Acacia Catechu (Cutch) Dye

Cutch dye is a natural extract made by heating the wood of the Acacia catechu tree and concentrating the tannin-rich solution. The resulting dye is high in natural tannins, which means it can bind well to fibres and, in some cases, even dye without a mordant.

This makes cutch an excellent choice for beginners and experienced dyers alike. It works particularly well on natural fibres such as cotton, linen, wool, and silk, producing soft, even shades with depth and character.

Cutch is prized for its range of warm, earthy hues. Depending on the dyeing process, fibre type, and use of modifiers, you can achieve:

• Light beige and honey tones
• Warm caramel shades
• Rich medium browns
• Deep, dark chocolate hues

Adding iron can shift the colour towards darker browns, while different mordants can subtly influence the final result. Like all plant dyes, cutch offers an element of variation, making each dye batch unique. We hope you enjoy the experimentation that natural dyeing involves!

Using cutch dye is relatively straightforward. The dye is typically dissolved in hot water to create a dye bath. Fibres should be clean and, if desired, mordanted before dyeing.

One of the advantages of cutch is its high tannin content, which helps it bond well with fibres. For fibres like cotton, this can reduce the need for additional tannins in the preparation process.

The fabric is then simmered in the dye bath until the desired depth of colour is achieved. Longer dye times and repeated dips can deepen the shade.

Cutch dye is known for its excellent colourfastness compared to many other natural dyes. Thanks to its high tannin levels, it forms a strong bond with fibres, resulting in colours that hold up well to washing and everyday use.

While no natural dye is completely immune to fading, cutch is considered one of the more durable options. With proper care—gentle washing and avoiding prolonged direct sunlight—its rich tones can last for years.

Cutch dye is derived from a plant source and when compared to synthetic dyes, has a much lower environmental impact. The dyeing process uses fewer harsh chemicals.

Acacia catechu (cutch) plant dye stands out for its reliability, rich colour palette, and ease of use. Whether you’re creating naturally dyed fabrics at home or developing sustainable textile collections, cutch offers consistent, beautiful results.

Its earthy tones, strong performance, and natural origins make it an essential addition to any plant dyeing practice—combining tradition, sustainability, and creative expression in each batch.

• Wear protective gear - gloves, an apron or old clothing, a dusk mask when handling powders. 
• Dedicated equipment - keep tools separate from your kitchen items. Use stainless steel or enamel to prevent reactions or colour modification.
• Ensure the space you’re working is well ventilated.
• Handle mordants and plant dyes with care.
• Dye baths involve hot water, be mindful of burns or spills.
• Dispose of materials responsibly.
