Definitions

  • the present invention relates to a method which is particularly suitable for carrying out in commercial laundries and is based on the new development of a pasty detergent which is fed into the washing process by means of a metering system which has been specifically matched to this agent.
  • Liquid to pasty detergents are known in large numbers. These are generally tailored to household needs, i. H. they should be sufficiently liquid and easy to pour and dose. Since they should also be stable in storage within a relatively wide temperature range, it is usually not possible to do without the use of organic solvents and / or hydrotropic additives. However, these additives are washing-inactive, comparatively complex and additionally require packaging volume or transport and storage capacity. A content of volatile flammable solvents, which require additional safety precautions, is particularly troublesome. Detergent concentrates of the type mentioned are therefore not or only of limited use for laundries.
  • Paste-like, essentially water-free detergents are also known, for example from US-A-4,115,308 and US-A-3,850,831. They also regularly contain washing-inactive liquid additives, such as polyglycols or triethanolamine, for the purpose of dispersing the finely divided builder salts and adjusting the viscosity, so that they can be easily expressed from a tube by hand pressure to let. In this form, they are unsuitable for use in washing machines that are equipped with conventional detergent dispensers. If the paste is dosed into these chambers, it is not dissolved and dispersed by the water supplied, but a superficial gel layer forms around the paste, which hinders the further dissolving process.
  • washing-inactive liquid additives such as polyglycols or triethanolamine
  • the gel-like paste slides together with the flowing water into the lye drum, where due to its high specific weight it collects almost completely in the area of the drain nozzle and remains there practically until the end of the washing process. With the rinse water, the agent then enters the sewage system essentially unused.
  • Tubes are unsuitable for this type of application because they are only suitable for limited fill quantities and handling is therefore labor-intensive and time-consuming. In most cases, too large residual amounts remain on the tube wall and in the tube head.
  • the removal of viscous pastes from conventional storage containers by means of dosing spoons is also cumbersome and labor-intensive and moreover leads to the flushing problems already described.
  • Powder detergents are therefore mainly used in laundry companies. Since the exact dosing of such agents is problematic or labor-intensive, especially in large companies with extensive automation, the agents are usually stored and metered in pre-dissolved form as base liquors, i.e. an aqueous concentrate is prepared, which is then fed to the individual consumption points.
  • the detergents usually used in laundry companies contain comparatively high proportions of washing alkalis, which are only soluble in cold water to a limited extent and moreover have salting-out effects to lead. They cause phase separation, with the result that the organic components, in particular the nonionic surfactants and soaps, separate and cream.
  • European patent application EP 0 295 525 A2 published on December 21, 1988, describes a washing method for carrying out in commercial laundries, a pasty detergent being fed into the snacking process by means of a metering device specially adapted to this agent.
  • the metering device can consist of a follower plate driven by a pressure ram, which closes a container on one side, with the aid of which the paste-like agent is pressed into the removal line.
  • a mixing device which mixes the paste with water.
  • a dosing device for liquid detergents in which a double chamber is provided which is separated by a freely movable wall into two chambers, one chamber of which is designed as a dosing chamber and the second chamber of which is connected to the suction port of a wet jet pump is.
  • the dosing quantity is determined solely by the size of the dosing chamber.
