Dyeing cotton black


A Few Things About Black Dye:

Black can be the hardest color to get. We currently have 5 blacks. Each has a different color cast. All except #250 work well in direct application methods like tie-dye where the fabric is kept moist long enough for the dye to develop full color. Always remember to quadruple the dye when using black, and use 1.5 - 2 times as much salt.

#44 Better Black
This is one of our best-selling blacks. Solid Color (tub) dyes with a purple-blue cast and edges are blue in tie-dye. Not black on silk or wool.

#39 Black
Tub dyes with a grayish-green cast and edges are blue in tie-dye. Not black on silk or wool.

#300 New Black
Our other best selling black - tub dyes with a very blue cast and edges are blue in tie-dye. Some of our good tie-dye customers say mixing a 50/50 blend of #44 & #300 gives them good results (test different ratios to see what you prefer). Not black on silk or wool.

#250 Jet Black
Our darkest black for tub dyeing. BACK by popular demand; But the price did go way up, as we had said it would. Also, one of the ingredients was no longer available, so we had to reformulate it. This color runs a little different than what you were used to, so if you want to go back to this color, we recommend TESTING before you go whole-hog and purchase a very expensive 25 pounder or something!!! Best tub dyed in hot (130° to 150°F) water! Not black on silk or wool or other protein fibers. Not black in tie-dye, batik or low immersion techniques unless you have a way of heating it while it is curing. (But that would melt the wax with Batik).

#275 Hot Black - NEW!
Also best tub dyed in hot (150° to 180°F) water, like the #250, which it was replacing. Now it is a less expensive alternative. Tub dyes with a deep but bluish black cast on cotton. With Soda Ash on silk is a deep blackish brown, with vinegar on silk, came out black in our tests and a less deep shade of black on wool. #250 Jet has never come out black on silk or wool. Tie-dye came out really black for us in a warmish ambient room temp of 75°F or more! (unlike #250, which it was replacing). If you are looking for a different black, give it a try. The only Fiber Reactive black that works on silk! Also our BEST black for Discharging!

For best tub dyed blacks, use Dharma Dye Fixative in a final soak in HOT water for 30 minutes before washing out the excess dye. Black is a tough color - you have to use a lot of dye and when tub dyeing, use 1.5 to 2 times the salt! Do NOT use Fiber Reactive Procion Dye to get black on silk, use acid dye on wool and silk for solid black. Exception - try our NEW #275 Hot Black!
