A process is provided for dyeing textile materials in a solid shade with a jet injection dyeing apparatus, including conveying means for transporting the textile, jet orifices for delivering dye to said textile material, and control means for supplying data to control the operation of the application of dye from the jet orifices to the textile material, which comprises the steps of: modifying the textile material prior to dyeing of same by applying to said textile material an aqueous admixture containing an effective minor amount of a thickening agent to maintain the viscosity of said aqueous admixture at from about 150 to about 750 centipoises, preferably about 200 to about 400 centipoises, to thoroughly wet said textile material; dyeing said textile material in a solid shade with an acid dye composition having a viscosity of from about 150 to about 750 centipoises, preferably from about 200 to about 400 centipoises, by applying said dye composition by means of said jet injection dyeing apparatus in an amount of at least about 300 percent based on the weight of said textile material; the pH of the textile material at the point of contact between said dye composition and said textile material being maintained at from about 3.5 to about 7.5, fixing said dye on said textile material, washing said textile material to remove any unfixed dye, and recovering a resulting textile material dyed in a solid shade.
