【 摘 要 】

Since hundreds year ago, the application of natural dyes on batik is unique procedure to obtain special fabrics and colour. Today, this technique is gaining popularity all over the world, because of the increased awareness on environmental, ecological aspects, and pollution control. In this research, extraction of dyes from wood of Morinda citrifolia using simple precipitation assisted brine solution has been investigated. The color components extracted and isolated from Morinda citrifolia plant were characterized by Thin Layer Chromatography (TLC), IR techniques and reflectance methods. The natural dye extract obtained from the Morinda citrifolia was used for the dyeing of cotton fabrics. The results indicated that the extracted dye increase significant improvement in fabrics colour. The treated fabrics showed excellent antibacterial activity Gram-positive bacteria Staphylococcus aureus (S. aureus).
