Advances in UV Protective clothing

Light is prime energy source & essential element for life. Sunlight spectrum ranges : Complete Sunlight - from about 290 nm to 3000 nm. UV spectrum in sunlight - from 290nm to 400 nm. Human body generates vitamin D when it is exposed to small doses of UV radiation. But overdose of UV radiation causes acute , chronic reactions and erythematic damages (skin reddening) or other diseases such as skin cancer. Because of growing consumption of conventional fuels in last few decades there has been a steady decrease in the stratospheric ozone. Ozone is a very effective UV absorber. So, it’s decrease has led to the increased UV radiation reaching the earth’s surface and has thus enlarged the risks of the negative effects of sunlight. Recognizing these facts, it is clearly very important to protect skin from excessive amounts of UV-radiation.
