Definitions

  • the invention relates to a cleaning cloth with a textile carrier material and a coating or impregnation thereon.
  • the cleaning cloth combines in a novel way good cleaning properties with good sliding properties.
  • the cleaning cloth also shows a very good cleaning effect for both hydrophilic and hydrophobic dirt.
  • the cleaning cloths may have a simple structure, for example by being formed from a monolayer textile base body. It is important for the cleaning cloth that it absorbs the dirt from the surface to be cleaned well and returns as completely as possible during the wringing process. In addition, the water absorption and delivery of the cloth is important. Water is needed on the one hand to dissolve adhering dirt, on the other hand so that the loosened dirt or loose dirt particles such as dust etc. are bound and removed with the cloth from the surface to be cleaned. Furthermore, the sliding properties of the cloth are important to the user.
  • textile carrier materials with a coating or impregnation.
  • textile materials can be provided with a polyurethane (PU) coating or impregnation.
  • PU polyurethane
  • the application of the PU coating or impregnating mass is carried out according to common practice of the type that the substrate is immersed in a solution of PU and dimethylformamide (DMF).

With the cleaning cloth also a very good cleaning effect should be achieved. In particular, the cleaning cloth should effectively absorb both hydrophilic and hydrophobic dirt from the surface to be cleaned. Next is the cleaning cloth the dirt, especially loose dirt particles, when flushing again can easily and easily.
  • the cleaning cloth should allow a gentle cleaning of objects or surfaces.
  • the coating or impregnation should show sufficient adhesion to the textile support material in order to have a corresponding mechanical stability during cleaning and in particular in machine washing.
  • a cleaning cloth which contains a textile carrier material comprising fibers of a hydrophobic material, in particular micro-filaments of a hydrophobic material, wherein the textile carrier material is a knitwear and has areas which are coated with a PVF foam, in particular a PVF foam.

  • the textile carrier material preferably consists at least proportionally of microfibers.
  • the textile carrier material consists of more than 60% by weight, more preferably 80% by weight to 100% by weight, of microfibers. This has a high water uptake capacity (e.g., in% over the dry weight of the fabric) despite the hydrophobic, and thus oleophilic, fibers due to the capillary action of the knitted microfiber yarns. Nevertheless, due to the oleophilicity of the microfiber material, an amphiphilic product can be obtained by combination with the hydrophilic PVF foam.
  • a further advantage of the cleaning cloth according to the invention is that it has hydrophobic materials in the form of the fibers of a hydrophobic material in combination with hydrophilic materials (PVF foam) and thus is amphiphilic as a whole.
  • the cleaning cloth according to the invention has a high cleaning effect both for oleophilic and for hydrophilic dirt, which makes it suitable for a variety of applications.

  • the hydrophilicity of the PVF material can be further increased when used in the form of a micro-foam.
