Pre-mordanting technique was used for this study. Cotton, wool and silk fabrics were treated with tamarind seed coat mordant solution using 15% concentrations on weight of fabric (owf) and this treatment was carried out at 95 °C for 45 min, keeping the liquor to material ratio 20:1. The cotton, wool and silk fabrics mordanted with 15% tamarind seed coat mordant concentration were further treated with 0.5% and 1% (owf) copper sulphate (Cu) solution at 85 °for 45 min, keeping the liquor to material ratio as 20:1. Cotton, wool and silk fabrics, only mordanted with tamarind seed coat mordant and in combination with copper sulphate mordants, were squeezed and subjected to dyeing.
