UV fabric can withstand UV light or not? How much ultraviolet light can resist?
At present, there is no uniform testing standard in China. However, there is a simple and effective method to cover the outdoor umbrella fabric on the UV light source: put a new version of RMB 100 under the outdoor umbrella, if the word“100” of the UV anti-counterfeiting label cannot be seen or is not visible, indicating that the outdoor umbrella fabric can prevent ultraviolet light, otherwise it is not anti- or completely defenseless.
