2. Pay attention to the fabric structure of
the patio umbrella
(patio umbrella)The thickness and tightness of the fabric have a certain impact on its UV resistance. The thicker the fabric, the better the UV resistance, and the tighter the fabric, the stronger the light blocking ability and the smaller the UV transmission.
In addition, we should pay attention to the color of the fabric. According to the test results of the Chinese Academy of metrology, the darker the color of the fabric, the smaller the ultraviolet transmittance and the better the anti ultraviolet performance.
Therefore, when choosing a sunshade, we should fully consider the thickness, tightness and color of the fabric. No matter what brand it is, just follow the above selection method.
3. The price of
the patio umbrella is not directly proportional to the anti ultraviolet effect
The price of
a patio umbrella is not simply determined by the anti ultraviolet effect. It is reported that the high price of some umbrellas is closely related to the umbrella fabric, handle, accessories, umbrella frame material, manufacturing process, packaging and its brand effect. The anti ultraviolet effect is not the main factor in pricing.
