A sunshade is very different from a sunny umbrella

1、 Different nature
1. Sunny and rainy umbrella: an umbrella used to cover the sun in sunny days and the rain in rainy days. It is an umbrella that can be used in sunny or rainy days. It can not only shade from the sun but also cover the rain.
2. Nature of sunshade: it is mainly used to block the direct sunlight. It can be used in summer to effectively isolate UV damage to the skin.
2、 Different primary uses
1. Primary use of sunny umbrella: sunny umbrella = sunshade + umbrella, but generally, the sunshade effect is slightly weak, and the sunscreen effect is general. If it is dry season, use parasol; In dry areas, use a professional sunscreen umbrella.

2. Primary use of sunshade: it is mainly used to block the direct sunlight. In summer, it can effectively isolate the skin damage caused by ultraviolet rays. Generally, the higher the UPF value, the stronger the UV isolation; The larger the size standard, the larger the area under the solar umbrella.

　　3、 Purchase method of sunshade:
When you buy a sunshade, you should pay attention to whether there is a label in the umbrella that states that the umbrella is UV resistant, that is, the umbrella can really be UV resistant (ordinary umbrellas can not resist UV). Of course, there are also dual-purpose umbrellas on the market with both rain protection and UV resistance. Usually, the label will be sewn on the inside of the umbrella frame, or the price tag will indicate the anti UV effect.
1. When choosing the umbrella surface, the anti ultraviolet function of the umbrella with obviously sparse fabric is generally poor, and customers buy it steadily.
2. Because the fabric has the characteristics of shrinkage, when purchasing sunshade, the umbrella surface should be large rather than small.
3. The color of the fabric is related to the UV protection function. Under the same conditions, the darker the color, the better the anti ultraviolet function of the fabric. In contrast, the anti ultraviolet function of black, navy blue, dark green is better than that of light blue, light pink and light yellow.
4. The anti ultraviolet function can be preliminarily judged according to the fabric properties of the umbrella surface. Generally speaking, cotton, silk, nylon and viscose have poor UV protection function, while polyester is better. It is usually used for making umbrellas, including polyester fabrics, colored Ding cloth, mackintosh cloth, etc. In addition, satin fabrics are better for UV protection. The following are twill and plain fabrics. The darker the color, the better.
