Sunscreen clothing can play a role in sun protection. The function of sunscreen clothing mainly depends on the materials used. The common fabrics of sunscreen skin clothing mainly include nylon, polyester and nylon polyester, among which nylon fabric has the best quality and relatively high price. Then the lower the price, the weaker the sunscreen effect, but it can still be sunscreen.
The anti-ultraviolet function of most sun protection clothes is mainly realized by coating, but the coating has good air permeability, which makes it difficult for ultraviolet rays to penetrate, so some sun protection clothes have poor air permeability. In fact, the fiber composition of textile fabrics, the density and thickness of texture, the depth of color and so on. , will have a certain impact on the anti-ultraviolet performance. Therefore, generally speaking, the same clothing, dark color is better than light color, thick fabric is better than thin fabric, tight fabric structure is better than loose fabric.
Matters needing attention in purchasing sunscreen clothing
1, look at the label
Look at the label. Regular anti-ultraviolet products should be marked with national standard number and UPF value. If the measured value of UPF is greater than 30 and the transmittance of UVA is less than 5%, it is marked as 30.
Step 2 look at additives
Titanium dioxide sunscreen is added to cotton sunscreen clothing and skin sunscreen clothing. Sleeve sun protection clothes have no sun protection at all. "Leather clothes" have more sunscreen than cotton, that is, the sunscreen effect is better.
Step 3 look at the materials
The fabric of high-quality sunscreen clothing is light and breathable, and the permeability of sunscreen clothing is also a factor to be considered when purchasing.
4. Look at this color
Crimson and navy are bigger than other colors. It is worth reminding that light-colored clothes have poor anti-ultraviolet ability, especially those dazzling white cotton clothes, which often contain fluorescent whitening agents.
