  • Publication number: 20040034938
    Abstract: The present invention relates to a method for reducing dye loss or dye transfer from textile fibre materials or leather in the domestic sector, which comprises treating the textile fibre materials or the leather with a dye-fixing agent based on basic polycondensation products of an amine of formula (1) and a cyanamide, which polycondensation products are completely or partially neutaalised with an inorganic or organic acid, R1, R2, R3 and R4 each independently of the others being hydrogen or alkyl that is unsubstituted or substituted by amino, hydroxy, cyano or by C1-C4 alkoxy and A being alkylene optionally substituted or interrupted by one or more hereto atoms. The present invention relates also to new formulations comprising the dye-fixing agent and to new dye-fixing agents.

  • Patent number: 4851011
    Abstract: Concentrated aqueous dye formulations of water-soluble organic dyes are prepared by desalination and concentration of corresponding crude dye solutions by means of membrane separation processes. The effectiveness of the membrane separation process on the one hand and the stability of the dye formulations on the other hand is improved if dye solutions are subjected to cross-flow microfiltration before and/or after the membrane separation process and insoluble constituents are thus removed.

  • Patent number: 4838895
    Abstract: Concentrated aqueous dye formulations of anionic dyes are prepared from the corresponding crude dye solutions or suspensions, in which the anionic dyes are present as potassium, sodium/potassium or ammonium/potassium mixed salts, by desalinating and concentrating the solutions or suspensions by means of a membrane separation process. Sodium salts of mineral acids or lower organic carboxylic acids are added before or during this process in order to improve the solubility of the dyes and thus the stability of the dye formulations.
