In this paper we report a model study to formulate a solid dyestuff product from aqueous extracts of dried Canadian Goldenrod plant material. The dyestuff containing product was precipitated as insoluble metal complex from the aqueous dyestuff solution [18,19]. Basic analytical parameters of the solid plant dye e.g. content of total phenolics, metal content have been analysed.
Dyeing behaviour and colour strength have been tested in dyeing experiments and results were compared to dyeings obtained with direct use of aqueous plant material extracts.
