Dyeing Process
Ready-for-dye cotton yarn is washed with non-toxic biodegradable detergent and then mordanted with alum and tannin (myrobalan extract).
The mordanted yarn is then rinsed and treated with an inorganic, non-toxic, leveling agent and then immersed in a hot dye bath containing dye extract (lac).
The dyed yarn is rinsed and thereafter washed in hot detergent, rinsed with water and then dried.
