I would like to use the acid dye to spray on treated nylon fabric what is a good mix to use and do I need to treat the material? Any help on this would be much appreciated. Thanks in advance!

Do you know what the nylon is treated with? Any coating on the fabric may prevent the dye from penetrating in to the fibers.

You will have to steam the nylon to fix the dyes so that the fabric is washable.... Dye-na-Flow may be a better choice as it is an acrylic paint and can be heat set with an iron or in the tumble dryer. DNF is more likely to adhere to a treated fabric as well.

Here is the recipe for acid dye as a paint.

Good luck

Acid Dyes for Painting:
Add 8 oz. (1 cup) of very hot water to one .5 oz. Acid Dye Powder. Stir until dissolved. This will yield a very concentrated dye solution. Most colors require further dilution. Note: every color has a different solubility. Some colors are difficult to dissolve such as 605 and 618, but most are easily dissolved. The final concentration of the dye solution for painting should be between 4 and 8%. Start by adding 4 oz. (1/2 cup) of water to the 8 ounces you already have, test the color and continue adding water until desired shade is achieved. Keep in mind that the color intensity really develops in the steam setting process. Most colors will remain stable in solution for a long period of time. However, some colors will fall out of solution upon cooling or from sitting for a matter of weeks. To restore them simply heat them on the stove. A small amount of alcohol (about 1 tablespoon) can be added to the dye solution as a wetting agent.
