Jacquard iDye Poly is for dyeing polyester and nylon fabrics, and it has never been easier! iDye's self-dissolving packet eliminates the handling of messy powders. Just fill a stainless steel or enamel pot with the recommended amount of water, add an iDye packet and the included Color Intensifier, add a pre-wetted garment, place the pot over high heat, stir until the iDye is dissolved, and continue to stir frequently. Approximately 1/2 to 1 hour. One packet dyes 2 to 3 pounds of fabric. 0.5 oz. Orange.
