Rit Midnight Navy DyeMore Dye for Synthetics

Inspired by the depth and elegance of a moonlit sea, Midnight Navy is a deep, classic blue designed specifically for synthetic fabrics. Whether you’re rejuvenating faded polyester apparel, upcycling accessories, or customizing synthetics like plastic, wigs, or 3D-printed pieces, this versatile liquid dye delivers rich, long-lasting colour. It works best with 35%+ synthetic blends (polyester, acrylic, acetate, nylon) and requires stovetop dyeing to maintain the high water temperature needed for vibrant results.
