In addition, there is a technical index, usually we call the occlusion rate that is UPF, this value is better than equals 40, its ultraviolet transmittance should be less than or equal to 5%. ”

According to the state of the "Textile Anti-ultraviolet Performance evaluation" provisions, only when the Sun umbrella fabric UPF (UV protection coefficient) value of more than 30, and T (Long-wave Ultraviolet) transmittance of less than 5%, the sun umbrella can be called "Anti-ultraviolet products." If the "sun umbrella" tag is only labeled Anti-ultraviolet, there is no standard coefficient, this kind of umbrella is not known as "Anti-ultraviolet products", its anti-ultraviolet function is also questionable.
