Definitions

  • the invention has been conceived and developed in the field of maintenance, specifically housekeeping, with reference to technical problem of effective removal of limestone, deposited in weak thickness on the surfaces, without alteration (of the stripes type) of said surfaces.
  • the surfaces in question are in particular the steel surfaces stainless, acrylic polymers, chrome, glass, tiles ...
  • the first of these handsets - "Fra ⁇ cheur marine” - associates with a cellulosic alveolar support (a sponge) a non-woven, carded, needled, reinforced with a cross-linked latex (not loaded with mineral fillers scouring and / or abrasive).
  • Said nonwoven has an airy structure based on large reinforced fibers.
  • the second of these handsets - "Salsa” - combines with a support cellulosic alveolar (a sponge) a non-woven, carded, needled, bonded, loosely, with a latex and covered with an expanded superficial layer. Said layer is deposited by screen printing. Neither said layer nor said latex does not contain mineral charges.
  • More aggressive maintenance tools usually include nonwovens, carded, needled, on which, successively, sprayed an abrasive formulation (a charged formophenolic resin in abrasive mineral fillers which is crosslinked in situ) then deposited by impregnation a latex (which is also crosslinked in situ). Said nonwovens are secured to a cellulosic alveolar support (a sponge) and base their action on that of the mineral fillers of the formulation, mineral fillers whose equivalent diameter is included between 40 and 60 microns. In use, these tools scratch strongly and irreversibly surfaces, especially stainless steel, in chromium or acrylic polymers.
  • Chemicals are more delicate manipulation. They are necessarily used with a support tool, for example a cloth or a sponge, a support tool that is inevitably attacked by the chemical used.
  • the invention proposes an interesting alternative to these tools of the prior art, alternative that ensures good cleaning properties limestone without altering the cleaned surfaces and without having to resort to chemical products.
  • Said alternative is based on a nonwoven concept with a loaded formulation, of a new type.
  • the present invention therefore relates to new nonwovens with filled formulation. It's more precisely of nonwovens whose basic structure has two faces substantially parallel ones, at least one of said two faces (one of said two faces or both faces), on at least a part of its surface (on all or only part of its surface) advantageously over its entire surface, being covered with a formulation scouring.
  • the basic structure of said nonwovens does not present any original features. It is obtained, conventionally, by carding, topping and generally needling of its constituent fibers.
  • the recurring formulation inevitably intervenes on the surface (on one of its two main faces or on both its main faces) but is also likely to intervene in its volume.
  • said recurring formulation is base of a flexible binder that contains an effective amount of fillers fine minerals; said mineral fillers having a diameter equivalent less than or equal to 20 ⁇ m.
  • Said recurring formulation is original in that it combines, in its structure, flexible binder and charges fines.
  • the binder is flexible, it is not hard. It is thus non-brittle, no susceptible to cracking and therefore, to the use of the non-woven on surfaces, not fragile, not likely to scratch said surfaces (by itself and / or by the liberated charges, at the end of his cracking).
  • a resin thermoset obtained from a thermosetting resin (for example example of phenolic type, epoxy or melamine).
  • said binder flexible is likely to be obtained from a latex, presenting a glass transition temperature (Tg) less than 20 ° C. Said latex is heat treated. The heat treatment in question ensures at least drying and advantageously crosslinking.
  • the flexible binder of the The recurring formulation of the invention therefore advantageously consists of a crosslinked latex, obtainable by heat treatment of a crosslinkable latex whose glass transition temperature is less than 20 ° C.
  • Such latices are known to those skilled in the art.
  • the mineral fillers present in the scouring formulation of the invention are considerably smaller than those usually present in the structure of housekeeping tools of the prior art, in particular those called “more aggressive", described in the introduction. of this text. There is generally a ratio of at least 2 between the size of their equivalent diameters.
  • the mineral fillers present all have an equivalent diameter less than or equal to 20 ⁇ m and at least half (in number) of them have an equivalent diameter less than or equal to 10 ⁇ m (has a D50 of 10 ⁇ m ).
  • said mineral fillers present all have an equivalent diameter less than or equal to 20 ⁇ m and at least half (in number) of them have an equivalent diameter less than or equal to 5 ⁇ m (has a D50 of 5 ⁇ m).
  • Nonwovens of the invention very effective with reference to the technical problem mentioned in the introduction of this text, have their recurring formulation which contains small and smaller mineral fillers; none of said mineral fillers has an equivalent diameter greater than 20 microns and at least half of them has an equivalent diameter less than or equal to 3 microns.
  • the nonwovens of the invention are coated with scouring formulations that are scoured by the presence of small mineral particles, advantageously very small mineral particles. Said small and / or very small particles have been found, quite surprisingly, effective and low scratching power.
  • the mineral charges involved are obviously present in an effective, perfectly determinable and optimizable by the skilled person. There should be enough said loads so that their scouring action is likely to express yourself but not too much because then the wording is likely to crumble, lose its cohesion.
  • the binder used must be able to binder function without annihilating the action of mineral particles ...
  • the flexible binder is thus advantageously loaded at a charge rate ( ⁇ ) defined below:
  • VPC Volumic Particle Concentration
  • CPVC Critical Volume Particle Concentration
  • VPC Volumic Particle Concentration
  • the parameter ⁇ defined above is greater than 0.3, preferably greater than 0.8. It is expected that this parameter can have a value greater than 1; we then observe the presence of emerging particles of the binder ...
  • the mineral fillers present in the form of small and / or very small particles, may especially consist of particles of alumina (Al 2 O 3 ), silica (SiO 2 ), calcium carbonate (CaCO 3 ), feldspar (potassium, sodium and / or calcium aluminosilicate), talc (magnesium silicate) or mixtures of such particles. This list is not exhaustive.
  • the recurrent formulation described above contains, in addition to fine mineral fillers, other charges and in particular synthetic (organic) fillers with decreasing power soft.
  • Such charges may in particular consist of particles in polyethylene terephthalate (PET), polymethylmethacrylate (PMMA), polyurethane (PU), polystyrene (PS) ...
  • Said recurring formulation can also be loaded with dyes, microcapsules to release perfumes, disinfectant type active agents ... Si necessary, these other charges are to be considered in the calculation of the rate of loads ( ⁇ ) indicated above.
  • the concept of the invention is based on the combination of a torque binder and fine mineral (scouring) fillers in a formulation able to make particularly effective, as household maintenance tool, a nonwoven covered with said formulation.
  • the nonwovens in question generally have a basis weight of between 60 and 600 g / m 2 , more generally between 150 and 450 g / m 2 .
  • a structure too light, too airy, is not really suitable for the purposes of the invention, a too heavy structure is too expensive.
  • the recurrent formulations of the invention advantageously intervene on relatively heavy structures.
  • the recurring formulation in question generally covers from 150 to 500 g / m 2 , the surface on which it is present. We have seen that said surface could represent 100% or less of a face, that said surface could develop on both sides.
  • the recurring formulation according to the invention (flexible binder + fine mineral fillers) is present, at least in part, on reliefs of the nonwoven surface.
  • the action of the charges present on said reliefs is thus reinforced.
  • On one side of a non-woven of the invention one can thus have reliefs and the formulation scouring covering all of said face or only the vertices of said landforms.
  • the nonwovens of the invention are able to constitute in themselves powerful maintenance tools or to enter into the composite structure of high performance maintenance tools, composite structure.
  • Such one-component maintenance tools consisting of such a nonwoven
  • composite structure including least one such nonwoven
  • one solidarises advantageously at least one nonwoven of the invention to a substrate.
  • said substrate may in particular be chosen from synthetic sponges, especially polyurethane (PU) and cellulosic sponges.
  • said substrate can thus be sandwiched between two nonwovens of the invention, secured to its two main faces; said substrate is generally secured to a single nonwoven of the invention, on one of its main faces.
  • the structure composite of a maintenance tool of the invention comprises a nonwoven of the invention which is covered with the recurring formulation on a single of its two main faces (covered in whole or in part only) and which is secured to a substrate by the other of its two main faces (not covered with recurring formulation).
  • the first step of developing a nonwoven, structure of base is classic. It is generally implemented by carding and topping the constituent fibers of said nonwoven.
  • the tablecloth obtained is advantageously needled, to be consolidated.
  • the third step of the process consists of a treatment thermal of the composition on (on and more or less in) the nonwoven, generally in heat treatment of said nonwoven covered with said composition.
  • the recurrent formulation of the invention results of the heat treatment of the precursor composition which, in fact, contains the fixed mineral charges in a precursor of the binder.
  • This heat treatment is likely to physically alter and / or chemically said precursor composition, more particularly said precursor of the binder (modification which transforms it into a binder).
  • This treatment thermal process is actually used to remove the solvent contained in said composition (in said precursor of the binder) and / or to modify chemically said composition (said precursor of the binder).
  • Precursor binder can thus be dried and / or crosslinked.
  • the flexible binder of the formulation scouring nonwovens of the invention can be obtained from a latex having a glass transition temperature (Tg) of less than 20 ° C, advantageously such a crosslinkable latex.
  • Tg glass transition temperature
  • Such a crosslinkable latex is treated thermally to be dried and crosslinked.
  • the mineral fillers involved are as described above (for example: Al 2 O 3 , SiO 2 , CaCO 3, etc.) and are advantageously used at levels such that the formulations obtained from said compositions exhibit a charge rate ( ⁇ ) as defined above.
  • the process of the invention which comprises the three stages successive stages specified above may include a fourth step implemented on the nonwoven manufactured before intervention of the recurring composition.
  • Advantageously modifies at least a part of the surface intended to receive the precursor composition of the recurrent formulation to create reliefs.
  • recurrent formulation positioned on said reliefs, gains in efficiency.
  • the creation of reliefs on the surface of a non-woven hardly poses problem to the skilled person. Such reliefs are generally obtained by thermogaufrage. Techniques can also be used with ultrasound or specific needling techniques. In this last hypothesis, we can include this fourth stage of the process in the first one, at the end of which a nonwoven is directly generated needled with reliefs ...
  • the parentheses indicate an advantageous variant according to which the recurring formulation intervenes on only one of the two faces of the non-woven, and the joining is done by the other side principal of said nonwoven. It is thus possible to secure a nonwoven to such substrate, two nonwovens with opposite main faces of such a substrate (then sandwiched) ...
  • Bonding - nonwoven / substrate - can be implemented by any known method and in particular by gluing, flaming, sewing.
  • the invention is illustrated in its various aspects of products and method, by the following example.
  • a recurring nonwoven of the invention then a maintenance tool of the invention.
  • a needle-punched nonwoven web having a basis weight of 400 g / m 2 was first obtained, conventionally, by carding / topping / needling. It consists of 75% by weight of polyester fibers (7 dtex / 60 mm) and 25% by weight of viscose fibers (3.3 dtex / 60 mm).
  • Said sheet has been thermogaufrée on one of its two main faces so that patterns "S" have been generated on the surface of said face. It was in fact circulated between an embossed cylinder (which has said recessed patterns) and a back-pressure cylinder, at 145 ° C., with application of a pressure of 10 6 Pa.
  • Texpol AS 99T it is a crosslinkable acrylic latex with a Tg of -7 ° C. This product is marketed by Eurotext.
  • CAHP F 1200 these are particles of alumina (Al 2 O 3 ). All these particles have an equivalent diameter less than or equal to 20 microns and 50% of them (half) have an equivalent diameter less than or equal to 3 microns.
  • Glymo it is a wetting agent marketed by the company Degussa Huls.
  • Neon yellow and orange Sagunto these are dyes (Amarilo Fluorescent 10 G extra conc and Anaranjado Fluorescent 2G extra conc., Respectively) marketed by the company Minerva Color.
  • Clear LA2 it is a regulator of vicosity, marketed by the Emequinica Company.
  • the non-woven, coated on one of its two main faces said composition was then heat-treated in an oven. He was maintained from 160 ° C to 180 ° C for 10 min. This heat treatment has ensured the drying and crosslinking of the acrylic latex.
  • the scouring nonwoven of the invention thus obtained was laminated on a sponge, by its main face not thermogaufrée, no covered with the recurring formulation.
  • the resulting handset was tested under the specified conditions below, as regards its anti-limescale efficiency (its ability to clean the limestone) and as regards its respect for surfaces (its ability not to scratch). Under the same conditions, we tested the handsets of art “Fra ⁇ cheur marine” and “Salsa” (see the introduction to this text).
  • Cleaning is implemented with the tested handset hooked to a sample holder by its side sponge and animated, with application of the pressure indicated above, of determined movements.
  • the ordinate corresponds to the number of Martindale® laps needed to remove limescale. Obviously, the higher the number of laps is weak, the more effective the tool is.
  • the handset of the invention in both contexts of "deposit low “and” strong deposit ", is far more effective than both prior art handsets.
  • the tool of the invention combines efficiency and weak scratching power.
