How To Buy A Parasol
Whenever it is hot summer, there will be many outdoor parasols of different shapes and colors. And many companies will also use sunshades for advertising, but how do you choose when you buy sunshades to get real sunscreen? Let me talk to you about how to buy sunshades?
1. When choosing a sunshade, you should refer to the following points: when choosing an umbrella surface, the umbrella with a significantly sparse fabric textile is generally poor in UV resistance, and consumers should purchase it carefully.
2. Due to the shrinkage characteristics of the fabric, the umbrella surface should be large rather than small when buying shade.
3. The color of the fabric is related to the UV protection performance. Under the same conditions, the darker the fabric, the better the UV resistance. In contrast, black, navy blue, dark green, lighter blue, light pink, and light yellow have better UV resistance.
4. Carefully check the protection level mark before purchasing. According to the "Assessment of UV Protection Performance of Textiles" issued by the General Administration of Quality Supervision, Inspection and Quarantine, only when the UPF (ultraviolet protection coefficient value) is greater than 30, and the UVA (long wave ultraviolet) transmission rate is less than 5%, can it be called an anti-UV product, protection level The standard is "UPF30 +"; when UPF is greater than 50, it indicates that the product has excellent UV protection performance, and the protection level is marked as "UPF50 +". Consumers should carefully check the protection level logo when purchasing, and then choose the umbrella that suits them according to the local sun exposure.
5. Choose brand-name products and beware of ordinary umbrellas that are full of fake and anti-ultraviolet umbrellas.
6. The anti-ultraviolet performance can be preliminarily judged according to the fabric properties of the umbrella surface. In general, cotton, silk, nylon, viscose, etc. have poor UV protection, while polyester is better. Polyester-containing fabrics commonly used for making umbrellas include colored satin cloth and mcbub. In addition, the anti-ultraviolet performance is best with satin weave. The following are twill and plain weave, the darker the better.
7. Whether the sun umbrella can prevent ultraviolet rays, the texture of the fabric is not the most important, and the main manufacturer is what kind of technical treatment the fabric has done. Generally, cotton and linen fabrics have a certain degree of UV protection, but the degree is not strong. Most of the sunscreen umbrellas sold in the market in the past two years were coated with a layer of silver glue on the umbrella surface. This treatment can reflect and block some direct ultraviolet rays.
