Jacquard iDye Poly Dye
$18.00
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, Worbla & Thibra, 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.
For blended fabrics that contain both synthetic and natural fibers, use iDye for Natural Fabrics with the corresponding iDye Poly color AT THE SAME TIME! Or try pairing two different colors for interesting, two-tone heather effects. iDye Poly may also be used for sublimation transfer techniques and to dye the polyester threads that are used to sew many commercially manufactured garments.
A single iDye packet will dye 2-3lbs/ 1-1.3kg of dry fabric
