Man, this conversation is a slow process! What
kind of Dylon dyes did you use?
Many of the dyes made by the Dylon company are
fiber reactive dyes. This includes Dylon Permanent, Dylon Cold, Dylon Machine, and Dylon Hand. Since these are all fiber reactive dyes, they will withstand boiling just fine, as long as you followed the instructions when you applied the dye, and used an adequate temperature and 100% cotton and all that, and used
soda ash fixative if you were using Dylon Cold. The only dye removed by boiling will be the unattached excess dye, which you have to remove anyway.
However, Dylon Multi Purpose Dye is an
all-purpose dye, like Rit or Tintex dye, so it is not bound permanently to the fiber and will tend to bleed badly in hot water. All-purpose dyes are very inferior to fiber reactive dyes, especially when used in batik.
