  • Method of dyeing or printing synthetic polyamide fibre materials using reactive dyes
    Patent number: 7396370
    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.
    Type: Grant

  • Method for the trichromatic dyeing or printing of synthetic polyamide fiber materials
    Patent number: 6930179
    Abstract: Method for the trichromatic dyeing or printing of synthetic polyamide fiber material, wherein at least one red reactive dye of formula is used together with at least one of the yellow or orange reactive dyes of formulae and at least one blue reactive dye of formula in which formulae the variables are as defined in claim 1, which method is distinguished by a uniform color build-up and a very good combinability.

  • Process for dyeing naturally occurring or synthetic polyamide fibres
    Patent number: 5540739
    Abstract: 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.
