Rit DyeMore Synthetic Fiber Dye now makes it possible to dye synthetic fabric and fabric blends, which include anything with 35% or more of polyester, nylon, acrylic, or acetate. The versatile, easy-to-use and non-toxic liquid dye is perfect for rejuvenating faded clothing and décor, upcycling, hiding laundry accidents and so much more. It's also the perfect tool to create an ombré, dip dyed or shibori pattern. DyeMore will also work on 3D printed items, wigs, faux fur, and most plastics.
