Definitions

  • the invention relates to a method for intensifying Washing processes using a contact material.
  • Wash-active, soap-based water soluble or not Soap detergents are available in a variety of Connections known. This includes, for example surface-active, non-soap-containing cleaning agents at least one component comprising carbonates, for example carboxylic acids or their salts. Furthermore is a variety of other organic or inorganic Compounds known as cleaning or washing agents, especially soaps from fatty acid condensation products.
  • cleaning or washing agents especially soaps from fatty acid condensation products.
  • On all active washing detergents that are soluble in washing water common disadvantage is that they are to achieve a satisfactory purity of textile laundry or Dishes must be dosed relatively high. This creates a wash liquor, the remains of which are very intense and multiple repeated rinsing must be rinsed off the laundry, whereby a high water consumption and a correspondingly high Wastewater is caused.
  • the invention is based on the object of a method for gentle intensification a washing process by means of the laundry - e.g. B. Textiles or tableware - contact material to be provided, which in the Interaction with common cleaning agents, their cleaning power clearly strengthened, as a result of which their required amount was significantly reduced, at the same time significantly reduces water consumption and wastewater and overall, therefore, to protect the laundry, protect the skin, reduce the harmful precipitation of lime-carbonate on washing machines and leads to a reduced environmental impact.
  • the solution to the problem is in a method of the aforementioned Art achieved with the invention in that to lower the surface tension of the water (relaxation of the water surface with change the adhesive and cohesive forces) and to optimize the carbonate hardness, Total hardness and the pH value of the water as contact material at least one surface-active polycarbonate body in the form of Thermoplastic material is used, which has any shape and for example as cylinder, disc, cube, prism, cuboid, polyhedron, sphere, Spherical section, ellipsoid or hollow body is formed and in a liquid-permeable Packaging is used.
  • An embodiment of the method provides that the washing powder Flushing process is carried out with liquid that except Water only very small proportions of cleaning or Detergent and possibly less softening and / or Contains relaxants, and that as a contact body Polycarbonate in solid form added as a thermoplastic material become.
  • the polycarbonate bodies also remain with advantage repeated use unchanged in their effect, i.e. she show no signs of wear.
  • Any shapes can be used as contact bodies Cylinders, disks, cubes, prisms, cuboids, polyhedra, spheres, Ball sections, ellipsoids, hollow bodies or similar be used, preferably disc-shaped cylinders with a diameter of approx. 5 cm and a thickness of 1 cm.
  • the active surface and / or amount of Polycarbonate material according to the carbonate hardness, Total hardness and pH of the water can be measured.
  • the use of at least one serves Contact body made of polycarbonate material in the wash water gentle intensification of the washing power of a water and Cleaning liquid containing detergent.
  • the measures and refinements according to the invention are not based on the described embodiments limited. Possible modifications of the The method according to the invention can consist of others Workpiece shapes are used, with a dependence on the surface exists, especially as a function of the amount of water and the degree of turbulence. The respective design is being adapted the specialist is free for special uses.
