Definitions

  • the invention relates to a detergent composition, a detergent portion and the use thereof for dyeing and washing textiles.
  • Detergents for textiles are well known from the prior art. Frequent washing of colored clothes is known to gradually wash out the colors and the laundry loses its color fastness.
  • Reactive dyes are characterized by the fact that they bind to the fiber through covalent bonds. This gives them a high wash fastness. Effective reactive dyes have to meet numerous requirements. For example, the dye molecules have to 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 suitable for forming covalent bonds with the fiber, in particular with free hydroxyl groups of cellulose molecules. Effective reactive dyes are therefore necessarily highly reactive towards nucleophiles and mostly 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 with the free hydroxy functionalities of cellulose, but also with other nucleophiles. This can result in a significant loss of reactive dye molecules.
  • water and especially hydroxide anions react with the dye molecules. This requires precise adjustment and control of the pH of the aqueous solution.
  • Direct dyes are dyes which are characterized by non-covalent, e.g. van-der-Waals or ionic interactions to which fiber is bound.
  • the dye molecules In order to color the fiber, the dye molecules must have a high affinity for the fiber to be colored.
  • the affinity of the direct dyes and thus the quality of the color is usually clearly pH-dependent. This requires precise adjustment and control of the pH of the aqueous solution.
  • Essential components of detergents are anionic and non-ionic surfactants as well as builders or builder substances and carbonates.
  • the detergent fleet, i.e. the aqueous detergent solution is usually basic.
  • Suitable detergent enzymes are added to modern detergents, which mostly break down contaminants through hydrolytic cleavage.
  • Amylases, lipases, cellulases and preferably proteases are used in detergents.
  • the pollutants are usually cleaved by reaction with particularly reactive nucleophilic groups in the active center of these enzymes.
  • nucleophilic groups for example, in the case of the well-studied serine proteases in the active center, there is a basic histidine side group in addition to the nucleophilic hydroxyl group of the reactive serine. 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 not only results in the efficient cleavage of dirt molecules, but also side reactions with any other molecules that may be present. Because of their mostly high nucleophiles, the enzymes used are particularly susceptible to undesirable side reactions with reactive groups, such as are present as anchor groups in reactive dyes. It is also known that reactive reagents covalently bind to the nucleophilic group of the enzyme binding and irreversibly inhibit the enzyme and thus render it unusable.
  • nucleophiles in the detergent fleet e.g. Hydroxy or surfactant anions, cleavage and thus rendering the reactive dye unusable, before it can bind to the fiber.
  • alkylating reagents can bind covalently to the nucleophilic groups of the detergent enzymes and thus irreversibly inhibit the enzymes and / or this leads to cleavage and thus rendering the reactive dye unusable before it can bind to the fiber.
  • Detergent compositions are known from the prior art, which may contain limited dyes. However, these dyes are only used to give the detergent a more visually appealing color, similar to how fragrances can be used to give the detergent composition a more pleasant smell.
  • the detergent compositions known from the prior art are not suitable for allowing already washed-out colors to be refreshed without significantly impairing the washing result.
  • US 2012/0108488 A1 discloses the combination of a direct dye and a reactive dye as laundry colorants, in particular a combination of 0.0003% by weight direct violet 9 and 0.06% by weight "S-ACMC” as well as a mixture of 0.0001 direct violet 9 (active ) with 0.01% by weight "S-ACMC”. These compositions are used in particular to improve cleaning and freshness in low temperature washes.
