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.

Method of dyeing or printing synthetic polyamide fibre materials using reactive dyes

Method for the trichromatic dyeing or printing of synthetic polyamide fiber material, wherein at least one red reactive dye of formulais used together with at least one of the yellow or orange reactive dyes of formulaeand at least one blue reactive dye of formulain which formulaethe variables are as defined in claim 1,which method is distinguished by a uniform color build-up and a very good combinability.

Method for the trichromatic dyeing or printing of synthetic polyamide fiber materials

A process for dyeing textile materials of naturally occurring and synthetic polyamide fibres, in which dyeing is carried out at the boiling point of the dyebath during a short dyeing time which is therefore gentle on the fibres, and level dyeings having good fastness properties are obtained (high temperature rapid dyeing process). The dyeing process is carried out with dyebaths with comprise specific surfactants. A high degree of exhaustion of the dye liquors is achieved, and dyeing from static baths is thus rendered possible.
