Definitions

  • the present invention relates to an article for cleaning hard surfaces comprising an adhesive.
  • the adhesive is able to quickly trap and retain dust, lint, hairs, sand, food crumbs, grass and the like.
  • said adhesive is able to retain those particles and hairs which are normally not captured by usual articles not comprising an adhesive and which need to be collected with a vacuum cleaner or a broom. This is achieved by carefully selecting the chemical composition and rheological characteristics of the adhesive.
  • Hard surface cleaning articles comprising an adhesive to retain particles and hairs are known in the art.
  • PCT patent application WO 01/62132 by The Procter & Gamble Company describes cleaning sheets comprising an additive that enhances the pick up and retention of particulate material from surfaces, while minimizing the amount of residue left on the surface being cleaned.
  • Adhesives are mentioned among the additives which can be used.
  • the mentioned application also describes a cleaning implement comprising a mop head having a resilient bottom surface, a portion of which preferably has a substantially smooth curved profile or crown which engages a removable cleaning sheet.
  • the application also describes how the adhesive can be applied to the cleaning sheet only in selected zones, in order to avoid excessive tackiness and preserve the ability of the cleaning sheet to smoothly glide across surfaces
  • Patent application WO 03/075735 by 3M Company describes a wipe for capturing ordinary dust or dirt and heavier particles such as sand that includes a wiping member having discrete valleys and peaks, and wherein an adhesive is provided in the valleys and not on the peaks.
  • the adhesive can contact a surface sufficiently to pick up sand and other heavy particles, but not to so great a degree that the coefficient of friction between the wipe and the surface is unduly high, which can make wiping difficult.
  • US 6,550,092 from S.C. Johnson describes a cleaning sheet including a fabric layer with a plurality of cavities secured to a flexible backing layer so as to define an outer fabric surface with a plurality of cavities therein.
  • the cavities can include a tacky bottom surface capable of enhancing the retention of dust and other particles. Cleaning implements and methods of cleaning surfaces using the cleaning sheet are also described.
  • the hard surface cleaning articles described in the prior art can be further improved, especially as concerns their efficiency in capturing and retaining particles and hairs.
  • hard surface cleaning articles comprising generic adhesives. We have surprisingly found that by selecting a specific range of adhesive materials having peculiar rheological properties, hard surface cleaning articles can be obtained having an improved efficiency of particles/hairs pickup. This translates in a much easier handling of the article, in a faster cleaning action and also in more effective cleaning, including the ability of collecting bigger particles.
  • the present invention relates to a hard surface cleaning article comprising an adhesive having: a.
  • the present invention relates to a method of cleaning a hard surface which comprises contacting said surface with an article comprising an adhesive as described above.
  • a further embodiment of the present invention relates to the use of an article comprising an adhesive as described above, for cleaning a hard surface in order to remove more effectively big particles and hairs.
  • the characteristics which have been considered in this context are the elastic modulus G' describing the elastic behaviour of the material and the viscous modulus G" which describes the viscous behaviour of the adhesive material.
  • G' and G" are measured in Pascal (Pa) and all values must specify the temperature (°C) and the frequency (rad/s) at which it has been measured since both G' and G' ' can change significantly with these two parameters.
  • the viscous behaviour of the adhesive can be interpreted to represent an indication of the ability of the adhesive to quickly attach and securely adhere.
  • the elastic behaviour can be interpreted as an indication of the "hardness" of the adhesive. Its value is also critical for good initial attachment. Their combination is believed to be an indicator of the required force upon removal.
  • the ratio between viscous and elastic and modulus is considered to be an indication of which fraction of the removal energy will be dissipated within the adhesive and which fraction is available to trigger the actual removal.
  • the dynamic behaviour of the elastic modulus at different frequencies representative of the conditions in which the adhesive respectively adheres/embeds dirt particles and retains them, is of key importance.
  • the ratio between the viscous modulus and the elastic modulus is important as well in order to further optimize the adhesive selection.
  • An adhesive to be used in the present invention has an elastic modulus G 25 at a temperature of 25°C and a viscous modulus G" 25 at a temperature of 25°C of wherein each of these values is measured at a specified frequency in rad/s.
  • the adhesive further has a dynamic elastic behaviour expressed in terms of elastic modulus percent increase ⁇ G' 25 which is defined in this case as the percent increase of G' 25 from a frequency of 0.1 rad/s to a frequency of 100 rad/s:
  • the adhesive also has a "crossover frequency" which is defined as the frequency in rad/s at which the value of G 25 is equal to G' ' 25 .

  • the adhesive to be used in the present invention also has a crossover frequency below 1000 rad/s, preferably below 700 rad/s most preferably below 500 rad/s.
  • the adhesives of the present invention are in the form of hot melt adhesives.
  • the adhesives will also preferably satisfy conditions such as sufficient cohesiveness (to prevent residue of adhesive on the treated surfaces) which are critical for commercial use of such adhesives and apparent to those skilled in the art.
  • hard surface cleaning articles comprising an adhesive as described above have an improved efficacy in trapping large particles and hairs.
  • adhesives work by two main mechanisms, i.e. 1) energetic interactions between the surface of the adhesive and the surface of the particle / substrate to be adhered (adherend) and 2) mechanical grafting or embedding by the adhesive of the particle / substrate to be adhered (adherend).
  • both mechanisms are possible the effectiveness of the adhesion achieves a maximum.
  • the adhesive is sufficiently soft -i.e. that its absolute value of G' is sufficiently low- at the typical frequencies at which the bond formation occurs, e.g. between 0.01 and 1 rad/s.
  • this can be interpreted as meaning that a high fraction of the energy applied for the debonding is dissipated within the adhesive (so it is not effective in causing the debonding) while this fact causes macroscopically the recording of a very high level of adhesive force.
  • compositions are expressed in wt% unless otherwise stated.
  • formulation criteria can be used in addition.
  • most compositions useful as adhesive have a substantially gel-like structure and are preferably gels.
  • Gels are materials wherein a three dimensional network caused by physical or chemical links formed between the molecules.
