Now a days a lot of pollution caused by the textile mills that use synthetic textile dyes that harm the environment. To reduce the use of synthetic dyes, natural dyes potential for use. One of the natural resources that have the potential for natural textile dyes are plant mango (Magnifera indica L). Part of the mango crop that can be used as dyes are leaves. On mango leaves are pigment-containing mangiferine kromofos carbonyl group. This pigment is easy release of these substances on the fabric because it is a kind of gum mangiferine that can be used as a coloring agent. Abundant mango crop in Indonesia, and the price is cheap. This experiment aimed to obtain the dye from the leaves of mango and its utilization in textiles. Natural dyes extracted tested on cotton and silk fabric. Natural dyes obtained by boiling the leaves of mango extraction with distilled water in 1:4 ratio. Fabric to be colored must dimordanting then soaking the natural dyes with time variation 10, 20, and 30 minutes later fixation. Fixer solution used is Al2(SO4)3, FeSO4. and CaCO3. Fabrics that have been fixed then r'ashcd and analyzed with the washing water. Wavelength of the data obtained colour fadeing values based long time of fabric dyeing and fixer solution. In the results. the textile silk tie by both the dyeing time 30 minutes and fixer solution Al2(SO4)3 for 4999. For cotton textiles showed the most excellent colour fadeing dye at 30 minutes at fixer solution Al2(SO4)3 and CaCO3 at 4265.67
