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 ldttle will dye up to two pounds of dry fabric. If dyeing you are trying to achieve a very bolder color, double the dye ratio.
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 area around stove with plastic table cover 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.
Fill a stainless steel pot with enough water for the fabric to move freely. Cover pot and heat water on stove top to just below boiling (or around 200 F°).
If you are dyeing with Rit All-Purpose Dye: To enhance the color: (1) add one cup of salt when dyeing fabrics containing cotton, rayon, ramie or linen; (2) add one cup of vinegar when dyeing fabrics containing nylon, silk or wool. Add 1 teaspoon of dish detergent to help promote level dyeing.
When water begins to simmer, add 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 dye bath. Fabric will look darker when wet and will dry lighter. Squeeze out excess dye.
