Definitions

  • the present invention relates to a method for textile care, in particular a method for textile care using an active ingredient composition in softened water.
  • the consumer When using detergents and cleaning agents, the consumer not only pursues the goal of washing and cleaning the objects to be treated, but also wishes to care for these objects to be treated, such as textiles, at the same time. Particularly relevant care procedures are fabric softening and the scenting of the objects to be treated. For this reason in particular, most of the commercially available detergents and cleaning agents contain fabric softeners or fragrances.
  • the care agents can be added to the detergents or cleaning agents in free form or in packaged form, for example in the form of active ingredient-containing microcapsules. The encapsulation can increase the stability of active ingredients such as the fragrances.
  • fragrances are highly volatile. For this reason, when conventional detergents or cleaning agents are used, only a small proportion of the care agent used remains on the treated object after use, in particular after washing. As a result, in the case of fragrances, for example, the treated object often emits only a weak fragrance. This can be remedied by special care products, which are primarily dosed into the washing drum in a separate form at the beginning of a wash cycle. In this way, the consumer can, for example by using scented lozenges, adapt the degree of scent of the washed laundry to his individual needs.
  • Scented lozenges are usually produced from melt dispersions, the main component of which is a water-soluble or water-dispersible detergent-active carrier material with a suitable melting temperature. From a sustainability point of view, the use of large quantities of carrier material, especially synthetic polymers, is in need of improvement. There is accordingly a need for alternative carrier systems and carrier materials for care substances, in particular fragrances.
  • the detergents that are already available are naturally suitable as such an alternative carrier, with liquid detergents, in particular transparent or translucent liquid detergents, enjoying increasing popularity.
  • liquid detergents in particular transparent or translucent liquid detergents
  • the present application was based on the object of providing methods for the care of textiles which make use of a visually appealing care product and are moreover characterized by a high level of effectiveness.
  • the method according to the invention can be carried out manually, but is preferably carried out with the aid of a washing machine.
  • the textile care device is a household washing machine.
  • a preferred textile care device for example in the form of a household washing machine, generally has a washing chamber, preferably designed in the form of a drum, for receiving the textiles to be washed, as well as a water supply line for charging the washing chamber with water.
  • the water introduced into the washing chamber is softened as it passes through the water supply line.
  • the textile care device in addition to a chamber for receiving the textiles to be cared for, the textile care device also has a water supply line by means of which water is introduced into the textile care device or the washing chamber, the water flowing through a device for reducing the water hardness before it enters the Chamber arrives.
  • the device for reducing the water hardness can be designed as an integral part of the textile care device or can be connected upstream of the textile care device, for example as part of a water pipe system.
  • the device for reducing the water hardness is preferably designed in such a way that the degree of hardness of the water supplied is reduced by at least 2 ° d, preferably at least 4 ° d, in particular by at least 10 ° d.
  • the water hardness reducing device used is preferably a cation exchanger which exchanges the hardness-forming ions of the supplied water, in particular Ca 2+ and Mg 2+ ions, for the equivalent amount of Na + ions.

  • the aqueous liquor in step c) has a degree of hardness in the range from 0 ° d to 4 ° d and in particular in the range from 0 ° d to 2 ° d.
  • the gel-like phase can in principle be introduced into the textile care device at different points in time of the method according to the invention.
  • the gel-like phase is introduced into the textile care device in step a).
  • the gel-like phase is introduced into the textile care device in direct contact with the textiles.
  • the gel-like phase can be applied directly to the surface of the textiles or introduced into the textile heap in the form of a prefabricated individual portion, for example in the form of an individual portion packed with water-soluble film.
  • the textile care device preferably also has a metering device, for example a metering chamber through which water can flow, with the aid of which the gel-like phase and / or the surfactant detergent described below can be metered into the washing chamber.
  • a metering device for example a metering chamber through which water can flow, with the aid of which the gel-like phase and / or the surfactant detergent described below can be metered into the washing chamber.
  • the gel-like phase is introduced into the aqueous liquor in step b), for example by means of the metering device described above.
  • the gel-like phase is introduced into the aqueous liquor only at a later point in time, for example in step c).
  • the above-described dosing device of the textile care device can again be used for this purpose.
  • the gel-like phase is used, for example, to post-treat the textiles after they have been cleaned beforehand.
  • a surfactant detergent is introduced into the aqueous liquor in the course of the method.
  • the surfactant detergent can be a solid or liquid detergent containing surfactants. However, it is preferred if the surfactant detergent introduced in step c) is liquid.
