According to the national standard "Evaluation of Anti-ultraviolet Performance of Textiles", only the UPF (Ultraviolet Protection Coefficient) is greater than 30 and the UVA (Long Wave Ultraviolet) transmittance is less than 5% can it be called an anti-ultraviolet product, and the protection grade standard is "UPF 30+"; When the UPF is greater than 50, it shows that the product has excellent anti-ultraviolet performance, and the protection level is marked as "UPF50++". Consumers should carefully check the protection level mark when purchasing.
Zhang Jianping also reminded consumers that in view of the situation that ordinary sun umbrellas pretend to be anti-ultraviolet umbrellas in the market, consumers are more at ease in choosing brand-name products. Secondly, according to the fabric characteristics, it can also be preliminarily identified. Generally speaking, cotton, silk, nylon and viscose have poor ultraviolet resistance, while polyester is better.
How to tell whether it is anti-ultraviolet?
When buying an umbrella, you should pay attention to whether there is a label in the umbrella indicating that the umbrella is UV-proof, which means that the umbrella is really UV-proof (ordinary umbrellas are actually UV-proof). Of course, there are also dual-purpose umbrellas that are both rain-proof and ultraviolet-proof. Usually the label will be sewn on the inside of the umbrella near the skeleton, or the price tag will indicate the anti-ultraviolet effect.
Why are the prices of two umbrellas so different (20-500 yuan)?
The high price of some parasols is closely related to the fabric, handle, accessories, umbrella frame material, manufacturing technology, packaging and brand effect, and the anti-ultraviolet effect is not the main factor in pricing. Take fabrics as an example. At present, in addition to the past silver glue and pearl glue, there are also new fabrics such as mouth Mike cloth, silver onion satin cloth and knock-on cloth. These new fabrics can not only resist ultraviolet rays, but also have good visual effects. However, in terms of anti-ultraviolet effect, high-quality silver glue with relatively low price is actually the best.
The cost of UV protection umbrella should be at least 16 yuan.
A qualified anti-ultraviolet sunshade, even if it is made of the most common fabric and woven by high-density technology, should at least be 16 yuan (subject to a big group like Paradise Umbrella Industry). And those so-called umbrellas that cost more than ten yuan or even several yuan are obviously counterfeit products. They just coated the ordinary umbrella with a layer of inferior reflective paint, which naturally failed to achieve the anti-ultraviolet effect. In addition, the skeleton of genuine sunshade is made of steel or aluminum, which is very strong; The skeleton of the fake umbrella is made of some scrap iron, and it will break in a few times.
How to choose a sunshade?
1. When choosing an umbrella cover, the ultraviolet protection performance of umbrellas with obviously sparse fabrics is generally poor, so consumers should buy them carefully.
2. Because the fabric has the characteristic of shrinking, when buying a parasol, the umbrella cover should be large rather than small.
3. The color of the fabric is related to the anti-ultraviolet performance. Under the same conditions, the darker the color, the better the ultraviolet resistance of the fabric. In contrast, black, navy blue, dark green and light blue, light pink and light yellow have better ultraviolet resistance.
4. Before purchasing, carefully check the protection grade mark. The Evaluation of Anti-ultraviolet Performance of Textiles issued by the General Administration of Quality Supervision, Inspection and Quarantine stipulates that only when UPF (Ultraviolet Protection Coefficient) is greater than 30 and UVA (Long Wave Ultraviolet) transmittance is less than 5% can it be called anti-ultraviolet products, and the protection grade standard is "UPF 30+"; When the UPF is greater than 50, it shows that the product has excellent anti-ultraviolet performance, and the protection level is marked as "UPF50++". When purchasing, consumers should carefully check the protection grade mark, and then choose the umbrella that suits them according to the local sun exposure.
5, choose brand-name products, beware of ordinary umbrellas and counterfeit anti-ultraviolet umbrellas.
6. According to the fabric performance of the umbrella cover, its ultraviolet resistance can be preliminarily judged. Generally speaking, cotton, silk, nylon and viscose have poor ultraviolet resistance, while polyester is better. The fabrics containing polyester commonly used for making umbrellas are satin cloth, Mike cloth and so on. In addition, satin fabric has the best UV protection, followed by twill and plain weave, and the darker the color, the better.
7. Whether the sun umbrella can prevent ultraviolet rays, the texture of the fabric is not the most important, what matters is what kind of technical treatment the manufacturer has done on the fabric. General cotton and linen fabrics have certain anti-ultraviolet performance, but the degree is not strong. In the past two years, most sun protection umbrellas sold in the market have been coated with a layer of silver glue, which can reflect and block some direct ultraviolet rays. However, the quality of silver glue is good or bad, and the silver glue produced by manufacturers with good technical conditions is not easy to fall off, while some cheap sun umbrellas just coat a layer of silver on their umbrellas to make up for it, which will fade after several sun exposures.
Special reminder
When the umbrella is wet, due to the light conduction of water, the ultraviolet transmittance increases and the protective effect decreases. Therefore, wet umbrellas are not suitable for ultraviolet protection.
Why is the paradise umbrella especially able to prevent ultraviolet rays?
In view of the increasingly serious harm of ultraviolet rays to human body, Hangzhou Paradise Umbrella Group is in urgent need of users, and specially employs senior scientific researchers to cooperate with many domestic universities, research institutes and manufacturers to carefully select fabrics, such as silver glue, satin, pearl glue, impact cloth and TC cloth. These fabrics are woven by high-density technology, which makes the molecular spacing of fabrics extremely dense. At the same time, the coating is mixed with ultrafine particles, which will scatter ultraviolet rays. After more than a year and hundreds of repeated experiments, a special anti-ultraviolet technology-anti-ultraviolet recoating technology, formula and coating method was finally developed. At present, the technology has applied for a national patent (application number: 01112868.2). It can be said that the special processing technology is the most critical factor for the excellent anti-ultraviolet performance of Paradise Umbrella products. The anti-ultraviolet canopy of paradise umbrella has passed the strict anti-ultraviolet test of China Institute of Metrology, and has excellent anti-ultraviolet performance, and the protection level has reached UPF 50++.
The summer sun is like fire, and all kinds of anti-ultraviolet umbrellas come in droves on the market. Experts from China Consumers Association remind consumers that it is "learned" to buy an anti-ultraviolet umbrella.
The expert revealed that the national standard "Evaluation of Anti-ultraviolet Performance of Textiles" has passed the examination and approval not long ago and will soon be promulgated by the AQSIQ. The standard stipulates that only when UPF (ultraviolet protection coefficient) is greater than 30 and UVA (long-wave ultraviolet) transmittance is less than 5% can it be called ultraviolet protection product, and the protection grade standard is "UPF 30+"; When the UPF is greater than 50, it shows that the product has excellent anti-ultraviolet performance, and the protection level is marked as "UPF50++". At present, the UPF of anti-ultraviolet umbrellas on the market is generally 30 to 40, and only a few brands such as Paradise brand have reached 50+. When purchasing, consumers should carefully check the protection grade mark, and then choose the umbrella that suits them according to the local sun exposure.
In view of the situation that some ordinary umbrellas on the market are shoddy and counterfeit anti-ultraviolet umbrellas, the expert reminded that brand-name products should be selected first; Secondly, the anti-ultraviolet performance can be preliminarily judged according to the fabric performance of the umbrella cover. Generally speaking, cotton, silk, nylon and viscose have poor ultraviolet resistance, while polyester is better. The polyester-containing fabrics commonly used to make umbrellas include satin cloth, Mike cloth, impact-resistant cloth and so on. Some consumers think that the thick umbrella cover has good anti-ultraviolet performance, but it is not. In order to make umbrellas lightweight, some enterprises such as Paradise Umbrella have developed very thin but very compact fabrics, and their protective performance is far superior to ordinary fabrics. In addition, satin fabric has the best ultraviolet resistance, followed by twill and plain weave; The darker the color, the better.
