To identify clothing with high sun protection, we first need to understand some fabrics with good sun protection properties. The following are some common sunscreen fabrics and their characteristics:
1. Compact textile fabric: This kind of fabric has high tightness and can effectively block ultraviolet rays. penetrate. Common representative fabrics include tightly woven cotton, linen and nylon. These fabrics often have good sun protection properties and are comfortable and breathable.
2. High-tech sun protection fiber fabrics: Synthetic fibers such as polyester and nylon are often used in professional outdoor sportswear. These fabrics have excellent UV protection properties, are not easily damaged, and have long-lasting UV resistance.
3. Ultraviolet absorber fabric: This type of fabric has ultraviolet absorbers added inside to achieve sun protection by absorbing and converting ultraviolet energy. Commonly used polyester fabrics with UV absorbers added.
To identify clothing with high sun protection, you can adopt the following methods:
1. Check the product label: When purchasing clothing, check whether the sun protection factor or UPF (Ultraviolet Blocking Factor) is marked on the product label. The higher the UPF value, the better the sun protection performance of the clothing.
2. Choose fabrics with higher density: Generally speaking, the higher the density of the fabric, the better the sun protection performance. A preliminary assessment can be made by observing whether the fabric is tightly woven, thick and other characteristics.
3. Pay attention to the color of the fabric: Dark fabrics can attract and absorb more ultraviolet rays, and have relatively better sun protection effects. Therefore, dark-colored clothing tends to have higher levels of sun protection than light-colored clothing.
4. Look for professional certification: Some international certification agencies test and issue certifications for sun protection clothing, such as the Australian standard AS/NZS 4399 standard and the European standard EN 13758 -1 etc. Purchasing certified clothing provides more reliable sun protection.
5. Sunscreen coating: Some special sunscreen clothing is covered with a sunscreen coating, which can block ultraviolet rays. You can observe whether the surface of the clothing has been specially treated.
It should be noted that in addition to the characteristics of the fabric itself, the style, design and wearing style of clothing will also affect the sun protection effect. For example, long sleeves, wide-brimmed hats, etc. can provide better sun protection. Therefore, when choosing sun-protective clothing, consider factors such as fabric quality, UPF value, color, style, etc. to ensure a higher degree of sun protection.
