Examining the Effect of Natural and Synthetic UV Absorbers on the UV Protective Properties of Cotton
The demand for healthy lifestyles drives many researches to discover newer technique to impart functional properties in textiles. In the present work an attempt has been made to provide UV resist properties to protect the human skin from harmful effect of UV radiation. To impart UV resist properties to cotton fabric UV absorbers such as natural Aloe Vera finish and synthetic product Rayosan in different concentration on UPF were studied, Aloe Vera and synthetic UV absorber gave excellent protection from UV rays.
In the present time, increase of harmful pollutants in the environment make our living conditions worse, and can produce non-reversible damage on our health and jeopardize the quality of our life. Ultra violet radiation is that electromagnetic radiation emitted by sun which b invisible having high energy and is capable of causing harm to living organism.
UVR is divided into 3 categories based on the wavelength. UV C radiation is almost completely absorbed by the ozone layer and does not affect the skin. UV B radiation affects the outer layer of skin, the epidermis, and is the primary agent responsible for sunburns.
