Which brand of anti-ultraviolet sun umbrella is good?

Throughout the year, as long as the weather is fine, the sun will emit ultraviolet rays. When women go out, they often take protective measures not to absorb too much ultraviolet rays. One of the protective measures is to take a sun umbrella that protects against ultraviolet rays. At present, there are many kinds of anti-ultraviolet sun umbrellas on the market, and the prices are basically above 100 yuan. Generally speaking, the quality of anti-ultraviolet sun umbrellas bought for tens of dollars is not very good, so it is necessary to identify the brand when buying them.

3. Hongye brand anti-ultraviolet sun umbrella

The umbrella cover of Hongye brand sun umbrella adopts a unique fabric, and metal fibers are sewn in the fabric, which makes the fabric have higher radiation and ultraviolet resistance, and also has the ability of absorbing heat, so that people can enjoy the cool feeling under the umbrella. The red-leaf sun umbrella will not deform when folded repeatedly, which keeps the beauty of the umbrella surface and can remove the odor without interference from the odor.

Function of sun umbrella material

1. Ultraviolet resistance of fabric fiber itself

Experiments show that among untreated fibers, polyester fiber has the best ultraviolet resistance, and benzene ring in the molecular structure of polyester fiber has the function of absorbing ultraviolet rays. Nylon in chemical fiber, that is, rayon and rayon in nylon glue, has ultraviolet resistance, but it is not as good as polyester. Therefore, the raw material of sunshade determines that it has the function of preventing ultraviolet rays.

2. Fabric structure

The thickness and density of fabric have certain influence on its ultraviolet resistance. The thicker the fabric, the better the ultraviolet resistance, the tighter the fabric, the stronger the light blocking ability and the smaller the ultraviolet transmittance.

3. The color of the fabric

According to the test results of China Institute of Metrology, the color of the fabric also plays a certain role in blocking ultraviolet rays. The deeper, the smaller the ultraviolet transmittance, and the better the anti-ultraviolet performance. Generally, dark umbrella cloth can block 95% UVA. Under the same conditions, the darker the color of the fabric, the better the ultraviolet resistance. In contrast, black, navy, dark green, light blue, light pink, light yellow and other anti-ultraviolet effects are good.

How to tell whether a sun umbrella is UV-proof?

Shading coating

The adhesive layer is related to the sunscreen effect. Black umbrella > colored plastic umbrella > silver umbrella > non-plastic umbrella >: lace hollow umbrella//multilayer plastic umbrella > one or two layers of plastic umbrella > non-plastic umbrella >: lace hollow umbrella//dark umbrella > light umbrella

UPF value label

The anti-ultraviolet umbrella should be marked with the sun protection index (UV mark), and the UPF value will be marked on the tag. When UPF=30, ultraviolet filtration =95%. When UPF value =50, ultraviolet filtration =99.8% or above. But there are few umbrellas that can really achieve UPF50, and it is not easy to buy. Generally speaking, an umbrella with UPF value of 30 is enough for daily sun protection in non-high ultraviolet areas.

Fabric density

Density is not thickness, and a thick umbrella surface may not have a good shading effect. Under the same fabric, the denser the fabric, the lower the light transmittance, and the less ultraviolet rays come in through the umbrella.

Fabric: PG cloth has the best effect.

The fabrics used to make general umbrellas in the market mainly include Tylenol, PG cloth and nylon.

Umbrella fabrics with sun protection function mainly include PG cloth, black tape, colored tape, silver tape, pearlescent cloth, nylon, polyester and so on.

PG cloth (also called "bumping cloth"): It belongs to the first-class umbrella cloth, which is thicker and more expensive, and has better anti-ultraviolet effect. The only drawback is that it is expensive.

Black tape: stable, good anti-ultraviolet performance, not easy to fall off, shading and heat insulation. The price is relatively close to the people and cost-effective. Suggest starting.

Color adhesive tape: Generally, color adhesive is coated on the outside, combined with black polyester cloth, which can basically achieve zero light transmission and strong ultraviolet resistance. The disadvantage is that it is expensive and it is not easy to print colors or patterns.

Silver tape: It has a good anti-ultraviolet function, but after a long time of use, the silver glue is easy to separate from the folded place.

Pearlescent cloth: Pearlescent cloth has bright colors, thin umbrella body and various styles, which are deeply loved by ladies, but the anti-ultraviolet effect is not ideal. For real sun protection, it is not recommended for expectant mothers to buy parasols made of pearlescent fabrics.

Nylon: Also known as nylon. Nylon cloth itself is subdivided into many kinds. Umbrella cloth has good elasticity and wear resistance, but it is not ideal for shading. If it is matched with silver glue or pearl glue, it has the effect of preventing ultraviolet rays.

Polyester: economical umbrella with rough fabric and low price. Almost all common embroidered umbrellas are made of this fabric, which is exquisite and beautiful. Unfortunately, one is not durable and the other is not sun-proof, especially for large-scale embroidery, hollowing out and tulle.

The three brands of UV-proof sun umbrellas launched by Bian Xiao should be the leading brands in the domestic sun umbrella industry. In the industry market of anti-ultraviolet umbrellas, they account for the vast majority of sales, and people are more willing to buy these three brands when choosing anti-ultraviolet umbrellas. At present, the anti-ultraviolet sun umbrella sold in the market not only has the anti-ultraviolet function, but also can shelter from the wind and rain in rainy days.
