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.
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.
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.
Cover work area around stove with plastic table cover or newspaper and have paper towels handy to protect against any possible spills.
Wear rubber gloves to protect hands from getting stained and to insulate them when working with hot water.
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°).
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.
Add 1 teaspoon of dish detergent to help promote level dyeing.
Cover pot and heat water on stove top to just below boiling (or 210 F°).
When water begins to simmer, add well-shaken dye and mix well.
Wet the item you are going to be dyeing and add it to the dyebath.
Keep temperature at a low simmer for the duration of your dyeing.
Stir slowly and continuously. The first 10 minutes are the most critical. Stirring helps to ensure an even color with no splotches.
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.
When desired color is achieved, remove from dyebath. Fabric will look darker when wet and will dry lighter. Squeeze out excess dye.
Rinse in warm water and then gradually cool water until rinse water begins to run clear.
Wash in warm water with a mild detergent, rinse and dry.
