The red heartwood of Red sander is used for dyeing and produces a range of brown shades. It can be used to dye silk, cotton and wood. By adding mordents, we can alter the shades. Alum and tin are used as pre-mordents and ammonia after baths provide different shades of colors.

Dyeing Processes

Pre mordant: Pre-treat the material with alum 10% of fabric weight.
Dyeing: To get satisfying colors, use Red sander at 30% of fabric weight. pH of dye bath needs to be maintained at pH 5(vinegar, lime and sodium hydroxide are used to adjust the pH). Dissolve Red sander in water and simmer with fiber until all the color has been taken up.
Post treatment: Conduct soaping of the dyed material with non-ionic detergent (0.5gpl) for 20-30 mins.
Hot wash and then cold wash.
