Mother MacKenzie’s Miracle Dye Mix is a combination of super-milling and weak acid dyes. Weak acid dyes bond with fiber through the application of heat, acid, and capillary action. Super-milling means that the dye is colorfast when washed with hot water, soap, and agitation. This means that even if you felt it or full it, the color won’t decrease and it won’t change hue. It won’t change during dry cleaning either.
These dyes only dye protein; so you can dye wool, silk, camel, dog hair, rabbit, alpaca, etc. You can also dye some rayon and all nylons (which think they are wool). You can also dye casein plastic (a milk by-product), bone, shell, human hair, and pearls. They dye vegetable proteins such as soy silk but they do not dye cellulose fiber like cotton and linen. They do not dye synthetics like polyesters and acrylic.
This Dye Mix kit contains approximately 15 grams of each color and is enough dye for sixty pounds of wool.
