Rit DyeMore for Synthetics

If you cannot find that perfect coloured fabric to match your quilting, patchwork, sewing or home decor project then why not custom dye your own fabrics. These fabric dyes can add depth and texture in exactly the colour and tone you want.

Rit started their lives shortly before World War 1. Charles C Huffman began experimenting with fabric dyes for use in the home, starting with mega equipment and a vacant store in Chicago. Huffman had a new product ready for market in 1917 which was a dye with soap that would dye and wash at the same time. The product was named Rit in honour of a friend, Louis L Rittenhouse, who had helped financially and became the first Vice President.

Rit's Slogan became: "Never Say 'Dye' .... Say Rit!"

With so many diverse synthetic fabric dyes on the market, Rit introduce Rit DyeMore, a dye specially made for synthetic fabrics like polyester, polyester cotton blends, acrylic, and acetate. And like our All-Purpose formula, DyeMore is non-toxic and perfect for use in the home.  

No matter what you plan to dye, whether it’s a pair of jeans or set of curtains, the first step is to choose the right dye for your fabric or material. Always check the care label for the fiber content of the item you plan to dye.

This dye is for synthetic fibers, which include polyester, acrylic, acetate and nylon. If you have a blended garment that contains more than 35% synthetic fibers, this is the dye you will need to use. If you are dyeing a garment with less than 35% synthetic fibers, use Rit All-Purpose Dye instead.

Stainless Steel Pot

Measuring Cup

Metal Tongs

Plastic Gloves

Dishwashing Liquid

Plastic Table Cover


  1. To determine how much dye is needed, weigh the item to be dyed on a food scale or estimate the weight. As a general guideline, one bottle of Rit DyeMore will dye up to two pounds of dry fabric. If dyeing 100% polyester or trying to achieve a very bold color, double the dye quantity.
  2. Fiber content and weight effect how color appears. If you are in doubt as to whether your fabric will accept dye or achieve the color you want, we recommend testing a swatch first.
  3. Before dyeing, remove any visibile stains on the garment. This will help achieve uniform color results when dyeing. Pre-wash item in warm, soapy water. This helps to remove any finishes that may interfere with dye absorption.
  4. Cover work area around stove with plastic table cover or newspaper and have paper towels handy to protect against any possible spills.
  5. Wear rubber gloves to protect hands from getting stained and to insulate them when working with hot water.
  6. Due to the complexity of dyeing synthetics, you must use the stovetop method to maintain an almost boiling temperature for the duration of your dyeing (around 180 F°).
  7. Fill a stainless steel pot with enough water for the fabric to move freely. We recommend using three gallons of water for every pound of fabric.
  8. Add 1 teaspoon of dish detergent to help promote level dyeing.
  9. Cover pot and heat water on stove top to just below boiling (or 210 F°).
  10. When water begins to simmer, add well-shaken dye and mix well.
  11. Wet the item you are going to be dyeing and add it to the dyebath.
  12. Keep temperature at a low simmer for the duration of your dyeing.
  13. Stir slowly and continuously. The first 10 minutes are the most critical. Stirring helps to ensure an even color with no splotches.
  14. Item can remain in dyebath from 10 minutes up to one hour. If dyeing polyester or a polyester cotton blend, keep the fabric in the dyebath for at least 30 minutes to ensure that the color takes fully. Nylon tends to dye very quickly and much darker than other fibers so the actual time needed in the dyebath is less.
  15. When desired color is achieved, remove from dyebath. Fabric will look darker when wet and will dry lighter. Squeeze out excess dye.
  16. Rinse in warm water and then gradually cool water until rinse water begins to run clear.
  17. Wash in warm water with a mild detergent, rinse and dry.
