good for nylon, bad for cotton, very bad for tie-dyeing, May 17, 2006
All-purpose dye contains a mixture of an acid dye, which works on nylon, silk, and wool, but not on cotton, and a direct dye, which works rather poorly on cotton. It will not work at all on polyester, acrylic, or acetate. If you are dyeing cotton, you will be much happier with fiber reactive dye, because it is easier to use (no boiling water!), brighter and prettier in color, and much longer lasting in the laundry. Fiber reactive dyes sold by Amazon include Dylon Cold Water Dye, Dylon Permanent Fabric Dye, and, best of all, Jacquard Procion dye. Do a search on Amazon for those dyes now!
If you do choose to use all-purpose dye, first, be sure to buy enough. Each box will dye only one-half pound of fabric for a medium shade, or one-quarter of a pound of fabric for a very dark shade; for a pastel shade, you can dye one pound of fabric with one box. When dyeing nylon, silk, or wool, add six tablespoons of white vinegar per gallon of water; for cotton, do not use vinegar, which won't help, but do add one cup of salt. Using a cooking pot which you will never again use for food (Rit dye is not safe for utensils used in food preparation!), bring the dyebath to a good simmer, 190 to 200 degrees F. (87 degrees C.), add your garment, and continue to simmer for half an hour, stirring frequently. For solid colors, be sure to use a pot that is large enough to allow the garment to move freely.
Even when all-purpose dye is applied to cotton correctly, with simmering hot water, it still tends to wash out in the laundry and bleed on other clothing. To prevent both of these problems, you must apply a commercial dye fixative, such as Retayne or Raycafix; try a web search to find a place from which to order. Washfastness of items dyed with all-purpose dye is greatly improved by the use of the right fixative. Vinegar and salt will not make all-purpose dye on cotton last long in the laundry.

D'Black Beauty , October 13, 2007
I bought a black jacket at Singapore about two years ago and due to wear and tear of daily usage, the black became gray with dirty white spots. As I have experience in dyeing, I searched for black dye until I found this Rit Dye Black Powder and, WOW I have a Black Beauty.
