Dyeing of red sandal wood on wool and nylon

Abstract

The use of red sandalwood (<i>Pterocarpus santalinus</i>) extract as a dye for wool and nylon has been explored. The colouring components were extracted with organic as well as aqueous alkaline solution from the sandalwood and the physico-chemical properties of the dried extracts evaluated. The extracted dye was applied on wool and nylon with and without mordants and the fastness of the dyed samples to light and washing studied. The light fastness of the dyed wool samples improved substantially on mordanting with copper sulphate and ferrous sulphate. The wool and nylon samples dyed and treated with mordants, except copper sulphate, showed good wash fastness
