Abstract: Process for alkali-free dyeing and printing with reactive dyes. Beforehand, the textile material is treated with a wetting agent and a reaction product of polyethyleneimine and a bifunctional alkylating agent. This is followed by dyeing with reactive dyes in a conventional manner but without the addition of alkali to fix the dyes.
