Definitions

  • the present invention relates to reactive dye compounds.
  • the present invention relates to reactive dye compounds having improved dye- bath Exhaustion (E) and improved dye-fibre covalent Fixation (F).
  • Reactive dye compounds are known in the art for dyeing various substrates.
  • substrates include for example proteinaceous materials such as keratin, e.g. found in hair, skin and nails and various animal body parts such as horns, hooves and feathers, and other naturally occurring protein containing materials, e.g. silk and saccharide-derived materials such as those derived from cellulose or cellulose derivatives, e.g. natural products such as cotton, and synthetic fibres such as polyamides.
  • Examples of classes of such reactive dyes which are well known in the art include dyes containing a mono- or dichloro- or fluoro- 1,3,5-triazinyl group, mono- or dichloro or fluoro-pyrimidyl group, beta-halogen-propionyl group, beta-halogenoethyl-sulphonyl group, beta-halogenoethylsulphamyl group, chloroacetyl amino, beta-(chloro-methyl)-beta- sulphatoethylsulphamyl group, or a vinyl sulphonyl group.
  • the Fixation Value (F) of a dye compound is a measure of the dye affinity at the substrate surface.
  • a high Fixation Value can result in a simplification of the post dyeing "soaping off process" traditionally associated with fiber reactive dye compounds.
  • a high Fixation Value can result in a reduced time spent on the "soaping off process” together with a reduced cost.
  • a new class of fibre reactive dye compounds comprising a nitrogen-containing heterocycle such as pyrimidine substituted with at least one quatemized nitrogen derivative such as nicotinate, exhibit significantly increased values of Exhaustion (E) and Fixation (F).
  • E Exhaustion
  • F Fixation
  • These dyes can be used on a wide variety of substrates. They are particularly useful for cellulosic substrates, such as cotton, and show significant improvements in terms of reducing spent dyestuff in effluent, increasing dye affinity to the substrate, and simplifying the post dyeing "soaping off process" traditionally associated with reactive dyes.
  • the compounds of the present invention provide significantly more intense dyeings, and can be used for both high and low temperature dyeing, hence reducing the cost of the dyeing process.
  • the compounds of the present invention can be used together with specific chromophores for cellulose substrate dyeing leading to significantly reduced levels of salt needed for dyeing.
  • the compounds of the present invention exhibit increased Exhaustion (E) and Fixation (F) values and provide improvements in terms of reducing spent dyestuff in effluent, increasing dye affinity to the substrate, simplifying the post dyeing "soaping off process" traditionally associated with fiber reactive dyes and ability to dye at room tenperature and elevated temperatures.

Thus 100% Exhaustion means that 100% of the dye is transferred from the dye solution to the substrate.
  • Fixation in relation to reactive dyes means the percentage of dye which covalently bonds with the substrate, based on the dye originally absorbed during the dyeing process. Thus 100% Fixation means that 100% of the dye absorbed is covalently bonded with the substrate.

Abstract

L'invention concerne un colorant réactif ayant une valeur de fixation (F) sur des substrats à 95 % ou plus de cellulose du type de ceux mesurés par le test technique d'identification de la valeur de fixation (à une profondeur standard de 2:1). Les composés précités présentent, en outre, des valeurs d'épuisement (E) et des valeurs d'efficacité (T) élevées et font preuve d'améliorations importantes en termes de réduction de produits colorants épuisés dans les effluents, d'augmentation de l'affinité du colorant au substrat, d'augmentation de la liaison en covalence colorant-substrat, d'augmentation de la capacité à colorer des substrats à une température ambiante, de réduction de la quantité du colorant qui est éliminée pendant le 'processus de savonnage' après la coloration associée d'ordinaire à la coloration du coton avec des colorants réactifs à la fibre et de réduction de teinture de tissus blancs adjacents. Les composés préparés assurent des colorations plus intenses et nécessitent des niveaux inférieurs de sel pour colorer des substrats en coton.
