Definitions

  • the present invention relates to the use of certain triazine derivatives as color transfer inhibiting agents in the washing of textiles and detergents containing such compounds.
  • detergents In addition to the ingredients indispensable for the washing process, such as surfactants and builders, detergents generally contain further constituents, which can be summarized by the term washing aids and which comprise such different active ingredient groups as foam regulators, graying inhibitors, bleaching agents, bleach activators and enzymes.
  • auxiliaries also include substances which are intended to prevent dyed textiles from causing a changed color impression after washing. This color impression change washed, i. Cleaner, textiles can be based on the fact that dye components are removed by the washing process from the textile ("fading"), on the other hand, from other colored textiles detached dyes on the textile precipitate (“discoloration").
  • the discoloration aspect may also play a role in undyed laundry items when washed together with colored laundry items.
  • detergents In order to avoid these unwanted side effects of removing dirt from textiles by treatment with usually surfactant-containing aqueous systems, detergents, especially if they are provided as so-called color or colored laundry detergents for colored textiles, contain active ingredients that prevent the detachment of dyes from the textile or At least the deposition of detached, located in the wash liquor to avoid dyes on textiles. Many of the commonly used polymers have such a high affinity for dyes that they draw them more from the dyed fiber, resulting in increased color losses.
  • triazine derivatives defined below lead to unexpectedly high color transfer inhibition when used in detergents. Particularly pronounced is the prevention of dyeing of white or other colored fabrics by washed out of textiles dyes. It is conceivable that the triazine derivatives, which are defined in more detail below, are applied to the textiles during washing and - possibly by their Sulfonic acid group portion - repellent to dye molecules in the liquor.

Abstract

Le ménagement des couleurs par des détergents lors de leur utilisation pour le lavage de textiles en couleurs devrait être amélioré. On parvient à ceci essentiellement en introduisant dans le détergent un dérivé de triazine non réactif portant des groupes sel d'acide sulfonique.
