colouring agents

Rubia colouring agents are made ‘by nature’. Contrary to synthetic colours, at which the colour is only determined by one molecule, the natural colour of Rubia is determined by even 15 different substances. This gives an authentic, rich and natural colour to the eventual dyed end product which can hardly be equalled by chemical colouring agents.

Because of the use of various plants, each one of them is strong in its own colour applications and Rubia can make almost the entire colour spectrum with these colours. ‘Rubia Red 100% natural dye extract’ is recommended by the Global Organic Textile Standard (GOTS).

Rubia Natural Colours produces 100% natural colour agents with unique characteristics:

• vegetable colouring agent in powder form;
• the extract contains a great diversity of colouring components. Those colouring components cause a special colour glow which cannot be equalled with synthetic colouring agents;
• perfect attachment to fabrics, threads and other products such as wool and leather;
• environment-friendly production process and fully renewable materials. Cultivation does not compete with food crops because this plant can ideally be varied with a monoculture which would otherwise make things hard for the growers;
• cultivation and production in the Netherlands. Quick transport and low use of energy and raw materials; 
• good light fastness and very good washable;
• homogeneous, consistent, high quality because of the registered cultivation of a pure crop. Track tracé fully known and documented.
