Himalayan Rhubarb Raw Material

Himalayan Rhubarb Rheum emodi is a natural dye obtained from the roots of a mountain rhubarb variety that grows in the Himalayas. It gives deep golden tones varying from yellows to yellow-reds. Use at 10-20% WOF on mordanted yarns and cloth. Simmer mordanted fibres gently for 1 hour. 

Mordanting: use alum mordant at 15% WOF for protein fibres. For cellulose mordant with tannin at 8% WOF and then alum at 15%, or alum acetate at 8%.
