Abstract

Now a day, there are many synthetic dyes use in many industries such as textile, food, and madicines. The synthetic dyes can give bad effect to the human health and enviroment. Because of that the synthetic dyes will be replaced by the natural dyes. The research is about utilization of natural dyes from root bark extract of Morinda citrifolia.. The natural dyes from root bark is extracted with maseration (methanol) and extraction (aquades). The extraction of root bark morinda was done by using water and methanol as solvent with ratio of 1:20 (w/v) (10 g sample : 200 mL solvent). The extract obtained from water was blackish brown, while from methanol solvent was reddish brown. The extract obtained was used to dye cotton fabric with addition of 1.00 g whiting as a mordant. In the process of soaking the cotton fabrics, there are some variation of immersion that 16, 24, 28, 32, and 36 hours. From the variation of immersion, the best immersion is 32 hour. Extracts of both solvents can dye cotton fabrics with varied colors : yellow and red. Mordant can strengthen the bond between the fiber and dyes and sharpen the fabric color. Endurance test by using 0.5% detergent water to soak for 15 minutes, showing the colour of fabric without mordant easily fade, whereas the colour with mordant of whiting do not easily fade.
