These dyes are specifically for dyeing cellulose fibres, such as cotton, linen, bamboo, tencel and rayon.
They are fibre reactive and form a covalent bond with the fibres they are applied to, and are light and wash fast.
They are cold setting dyes and do not require heat to set them, but they do need an alkaline medium (Soda Ash) to set.
To use them, dissolve the dye in warm water, then apply to the fibre or fabric that has been soaked in a solution of soda ash and warm water.
Cover the dyed goods in plastic and leave for 24 hours to set, before rinsing well.
Each 20gms of Cotton Reactive Dye will dye approximately 500gms of cotton fibre/fabric or yarn.
