UV absorber UV-327: Invisible “sunscreen umbrella” for textiles

On sunny days, we often lament the gifts of nature, but we also need to be wary of the potential harm of ultraviolet rays to skin and clothing. In order to protect people from ultraviolet rays, scientists have developed a magical chemical substance – the ultraviolet absorber UV-327. It is like an invisible “sun protection umbrella”, providing strong UV protection capabilities for textiles. This article will explore in-depth the characteristics, applications of UV-327 and how to improve the UV resistance of textiles.

What is UV absorber UV-327?

UV absorber UV-327 is a high-performance ultraviolet light stabilizer and belongs to benzotriazole compounds. Its main function is to prevent the aging of polymer materials by absorbing ultraviolet rays, thereby extending the service life of the product. UV-327 has excellent heat resistance, weather resistance and good compatibility with polymers, and is widely used in plastics, coatings, inks and textiles.

Application of UV-327 in textiles

With people’s awareness of health and environmental protection, the functionalization of textiles has become a new trend in the development of the industry. UV-327 has been widely used in the textile field due to its excellent ultraviolet protection performance. By adding it to the fabric, it not only effectively blocks UV rays, but also maintains the original softness and comfort of the fabric.

Improve UV protection capabilities of textiles

After UV-327 treatment, the ultraviolet protection coefficient (UPF) of textiles is significantly improved. UPF refers to the degree to which ultraviolet rays are weakened when they pass through fabrics. The higher the value, the better the protection effect. For example,The UPF value of ordinary cotton fabrics processed may be only about 10, while the UPF value of textiles using UV-327 can reach 50+, which means that more than 98% of the UV rays are blocked out.

Comparison table before and after UV-327 processing

Test items	Unhandled fabric	UV-327 treatment fabric
UPF value	10	50+
Color Change	Obvious fading	Last color
Material Strength	Easy to brittle crack	Strength is maintained well

Progress in domestic and foreign research

In recent years, domestic and foreign scholars have conducted a lot of research on the application of UV-327 in textiles. Research shows that UV-327 can not only effectively improve the ultraviolet protection capability of textiles, but also delay color fading and physical performance degradation caused by ultraviolet irradiation.

Domestic Research: An experiment from an institute of the Chinese Academy of Sciences showed that after three months of continuous exposure to strong ultraviolet light, its fracture strength decreased by only 5%, far lower than 30% of the untreated samples.
International Research: A paper published by DuPont in the United States pointed out that when used with other additives, UV-327 can provide more comprehensive protection without changing the feel of the fabric.

Conclusion

To sum up, UV absorber UV-327, as a star product in the textile field, has won the favor of the market for its efficient UV protection ability and excellent stability. Whether it is daily wear or outdoor sports equipment, the UV-327 can provide users with reliable protection. In the future, with the advancement of technology and the growth of demand, I believe that UV-327 will show its unique charm in more fields and become an important tool for humans to fight against the threat of ultraviolet rays. Let us look forward to more exciting performances brought by this invisible “sunscreen umbrella”!
