PURPOSE:To enable the title dye printing of high-concentration and clear expression without ink staining by containing 2 or more colors of reaction dyes different in their reaction rates and ink jet-printing the cloth with small ink drops satisfying specific conditions. CONSTITUTION:In the preparation of an ink containing 2 or more colors of reaction dyes different in their reaction rates, as the reaction rate of a dye in the ink becomes slower, the ink drop is jetted earlier and the surface tension of the ink containing a dye of slower reaction rate is made smaller, for example, the difference of adjacent drops is set more than 3 dyne/cm in the surface tension. Cellulosic fiber and/or polyamide fiber cloth, preferably containing an alkaline substance beforehand is jet-dyed with the prepared ink, heat-treated usually and washed to realize ink jet print dyeing developing high coloration with excellent level dyeing without ink staining even on ink color mixing to each other. |
