used as rain umbrellas.


The sun umbrella is actually a replica of the umbrella. The biggest difference from the traditional umbrella is that the sun umbrella uses an anti-UV umbrella cloth, mainly looking at the fabric of the umbrella. The general umbrella uses ordinary waterproof fabric. Therefore, judging whether a sun umbrella can be used as rain umbrella is mainly determined by the fabric of the sun umbrella.


According to the National "Assessment of UV Protection Performance of Textiles", only UPF (UV protection coefficient value) is larger than 30, and UVA (long-wave ultraviolet) transmittance is less than 5%, which can be called UV protection products, and the protection grade standard is "UPF30+"; When the UPF is larger than 50, it indicates that the product has excellent UV protection and the protection rating is “UPF50+”. However, the UPF of UV protection umbrellas on the market today is generally only between 30 and 40.


Among many fabrics, thicker fabrics umbrellas have better UV resistance than thin ones. Generally speaking, cotton, silk, nylon, viscose and other fabrics have poor UV protection, while polyester is better; therefore, most of the sun umbrellas are mainly made of polyester fabric, and polyester fabric is also the main fabric for making ordinary rain umbrellas. Therefore, most sun umbrellas can be used as rain umbrellas.


In addition, there are a lot of silver plastic anti-UV umbrellas on the market. The special coating of this kind of sun umbrella does have sun protection function, but because the "film" is relatively delicate, it is easy to change color and fall off under the sun exposure, and the corrosion effect of rainwater also will make it lose its sun protection function and shorten its service life. It is not suitable for use as a rain umbrella. So if the sun umbrella you buy is a silver coating umbrella and the silver is applied to the outside surface of the umbrella, it is recommended that you do not use it as a rain umbrella.


According to the above, we know that the sun umbrella used for daily use can be used as a rain umbrella. The only drawback is that it is more troublesome to organize: After the sun umbrella is used in rainy days, it must be placed in a ventilated place to dry. Of course, you can also buy two different styles of umbrella for sun protection and rain protection.
