Nano Ultraviolet Finishing of Textiles Using Inorganic UV- Blockers–The Sustainable Approach of Producing Protective Clothing for Better Tomorrow
Abstract: The diminution of the ozone stratum,due to global warming, is likely to intensify existing health effects caused by exposure to ultraviolet (UV) radiations, as stratospheric ozone is a predominantly effective UV radiation absorber. As the ozone layer becomes thinner, the protective filter provided by the atmosphere is gradually abridged. Subsequently, human beings and the environment are exposed to higher UV radiation levels, particularly higher UV-B levels, which have the greatest …
