In the summer, the sun is scorching, and the business of UV protection umbrellas on the market is also booming. At present, there are many common umbrellas on the market that are used as counterfeit anti-ultraviolet umbrellas. Therefore, consumers should pay attention to the following points when purchasing anti-ultraviolet umbrellas:
1. Check the protection grade mark carefully before purchasing. The “Assessment of Textile Anti-UV Performance” issued by the General Administration of Quality Supervision, Inspection and Quarantine stipulates that only when the UPF (ultraviolet protection factor value) is greater than 30 and the UVA (long wave ultraviolet) transmittance is less than 5%, it can be called an anti-ultraviolet product. The standard is “UPF30+”; when the 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 signs when purchasing, and then choose the umbrella that suits them according to the local sun exposure.
2. Choose brand-name products and beware of counterfeit anti-ultraviolet umbrellas.
3. The anti-ultraviolet performance can be preliminarily judged according to the fabric properties of the umbrella surface. Generally speaking, cotton, silk, nylon, viscose, etc. have poor UV resistance, while polyester is better. Polyester-containing fabrics usually used to make umbrellas include satin cloth, mac cloth, etc. In addition, the anti-ultraviolet performance is best for satin weave fabrics, followed by twill weave and plain weave, the darker the better.
4. Whether the sunscreen umbrella can protect against ultraviolet rays, the texture of the fabric is not the most important thing. The main thing is what kind of technical treatment the manufacturer has done to the fabric. Generally, cotton and linen fabrics have a certain degree of UV protection, but the degree is not strong. In the past two years, most of the sunscreen umbrellas sold on the market are coated with a layer of silver glue on the surface of the umbrella. This treatment can reflect and block some direct ultraviolet rays. However, the quality of silver glue is good or bad. The silver glue of sunscreen umbrellas produced by manufacturers with good technical conditions is not easy to fall off, and some cheap sunscreen umbrellas just coat the surface of the umbrella with a layer of silver in order to refill the number. After several sun exposures It faded.
The sunscreen treatment for light-weight fabrics requires a high technical content, and the cost will be high. At present, only a few umbrella manufacturers such as Tianqi Umbrella Manufacturers have to master this treatment technology. The retail price of an umbrella is more than one hundred yuan, so the cheap and ultra-light sunscreen umbrellas on the market basically cannot achieve the effect of sun protection. Ladies must look for manufacturers and brands when buying such sunscreen umbrellas.
