How to choose a garden umbrella?

1, pay attention to the anti-ultraviolet performance of the fabric fiber itself

The experimental results show that the UV resistance of dacron fiber is better than that of dacron fiber, and the benzene ring in the molecular structure of dacron fiber has the function of absorbing ultraviolet light. The UV resistance of polyamide fiber, namely the artificial cotton and rayon in nylon glue, is not as good as that of dacron fiber. Therefore, we should try our best to choose polyester fiber as the raw material of the UV umbrella.

2. Pay attention to the organization structure of fabrics

The thickness and tightness of the fabric have a certain effect on its UV resistance. The thicker the fabric, the better the UV resistance, and the tighter the fabric, the stronger the light blocking ability, the smaller the UV transmission.

Another thing to pay attention to is the color of the fabric. According to the test results of the Chinese Institute of Metrology, the darker the color of the fabric, the smaller the UV transmittance and the better the UV protection performance.

Therefore, we should fully consider the thickness, tightness and color of the fabric when choosing the parasol. No matter what brand it is, just follow the above selection method.

3, the price is not proportional to the effect of UV resistance

The price of a parasol is not simply determined by the effect of UV resistance. According to reports, some sunshade price is high, and umbrella fabric, handle, accessories, umbrella material, production process, packaging and its brand effect are very related, anti-ultraviolet effect is not the main factor of pricing.
