Onion which are red, yellow, shallots, sweet, pearl, green in color are a rich source of lutein. Nowadays, lutein in becoming an increasingly popular active ingredient used in textile coloration. The potential use of onion as a natural textile colorant has not been exploited to it full extent. This is due to the lack of information on its safety, stability and capability in textile coloration. In this study an experiment was conducted to study the use of an extract isolated from onion as a natural dye. Using the onion in 100% cotton fabrics and 100% polyester fabrics under normal dyeing conditions. Studies of the dye concentration and dyeing method and also the mordant were undertaken. The tests which led us to decision were color fastness to wash and rubbing
