Obtaining successful results is easy with RIT ProLine dyes. Our dyes are tested for purity, concentration, strength, and color throughout the manufacturing process to ensure that you are getting consistent and high quality color. And, our dyes conform to ASTM D-4236, so they are safe for arts and crafts applications.
We provide dyeing instructions below, but if you have any questions, please contact us at 1-866-794-0800.
Tips for Dyeing in Bulk:
- Begin by weighing the material you want to dye. Weigh the material when it is dry, and if you are dyeing in batches, each batch must be dry-weighed separately.
- Measure out your dye, using 1 oz. of dye for every 1 lb. of dry weight material.
- Heat is a major factor in successful dyeing. A higher dyebath temperature increases the rate at which dye is absorbed. If you use cold water, you will not get the best color depth. Therefore, we recommend a dyebath temperature between 140º and 180º F.
- Timing is another factor for achieving successful results. We recommend immersing material in a dyebath for a minimum of 20 minutes and a maximum of one hour. Timing is consistent, regardless of the depth of color you desire. If you want a lighter color, use less dye. If you want a deeper color, increase the amount of dye you use. In either case, the time needed to dye is consistent regardless of the depth of color you want.
- When you remove your material from the dyebath, it is important to rinse well in cool running water until the rinse water is clear, in order to remove unbonded dye. Next, wash the dyed material with a mild detergent in cool water.
- We do not recommend reusing the dye – multiple dyeing in the same dyebath will not provide consistent color, even though the dyebath looks as if it still contains color.
- Dyes will bleed (color rubs off) for a variety of reasons including: (a) if it is overloaded (too much dye for the dry weight of the material); (b) if you did not use sufficient heat and time to dye your material; or (c) if you did not thoroughly rinse your material until the rinse water ran clear.
