Product Descriptions:
Sappan pink also called Sappan wood natural dye extract is produced by solvent extraction method. Sappan wood is also called Indian redwood or the heartwood of Caesalpinia trees.
The heartwood contains different flavonoids that are water soluble, including brazilin, protosappanin, and haematoxylin. Brazilin is the main flavonoid found in the heartwood, which is well known as a natural color dye used to stain cotton, silk, and wool. Brazilin grows best in hilly regions. Brazilin gives fabric its red color. Brazilianin is extracted by first crushing the wood into powder form, and then boiling the powdered bark with water at high temperatures for about 40-45 minutes. Afterward, it is filtered and bleached with different mordents to produce a range of strong red dyes ranging from deep crimsons to pinks.

Dyeing Process:
(A) Wet the fabric with wetting agent/soapnut(Reetha) or normal wash with water at 50 degree for 20 mins.
(B) Pre Mordant :- Pre-treat the material with alum 12% of fabric weight at 85°C for 60 mins.
(C) Dyeing :- Add the required amount of dye to the dye bath. PH of dye bath needs to be maintained at pH 5. If it is higher than pH, 5 add vinegar, if below pH 5, use lime or soda ash. Stir well to dissolve the dye. Add fabric to the dye bath and maintain at 95°C for 60-80 mins. We check all our natural dyes at 5% of fabric weight; you can amend the percentage as per lighter or darker shade required.
(D) Post Treatment :- Conduct soaping of the dyed material with non-ionic detergent (0.5gpl) or ezee soap at 50°C for 35 mins.
(E) Then conduct cold wash of the material at 50°C for 20 mins or more time.
(D) Hot wash and then cold wash the material.
(D) Then cold wash the material.
