Brown Catechu Natural Dye Extract is an extract of acacia trees used as a tannin, and as a dye. The catechu extract is high in natural vegetable tannins, Cutch is an important historical brown dye that comes from the heartwood of the cutch tree (Acacia catechu). It is a very easy dye to use and it is both light-fast and wash-fast. Cutch is an excellent dye for cottons as it is high in tannins, and it is also suitable for dyeing wool, silk, and cotton a reddish-brown. Cutch gives grey-browns with an iron mordant and olive-browns with a copper mordant. Alum will give brighter tones.
As a mordant, 10% is enough
Use 20-30% WOF to dye a medium depth of shade on cotton.
To use mainly the catechu-tannic acid, use cold water. To yield the browns from the dye component catechin, you need hot (boiling) water to dissolve.
Dye baths can be re-used for lighter shades.
Dyeing with cotton; cotton fabric is premordanted with natural mordants pomegranate or myrobolan. Disolve Cutch powder in a little hot water to make a paste and then dissove in dye bath. Heat for 90 min at 80° to 90°C with material – to- liquor ratio 1:20.
