Definitions

  • the present invention relates to a cleaning material in the form of a planar-like structure, to whose surface one or more host substances are applied which can contain and release one or more active components, to a process for the preparation of this cleaning material, and to the use of the cleaning material as cleaning cloth for the dry cleaning of hard surfaces and as cleaning cloth for the dry cleaning of textiles.
  • the cleaning of substrates in the household generally takes place using water and corresponding cleaning compositions, irrespective of whether they are textiles, hard surfaces or other substrates.
  • aqueous solutions is not always desired particularly in the case of substrates which are sensitive to water.
  • the use of aqueous application solutions involves firstly having to prepare the corresponding cleaning liquors and then having to remove them again from the substrate. Particularly for textiles and textile surfaces, a relatively long drying operation is associated with this.
  • compositions are also known which are applied to the substrate to be cleaned without the further addition of water and are removed again using a cloth.
  • a cloth which have an antistatic finish or have long fibers. Examples of such cloths are the standard commercial dusters or linen cloths, as are used for the polishing of glass, etc. They usually do not contain active substances.
  • German patent application DE 40 35 378 A1 ( ⁇ Dre Eckstelle und Textilinstitut für fast Kausch) describes a textile material with a finishing applied thereto. This finishing is fixed to the material chemically or physically and consists of at least one cyclodextrin and/or cyclodextrin derivative. It is disclosed that the textiles finished in this way have a good water absorption capacity and thus lead to a relatively high wear comfort for the textiles, and that soilings etc. are also taken up by the cyclodextrins. The soilings should thus not come into direct contact with the textile and be readily transferable to the wash liquor during the washing or cleaning. The use of the described finished textile materials for the cleaning of substrates is not disclosed.
  • the present invention accordingly provides a textile cleaning material in the form of a planar-like structure, to whose surface one or more host substances are applied which can contain and release one or more active components, where the host substances are bonded chemically and/or physically to the surface of the planar-like structure.
  • soilings are the customary soilings which are visible as stains and also odor substances, such as tobacco smoke, perfume residues, perspiration or perspiration degradation products, mustiness, etc. Particularly on hard surfaces there is also often finely distributed dust or invisible soilings, which may also include microorganisms.
  • cleaning used in this application covers both the removal of visible and invisible soilings and also the removal of odor substances.
  • the cleaning material according to the invention is a planar-like structure on whose surface one or more host substances are bonded which can contain and release one or more active components.
  • the structure has a two-dimensional form and can, in customary language usage, also be referred to as a cloth.

Bonds with bond energies greater than 5 kJ/mol, preferably greater than 10 kJ/mol, particularly preferably greater than 30 kJ/mol and in particular greater than 50 kJ/mol are particularly suitable.
  • the bond between the host substances and the surface of the textile fabric may be covalent or ionic or be based on van der Waals' interactions.
  • the bond between the surface of the planar-like structure and the host substance has the advantage that the active component is in complexed form prior to use of the cleaning material and is thus protected from premature release, and that the complexing substance, i.e. the host substance, is not detached or is detached only to a small degree during application. After the active component has been released, the host substance can complex released soilings.
  • Host substances which can be used for the active components are any substances which are able to take up or bind in a complex the active components, and also release these components again.
  • the host substances preferably have polar groups or functional groups. Examples of functional groups are OH, COOH, NH 2 or other acidic or basic groups.

  • the cyclodextrins or cyclodextrin derivatives are constructed from 5 to 12 glucose units.
  • a broad spectrum of different cavity diameters of the individual cyclodextrins is offered, meaning that differently sized substances can also be inserted into these cavities.

  • the surface of the carrier material has functional groups via which the host substances can be bonded via chemical bonds, optionally via so-called spacers, preferably bifunctional compounds or polymeric compounds.
  • suitable functional groups are OH, NH, NH 2 , COOH, CHO, SO 3 H, epoxide or other acidic and/or basic groups, and also triazine.
