It is called a parasol or sun umbrella.

Parasols, also called sun umbrellas, are umbrellas mainly used to protect against direct sunlight.

The second generation of parasols (also called "nano raincoat umbrellas") is a combination of umbrellas and raincoats. Nano umbrellas have the form of a tri-fold umbrella and a straight umbrella (simply put, There are two choices of long and short umbrellas). Nano raincoats can be transformed from nano umbrellas. Nano raincoats are different from ordinary raincoats because they can guarantee that they will never get wet from head to toe. Because of the nanomaterial, the umbrella can be tossed and dried. After the umbrella is transformed into a raincoat, the raincoat can be completely dried by just wearing it.

Purchase method:

When buying a parasol, pay attention to whether there is a label in the umbrella indicating that the umbrella is UV-resistant, which means that the umbrella can really protect against UV rays. Ultraviolet rays (general umbrellas are actually not resistant to ultraviolet rays). Of course, there are also dual-purpose umbrellas on the market that are both rainproof and UV-resistant. Usually the label will be sewn on the inside of the umbrella's frame, or the anti-UV effect will be indicated on its price tag.

When choosing a parasol, you should refer to the following points:

4. Carefully check the protection level mark before purchasing. The "Evaluation of UV Protection Performance of Textiles" promulgated 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-UV product, and the protection level standard is It 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". When purchasing, consumers should carefully check the protection level mark, and then choose an umbrella that suits them based on local sun exposure conditions.

5. Choose brand-name products and beware of ordinary umbrellas that are passed off as fake anti-UV umbrellas.

6. The UV protection performance can be preliminarily judged based on the fabric properties of the umbrella surface. Generally speaking, cotton, silk, nylon, viscose, etc. have poor UV protection properties, while polyester has better UV protection properties. Polyester-containing fabrics commonly used to make umbrellas include satin, Mccloth, etc. In addition, satin fabric has the best UV protection performance, followed by twill and plain weave. The darker the color, the better.

7. Whether the sunscreen umbrella can protect against ultraviolet rays, the texture of the fabric is not the most important. The main thing is what kind of technical treatment the manufacturer has done on the fabric. Generally, cotton and linen fabrics have certain UV protection properties, but the degree is not strong. Most of the sunscreen umbrellas sold on 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. However, the quality of silver glue varies. The silver glue of sunscreen umbrellas produced by manufacturers with good technical conditions is not easy to fall off, while some cheap sunscreen umbrellas just apply a layer of silver on the umbrella surface in order to make up for it. After being exposed to the sun several times, It lost color.
