Rit DyeMore Synthetic Fiber Dye now makes it possible to dye synthetic fabric and fabric blends, which include anything with 35% or more polyester, acrylic, acetate or nylon. 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. Looking to create something unique? Rit has been tie-dyeing clothing for decades. It's also the perfect tool to create an ombré, dip dyed or shibori pattern. It can even dye 3D printed items, lacrosse sticks, wigs, faux fur and some plastics. Whether you are dyeing a garment in a color you love (but wasn't available to buy), creating a costume or decorating for a party, all you need is a stainless-steel pot to get started. With 250+ color recipes available on the Rit's website, it is almost certain you'll find the right color for your needs. Please note: Due to the complexity of dyeing synthetic fabrics, you must use this dye in a stainless-steel pot on your stove top to maintain a high-water temperature throughout the duration of dyeing. Cannot be used in a washing machine.
