UV protective textile clothing for workers exposed to natural and artificial UV radiation

摘要

Some amounts of ultraviolet radiation are beneficial for humans but excessive exposure can cause many negative health effects to the skin and eyes and also can affect the immune system. Exposed area of skin should be covered by working clothes with low UVR transmission. It concerns both exposure to natural UV or prolonged exposure to artificial UV. This article presents some aspects of UV protective textile clothing for workers exposed to natural and artificial UV radiation. This article presents results of selected textile samples transmittances and calculated UPF and new proposed AUPF, which describes protective properties against UV of textiles. The UPF and AUPF differs substantially between each other, what is related both to the weighting factors of erythema and actinic efficiency functions and spectral range of these functions. UV protection by clothing depends on a large variety of factors, such as type of fiber, color or moisture content. Contrary to popular opinion, however, some fabrics provide insufficient ultraviolet (UV) protection.
