| Summary: | Natural colorants play a vital role in the production of eco-leather by substituting environmentally hazardous and toxic synthetic dyestuffs. In this study, a natural dye is extracted and optimized from the bark of Ficus sycomorus, a plant species locally known as shola, by designing different combinations of concentration, temperature, and time parameters. A dye extracted from 120 g/l concentration at a temperature of 1000°C for 60 minutes showed the highest absorbance value, and it has been used for further dyeing processes with and without mordant. Properties such as color strength (k/s), L∗a∗b∗ values, and color fastness of a dyed leather specimen were measured and analyzed. Oxalic acid mordant-dyed leather samples mordanted with the postmordanting method have revealed the highest k/s value among other experimental samples. Moreover, better color fastness properties were obtained from a leather sample mordanted with oxalic acid. Consequently, a dye extracted from the bark of Ficus sycomorus can be used as a leather dyeing material. |
