Description

Technical Field

[0001] The present invention relates to an abrasive material, and accessories for tools including such abrasive materials.

Background Art

[0002] Abrasives are known to be used for cleaning and / or polishing floors, particularly stone floors, steel objects, wood surfaces and other elements. These abrasives are often incorporated into cleaning pads, sanding pads, polishing pads, or are simply referred to here as "pads". These elements are shown here as accessories for equipment.

[0003] Known abrasives include non-woven fibers that are interconnected and have resin and abrasive particles dispersed therein. Most of these known materials are produced using a felting method. Here, the fibers are hooked together or joined at various intersections. This always results in a layered cell structure.

[0004] Accessories for tools including such abrasives often unfold as thin layers but always include three-dimensional elements that usually have a thickness. These three-dimensional elements always have at least one sanding or polishing surface (often referred to here as a horizontal surface). Horizontal is derived from the orientation of these structures within the pad when placed on a horizontal plane.

[0005] As described above, the nonwoven structure of the fibers results in a layered cell structure, which in the context of the above is also called a horizontal cell structure. A drawback of these known abrasives is that they are easily blocked or clogged. Residues released during the cleaning or polishing process fill (or clog) the pores of the material, and these residues have the adverse effect of accumulating on the sanding or polishing surface, i.e., the surface that comes into contact with the surface being sanded, polished, or cleaned. Sometimes, residues accumulate on the surface, resulting in an uneven surface. This occurs, for example, when polishing plaster plates.

[0006] Other sanding materials are made of paper, resin, and sanding particles. International Publication No. 96 / 07509 describes an abrasive based on a flatweave rug with loops, to which abrasive particles are attached. Another variation discloses a flat rug (also called a woven fabric) with short, straight fibers and abrasive particles. [Prior art documents] [Patent Documents]

[0007] [Patent Document 1] International Publication No. 96 / 07509 pamphlet [Overview of the project] [Problems that the invention aims to solve]

[0008] The present invention aims to provide a solution to one or more of the aforementioned or possible other drawbacks. [Means for solving the problem]

[0009] The present invention relates to an abrasive material comprising a double-layered cloth having threaded connections cut in the center to form bristles (hereinafter, all plural) or fibers (hereinafter, all plural) on the first side of the abrasive material, wherein the bristles (hereinafter, the term "fiber" is also used to encompass the meaning of "bristles" and "fibers" are synonymous) are post-treated so that the shape of the bristles is permanently changed, and the bristles are equipped with abrasive particles.

[0010] A characteristic of the double-layered fabric (tissue: thin woven fabric) is that the wires 3 forming the joints within the double-layered fabric are bonded to the layers of the double-layered fabric by W-bonds, as will be further described herein. Therefore, the abrasive is characterized in that the wires are bonded to the first side (5) and the opposite second side (9) of the abrasive by W-bonds.

[0011] The post-treatment may be a heat treatment that permanently alters the shape of the fur by heating or chemical treatment using a chemical substance that produces a similar effect. Such treatments are known in the field of artificial fur industry technology.

[0012] Post-processing may also include loosening (slackening) of the fibers in which the wire bond is formed. This occurs, for example, when using a composite wire having multiple fibers of a rigid plastic such as nylon. The fibers in such a composite wire are subjected to torsional tension that is released when such a composite wire is cut, and as a result the constituent fibers detach completely or partially, opening up in a spatially similar manner to the inflorescence of the plant umbella.

[0013] In addition to the aforementioned W-shape (W-bond) for bonding the wire to both sides of the abrasive, preparation from a cut double-layer cloth achieves that the wire stands upright against these two sides. This results in a configuration that is distinctly different from the aforementioned layered cell structure obtained based on the felting method. As will be described in more detail, this vertical orientation of the wire results in a different function of the abrasive obtained using the method described herein.

[0014] The abrasive particles used in this invention are, for example, but are not limited to, silicon carbide, diamond, cerium oxide, quartz, aluminum oxide, or the same, or a combination of two or more of the above. This process is carried out in a machine into which the desired abrasive particles have been added. These abrasive particles are injected into the bristles with precise consistency.

[0015] The first side portion (5) described above is also called the abrasive surface of the abrasive material.

[0016] As a result of the aforementioned heat-post-treatment, or as a result of the loosening of torsional tension in the composite wire, the change in the shape of the fibers, also known as bristles, contributes to the elasticity of these fibers. This means that the fibers have a certain elasticity. As a result, the fibers can exert force on each other, thereby stretching spatially in different directions, but they do not lose their predominantly upright orientation on the front surface of the polished surface.

[0017] During surface cleaning, sanding, or polishing, the elasticity and different orientations of the bristles allow one bristle or another to penetrate, enabling the cleaning, sanding, or polishing of uneven surfaces without losing surface texture.

[0018] In other words, the fibers extend in several directions within the upright space on the surface of the abrasive, and some fibers are oriented transversely (perpendicularly) on the surface being cleaned or polished, also called "vertical" bristles or fibers, so that they can clean, sand, or polish deeply. As described above, the orientation of the fibers in the upright space on the front of the abrasive can be compared to the space occupied by the lateral axis in the inflorescence of the plant Amber (Ficus umbellata).

[0019] Therefore, the term "vertical" derives from the orientation of these bristles on the front surface of the abrasive surface within the pad when it is placed on a horizontal surface.

[0020] The hairs preferably have a curled shape, a round spiral shape, an angular spiral shape, or a zigzag shape. As a result of this design, these vertical hairs or fibers exhibit elasticity or the required flexibility. Preferably, the length of the hairs is from 3 millimeters to 80 millimeters. Such long hairs ensure that the abrasive can clean deeper, that is, a deeper effect of sanding, polishing, or cleaning can be obtained in the target material. For example, it is possible for the hairs to penetrate into the grain and sand or to clean them.

[0021] It should be noted that the elastic properties of the hairs are essential for achieving good functionality. Preferably, the joint of the double-layer fabric is made of a heat-resistant material. This means that the aforementioned fibers or hairs are made of this heat-resistant material. <>

[0022] The vertical hairs or fibers are preferably made of a heat-resistant plastic, which is heat-resistant up to 320 °C under pressure and has a melting point of 250 °C, for example, nylon 6,6, and enables the hairs to undergo the aforementioned post-treatment by heat or chemicals.

[0023] Nylon 6,6 exists in different quality states, which are determined by the monomers and their repeating units and range from 2000 to 3000 units (2000 represents rigidity and 3000 represents flexibility). This is important for compiling the basic tissue to obtain the correct end product for various uses and application fields. In a preferred form, the wire is a multifilament composite wire, also called a bulk continuous filament (BCF) wire. More specifically, the BCF wire is made from polyamide fibers such as nylon 6 and / or nylon 6,6. Examples of such BCF wires are described in detail in European Patent EP3497272, which is hereby incorporated by reference in its entirety into the present invention. In a preferred form, the wire is a BCF wire composed of a plurality of nylon 6,6 fibers, more specifically, 8 nylon 6,6 fibers.

[0024] In addition to the above-described features regarding the method of bonding and orienting the wire, the method of preparation from a double-layer weave (also called a cloth) has further advantages. It allows the wire to be arranged in a pattern on the polishing surface such that the wire is assembled into a plurality of rows, also called brush rows below, for example.

[0025] Preferably, the bonding of the double-layer tissue is such that after an intermediate cut (cut) of the tissue, the hairs are grouped into brush rows.

[0026] The space between the brush rows is also called rills. The distance between the open rills is set according to the application.

[0027] The pattern may vary according to the application and may range from a completely densely woven one to any combination of openings or rills, i.e., areas where the hairs are left out. cm 2 The amount of hairs per hit and their combined length are also important in this requirement and determine the application and application field.

[0028] The advantage of this is that loose particles or residues during the cleaning, polishing, or sanding process can be removed through these drills as they are pushed out by centrifugal force. They can then be sucked up by a machine.

[0029] In other words, these particles do not accumulate between the cleaned, polished, or sanded surface and the abrasive material.

[0030] Preferably, the bristles are coated with a binder to adhere the abrasive particles to them. For example, this binder may be a resin, a resin compound, a phenolic resin, a phenolic resin compound, polyurethane, an adhesive, etc., and these may be natural, chemical, a combination thereof, or a compound thereof. In a so-called spraying machine, the abrasive particles are mixed with the binder and sprayed onto the bristles under the correct consistency.

[0031] Basic fabric can be manufactured in various ways. For example, a double-layered bonded fabric has an additional boucle yarn as the weft and is cut in the middle. This boucle yarn is a type of Velcro. 登録商標 It is used to form a layer (Velcro layer). After the weaving process, the semi-finished product is dried with a whipped coating (shaving foam) under an infrared table, and as a result the loops remain facing upwards, and the Velcro is formed. 登録商標 To create an effect (Velcro effect).

[0032] Alternatively, the tuft method is used, and after tufting, Velcro is applied. 登録商標 A velcro weave is laminated or fired onto the second side of the abrasive material, also known as the reverse side.

[0033] In another embodiment, a layer (10) such as a nonwoven fabric or knitted fabric is set on the second side (9) of the abrasive material.

[0034] Such layers of nonwoven or knitted fabrics are used to attach abrasives to tools. For this purpose, the latter includes a holder, also called a pad holder, to which the abrasive can be attached. The shape of this pad holder also affects the shape of the abrasive, such as a disc shape for disc-shaped pad holders, or a rectangular shape for attachment to cylindrical pad holders, also called roller brushes. In a special embodiment, the pad holder is disc-shaped and has hook-and-loop fasteners on both sides, so that abrasive material can be wrapped around the pad holder (see Figures 7 and 8). With such a wrapped pad holder, there is a better range of abrasive material at the corners and edges of the object / surface to be processed. For packaging the pad holder, the sanding or polishing surface of the abrasive material may include one or more notches. These notches are preferably configured, for example, in the form of flower notches, to allow for close bonding of the abrasive material on the pad holder.

[0035] A further advantage of such a layer (10) of nonwoven fabric, knitted fabric, etc. is that it prevents the aforementioned binder from sinking to the bottom, and the loops are Velcro. 登録商標 It also functions as a membrane to prevent it from losing its ability to attach to the hook.

[0036] As described above, the erect orientation of the hairs is understood to mean that the hairs have an orientation that spatially coincides with the ambellaceous inflorescence of plants. Continuing this analogy, it can be seen that in this inflorescence, the lateral axes are mainly at an angle of 45° to 135° with respect to the main axis or flower stalk from which they originate. Furthermore, in the abrasive material according to the present invention, the hairs are preferably oriented at an angle of mainly 45° to 135° with respect to the aforementioned first lateral portion or abrasive surface. This portion preferably accounts for at least 15%, preferably at least 25%, or at least 35% of the hairs.

[0037] Abrasives can be used in a variety of ways.

[0038] The present invention also relates to tool accessories containing abrasives according to the present invention, wherein the accessories have a three-dimensional structure and relate to polishing brush pads, cleaning pads, sanding pads, polishing pads, roller brushes, etc., to which the abrasives or polishing surfaces described herein are attached.

[0039] With respect to the components of the abrasive material according to the present invention, the aforementioned sanding or polishing surface is often referred to here as a horizontal surface.

[0040] According to a preferred embodiment, the accessory of such a tool containing an abrasive material is an abrasive roller brush whose diameter, rather than the length of the bristles, is determined by the tube.

[0041] According to a preferred embodiment, an accessory for a tool containing such an abrasive is an abrasive sanding pad for cleaning floors, made of stone, plastic, wood, metal, or other composition.

[0042] According to a preferred embodiment, an accessory for a tool containing such an abrasive material is an abrasive roller brush for cleaning floors, made of stone, plastic, wood, metal, or other composition.

[0043] Alternatively, accessories such as abrasive sanding pads or abrasive roller brushes are used to polish surfaces for the purpose of removing material from stone, plastic, wood, metal, or other compositions.

[0044] The present invention also relates to a method for manufacturing an abrasive, the method comprising the following steps: A: To provide a double-layered fabric having a connection; B: A step of cutting the joint of the double-layered cloth to form hairs or fibers (the term "hairs" also means "fibers") on the first side of the abrasive material; C: To process hairs in a way that changes their shape; D: Application of abrasive particles to the hair. For example, the aforementioned bond can be a so-called W bond.

[0045] This method has the advantage that abrasives having primarily upright-oriented bristles are manufactured according to the present invention. As described above, this preparation method not only provides the orientation described above, but also makes it possible to pattern the wires on a sanding surface, including orientation in a brush row with open rills, as well as variable density (number of wires per surface).

[0046] As described above, the treatment in step C may be heat treatment or chemical treatment with chemicals.

[0047] Preferably, the procedure following step C described above includes the additional step of applying a layer of nonwoven or knitted fabric, woven fabric or similar material to the second side of the abrasive. The advantage of this layer is that when incorporated into the accessory, the abrasive is secured with Velcro. 登録商標 (Velcro) principle (Velcro) 登録商標 It can be used to attach to a tool by means of a type of [unclear].

[0048] Preferably, the procedure for step D described above includes an additional step of applying a binder to the hair in order to adhere the abrasive particles to the hair. With the help of this binder, the abrasive particles can adhere well to the hair or fibers. In this case, the layer of nonwoven or knitted fabric described above has the additional advantage that the binder, such as a resin or other adhesive, is held by this layer of nonwoven or knitted fabric as it passes through the abrasive material.

[0049] In further embodiments, this procedure may include a further step E of thermally compressing the abrasive obtained after step D. By thermally compressing the material, the wire is shortened, and the material gains more sanding power without losing the aforementioned advantages associated with the upright orientation of the wire. [Brief explanation of the drawing]

[0050] With insights to better demonstrate the features of the present invention, several preferred examples of abrasives according to the present invention, accessories for instruments containing such abrasives, and methods for manufacturing such abrasives are described herein with reference to the accompanying drawings: [Figure 1] Figure 1 schematically shows a cross-section of the abrasive material according to the present invention, and Figures 2-6 show the sequential steps of the method according to the present invention; [Figure 2] Same as above [Figure 3] Same as above [Figure 4] Same as above [Figure 5] Same as above [Figure 6] Same as above [Figure 7] Figure 7 shows an accessory according to the present invention, and Figure 8 shows an alternative to Figure 7; [Figure 8] Same as above [Figure 9] Figure 9 schematically shows a cross-section of the abrasive material according to the present invention. [Explanation of symbols]

[0051] 1: Abrasive material 2: Double-layered thin fabric 2:Double layer cloth 2: Thin fabric (tissue) 3:W bond 3: Threaded joint 3: Wire 3:Joining part 4: Fibers 4: Hair 5: First side 6: Brush row 7: Rill (narrow groove) 7:Open space 8:Sanding particles 9: Second side 10: Nonwoven fabric 10: Non-woven layer 11: Accessories 11: Pad 12:Tools 12: Tools 13: Sanded or polished surface 13: Polished surface [Modes for carrying out the invention]

[0052] Figure 1 schematically shows a cross-section of the abrasive material 1 according to the present invention. It comprises half of a double-layered cloth 2 having a joint 3 cut in the middle as shown in Figure 2. In the illustrated embodiment, this joint 3 is a so-called W-joint 3 that passes through the first side 5 and the opposite second side 9 of each layer constituting the double-layered cloth (reference numeral 3 has meanings such as joint, joint, W-joint, wire, suture joint, etc.).

[0053] Therefore, the connecting portion 3 is a wire 3 that is woven or sewn through both layers of the double-layered fabric 2 (upper and lower sides in Figure 2) and connected to the first side 5 and the opposite second side 9 of the abrasive material by a W-joint.

[0054] In this case, the joint 3 of the double-layered fabric 2, more specifically the wire 3 on which this joint 3 is formed, is made of a heat-resistant material, although this is not essential. In a preferred embodiment, the wire is a composite wire containing multiple hairs or fibers.

[0055] By cutting this joint 3, the hairs 4 or fibers 4 are formed on the first side portion 5 of the abrasive material 1. In this embodiment in which a wire is formed, as shown in Figure 9, the fibers open up spatially after cutting.

[0056] The fibers 4 are preferably grouped into so-called brush rows 6. The open spaces 7 between these brush rows 6 are also called rills 7.

[0057] The fibers 4 or hairs 4 produced in this manner are processed, resulting in a permanent change in their shape. In this case, the shape of the fibers 4 is curly, but it may also be a round spiral, a square spiral, a zigzag, etc.

[0058] The length L of these hairs 4 is 5 millimeters in this case, but it may be 10 millimeters, 15 millimeters, 30 millimeters, or, for example, 50 millimeters. Preferably, the length L of the hairs 4 is between 3 millimeters and 80 millimeters.

[0059] According to the present invention, the bristles 4 have sanding particles 8. In this case, the bristles 4 have a binder for attaching the sanding particles 8 to the bristles 4. This binder is not shown in the figure.

[0060] In Figure 1, all the bristles 4 are shown perpendicular to the first side 5 of the abrasive material 1, but it should be noted that this is only a schematic representation. As mentioned above, this upright orientation of the bristles means that they spatially aggregate along the ambellate (or ambellaceous) inflorescence of the plant, for example, as shown in Figure 9.

[0061] In practice, not all of the bristles 4 are oriented perpendicular to the first side portion 5. Preferably, at least some of the bristles 4 are oriented at an angle of 45° to 135° to the aforementioned first side portion 5 of the abrasive material 1.

[0062] This property can be obtained by post-treatment of the hairs 4 or fibers 4, which includes cutting the composite yarn, and post-treatment also includes loosening the fibers to create wire bonds. This results in straightening of the hairs or fibers, similar to the ambell inflorescence of plants, as shown, for example, in Figure 9.

[0063] Such portions preferably comprise at least 15%, or better at least 25%, or at least 35%, of the bristles 4 directed toward the first side portion 5 or the front surface of the abrasive material.

[0064] In this case, the second side portion 9 of the abrasive material 1 is provided with a nonwoven fabric layer 10, but this is not essential in the present invention. This may be a layer of woven fabric or the like.

[0065] The method for manufacturing the abrasive 1 is very simple and is as follows. Figures 2 to 6 show the sequential steps. Starting with a double-layered cloth 2 having a joint 3, this joint is a W joint 3, which can be obtained by stitching the joint 3. In this case, the joint 3 is made using a heat-resistant material, as already mentioned.

[0066] As schematically shown in Figure 2, the bond between the two layers of fabric 2 is broken. This causes hair 4 to form on the first side portion 5.

[0067] In the next possible step, the joint 3 is secured, as shown in Figure 3. This can be done, for example, by sewing the fabric 2 together.

[0068] Figure 4 shows the next step in which the hair 4 is treated so that its shape is changed. The shape of the hair 4 is curled after treatment. This gives the hair 4 elasticity. The above treatment can be thermal or chemical, and the hair 4 is permanently deformed.

[0069] In another embodiment, wire 3 is made from a composite wire having multiple fibers of a rigid plastic such as nylon. The fibers in such a composite wire are subjected to torsional tension that is released when such a composite wire is cut, and as a result the constituent fibers detach completely or partially, opening up spatially similar to the inflorescence of the plant umbellata. This loosening step replaces or forms the aforementioned heat or chemical treatment part, resulting in something like the one shown in Figure 9.

[0070] The next step shown in Figure 5 is an optional additional step in which a nonwoven fabric layer 10, which may be woven fabric or similar, is applied (installed) on the second side 9 of the abrasive material.

[0071] Next, in an optional step not shown, a binder is applied to the bristles 4. This binder allows the abrasive particles 8 to adhere to the bristles 4. The binder is, for example, a resin.

[0072] The nonwoven fabric layer 10 from the previous step prevents the resin from passing through the abrasive material 1. Figure 6 shows the final step in which the abrasive particles 8 are applied to the hair 4. For example, these abrasive particles 8 are diamond particles. In this way, the abrasive material 1 is manufactured and ready for actual use.

[0073] Possible practical applications of the abrasive material 1 are shown in Figures 7 and 8. Figure 7 shows an accessory 11 for a tool 12 containing the abrasive material 1 according to the present invention. The accessory 11 has a three-dimensional shape, in which case a pad 11, for example, a brushing, cleaning, sanding, or polishing pad is exemplified. The pad 11 is disc-shaped and covered with the abrasive material 1.

[0074] For this practical use, the pad 11 can be attached, for example, to the nonwoven fabric 10 on the second side 9 of the abrasive material 1 using Velcro. 登録商標Equipped with Velcro hooks, the abrasive material 1 can be attached to the pad 11. By attaching the abrasive material 1, the pad 11 has a polishing surface 13. The tool 12 to which the pad 11 is applied allows the pad 11 to rotate at high speed. The tool 12 can then be applied (e.g., placed) on the surface to be sanded, brushed, cleaned, or polished. The resilient bristles 4 can sand, brush, clean, or polish the surface depending on its depth. The particles thus removed from the surface are removed via the rill 7 and do not accumulate between the surface of the pad 11 and the polishing surface 13.

[0075] Figure 8 shows a modified version of accessory 11 according to Figure 7, in which case the shape of the pad 11 is changed. Ultimately, it is possible to give the pad 11 a specific shape, thereby enabling sanding, brushing, cleaning, or polishing of corners or special shapes.

[0076] By giving the pad 11 a complementary shape corresponding to the target processing surface, even special non-flat surfaces can be processed.

[0077] The sanding and polishing surface 13 is subjected to equal force across its entire surface according to its shape, and as a result, the treatment is performed uniformly across the entire surface.

[0078] The present invention is described as illustrative and is not limited to the embodiments and means shown in the figures. Abrasives according to the present invention, accessories for instruments containing such abrasives, and methods for manufacturing such abrasives can be achieved according to various modifications and are within the scope of the present invention.

[0079] Experimental comparison A key feature of the abrasive according to the present invention lies in the upright orientation of the bristles, particularly in the same orientation as the inflorescence of the plant *Ficus umbellata*. In numerous tests, the effectiveness of the abrasive according to the present invention (Ecoforce Green) was compared to a classic nylon polishing brush with stiff bristles without abrasive material, and a nonwoven abrasive with a horizontal open-cell structure containing silica, diamond, and alum oxide as an abrasive.

[0080] Table 1 Wet cleaning of wood surfaces [Table 1] Table 2 Wet cleaning of linoleum surfaces [Table 2] Table 3 Wet cleaning of ceramic floor tiles and joints [Table 3] Table 4 Wet washing of granite surfaces [Table 4]

[0081] The above experiments demonstrate that the abrasive material according to the present invention can add further value to the various applications in which typical nonwoven fabrics and brush bristles are used today. The inventors have found that, due to its upright fiber morphology, its elasticity actually enables better penetration to depth and more effective cleaning without damage from chemical materials, such as typical unwanted deposits. The small abrasive particles applied to (attached to) the fibers help to loosen dirt from the material (object) being cleaned.

[0082] The shape, structure, and upright orientation of the bristles of this invention provide the necessary elasticity, which can also be called brush power, and which is more closely related to function and elasticity. Therefore, based on the spatial orientation of the fiber ends, strength is achieved not only on the upper surface but also in the lower section of the EcoForce (name of the invention). This is in contrast to classic sanding brushes and nonwoven open-cell structures, where these forces can only be achieved in front of the highest point of the surface.

[0083] The tests also demonstrated that, unlike other materials tested for elasticity, the surface structure of the object being treated remained unaffected, and only the dirt was reliably separated. The tests also reliably demonstrated that the selection of bristle length and elasticity, even when using coarse granules, either made abrasion impossible or limited it to a significant degree (data not shown).

[0084] To achieve a polishing effect, the fibers must be short. Therefore, while the EcoForce Pad (name of the present invention) operates similarly to currently used nonwoven fabric and brush pads, it possesses unique properties that result in a completely different final effect without damaging the surface.
