How to distinguish the authenticity of paradise umbrella
1, before purchase, you should carefully look at the protection class mark. According to the “Accreditation of UV Protective Properties of Textiles†promulgated by the General Administration of Quality Supervision, Inspection and Quarantine (AQSIQ), only when the UPF (UV protection factor value) is greater than 30 and the UVA (long-wavelength ultraviolet) transmittance is less than 5, it can be referred to as a UV protection product. It is “UPF30+â€; when UPF is greater than 50, it indicates that the product has excellent UV protection, and the protection class is identified as “UPF50+â€. Consumers should carefully check the protection class mark when purchasing, and then choose the umbrella suitable for them according to the local sun conditions.
2, choose brand-name products, beware of ordinary umbrella full of counterfeit anti-ultraviolet umbrella.
3, according to the nature of the umbrella surface fabric to determine the initial UV protection performance. In general, cotton, silk, nylon, viscose, etc. have poor UV protection performance, but polyester is better. The polyester-containing fabrics that are commonly used for making umbrellas are colored lining cloths, micro cloths, and the like. In addition, the best anti-ultraviolet properties are satin fabrics, followed by twill and plain weave, and the darker the better.
4, sun protection umbrella can not prevent UV, fabric texture is not the most important, the main manufacturers also do what kind of technical treatment of the fabric. General cotton, linen texture itself has a certain degree of UV protection, but the degree is not strong enough. Sun umbrellas sold on the market in the past two years were mostly coated with a layer of silver glue on the surface of the umbrella. Such treatment can reflect and block some direct ultraviolet rays. However, the quality of silver plastic is good and bad, sunscreen silver plastic products produced by manufacturers with good technical conditions are not easy to fall off, and some inexpensive sun umbrellas are filled with silver, after several times of sun exposure. I lost it.
Sunscreen treatment for light-weight fabrics requires high technical content and high costs. At present, as long as a few manufacturers such as Paradise umbrella grasp this processing technology. The retail price of an umbrella is more than one hundred yuan, so the cheap ultra-light sun umbrellas sold on the market can hardly reach the effect of sun protection. Ladies must look for manufacturers and brands when purchasing such sun umbrellas.
