However, getting a fabric wet can significantly reduce its protection, except in the case of silk and viscose which become more protective when wet. Polyester, which contains a UV-absorbing benzene ring, and fabrics that have UV absorbers added during manufacturing, also offer higher protection levels. UPF (Ultraviolet Protection Factor) is a relatively recent rating system for sun protective textiles and clothing. It measures the ratio of UV that causes sunburn, which is blocked by the fabric. For example, a fabric with a UPF rating of 30 blocks 96.7% of UV, allowing only 1 unit of UV to pass through for every 30 units that fall on the fabric. This is in contrast to the traditional SPF (
