Definitions

  • the washing performance-enhancing effect of the active ingredients to be used according to the invention occurs in the next washing process, even if, if desired, a detergent without an active ingredient to be used according to the invention is used again.
  • a detergent without an active ingredient to be used according to the invention is used again.
  • the active ingredient essential to the invention is added in the fabric softener cycle, in particular for machine laundry.
  • the use according to the invention in the context of a laundry aftertreatment process can accordingly take place in such a way that the soil-releasing active ingredient of the washing liquor is removed is added separately, which is used after the wash cycle carried out using a detergent, or it is incorporated as a component of the laundry aftertreatment agent, in particular a fabric softener.
  • the detergent used before the laundry aftertreatment agent can also contain an active ingredient to be used according to the invention, but can also be free of this.
  • the relative molecular weight of the homopolymers of unsaturated carboxylic acids is generally between 5000 g / mol and 200,000 g / mol, that of the copolymers between 2000 g / mol and 200,000 g / mol, preferably 50,000 g / mol to 120,000 g / mol, based on the free acid .
  • a particularly preferred acrylic acid-maleic acid copolymer has a relative molecular weight of 50,000 g / mol to 100,000 g / mol.
  • these polyesters composed as described above can also be end-group-capped, with possible end groups being alkyl groups with 1 to 22 carbon atoms and esters of monocarboxylic acids.
  • the end groups bonded via ester bonds can be based on alkyl, alkenyl and aryl monocarboxylic acids having 5 to 32 carbon atoms, in particular 5 to 18 carbon atoms.
  • polyester-active soil-releasing polymers are preferably water-soluble, the term "water-soluble" having a solubility of at least 0.01 g, preferably at least 0.1 g of the polymer per liter of water at room temperature and pH 8 should be understood.
  • polymers used with preference have a solubility of at least 1 g per liter, in particular at least 10 g per liter, under these conditions.
  • the fatty acids and the triethanolamine can generally be used in a molar ratio of 1.1: 1 to 3: 1.
  • a use ratio of 1.2: 1 to 2.2: 1, preferably 1.5: 1 to 1.9: 1 has proven to be particularly advantageous.
  • the esterquats used with preference are technical mixtures of mono-, di- and triesters with one average degree of esterification of 1.5 to 1.9 and are derived from technical C 16/18 tallow or. Palm fatty acid (iodine number 0 to 40).
