Jacquard Idye Poly
iDye Poly is virtually the only dye that will color polyester. In fact, it will color almost anything synthetic, including plastics and nylons, buttons, frisbee discs, 3D printed objects, toys, dolls, wigs, cleats, urethane coatings and more. The dye comes in a dissolvable packet, so there are never any messy powders to handle: simply drop the packet in a pot of water, add the fabric or objects and bring to a simmer.
