Definitions
- Abrasive material accessories for a tool containing such abrasive material and method of manufacturing such abrasive material .
- the present invention concerns an abrasive material and accessories to a tool containing such abrasive material.
- abrasive materials are used to clean and/or polish floors, in particular stone floors, steel objects, wood surfaces and other elements.
- abrasive materials are often incorporated into a cleaning pad, sanding pad, polishing pad or briefly also called “pad”. These elements are indicated here as accessories to an instrument.
- the known abrasive materials contain interconnected but nonwoven fibres with resins and scattered abrasive particles within.
- An accessory to a tool containing such abrasive material always involves a three-dimensional element, often developed as a thin layer but always with a thickness.
- These three-dimensional elements are always provided with at least one sanding or polishing surface, here often called the horizontal surface.
- Horizontal originates from the orientation of these structures in a pad when placed on a horizontal surface.
- a nonwoven structure of the fibres results in layered cell structures, and in the above context these are also referred to as horizontal cell structures.
- the residues released during the cleaning or polishing process fill the pores of the material, with the adverse effect that these residues are deposited on the above- mentioned sanding or polishing surface, i.e. at the surface that makes contact with the surface to be sanded, polished or cleaned.
- sanding materials are made of paper, resin and sanding particles .
- WO 96/07509 describes an abrasive material based on a flatweave rug with loops, where the loops are fitted with abrasive particles.
- One variant also reveals a flatweave rug with short, straight hairs, which are equipped with abrasive particles.
- the present invention therefore aims to offer a solution to one or more of the aforementioned or possible other disadvantages .
- the abrasive material is therefore characterised by the fact that the wires are connected by a W-connection to the first (5) and an opposite second side (9) of the abrasive material.
- the after-treatment in question may be a heat treatment whereby the shape of the hairs is permanently changed by heating or a chemical treatment using chemicals that produce a similar effect.
- Such treatments are known from the fake fur industry.
- the after-treatment may also involve relaxation of the fibres from which the wire connection is made. This occurs, for example, when using a composite wire with multiple fibres of a rigid plastic such as nylon.
- the fibres in such a composite wire are subject to a torsion tension that is released when cutting such a composite wire so that the constituent fibres detach completely or partially and open up spatially similar to the umbel (umbella) inflorescence of a plant.
- the preparation from a cut double-layer fabric also ensures that the wires stand upright with respect to these sides.
- the abrasive particles mentioned are, for example, but not limited to, silicon carbide, diamond, cerium oxide, quartz, aluminium oxide or similar or a combination of two or more of the above.
- the application is carried out in a machine with the addition of the desired sanding particles. These abrasive particles are injected into the hairs in the correct consistency.
- the above-mentioned first side (5) is also called the abrasive material's abrasive surface.
- the change in the shape of the fibres also known as hairs, as a result of the aforementioned heat after-treatment or as a result of the relaxation of the torsion tension in the composite wires, contributes to the resilience of these fibres.
- the fibres will be able to exert a force on each other, whereby the fibres extend spatially in different directions, but without losing their predominantly upright orientation on the front of the sanding surface.
- the resilience and different orientation of the hairs will allow one hair or allow the other hair to penetrate, allowing an uneven surface to be cleaned, sanded or polished without loss of surface texture.
- the fibres extend in the upright space on the surface of the sanding surface in several directions and because some fibres are directed transversely (perpendicularly) on the surface to be cleaned or polished, also called the "vertical" hairs or fibres, they will be able to clean, polish or sand in depth.
- the orientation of the fibres in the upright space on the front of the sanding surface can be compared with the space occupied by the side axles in an umbel (umbella) inflorescence of a plant.
- the name 'vertical' therefore originates from the orientation of these hairs on the front of the sanding surface in a pad when laid on a horizontal surface.
- the hairs preferably have a curly shape, round spiral shape, angular spiral shape or zigzag shape. As a result of this design, these vertical hairs or fibres exhibit resilient properties or display the necessary flexibility .
- the length of the hair is between three millimetres and eighty millimetres.
- Such a long length of the hairs ensures that the abrasive material can clean even deeper, i.e. that a deeper effect of sanding, polishing or cleaning is obtained in the material. For example, it will be possible for the hairs to penetrate into wood grains and sand or clean them.
- connection of the double-layer fabric is made of heat-resistant material.
- the vertical hairs or fibres are preferably made from a heat- resistant plastic, which is heat-resistant up to 320°C with a melting point of 250°C under pressure, e.g. nylon 6,6, in order to allow the hairs to undergo the aforementioned after- treatment with heat or chemicals.
- a heat- resistant plastic which is heat-resistant up to 320°C with a melting point of 250°C under pressure, e.g. nylon 6,6, in order to allow the hairs to undergo the aforementioned after- treatment with heat or chemicals.
- Nylon 6,6 exists under different qualities, these are determined by the monomers and their repetitive unit that goes from 2000 to 3000 units, where 2000 stands for stiff and 3000 for flexible. This is important for compiling the basic tissue to obtain the correct end product for the various applications and application fields.
- the wires are multi-filament composite wires, also called Bulk Continuous Filament (BCF) wires. More specifically, BCF wires made of polyamide fibres such as nylon 6 and/or nylon 6,6. An example of such a BCF wire is described in detail in the European Patent EP3497272, which is included in its entirety as a reference.
- the wires are BCF wires composed of multiple nylon 6,6 fibres, more specifically 8 nylon 6,6 fibres.
- the method of preparation from a double-layer weave has an additional advantage. It allows the wires to be placed in a pattern on the sanding surface, as for example grouped in rows, hereinafter also called brush rows.
- connection of the double-layer tissue is such that after the mid-cutting of this tissue, the hairs are grouped in brush rows.
- the spaces between the brush rows are also called rills.
- the distance between the open rills is set according to the application.
- the pattern may vary depending on the application and may range from completely densely woven to any combination of openings or rills, i.e. areas where hairs are left out.
- the quantity of hairs per cm 2 and their combined length is also decisive in this claim and determines the application and application field.
- An advantage of this is that the particles or residues that come loose during the cleaning, polishing or sanding process can be removed via these rills when they are pushed out by the centrifugal force. They can then be sucked up by the machine .
- the hairs are provided with a binder to attach the abrasive particles to the hair.
- this binder is a resin, a resin compound, a phenol resin, a compound of phenol resin, a polyurethane, an adhesive, or the like, which may be natural or chemical, or a combination or compounds thereof.
- the aforementioned sanding particles are mixed together with a binder and sprayed onto the hairs under the correct consistency.
- the basic fabric can be produced in different ways.
- a double layer connected fabric which is cut in the middle with an additional boucle yarn as a weft yarn.
- This boucle yarn is used to form a kind of Velcro layer.
- the semi-finished product is dried with a whipped coating (shaving foam) under an infrared table so that the loop remains facing upwards to create the Velcro effect.
- the tuft method is used whereby, after tufting, a Velcro weave is laminated or burned against a second side of the abrasive material, also called the back.
- a layer of nonwoven, knitted textiles or the like (10) is applied a second side (9) of the abrasive material .
- Such a layer of nonwoven, knitted fabric or such is used to attach the abrasive material to a tool.
- the latter will contain a holder, also called a pad holder, to which the abrasive material can be attached.
- the shape of this pad holder will also influence the shape of the abrasive material, such as a disc shape for a disc-shaped pad holder, or a rectangular shape for attachment to a cylindrical pad holder, also called a roller brush.
- the pad holder will be disc-shaped, and will be fitted with hook-and-loop hooks on both sides, thus enabling a wraparound attachment of the abrasive material around the pad holder (See figures 7 and 8).
- the abrasive material's sanding or polishing surface may contain one or more cutouts. These cutouts are preferably configured to allow close connection of the abrasive material on the pad holder, for example in the form of flower cutouts.
- An additional advantage of such a layer of nonwoven, knitted textiles or the like (10) is that it also serves as a membrane to prevent the aforementioned binder from sinking to the bottom and to prevent the loops from losing their function for attachment with the Velcro hooks.
- the upright orientation of the hair is understood to mean that they orient spatially in line with the umbel (umbella) inflorescence of a plant. If we continue this analogy, we find that in this inflorescence, the side axles are mainly at an angle between 45° and 135° to the main axle or flower stem from which they depart. Also in the abrasive material according to this invention, the hairs will preferably be directed mainly at an angle between 45° and 135° with respect to the aforementioned first side or abrasive material sanding surface.
- the aforementioned part is preferably at least 15%, preferably at least 25% or at least 35% of the hair.
- the abrasive material can be applied in various ways.
- the invention also concerns an accessory to a tool containing an abrasive material according to the invention, where the accessory has a three-dimensional design and where the accessory concerns an abrasive brush pad, cleaning pad, sanding pad, polishing pad, roller brush or the like, which accessory is fitted with an abrasive or polishing surface as described herein.
- the aforementioned sanding or polishing surface is often referred to here as the horizontal surface .
- the accessories to a tool containing such abrasive material are an abrasive roller brush where the diameter is determined by the tube and not by the length of the bristles.
- the accessories of a tool containing such abrasive material are an abrasive sanding pad for cleaning floors, consisting of stone, plastic, wood, metal or other compositions.
- the accessories of a tool containing such abrasive material are an abrasive roller brush for cleaning floors, consisting of stone, plastic, wood, metal or other compositions.
- the accessories albeit an abrasive sanding pad or an abrasive roller brush, are used for sanding surfaces with the intention of removing material on stone, plastic, wood, metal or other compositions.
- the invention also involves a method for the manufacture of an abrasive material, which means that the method includes the following steps:
- A providing double-layer fabric with connection
- C treat the hairs so that the shape of the hairs is changed; D the application of abrasive particles to the hairs.
- connection can be a so-called W-connection .
- This method has the advantage that the abrasive material with the predominantly upright oriented hairs is manufactured according to the invention. As indicated above, this preparation method not only provides the aforementioned orientation, but also allows the wires to be placed in patterns on the sanding surface, including an orientation in brush rows with open rills, as well as in a variable density (number of wires per surface).
- Step C treatment may be heat treatment or chemical treatment with chemicals as mentioned above.
- the procedure after the above-mentioned step C includes the additional step of applying a layer of nonwoven or knitting, textile or similar on a second side of the abrasive material.
- This layer is that it can be used to attach the abrasive material, when incorporated in an accessory, to a tool by means of the Velcro principle.
- the procedure for the aforementioned step D includes the additional step of applying a binder to the hairs to attach the abrasive particles to the hairs.
- the sanding particles can adhere well to the hairs or fibres.
- the above-mentioned layer of nonwoven or knitting has the additional advantage that the binder, for example a resin or other adhesive, when it passes through the abrasive material, is held back by this layer of nonwoven or knitting.
- the procedure may include a further step E in which the abrasive material obtained after step D is thermally compressed.
- figure 1 schematically represents a cross-section of an abrasive material according to the invention
- figures 2 to 6 show the consecutive steps of the method according to the invention
- figure 7 shows an accessory according to the invention
- figure 8 shows an alternative of figure 7
- figure 9 schematically represents a cross-section of an abrasive material according to the invention
- Figure 1 schematically represents a cross-section of an abrasive material 1 according to the invention.
- connection 3 It comprises half of a double layer fabric 2 with connection 3 that is cut in the middle as shown in figure 2.
- this connection 3 is a so-called W-connection 3 through a first side 5 and opposite second side 9 of each layer from which the double layer fabric is constructed.
- connection 3 is therefore a wire 3 that is woven or stitched through both layers (top and bottom in figure 2) of the double layer fabric 2 and connected by a W-connection to the first (5) and an opposite second side (9) of the abrasive material.
- connection 3 of the double layer fabric 2, more specifically the wire 3 with which this connection 3 is made is in this case, but not necessarily, made of a heat- resistant material.
- the wire is a composite wire containing multiple hairs or fibres.
- hairs 4 or fibres 4 are formed on the first side 5 of the abrasive material 1.
- the fibres will open spatially after cutting as shown in Figure 9.
- the fibres 4 are preferably grouped in so-called brush rows 6.
- the open spaces 7 between these brush rows 6 are also called rills 7.
- the fibres 4 or hairs 4 thus created have been treated, resulting : permanent changes to their shape.
- the shape of the fibres 4 is a curl shape, but this can also be a round spiral shape, angular spiral shape, a zigzag shape or the like.
- the length L of these hairs 4 is in this case five millimetres, but this could also be ten, fifteen, thirty or, for example, fifty millimetres. Preferably the length L of the hairs 4 is between three millimetres and eighty millimetres .
- the hairs 4 have sanding particles 8.
- the hairs 4 have a binder to attach the sanding particles 8 to the hairs 4. This binder is not shown on the figures .
- At least part of the hairs 4 is directed mainly at an angle between 45° and 135° with respect to the aforementioned first side 5 of the abrasive material 1.
- This property can be obtained by the post-treatment of the hairs 4 or fibres 4, including the cutting of a composite thread, where the post-treatment also involves relaxation of the fibres from which the wire connection is made. This leads to the straightening of the hairs or fibres similar to the umbel inflorescence of a plant as shown, for example, in Figure 9.
- the aforementioned part is preferably at least 15%, or better at least 25% or at least 35% of the hairs 4 upright oriented on the front of the first side 5 or the abrasive material sanding surface.
- the second side 9 of the abrasive material 1 is in this case, but not necessary for the invention, provided with a layer nonwoven 10. This can also be a layer of textiles or the like.
- the method for manufacturing the abrasive material 1 is very simple and as follows.
- FIG. 2 to 6 show the successive steps.
- connection 3 is a W-connection 3, which can be derived from the stitching of the connection 3.
- connection 3 is made using a heat-resistant material.
- the connection of this double layer of tissue 2 is cut, as shown schematically in Figure 2.
- connection 3 is fixed. This can be done, for example, by stitching the tissue 2.
- Figure 4 shows the next step, in which the hairs 4 are treated so that the shape of the hairs 4 is changed.
- the shape of the hairs 4 is curly after treatment. This gives the hairs 4 a resilience.
- the above treatment can be thermal or chemical, with the hairs 4 permanently deformed.
- the wires 3 are made of a composite wire with multiple fibres of a rigid plastic such as nylon.
- the fibres in such a composite wire are subject to a torsion tension that is released when cutting such a composite wire so that the constituent fibres detach completely or partially and open up spatially similar to the umbel (umbella) inflorescence of a plant.
- This relaxation step replaces or forms part of the aforementioned thermal or chemical treatment and gives rise to a material as shown in Figure 9.
- the next step shown in Figure 5 is an optional additional step where a layer of nonwoven 10, but this may also be textile or similar, is applied to the second side 9 of the abrasive material 2. Then, in an optional step not shown in the figures, a binder is applied to the hairs 4. This binder will allow sanding particles 8 to attach to the hairs 4.
- the binder is a resin, for example.
- the nonwoven layer 10 from the previous step will stop the resin from coming through the abrasive material 1.
- Figure 6 shows the last step where the abrasive particles 8 are applied to the hairs 4.
- these abrasive particles 8 are diamond particles .
- the abrasive material 1 is manufactured and ready for use.
- Figure 7 shows an accessory 11 to a tool 12 containing an abrasive material 1 according to the invention.
- the accessory 11 has a three-dimensional design and in this case concerns a pad 11, for example a brushing, cleaning, sanding or polishing pad.
- the pad 11 has a disc shape and is covered with the abrasive material 1.
- the pad 11 is equipped with, for example, Velcro hooks which can attach to the nonwoven 10 on the second side 9 of the abrasive material 1, so that the abrasive material 1 can attach to the pad 11.
- the pad 11 has a sanding or polishing surface 13.
- the tool 12 on which the pad 11 is applied will allow the pad 11 to rotate at high speed.
- the tool 12 can then be placed on a surface to be sanded, brushed, cleaned or polished.
- the resilient hairs 4 will be able to sand, brush, clean or polish in the depth of the surface.
- the particles thus removed from the surface will be removed via the rills 7 and will not accumulate between the surface and the polishing surface 13 of the pad 11.
- Figure 8 shows a variant of an accessory 11 according to figure 7, in which case the shape of the pad 11 is changed.
- the present invention is by no means limited to the embodiments described as examples and shown in the figures, but an abrasive material according to the invention, an accessory to an instrument containing such abrasive material and the method of manufacturing such abrasive material can be achieved according to different variants without acting outside the scope of the invention.
- a characteristic of the abrasive according to the invention has to do with the upright orientation of the hairs, and in particular an orientation similar to the umbel (umbella) inflorescence of a plant.
- the shape, structure, and upright orientation of the bristles provide the necessary resilience, which we can also call brush power, as we zoom more closely into function and resilience, we see that because of the spatial orientation of the fibre ends, the strength is not only developed on the upper surface, but also in lower sections of the ecoforce, this in contrast to the classic sanding brushes and nonwoven open cell structures that generate these forces only at the front, at the highest points of their surface.
- the tests also showed that the resilience ensures that the structure of a surface is not affected and only the dirt is detached, unlike the other materials tested.
- the tests have also shown that the length and resilience of the hairs ensures that sanding is not possible or only to a limited extent, even with coarse grains, (data not shown). To achieve an abrasive effect, the fibres must be shortened.
- the Ecoforce pad thus overlaps the current operation of the nonwovens and the brush pads and has unique properties with completely different end results without damaging the surface.
