Abstract: In this study, silk fabric is dyed with natural indigo.Dyed silk fabric with natural indigo was cut in the 20x20 cm 2 size.Excluding a fabric, all fabrics were mordanted in the same percentage with alum metal (KAl(SO 4 ) 2 .12H 2 O).Then, silk fabrics for green color dyeing are dyed separately with weld (Reseda luteola), gall oak (Quercus infectoria Olivier) and together weld (Reseda luteola) and gall oak (Quercus infectoria) in different percentage.Antimicrobial functionality of the twenty seven silk fabrics is established.Tests were conducted against the Staphylococcus aureus ATCC 6538.The results of the counting test showed more reduction of survival Staphylococcus aureus in dark-colored fabric.The number of survival microorganism was determined by counting the colonies as colony-forming unit (CFU/ml) and reduction rate of bacteria was calculated.Coloring compounds and their percentages in the natural dyed silk fabrics are detected by HPLC-PDA (high performance liquid chromatography with diode array detection).Colour measurement is done of the dyed silk fabrics by CIEL*a*b* spectrophotometer.
