Coreopsis Extract
Source: Coreopsis tinctoria (Dyer's Coreopsis)
Coreopsis extract is a high-quality, water-soluble natural dye obtained from the flowers of Coreopsis tinctoria, also known as Dyer’s Coreopsis. It produces vibrant shades ranging from sunny yellow to burnt orange and rust to brown, depending on concentration and modifiers.
Extracted in a process designed for textile use, this dye is ideal for natural dyeing, textile printing, painting and ink making. It is suitable for both protein and cellulose fibres.
Main Components:
• Flavonoids
• Chalcones
• Carotenoid-like compounds
Suggested Quantities (WOF – Weight of Fabric):
• Light Shades: Use 2–4% WOF for pale yellow
• Medium Shades: Use 5–8% WOF for gold and orange
• Darker Tones: Use 8–10% and up WOF or apply modifiers (e.g. iron)
Uses:
• Natural Dyeing of Protein & Cellulose Fibres: Bright and cheerful yellows, soft oranges, and warm rusts depending on WOF and afterbaths.
• Ink & Paint Making: Suitable for water-based pigment binders, gouache, or lake pigment preparation.
• Textile Printing & Surface Design: Use with pigment binder systems or thickened pastes.
The Plant:
Coreopsis (C. tinctoria) is a hardy flowering plant native to North America and cultivated for its rich dye properties. The flowers are harvested and processed into a soluble dye extract through a water-based method designed specifically for textile applications.
Note:
This is a soluble dye extract, not a pigment. It dissolves in water and is ideal for immersion dyeing and printing alike.
