Dock Yellow Root – Cut
Source: Rumex spp. (Dock family)
Dock Yellow Root, cut and dried, is a traditional dye source used to create warm yellows and coral-pink tones on protein fibres. Thanks to its anthraquinone content, it offers colour versatility depending on the pH of your bath:
-
In acidic to neutral conditions, expect golden yellows.
-
In alkaline baths, it shifts to peachy or pink hues, particularly on silk.
This root also provides mild tannin action, making it suitable for cellulose.
Main Components:
-
Anthraquinones
-
Mild tannins
-
Oxalates (naturally occurring)
Suggested Quantities (WOF):
-
30–50% for strong shades
-
Simmer gently for 45–60 minutes
-
Soak overnight to increase yield
Uses:
-
Yellow and pink dyeing on wool & silk
