Rit works best on many natural, washable fabrics such as ... * 100% cotton, linen, silk, wool, ramie
* Synthetics such as rayon, nylon and acetate
* Fiber blends with at least 60% cotton or other dyeable fiber (Blends will tint evenly but will not achieve full color)
... but there are fabrics that will not accept dye such as ... * Fabrics with 50% or more polyester content
* 100% acrylic, fiberglass, or metallic fibers

* Fabrics with special finishes such as water repellents
* Fabrics with bleach damage or extensive staining
* Fabrics washable only in cold water or labeled "dry clean only" If you are in doubt as to whether your fabric will accept dye, test a swatch.
