Coloration of textiles, traditionally achieved using natural dyes, commonly employs synthetic dyes at the industrial level. A revival of commercial interest in natural dyes has opened several research avenues. This paper investigates the application by padding of cotton fabric with 10 g/l of two natural dyes derived from the Acacia plant family. Three mordanting techniques were studied; of which post-mordanting produced the most even shade. Among the two mordants investigated, the use of copper sulfate resulted in a level beige shade at 15 g/l concentration while ferrous sulfate performed best at 5 g/l yielding a yellow-grey shade. An optimum process-sequence for the copper sulfate mordant was "pad (dye)${ ightarrow}$dry${ ightarrow}$steam followed by pad (mordant)${ ightarrow}$steam${ ightarrow}$dry", and for ferrous sulfte it was "pad (dye)${ ightarrow}$steam${ ightarrow}$dry followed by pad (mordant)${ ightarrow}$steam${ ightarrow}$dry". Typically a change in mordant resulted in a different shade with the same dye. The study concluded that padding is a readily adaptable process for the dyeing of cotton using natural dyes and acceptable fastness in shades can be obtained.
