- Abstract
Ultraviolet (UV) radiations are carcinogenic, repeated UV exposure causes damage to skin cells and leads to develop skin cancer. Generally, commercially available clothing items provide a limited UPF (less than 15). Present research has been taken up to develop eco-friendly Khadi fabric having UV protective action along with good colorfastness properties by extracting the dyes using galls of at Q. infectoria various dyeing concentrations. Optimal results were achieved by dyeing at 90-100 °C for 90 minutes using the pre-mordanting method with different mordants i.e. Punica granatum, Phyllanthus emblica, Terminalia bellirica, Acacia catechu and Ferrous sulfate.The developed fabric samples were evaluated for ultraviolet radiation in terms of UPF and the colour fastness towards washing, rubbing, and sunlight and colour strength (K/S) value. The results of colour fastness to washing and rubbing showed good to very good, whereas the colour fastness to light showed good to moderate fading. It showed very good colour strength (K/S) and provided beautiful shades in dyed samples. The data obtained showed that the mordanted samples have high dye uptake with excellent UPF values. These results are very important for industrial application with the production of natural dyes having an excellent UPF value with an inexpensive source from the galls of Q. infectoria on Khadi fabric.
