  In this study, eco-friendly natural coloring matter such as pomegranate, curcumin, cutch, red onion peel and a mixture of red onion peel/curcumin (40 g/L, 50%) are used. They are extracted in water at 80°C (red onion at boiling). Cotton, wool, silk and nylon fabrics are dyed using conventional method at pH 4 (except cotton at pH 8), liquor ratio 1:40 and 25 g/L dye concentration for a specific time in presence or absence of FeSO4 using simultaneous mordanting method. Colour strength (K/S) and colorimetric data (L*, a* and b*) are measured at specific λmax. Also, fastness properties (light, washing, rubbing) are determined. Also, ultraviolet protection and antibacterial activity of fabrics against micro-organisms strains of Staphylococcus aureus, Klebsiella Pneumoniae and Candida albicans are measured. Results of the dyed fabrics are highly UV protective and have effective a.. View More»
