Before dyeing polyester with Rit dye, it is important to note that the fabric should be a blend of at least 60% polyester for the dye to properly bond to the fibers.

Here are the steps:

  1. For best results, pre-wash the fabric to remove any dirt or residue and then submerge it in hot water with a teaspoon of washing detergent.
  2. Mix the Rit dye according to package instructions and then add it to the hot water, stirring well.
  3. Allow the fabric to soak for at least one hour, occasionally stirring, before rinsing and washing as usual.


  • It is also important to note that Rit dye will not work to lighten the color of the polyester fabric – it can only darken or deepen the existing shade.
  • Additionally, Rit dye may not be as vibrant on polyester as on natural fabrics such as cotton or wool.
  • If you want a bold, bright color on polyester fabric, using a fiber-reactive dye made explicitly for synthetic materials is best.
  • But if you want to slightly change the shade or add depth to the color of polyester fabric, Rit dye can do the trick.
  • Experiment with different techniques and strengths of dye solutions to find the perfect hue for your project.


  • Ensure the fabric is clean and free of dirt or oils before dyeing.
  • Use hot water to dissolve the Rit dye in the dye bath, as this will help the color to adhere better to the polyester fabric.
  • Allow the dyed fabric to dry fully before laundering, as the colors may bleed during washing if it is not completely dry.
  • When washing the dyed polyester fabric, use a gentle cycle and cold water to preserve the color.
  • It is also recommended to hand wash or use a gentle cycle and cold water for future washings to preserve the color.
  • Note that Rit dye may not work as well on darker shades of polyester fabric, as the original color may show through.
  • Remember that Rit dye is not permanent on polyester fabrics and may fade over time with washings.

Overall, Rit dye can be used to color polyester fabric, but it may not have as long-lasting results compared to other methods of dying synthetic fabrics.

But for a quick and easy at-home option, Rit dye is a great choice for adding color to polyester fabric.

Just follow the tips and guidelines above for the best results. Thanks for reading!


Is polyester difficult to dye?

It can be difficult to dye polyester because the fabric is non-absorbent. You need to use a special type of dye that attaches to the material’s fibers, and even then, it can be tricky to get good results.

Some people try to dye polyester by using a regular dye and adding vinegar or baking soda to the mix. This may work for some colors, but it’s not likely to produce very consistent results.

If you want to dye your polyester clothing a specific color, it’s best to use a specialized dye designed for this purpose.

Can I soak fabric in Rit dye overnight?

Yes, you can soak fabric in Rit dye overnight. For the best results, make sure to follow the instructions on the Rit dye package.

Also, use enough dye and warm water to cover the fabric completely. Good luck!

Does Rit dye rub off?

There is some debate about this, but most people say that Rit dye does rub off.

The reason for this is that the fabric, like natural dyes, does not absorb the dye but simply coats the fabric. This means that it can easily be rubbed or washed off.

So if you want Rit dye to color a garment, it’s best to do so with caution and avoid wearing it right after you dye it. Or you can use a fixative or another method to set the dye better.
