Product Description
Natural Indigo Dye is an extract prepared from Indigofera tinctoria which is cultivated for this purpose. Indigo is the legendary source of colourfast blues and its ability to produce a wide range of shades has made it the most successful dye plant ever known. Indigo grows all over the world but flourishes best in hot, sunny, humid areas. Indigo can give clear blues that range from the tint of a pale sky to a deep navy that is almost black. Our indigo comes from a farm in south India and is very strong (approx 50% indigotin). It reduces beautifully in an indigo vat.
The dye is converted into leuco form with caustic soda and sodium hydrosulphite in soft water. The dyeing is
carried out in the reduced exposed to air. By oxidation the dye slowly changes into blue on the fabric.
The dyed material has good fastness to light and wash.
Rubbing fastness is reasonably good. The illustration of the plant is enclosed.
Obtained from the leaves of Indigofera tinctoria plant. The leaves are fermented in fermentation pits. The dye is precipitated by oxidation or by passing the air. The precipitated dye settles down at the bottom. The cake is dried in the air and sun.
