Dyed Textile-Popular Dyes

Vat dyes: Vat dyes are an ancient class of dyes based on the original natural dye, indigo, which is now produced synthetically. Cotton, wool, as well as other fibers, can be dyed with vat dyes.
Direct dyes: Also known as hot water dyes, direct dyes can be used with hot water and require no binding or exhausting agents. They are convenient but lack in color fastness and wash fastness. They are used on cotton, wool, silk and nylon. The colors of direct dyes are duller than those provided by reactive dyes. They can be found in powder form as well as in the form of a liquid concentrate. They do not require any form of 'fixing'.
Procion dyes: Procion fiber reactive dyes are specially formulated for cellulose fibers like cotton, linen and rayon. They also work well on silk. They are considered 'cold water'" dyes making them great for solar dyeing, tie and dye and batik. As for the auxiliary chemicals, all you need is salt and soda ash. Synthrapol is optional but very helpful for rinsing out excess dye. Procion fiber reactive dyes can also be used on protein fibers but different auxiliaries are needed and the dye bath must be simmered.
