uv fabric

As sun protective clothing is usually meant to be worn during warm and humid weather, some UV-blocking textiles and clothing may be designed with ventilated weaves, moisture-wicking and antibacterial properties to assist in cooling and breathability. UPF (Ultraviolet Protection Factor) represents the ratio of sunburn-causing UV without and with the protection of the fabric, similar to SPF (Sun Protection Factor) ratings for sunscreen. While standard summer fabrics have UPF ~6, sun-protective clothing typically has UPF ~30, which means that only 1 out of ~30 units of UV will pass through (~3%).

A relatively new rating designation for sun protective textiles and clothing is UPF (Ultraviolet Protection Factor), which represents the ratio of sunburn-causing UV measured without and with the protection of the fabric. For example, a fabric rated UPF 30 means that, if 30 units of UV fall on the fabric, only 1 unit will pass through to the skin. A UPF 30 fabric that blocks 29 out of 30 units of UV is therefore blocking 96.7%A relatively new rating designation for sun protective textiles and clothing is UPF (Ultraviolet Protection Factor), which represents the ratio of sunburn-causing UV measured without and with the protection of the fabric.
