In recent decades, human activities—particularly the increased use of chlorofluorocarbons (CFCs) like Freon—have caused significant damage to the Earth's ozone layer. This depletion has led to a sharp rise in ultraviolet (UV) radiation reaching the Earth's surface, contributing to a growing number of skin cancer cases and posing serious threats to public health.
To address this issue, the national standard GB/T 18830-2009 was introduced, which defines UV-protective textiles. According to this regulation, fabrics with a UV Protection Factor (UPF) greater than 40 and a UV transmission rate (UVA) below 5% can be classified as UV protection products. These textiles help reduce or prevent harmful UV exposure, offering essential protection for people who spend time outdoors.
Currently, there are two main approaches to producing UV-resistant textiles:
(1) Using UV-protective fibers during the spinning process. This method involves incorporating inorganic ceramic micropowders into polymer chips to create a masterbatch. During fiber formation, these particles effectively absorb UV rays in the range of 280–400 nm, significantly reducing their penetration through the fabric.
(2) Applying functional finishing techniques, where UV-blocking agents are applied to the fabric and bonded firmly to the textile surface. This method is often used on existing fabrics to enhance their UV protection properties without altering the base material.
Today, UV-resistant textiles are widely available in various forms, including outdoor sportswear, UV-protective shirts, umbrellas, curtains, and tents. As awareness of UV risks continues to grow, demand for such products is expected to increase, driving further innovation in textile technology.
With ongoing research and development, the future of UV protection in fabrics looks promising, offering better comfort, durability, and effectiveness for consumers around the world.
