|Black velvet fabric printed with discharge paste & illuminating acid dye|
A concentrated stock solution of dye (made using boiling water and vinegar) is combined with a discharge paste. The paste is applied to the ready dyed fabric with a brush or stamp. When dry, the discharge paste is activated by pressing the fabric with a hot iron on a steam setting.
The final stage is to set the replacement dye colour using the traditional method of steam fixing, before rinsing away the surplus dye and chemicals. You can find out more about how to steam set dyes from our Fact File page.
