ABSTRACT:
A method of dyeing or printing synthetic polyamide fiber materials, wherein (a) the fiber material is dyed or printed with at least one reactive dye, and (b) the dyed or printed fiber material is subjected to after-treatment with a reducing agent, the fiber material not being treated with polycondensable or polymerizable compounds for fixing the dye on the fiber, results in dyeings and printings that are distinguished by good fastness properties.
