چکیده مقاله :

Abstract: Sunlight causes to damage skin in the form of sunburns and skin cancer in comparison to exposure time because of including ultraviolet radiation (UVR). It is recommended application of sunscreen products and the use of proper clothing for skin protection from UVR. Therefore in this research the wool fabrics dyed by different dyes (Acid, Chrome and metal complex dyes) and the amount of UV-protection factor of dyed wool fabrics were investigated. The results revealed that the UV protection factor (UPF) of wool fabrics have 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 as well as the dyeing has not influenced significantly on UV-protection of wool fabric. .

چکیده انگلیسی:

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.
