Definitions

  • the invention relates to a cleaning article, according to the preamble of patent claim 1 and a method for its preparation.
  • the US 3,073,716 describes a sponge body provided with an abrasive layer.
  • the DE 103 39 113 A1 shows a sponge cloth based on regenerated cellulose, which is colored with at least one reactive dye.
  • From the WO 94/04738 A1 is a nonwoven fabric with an abrasive layer known.
  • Such cleaning articles are known from DE 103 39113 A1 known.
  • the previously known cleaning articles are produced by the cellulose xanthate method. To produce cotton fibers are wetted with alkali and kneaded with viscose. Then Glauber's salt and colorants are added as needed and the mixture is then kneaded.
  • the invention has for its object to improve the cleaning performance of the cleaning article described above against firmly adhering dirt.
  • the base body is provided at least on one side with an abrasive layer.
  • the abrasive layer improves the cleaning performance of the cleaning article against firmly adhering soiling.
  • the firmly adhering dirt is released by the abrasive layer of the surface to be cleaned and absorbed in the cleaning liquid, which is bound in the cleaning article, and thereby removed from the surface to be cleaned. Due to the large amount of water that can be absorbed by the cellulose-based cleaning article, a gentle cleaning even of sensitive surfaces.
  • the abrasive layer consists of a binder and scouring particles.
  • a binder In principle, it is difficult to attach scouring particles to a cellulose-based base body, since the cellulose, for example, can not be locally melted to improve adhesion.
  • the scouring particles are firmly bound by a binder.
  • Possible binders are based on phenol resin, acrylate-based or consist of a mixture of phenol and acrylate. Such binders are present in an aqueous solution, some of which are in the Body penetrates causes a local swelling of the cellulose and firmly anchored after curing on the cellulose fibers.
  • Other conceivable binders may consist of latex, melamine resin, nitrile rubber or polyurethane or of mixtures of the abovementioned.
  • the scouring particles are formed by mineral and organic scouring particles.
  • mineral abrasives for example, quartz, silicon carbide, aluminum oxide, corundum, glass can be used.
  • Other conceivable abrasives consist of lime, chalk, silica, nut shells or Kunststoffstaffgranulate based on polyurethane, polymethylacrylate, polyacrylate, polycarbonate or rubber.
  • Polyacrylate is particularly suitable for the abrasive cleaning of sensitive surfaces
  • the abrasive layer comprises a thickener.
  • the thickener prevents the liquid constituents of the abrasive layer from penetrating into the base body too quickly when applied to the base body due to its high water absorption capacity, and before hardening.
  • Thickeners which give thixotropic properties to the solution on which the abrasive layer is based are particularly advantageous. Such thixotropic properties can be processed particularly advantageously in the spray process.
  • the solution is liquid by the action of shear forces in the spray apparatus and solidifies immediately after emergence, so that the solution has a high viscosity when hitting the base body, which limits the penetration depth of the solution. As a result, an abrasive layer having a significant thickness can be obtained.
  • Methacrylic acid-based thickeners have such advantageous thixotropic properties.
  • the abrasive layer can be made to be water-permeable so that the water absorbed in the cleaning article can reach the surface to be cleaned through the abrasive layer.
  • a base body consisting of a base of regenerated cellulose reinforced with cotton fibers is provided and provided with an abrasive layer.
  • the abrasive layer can be sprayed on or printed on.
  • the spraying is particularly easy to integrate into the manufacturing process and it is a high area performance possible.
  • Application rates of the abrasive layer of 200 to 300 g / m 2 are conceivable.
  • a printing paste is provided which contains a binder and a thickener, wherein the thickener is dosed in accordance with the printing process.
  • the abrasives are evenly distributed in the printing paste. It is also possible to provide a printing paste without abrasives. These first print on the surface of the body and then spread on the wet printing paste abrasives, which are thus mainly bound to the surface of the printing paste.
  • FIG. 1 shows a cleaning article 1, which consists of a base body 2.
  • This basic body 2 in turn consists of a base of regenerated cellulose and reinforced with cotton fibers.
  • the main body is on one side 4 over its entire surface with an abrasive layer 3.
  • the abrasive layer 3 consists of a binder 5 based on phenolic resin or acrylate provided with abrasives 6 based on glass particles or polyacrylate.
  • a base body 2 is composed of a base of regenerated cellulose, reinforced with cotton fibers, and provided with an abrasive layer provided.
  • the abrasive layer 3 can be applied to the base body 2 by means of spraying or printing.
  • the application of the abrasive layer 3 preferably takes place by means of spraying, the solution forming the abrasive layer 3 comprising a thickener based on methacrylate, so that the solution has thixotropic properties, ie can be sprayed easily and only penetrates into the base body 2 to a limited extent.
