Definitions

  • the invention relates to a scouring body comprising a fabric provided with a scouring composition, the scouring composition comprising a binder and scouring particles, the fabric comprising a cleaning surface having a relief pattern.
  • a scouring body which has as a carrier material a textile fabric which is provided with a scouring composition.
  • the textile fabric consists of a nonwoven fabric which has been mechanically consolidated by needling or by water jet.
  • a scouring composition comprising a chemical binder and abrasive particles.
  • the previously known scouring body is suitable for absorbing or absorbing aqueous substances and for loosening firmly adhering soiling due to the abrasive effect of the scouring composition.
  • the invention has for its object to provide a scouring body with a more effective power transmission.
  • the fabric is arranged on a sponge body.
  • the textile fabric is formed as a nonwoven fabric made of synthetic fibers and preferably solidified by means of water jet.
  • the thickness of the sheet is between 0.8 and 3 mm and the basis weight is between 50 and 200 g / mm 2.
  • Such fabrics have a low basis weight and a small thickness with high tensile strength.
  • the sponge body forms a support body which offers a variety of grip options. As a result, in various ways, effective force can be exerted on the fabric provided with the scouring composition so that a good cleaning performance against firmly adhering contaminants results.
  • the relief pattern additionally improves the cleaning action of the scrubbing body.
  • the relief pattern may be formed by a nub structure, wherein the nubs are arranged hexagonally. This will prevent the dirt from adding to the abrasive surface as the dirt collects between the dimples in the recesses, thereby not affecting the scrubbing process.
  • the sponge body may be formed of an open-cell plastic foam or a natural foam.
  • the foam can be formed in particular of polyurethane or viscose. Foams made of these materials are inexpensive to produce and have good mechanical properties, so that they are easy to grasp and can transmit forces. Viscose has a high water absorption capacity.
  • the scrubbing body is preferably cuboid and has two major surfaces. Then, on a first major surface, the sheet with the abrasive composition is disposed. On the second main surface opposite the first main surfaces, the further textile fabric is arranged.
  • This sheet preferably also consists of a nonwoven fabric with synthetic fibers, wherein the nonwoven fabric is formed so that the further fabric has a high water absorption. The second main surface then serves for the aftertreatment of surfaces which have already been cleaned with the first main surface and for the absorption of liquids.
  • the further fabric may comprise microfibers.
  • Microfibers have a fiber diameter smaller than 1 ⁇ m.
  • the microfibers used have a high absorption capacity for liquids such as water and fats.
  • the scouring composition may comprise glass granules.
  • Glass granules have a high hardness and are particularly suitable for cleaning glass or ceramic surfaces, such as glass ceramic cooktops or slices of stoves.
  • the binder may be latex, phenolic resin and / or acrylate based.
  • a phenolic resin-based binder has high hardness, high abrasion resistance.
  • the binder may be acrylate-based.
  • Acrylate-based binders have a pleasant feel.
  • Latex-based binders have a high elasticity. Blends of latex and phenolic resin binder have by the phenolic resin a high flexural rigidity, wherein the bending stiffness is reduced by the latex content so far that the abrasive body can be wrung well.
  • the binder may consist of a mixture of acrylate and phenolic resin. The properties of both binder materials then influence the feel and hardness of the material.
  • the binder may be formed on the sheet such that the sheet is substantially impermeable to water.
  • a film of cleaning liquid remains between the fabric having the abrasive composition and the surface to be cleaned. Dirt is dissolved in the cleaning fluid and it results in a gentle and effective cleaning of the surface to be cleaned.
  • the binder may also be formed so that the sheet is rigid. This results in a particularly good power transmission and an improved cleaning effect against firmly adhering dirt.
  • Other possible binders are melamine resin, nitrile rubber, polyurethane or compounds of all the binders mentioned.
  • the sponge body may be formed quadrangular, wherein the edges have a curved contour. As a result, hard to reach areas can be effectively cleaned. It results in a variety of different grip options.
  • the mutually opposite edges can be congruent with each other.
  • the scouring body is usually made of a flat Precursor produced by punching. In this shaping results in a lossless and therefore cost-effective production of abrasive bodies with curved edge design.
  • the scrubbing body may have a thickness of 2 to 5 cm. In particular, with a thickness of the scrubbing body of 4 cm, many grip options and a good power transmission.
  • the above-described scouring body is particularly suitable for use for cleaning glass and / or ceramic surfaces due to its advantageous embodiment.
  • FIG. 1 shows a scrubbing body 1 in particular for cleaning glass and / or ceramic surfaces.
  • the scrubbing body 1 consists of a textile fabric 2, which forms a cleaning surface 6 with a relief pattern 7 formed by protruding knobs.
  • the fabric 2 is arranged on a sponge body 8 and connected by an adhesive bond cohesively thereto.
  • the sponge body 8 is formed in this embodiment of an open-cell polyurethane foam.
  • the Scrubber body 1 is square and the edges 10, 11, 12, 13 of the scrubbing body 1 have a curved contour, wherein the opposing edges 10 and 11 and 12 and 13 are each formed congruent.
  • the scrubbing body 1 has a thickness of 4 cm.
  • On the cleaning surface 6 opposite side of the sponge body 8, a further textile fabric 9 is arranged, which comprises microfibers having a fiber diameter less than 1 micron.
  • the further fabric 9 is also bonded by means of an adhesive bond with the sponge body 8.
  • FIG. 2 shows the scrubbing body 1 according to FIG. 1 in another view.
  • the fabric 2 consists of a water jet-bonded nonwoven fabric made of synthetic fibers with different surface weights between 50 and 200 g / m 2 .
  • the fabric 2 is provided with a scouring composition 3, which in turn comprises a binder 4 and scouring particles 5.
  • the binder 4 in this embodiment consists of a composition of latex and phenolic resin.
  • the scrubbing particles 5 consist of glass granules.
  • the composition of the binder 4 is selected so that the sheet 2 is waterproof and rigid and can be wrung out well.
  • the properties of the binder 4 can be done by a subsequent heat treatment.
  • the total thickness of the sheet 2 is between 0.9 and 2 mm.
  • a textile material 2 formed by a nonwoven fabric, is first produced from a fibrous material.
  • the solidification of the textile fabric 2 takes place by means of a hydroentanglement.
  • the shaping of the cleaning surface 6 takes place in the same method step.
  • the relief pattern 7 with the nubs is likewise produced by the hydroentanglement.
  • the abrasive composition 3 is prepared by mixing the binder composition 4 made with abrasive particles 5 of glass granules.
  • the scouring composition 3 is applied to the cleaning surface 6 by spraying.
  • the sheet 2 may be heat treated to cure the abrasive composition 3 in an oven.
  • the fabric 2 is adhered to a sheet-like precursor consisting of an open-cell polyurethane foam.
  • the float 8 may also consist of viscose.
  • On the opposite side another sheet 9 is glued. Subsequently, the scouring body 1 with the curved edges 10, 11, 12, 13 are punched out of the flat precursor.
