Jacquard ‘Bulk iDye Poly’ is the cost effective solution for dyeing larger quantities of polyester and nylon fabric. It will also dye almost any synthetic material, including some plastics and acrylics, buttons, golf balls, 3D printed objects, toys, dolls, wigs, urethane coatings, as well as many types of theatrical props and costumes! Each 450g pot is resealable and contains sufficient dye for up to 43kg/96lb of dry weight material (equivalent to 32 packs of 14g iDye Poly). Bulk iDye Poly comes in 16 vibrant colours, and ‘Colour Intensifier’ is also available for dyeing deeper colours on polyester!
Suitable Fabrics: 100% polyester & nylon use.

Which iDye?
• for 100% polyester and nylon use iDye Poly
• for polyester blends use iDye and the corresponding color of iDye Poly
• for 100% natural fabrics use iDye


Dye Amounts
Use 3-5% dye by dry weight of fabric for optimal depth of shade. Use less dye for lighter shades.

Not all synthetic fibers are created equal. Results will vary depending on type of fabric.

Polyester is hard to dye and requires very high water temperature to achieve good color; therefore, we recommend dyeing polyester only with the stovetop method.

Please Note
Instructions below are for achieving the most vibrant color. For lighter shades, use less dye. Add dye to the dye bath in the appropriate amount to achieve desired shade.

Keep in mind that color will deepen the longer the fabric is in the dye bath.

For Best Results
• Read entire instructions before beginning.
• Use the stove top method for iDye Poly and polyester blends.
• Use constant agitation for uniform color.

Stove top method for 100% polyester and nylon
1. Fill a stainless steel or enamel pot with just enough water for the fabric to move freely. Turn heat on high.
2. Add the iDye Poly dye and iDye Color Intensifier (14 ml/2 lbs fabric) to water and bring to a simmer. Stir until dissolved.
3. Add pre-wetted fabric and bring to a rolling boil. Maintain temperature and stir frequently for ½ to 1 hour. For uniform color, use constant agitation.
4. Gradually cool the fabric. Wash with a mild detergent in cool water and dry.

Using iDye & iDye Poly with fabric blends
When computing the percentage of iDye & iDye Poly (to achieve the 3-5% dye used), remember to take into account the blend of your fabric. Not all fabrics are blended 50/50.

Example: To dye one pound of 75% polyester & 25% cotton fabric, you would need approximately ½ oz. of dye. The ratio of iDye for Natural Fibers (cotton) would be 25% or 1/8 oz of dye. The ratio of iDye Poly (polyester) would be 75% or 3/8 oz of dye.

Stove top method for polyester and nylon blends with natural fibers
1. Fill a stainless steel or enamel pot with just enough water for the fabric to move freely. Turn heat on high.
2. Choose iDye Poly color closest to the iDye for natural fabrics color and add both to water. Add iDye Color Intensifier (14 ml/lb fabric) and bring to a simmer. Stir until dissolved.
3. Add pre-wetted fabric and bring to a rolling boil.
4. Add 1 cup/237 ml of non-iodized salt for cotton, linen and rayon or ¹/³ cup/78 ml of white vinegar for silk. Avoid pouring directly onto fabric.
5. Maintain a rolling boil and stir frequently for ½ to 1 hour. For uniform color, use constant agitation.
7. Gradually cool the fabric and rinse until nearly clear. For post treatment during final rinse, fill rinse container with water and add 2 tablespoons iDye Fixative per pound of fabric. Agitate for 2 to 3 minutes. Wash with a mild detergent in cool water and dry.
