Wearable Sunscreen

Written by:

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 sun 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 differ substantially between each other, what are related both to the weighting factors of erythema and Actinic efficiency functions and spectral range of these functions.

In the last two decades, the media and the scientific community have highlighted the depletion of the ozone layer and the resulting elevation in the levels of ultra-violet radiation (UVR) reaching the earth's surface. In the recent years, consumers have become increasingly aware of the need for sun protection, which is related to the incidence of sun induced skin damage and its relationship to increased exposures to UV light.
