Definitions

  • the invention relates to a detergent composition, a detergent portion and use thereof for dyeing and washing textiles.
  • Detergents for textiles are well known in the art. Frequent washing of coloreds is known to cause a gradual washout of the colors and the laundry loses color fastness.
  • Reactive dyes are characterized by the fact that they bind to the fiber by covalent bonds. This gives them a high wash fastness. Effective reactive dyes must meet many requirements. For example, the dye molecules must be water-soluble and absorb in the desired wavelength range. In order to be able to bind to the fiber, the dye molecules have one or more identical or different anchor groups. These anchor groups must be capable of forming covalent bonds with the fiber, especially with free hydroxy groups of cellulose molecules. Effective reactive dyes are thus necessarily highly reactive towards nucleophiles and most suitable "alkylating agents".
  • the high reactivity of the reactive anchor has the disadvantage that the reactive dye molecule can react not only with the textile fiber, ie the free hydroxy functionalities of the cellulose, but also with other nucleophiles. This can lead to a significant loss of reactive dye molecules.
  • a reaction of water and in particular hydroxide anions takes place with the dye molecules. This requires the precise adjustment and control of the pH of the aqueous solution.
  • Direct dyes are dyes characterized by non-covalent, e.g. van der Waals or ionic interaction interactions to which fiber is bound.
  • the dye molecules In order to achieve a coloration of the fiber, the dye molecules must have a high affinity for the fiber to be dyed.
  • the affinity of the direct dyes and thus the quality of the dyeing is usually significantly pH dependent. This requires accurate adjustment and control of the pH of the aqueous solution.
  • Essential constituents of detergents are anionic and nonionic surfactants as well as builders or builders and carbonates.
  • the detergent liquor, i. the aqueous detergent solution is usually basic.
  • Modern detergents are added to suitable detergent enzymes which degrade contaminants mostly by hydrolytic cleavage.
  • detergents especially amylases, lipases, cellulases and preferably proteases are used.
  • the cleavage of contaminants is usually by reaction with particularly reactive nucleophilic groups in the active site of these enzymes.
  • nucleophilic groups for example, in the case of the well-studied serine proteases in the active center, besides the nucleophilic hydroxyl group of the reactive serine, there is a basic histidine side group. This histidine residue has an activating effect on the nucleophiles of the hydroxyl group of the serine residue.
  • the high reactivity of the nucleophilic hydroxyl group causes not only the efficient cleavage of dirt molecules, but also side reactions with possibly existing other molecules. Due to their usually high nucleophiles, the enzymes used are particularly susceptible to undesirable side reactions with reactive groups, such as those present as anchor groups in reactive dyes. It is also known that reactive reagents covalently bind to the nucleophilic group of the enzyme and irreversibly inhibit the enzyme and thus render it useless.
  • reactive dyes as colorants with detergents suggests that it may be enhanced by nucleophiles in the detergent liquor, e.g. Hydroxy or surfactant anions, cleavage and thus to make unusable the reactive dye before it can bind to the fiber.
  • nucleophiles in the detergent liquor e.g. Hydroxy or surfactant anions
  • Detergent compositions which may contain limited dyes are known in the art. However, these dyes are merely used to give the detergent a more visually pleasing color, much as fragrances can be used to impart a more pleasant odor to the detergent composition. However, the detergent compositions known from the prior art are not suitable for enabling freshening of already washed-out colors without significantly impairing the washing result.
  • the object of the present invention is therefore to provide a detergent composition and a process which are suitable not only to largely avoid a loss of color fastness, but in particular to enable a refreshing of already washed out colors without substantially impairing the washing result Wash off the refreshed paint in the following washes.

  • Reactive Black 5 was used as a reactive dye in an amount of about 10% by weight, and Direct Black 22 as a direct dye in an amount of about 10% by weight. It was sodium metasilicate in an amount of about 30 wt .-%, zeolites in an amount of about 10 wt .-%, anionic and nonionic surfactants in an amount of about 20 wt .-%, soaps in an amount of about 5 Wt .-%, enzymes in an amount of about 1 wt .-%, trilone in an amount of 5 wt .-%, and sodium carbonate used in an amount of about 20 wt .-%.

  • Zeolites in an amount of about 1% by weight

  • trilon was in an amount used by about 0.2 wt .-%.
  • sodium chloride was adjusted to 100 wt .-%.
  • Reactive Black 5 as a reactive dye in an amount of about 1% by weight
  • Direct Black 22 as a direct dye in an amount of about 0.8% by weight. It was sodium metasilicate in an amount of about 5 wt .-%, zeolites in an amount of about 2 wt .-%, anionic and nonionic surfactants in an amount of about 2 wt .-%, soaps in an amount of about 0 , 5 wt%, enzymes in an amount of about 0.1 wt%, trilon in an amount of about 1 wt%, and sodium carbonate in an amount of about 3.4 wt% , Sodium chloride was used in an amount of about 82.2% by weight and sodium sulfate in an amount of about 2% by weight.
  • Fig. 1 A and B show photographic results of the comparative experiments described.
  • compositions were examined. All compositions contained 450 g of sodium chloride (about 80% by weight), 50 g of metasilicate (about 9% by weight) and 56 g of " Ariel® Color” (about 10% by weight). " Ariel® Color” is a detergent composition known to those skilled in the art.
  • Composition 1 also contained 5 grams (about 1 weight percent) Remazol Deep Black N 150 (Reactive Black 5).
  • Composition 2 contained 4 g (about 1% by weight) Sirius Black VSF / hc (Direct Black 22).
  • Composition 3 contained both 5 grams Remazol Deep Black N 150 (about 1 weight percent) and 4 grams Sirius Black VSF / hc (about 1 weight percent).
  • Fig. 1 A shows the result of washing a "plain" cotton sheet.
  • Fig. 1 B shows the result of the laundry of mercerized cotton (tablecloth fabric). It can be seen that composition 3 gives the best dyeing result in both test series. Thus, color fastness and hiding power of composition 3 is improved, not only in comparison with the result according to compositions 1 and 2 taken alone, but also in comparison with their (imaginary) superposition.
