ANTIBACTERIAL AND FASTNESS PROPERTIES OF SALVIA OFFICINALIS (L) OF SILK DYED FABRIC

This present study investigates the extraction of dye pigment from Salvia officinalis (L) leaves to dye silk fabric. The aqueous dye extraction method and dyeing was employed by using a standard process and carried out under varying conditions such as pH, duration, temperature and concentration of dye material. In each case the optical density or absorbance value has been estimated using colorimeter. The dyeing behaviour of natural dye extracted from the leaves of Salvia officinalis (L) on silk fabric has been investigated the effect of different methods of application of selected mordants like Alum and Myrobolan. Colour values and colour co-ordinates were evaluated. The dyed silk fabrics showed acceptable fastness properties and antibacterial activity against Gram-positive and Gram negative bacteria.
