Abstract :
Ultraviolet radiation (UVR) from Sunlight damages the skin in the form of sunburns and skin cancer, depending on the exposure time. Sunscreen products application and proper clothing are highly recommended for skin protection from UVR. This study investigated the level of UV protection factor of dyed wool fabrics dyed with different dyes (acid, chromium and metal complex dyes). The results revealed that UV protection factor (UPF) of wool fabrics has increased just a little after dyeing. The UPF is increased from 2.7 to 4.4 for undyed and metal complex dyed samples, respectively.The other dyed samples have got the UPF as much as Benzophenone, a UV absorber. The amount of UPF displayed that the dyed wool fabrics have got weak UV-protection, and the dyeing has not any significant effect on UV-protection of wool fabric.
