Description
Marigold - This dyestuff consists of dried and ground flower heads of the Tagetes species. It yields rich vibrant yellows, green-yellows and oranges with 20 -30% dried marigold to wof. Marigold is cultivated all over the world for its decorative flowers, for religious festivals and for its colourant. Marigold has a moderate light and washfastness. All measures in dyeing are based on the weight of material to be dyed. This is known as the Weight Of Fibre (WOF). WOF gives a convenient way to state how much dyestuff is needed for a given shade, regardless of whether the dyer wants to colour a few yarns or several metres of fabric. The weight of dyestuff is expressed asa percentage of WOF. For example, to dye a medium-red with madder, we would use 50% WOF. Hence, if we had a pound of cotton (450 g) we would need a half-pound (225 g) of madder.^
