Ultraviolet rays are electromagnetic radiation, and the international commission on illumination (CIE) divides ultraviolet rays in solar radiation into 3 wavelength bands: (a) long-wavelength ultraviolet UV-A (wavelength is 315-400 nm), wherein the UV-A accounts for 90% of the total amount of the ultraviolet reaching the ground; (b) medium-wavelength ultraviolet UV-B (wavelength 290-315 nm), which is a source of sunburn of the skin; (c) short wavelength ultraviolet UV-C (wavelength 180-290 nm), ultraviolet can be absorbed by the ozone layer, can not reach the ground. In order to prevent ultraviolet rays from damaging human skin, people have begun to consider the ultraviolet resistance of fabrics and garments.
