Message: Can I use Procion MX or acid dyes on acrylic yarn?

Acrylic yarn cannot be dyed with fiber reactive or acid dyes. Both types of dye will wash out of acrylic yarn. You must use either disperse dyes (for pale to medium shades) or another class of dyes, known as basic dyes. Both need to be "cooked" into the fiber, raising the temperature slowly and carefully between 60 and 70°C (140 and 158°F). See the following pages for more information:

Dyeing Acrylic with Basic Dye

and

Dyeing Polyester with Disperse Dyes

Disperse dyes can be used on most synthetic fibers, not only polyester.
