Natural dye was extracted from Albizia procera sawdust by an aqueous extraction process. The extracted dye wasapplied to cotton fabric, and the dyeing techniques were evaluated. The metallic mordants FeSO4 and CuSO4 were used asdye fixing agents in this dyeing process. Different parameters, such as dye concentration, dyeing temperature, dyeing time,type of mordant, mordant concentration, and dyeing method, were evaluated. It was observed that the dye exhaustion oncotton fabric significantly increased with FeSO4 mordant over that with CuSO4. The shades of the dyed fabric were found tobe dark olive when the FeSO4 mordant was used and brown when the CuSO4 mordant was used. Pre-, meta-, and postmordantingdyeing methods were used to dye the fabric, but the meta-mordanting method was the most suitable for dyeingfabric with sawdust extract. Fourier transform infrared (FTIR) spectroscopy was performed on the extracted dyes and thedyed cotton fabric. The color fastness and tensile properties of all the dyed fabrics were evaluated and compared. The fabrictreated with FeSO4 as a mordant showed better color fastness and color strength (K/S) than the fabric treated with CuSO4mordant. However, the fabric treated with CuSO4 showed better tensile properties than the FeSO4 treated fabric and theundyed fabric.
