This research studied the optimized dyeing conditions for natural indigo dye (Indigofera tinctoria) on silk yarn. Vatting of natural indigo dye was investigated under different temperatures and times and the natural dyeing auxiliaries were used i.e. tamarind and ash solutions. The results informed the optimum vatting condition for the indigo dye at 90°C for 30 minutes and the optimum pH was 12. The sugars in tamarind solution was expected to work as a reducing agent for dye vatting whereas the ash solution derived from banana barks was used as an alkalinity controller. Dyeing silk yarns with leuco indigo dye under a short time (5 minutes) provided a complete dye distribution with satisfactory color strength on silk and very good fastness properties.

Indigofera Tinctoria

Natural indigo dye, Indigofera tinctoria, was applied on poly (lactic acid) (PLA) fabrics by exhaust dyeing in the presence of 5 g/L sodium dithionite and 0.2 g/L NaOH. Three dyeing parameters e.g. dyeing temperature, dyeing time and dye concentration were studied. When 5%owf indigo dye was applied on PLA, the maximum color strength was obtained at 80°C and 60 minutes. The color strength also increased as the dye concentration increased in the range of 4–20%owf. Applying natural indigo dye to PLA fabrics is more attractive than the commercial one due to better energy savings and the process being environmentally friendly.
