Abstract
Polyaramid fiber is swollen, such as by exposing it to a solvent, and while swollen a substance, such as amine or substituted amine, capable of forming an ionic bond with an acid or anionic dye, is introduced into the fiber, after which the fiber is shrunk, such as by drying, to incorporate the substance into it. Thereafter, the fiber can be dyed or printed with an anionic dye. A solution of the solvent and substance may be prepared, and the fiber contacted with the solution.
