Use these dyes for dyeing protein fibers like Silk, Wool, Nylon. Acid dye is the best one for tub dyeing silk a solid even color. The Fluorescent yellow dye is also an Acid dye, and it glows in ultraviolet (black) light. Dharma Fiber Reactive Procion (the most economical) can be made into an "acid" dye by simmering it with vinegar for silk and wool, but colors can shift.
Pros: Acid Dyes are the dye of choice for solid color dyeing of silks, wools, alpaca, mohair and other protein fibers, as well as Nylon. Some folks even use them on leather, but test! Excellent prices, bulk pricing, handy 2oz size. 52 beautiful, vibrant, and some very hard to get colors! Can be painted on as well.
Cons: Needs hot, almost simmering, water to use or needs to be steamed. Some colors take more advanced dyeing technique.

Best dye for cotton, rayons, linens, hemp and other plant based fibers. Best dye for Tie-Dye and Batik. Vibrant wash fast permanent colors. Easy to use. Does not need hot water. Economical! Con's:
With silks and wools, colors are still vibrant, but shift. Need to use with the proper chemicals. Do not work on synthetics.
Pros: Historically fascinating to use dyes that have been in use for 100s to 1000s of years!
Cons: Fabrics or fibers have to be treated in a mordant before dyeing. Some of the metallic salts used to "mordant" (prepare for dyeing) the fabrics before dyeing are fairly toxic. We don't carry the worst ones.
