[0001] The present application claims priority to Chinese Patent Application No. 202422717095.0, filed with the China National Intellectual Property Administration on November 6, 2024, and entitled "FABRIC MESH SUBSTRATE, MULTILAYERED FABRIC MESH AND HUMIDIFIER" , Chinese Patent Application No. 202422706711.2, filed with the China National Intellectual Property Administration on November 6, 2024, and entitled "FABRIC MESH SUBSTRATE, MULTILAYERED FABRIC MESH AND HUMIDIFIER" , and Chinese Patent Application No. 202422709398.8, filed with the China National Intellectual Property Administration on November 6, 2024, and entitled "FABRIC MESH SUBSTRATE, MULTILAYERED FABRIC MESH AND HUMIDIFIER" , which are incorporated herein by reference in their entirety.Technical Field
[0002] The present application belongs to the technical field of humidifiers, and particularly to a fabric mesh substrate, a multilayered fabric mesh and a humidifier.Background Art
[0003] Existing evaporative humidifiers include a water tank, a water pump, a multilayered fabric mesh and a fan. The water pump draws water from the water tank to wet the multilayered fabric mesh. An air flow generated by the fan passes through the multilayered fabric mesh, so that moisture in the multilayered fabric mesh is evaporated and then blown out with the air flow, thus realizing air humidification. The key challenge in the industry is to provide a fabric mesh substrate with high water-holding capacity and good hydrophilicity while preventing formation of water films upon wetting, which increase the ventilation resistance, and ensuring a simple structure that is easy to make.Summary
[0004] The present application is intended to solve at least one of the technical problems as mentioned above.
[0005] In view of this, according to a first aspect of an embodiment of the present application, a fabric mesh substrate is provided, including: a first surface layer, a second surface layer and connecting fibers; where the first surface layer and the second surface layer are made of fabrics of weaving threads, the weaving threads each having a plurality of first filaments; the first surface layer is arranged at a distance from the second surface layer, the first surface layer has a plurality of first openings, and the second surface layer has a plurality of second openings; the plurality of first openings correspond to the plurality of second openings; an edge of each of the first openings is connected to an edge of the corresponding second opening by the connecting fibers; and hydrophilicity of the first surface layer or the second surface layer is greater than hydrophilicity of the connecting fibers.
[0006] The present application includes at least the following beneficial effects.
[0007] The first surface layer and the second surface layer are made of fabrics of weaving threads, and are connected by the connecting fibers and remain spaced apart from each other. Water holding is achieved by means of the first surface layer and the second surface layer rather than the connecting fibers. As hydrophilicity of the first surface layer or the second surface layer is greater than hydrophilicity of the connecting fibers, the water-holding capacity of the first surface layer and the second surface layer is improved. The plurality of first openings of the first surface layer correspond to the plurality of second openings of the second surface layer, and the edge of the first opening is connected to the edge of the corresponding second opening by the connecting fibers, which can reduce the ventilation resistance. When blown through the wet fabric mesh substrate, air has a large air-liquid contact area with the first surface layer and the second surface layer and a small contact area with the connecting fibers, so that moisture in the fabric mesh substrate is easily vaporized to produce a large humidification amount.
[0008] According to a second aspect of an embodiment of the present application, a fabric mesh substrate is provided, including: a first surface layer, a second surface layer and connecting fibers; where the first surface layer is a fabric having a plurality of first openings, the first openings being non-circular; the second surface layer is a fabric having a plurality of second openings, the second openings being non-circular; the first opening and the second opening each have an area ranging from 6 mm2 to 48 mm2; the first surface layer is arranged at a distance from the second surface layer, with the plurality of first openings corresponding to the plurality of second openings; and an edge of each of the first openings is connected to an edge of the corresponding second opening by the connecting fibers.
[0009] The present application includes at least the following beneficial effects.
[0010] The first surface layer and the second surface layer are made of fabrics, and are connected by the connecting fibers and remain spaced apart from each other. The plurality of first openings of the first surface layer correspond to the plurality of second openings of the second surface layer, the first openings and the second openings are non-circular, the area of each of the first opening and the second opening is limited to 6 mm2 to 48 mm2, and the edge of the first opening is connected to the edge of the corresponding second opening by the connecting fiber, thereby preventing the formation of water films across the openings after the fabric mesh substrate gets wet, which is conducive to reducing the ventilation resistance of the fabric mesh substrate and improving the ventilation efficiency. When air is blown through the wet fabric mesh substrate, the air is in contact with moisture in the fabric mesh substrate, then the moisture in the fabric mesh substrate is vaporized and flows with the air to humidify the air.
[0011] According to a third aspect of an embodiment of the present application, a fabric mesh substrate is provided, including: a first surface layer, a second surface layer and connecting fibers; where the first surface layer is a fabric having a plurality of first openings, and an edge of the first opening has 8 to 40 first mesh holes; the second surface layer is a fabric having a plurality of second openings, and an edge of the second opening has 8 to 40 second mesh holes; the first surface layer is arranged at a distance from the second surface layer, with the plurality of first openings corresponding to the plurality of second openings; and two connecting fibers extend from at least one of the first mesh holes toward the second mesh holes to connect the edge of the first opening and the edge of the second opening corresponding to the first opening.
[0012] The present application includes at least the following beneficial effects.
[0013] The first surface layer and the second surface layer are made of fabrics, the plurality of first openings of the first surface layer correspond to the plurality of second openings of the second surface layer, and the edge of the first opening is connected to the edge of the corresponding second opening by the connecting fiber, which can reduce the ventilation resistance. The number of the first mesh holes in the whole circle of the edge of the first opening and the number of the second mesh holes in the whole circle of the edge of the second opening are defined, and the number of times the connecting fibers pass through the first surface layer and the second surface layer is determined. The connecting fiber passes straight through the first mesh hole and then the second mesh hole sequentially. The connecting fiber passes through the single first mesh hole or the single second mesh hole only once, which reduces the number of times that the connecting fiber passes through the first mesh hole and the second mesh hole, and simplifies the structure and achieves easy manufacturing. The first surface layer and the second surface layer can be reliably connected by the connecting fibers and remain spaced apart from each other. It takes less steps to produce and process the fabric mesh substrate, with a high processing efficiency. When air is blown through the wet fabric mesh substrate, the air is in contact with moisture in the fabric mesh substrate, then the moisture in the fabric mesh substrate is vaporized and flows with the air to humidify the air. Two connecting fibers extend from the first mesh hole toward the second mesh holes, and the air passes through the area between the first surface layer and the second surface layer with less resistance, thereby reducing the ventilation resistance and increasing the ventilation efficiency. It is easy to control the amount of deformation of the first opening and the second opening, i.e., the size of an overlap between the first opening and the second opening, by controlling the stiffness of the connecting fibers.
[0014] According to a fourth aspect of an embodiment of the present application, a multilayered fabric mesh is provided, including a fabric mesh substrate as described above or a plurality of fabric mesh substrates stacked as described above.
[0015] According to a fifth aspect of an embodiment of the present application, a humidifier is provided, including a multilayered fabric mesh as described above.Brief Description of the Drawings

[0030] To make the technical problems to be solved by the present application, the technical solutions and beneficial effects of the present application clearer, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely used to explain the present application and are not intended to limit the present application.
[0031] In the description of the embodiments of the present application, it should be understood that orientation or position relationships indicated by terms such as “length” , “width” , “up” , “down” , “front” , “rear” , “left” , “right” , “vertical” , “horizontal” , “top” , “bottom” , “inside” , and “outside” are based on orientation or position relationships shown in the accompanying drawings and are merely for ease of description of the embodiments of the present application and simplification of the description, rather than indicating or implying that the apparatuses or elements referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore cannot be construed as limiting the embodiments of the present application.

Thus, the features defined with “first” and “second” may explicitly or implicitly include one or more features. In the description of the present application, the meaning of "a plurality of" is two or more, unless explicitly and specifically defined otherwise.
[0033] In the embodiments of the present application, unless expressly stated or limited otherwise, the terms such as “mounting” , “connecting” , “connection” , and “fixing” should be interpreted broadly, for example, they may be a fixed or detachable connection, or integration; may be a mechanical connection or an electrical connection; or may be a direct connection or an indirect connection by means of an intermediate medium, or may be internal communication between two elements or interaction between the two elements. For those of ordinary skill in the art, the specific meaning of the terms mentioned above in the embodiments of the present application should be construed according to specific circumstances.
[0034] A mesh substrate may serve as a multilayered fabric mesh for an evaporative humidifier and functions to hold water. The mesh substrate includes a first surface layer, a second surface layer, and connecting fibers. The first surface layer is arranged at a distance from the second surface layer, the first surface layer has a plurality of first openings, and the second surface layer has a plurality of second openings. The first openings are arranged corresponding to the second openings. An edge of each of the first openings has a plurality of first mesh holes, and an edge of each of the second openings has a plurality of second mesh holes. The first surface layer and the second surface layer are connected by a plurality of connecting fibers. The connecting fibers pass through the plurality of first mesh holes and the plurality of second mesh holes. The effect of water suction and holding by capillary is achieved through gaps between the connecting fibers, rather than through the first surface layer and the second surface layer.
[0035] In order to improve the water-holding capacity of the mesh substrate, four or more connecting fibers are needed between the first mesh holes and the second mesh holes corresponding thereto, and the filament diameter of and the gaps between the connecting fibers are controlled. The connecting fibers need to be arranged in a curved manner between the first surface layer and the second surface layer to increase the distribution density of the connecting fibers.
[0036] After the mesh substrate gets wet, the smaller the openings of the surface layer, the more likely it is to form water films in the openings. After the water films are formed, the ventilation resistance (air drag) of the mesh substrate increases, and the amount of ventilation and humidification decreases. In order to make the mesh substrate less likely to form the water film, the maximum diagonal of each of the openings of the surface layer is set to have a large length.
[0037] However, in the existing mesh substrate, curved connecting fibers are arranged in a high density, the connecting fibers will be bent toward and filled in a vertical channel between a first opening and a second opening, and the curved connecting fibers in the vertical channel will reduce the porosity of a three-dimensional structure within the vertical channel. After the mesh substrate gets wet, it is likely to form many tiny water films, which increases the ventilation resistance of the mesh substrate. Even if a maximum diagonal length of the openings of the surface layer is greater than 3 mm, it cannot effectively overcome the problem that many water films are formed on the mesh substrate.
[0038] The greater the maximum diagonal length of the openings of the surface layer, the more difficult it is to control the stiffness of the mesh substrate. The maximum diagonal length of the openings of the surface layer is greater than 3 mm, and the connecting fibers are arranged in a curved manner with low stiffness. The bending and inclination of the connecting fibers increase when the mesh substrate is pulled by a force during removal and washing. The size and shape of the openings of the surface layer is mainly dependent on the stiffness of the connecting fibers. After the connecting fibers are bent, the first openings of the first surface layer will be misaligned with the second openings of the second surface layer, and the mesh substrate has a poor recovery effect.
[0039] Referring to Figs. 1 and 2, according to a first aspect of an embodiment of the present application, a fabric mesh substrate 100 is provided, including: afirst surface layer 10, a second surface layer 20, and connecting fibers 40. With reference to Fig. 3, the first surface layer 10 and the second surface layer 20 are made of fabrics of weaving threads 30, the weaving threads 30 each having a plurality of first filaments 31. Referring to Fig. 1, the first surface layer 10 is arranged at a distance from the second surface layer 20, the first surface layer 10 has a plurality of first openings 11, and the second surface layer 20 has a plurality of second openings 21. The plurality of first openings 11 correspond to the plurality of second openings 21. An edge 12 of the first opening 11 is connected to an edge 22 of the second opening 21 corresponding to the first opening 11 by the connecting fibers 40. Hydrophilicity of the first surface layer 10 or the second surface layer 20 is greater than hydrophilicity of the connecting fibers 40.
[0040] Referring to Fig. 1, the plurality of first openings 11 corresponding to the plurality of second openings 21 may refer to the first openings 11 being in communication with the second openings 21 on a one-to-one basis.
[0041] In the fabric mesh substrate 100 according to an embodiment of the present application, the first surface layer 10 and the second surface layer 20 are made of fabrics of weaving threads 30, and are connected by the connecting fibers 40 and remain spaced apart from each other. Water holding is achieved by means of the first surface layer 10 and the second surface layer 20 rather than the connecting fibers 40. As the hydrophilicity of the first surface layer 10 or the second surface layer 20 is greater than the hydrophilicity of the connecting fibers 40, the water-holding capacity of the first surface layer 10 and the second surface layer 20 is improved. The plurality of first openings 11 of the first surface layer 10 correspond to the plurality of second openings 21 of the second surface layer 20, and the edge 12 of the first opening 11 is connected to the edge 22 of the second opening 21 by the connecting fibers 40, which can reduce the ventilation resistance. When blown through the wet fabric mesh substrate 100, air has a large air-liquid contact area with the first surface layer 10 and the second surface layer 20 and a small contact area with the connecting fibers 40, so that moisture 1 in the fabric mesh substrate 100 is easily vaporized to produce a large humidification amount.
[0042] Referring to Figs. 1 and 2, the first surface layer 10 is a fabric having a plurality of first openings 11, the first openings 11 being non-circular. The second surface layer 20 is a fabric having a plurality of second openings 21, the second openings 21 being non-circular. With reference to Fig. 6, the first opening 11 and the second opening 21 each have an area ranging from 6 mm2 to 48 mm2.
[0043] In the fabric mesh substrate 100 according to an embodiment of the present application, the first surface layer 10 and the second surface layer 20 are made of fabrics, and are connected by the connecting fibers 40 and remain spaced apart from each other. The plurality of first openings 11 of the first surface layer 10 are in communication with the plurality of second openings 21 of the second surface layer 20 correspondingly, the first openings 11 and the second openings 21 are non-circular, the area of each of the first opening 11 and the second opening 21 is limited to 6 mm2 to 48 mm2, and the edge 12 of the first opening 11 is connected to the edge 22 of the second opening 21 by the connecting fiber 40, thereby preventing the formation of water films across the openings after the fabric mesh substrate 100 gets wet, which is conducive to reducing the ventilation resistance of the fabric mesh substrate 100 and improving the ventilation efficiency. When air is blown through the wet fabric mesh substrate 100, the air is in contact with moisture in the fabric mesh substrate 100, then the moisture in the fabric mesh substrate 100 is vaporized and flows with the air to humidify the air.
[0044] In some embodiments, referring to Figs. 1 and 2, the edge 12 of the first opening 11 has a number of first mesh holes 13 that ranges from 8 to 40. The edge 22 of the second opening 21 has a number of second mesh holes 23 that ranges from 8 to 40.
[0045] Referring to Figs. 1 to 3, the edge 12 of the first opening 11 has 8 to 40 first mesh holes 13. The edge 22 of the second opening 21 has 8 to 40 second mesh holes 23. Two connecting fibers 40 extend from at least one of the first mesh holes 13 toward the second mesh holes 23 to connect the edge 12 of the first opening 11 and the edge 22 of the second opening 21 corresponding to the first opening 11.
[0046] In the fabric mesh substrate 100 according to an embodiment of the present application, the first surface layer 10 and the second surface layer 20 are made of fabrics, the plurality of first openings 11 of the first surface layer 10 correspond to the plurality of second openings 21 of the second surface layer 20, and the edges 12 of the first openings 11 are connected to the edges 22 of the second openings 21 by the connecting fibers 40, which can reduce the ventilation resistance. The number of the first mesh holes 13 in the whole circle of the edge 12 of a single first opening 11 and the number of the second mesh holes 23 in the whole circle of the edge 22 of a single second opening 21 are defined, and the number of times the connecting fibers 40 pass through the first surface layer 10 and the second surface layer 20 is determined. The connecting fiber 40 passes straight through the first mesh hole 13 and then the second mesh hole 23 sequentially. The connecting fiber 40 passes through the single first mesh hole 13 or the single second mesh hole 23 only once, which reduces the number of times that the connecting fiber 40 passes through the first mesh hole 13 and the second mesh hole 23, and simplifies the structure and achieves easy manufacturing. The first surface layer 10 and the second surface layer 20 can be reliably connected by the connecting fibers 40 and remain spaced apart from each other. It takes less steps to produce and process the fabric mesh substrate 100, with a high processing efficiency. When air is blown through the wet fabric mesh substrate 100, the air is in contact with moisture in the fabric mesh substrate 100, then the moisture in the fabric mesh substrate 100 is vaporized and flows with the air to humidify the air. Two connecting fibers 40 extend from the first mesh hole 13 toward the second mesh hole 23, and the air passes through the area between the first surface layer 10 and the second surface layer 20 with less resistance, thereby reducing the ventilation resistance and increasing the ventilation efficiency. It is easy to control the amount of deformation of the first opening 11 and the second opening 21, i.e., the size of an overlap between the first opening 11 and the second opening 21, by controlling the stiffness of the connecting fibers 40.
[0047] For the first and third types of fabric mesh substrates 100, in some embodiments, referring to Figs. 2 and (a) and (b) in Fig. 6, Fig. 6 is a structural schematic diagram of a first opening of the first surface layer, where the second opening of the second surface layer has a similar structure. The first opening 11 is non-circular; and the second opening 21 is non-circular.
[0048] For the second and third types of fabric mesh substrates 100, in some embodiments, as the hydrophilicity of the first surface layer 10 or the second surface layer 20 is greater than the hydrophilicity of the connecting fibers 40, the water-holding capacity of the first surface layer 10 or the second surface layer 20 is improved. The hydrophilicity refers to water retention or water absorption. Water holding is achieved by means of the first surface layer 10 and the second surface layer 20 rather than the connecting fibers 40. When blown through the wet fabric mesh substrate 100, air has a large air-liquid contact area with the first surface layer 10 and the second surface layer 20 and a small contact area with the connecting fibers 40, so that moisture 1 in the fabric mesh substrate 100 is easily vaporized to produce a large humidification amount.
[0049] The first surface layer 10 and the second surface layer 20 are made of fabrics of weaving threads 30, and the weaving threads 30 each may be formed of a plurality of first filaments 31 by interweaving.
[0050] In some embodiments, referring to Fig. 3, each of the first filaments 31 is at least one of a synthetic fiber, a natural fiber and a regenerated fiber. These filaments may be synthesized into the weaving thread 30. The weaving thread 30 may be woven to form the first surface layer 10 and the second surface layer 20. The synthetic fibers may be polyester, polyamide, acrylic, polypropylene, vinylon, and polyvinyl chloride fibers, etc. The natural fibers may be cotton yarn, wool, silk, and hemp, etc. The regenerated fibers may be lyocell fibers, and chitosan fibers, etc.
[0051] In some embodiments, referring to Fig. 3, water-holding grooves 32 are formed in surfaces of at least some of the first filaments 31. The water-holding grooves 32 may hold more moisture 1. This is conducive to improving the water-holding capacity of the first surface layer 10 and the second surface layer 20.
[0052] As an example, as shown in (a) of Fig. 3, some of the first filaments 31a have water-holding grooves 32, while the other first filaments 31b have no water-holding groove 32.
[0053] As an example, as shown in (b) of Fig. 3, all of the first filaments 31a have water-holding grooves 32.
[0054] In some embodiments, referring to (a) to (d) of Fig. 4, at least some of the first filaments 31 may have cross sections in a special shape, such as a cross, acompound-leaf-like shape, a polygon, a W or a U, for forming the water-holding grooves 32. The compound-leaf-like shape may be trilobal, which is similar to three leaves distributed in a Y shape. Each side of the polygon may be recessed inwardly to form a water-holding groove 32. The polygon may be a triangle, a quadrangle, or a pentagon, etc. The first filament 31 having the above cross-section may form the water-holding groove 32, and moisture may be held in the water-holding groove 32, thus improving the water-holding capacity of the first surface layer 10 and the second surface layer 20, with reference to Fig. 1.
[0055] In some embodiments, the weaving thread 30 has a hydrophilic layer (not shown in the figures) , and the hydrophilic layer of the weaving thread 30 brings the fabric mesh substrate 100 good hydrophilicity.
[0056] In some embodiments, the hydrophilic layer of the weaving thread 30 may be provided on an outer surface of the first filament 31. In the process of synthesizing the weaving thread 30 from the first filaments 31, high polymers with hydrophilic groups, such as polybutyl acrylate and methyl methacrylate, are blended and added, and grafting modification is carried out on molecular chains of the first filaments 31, which improves the hydrophilicity of the weaving thread 30, and is conducive to long-lasting retention of the water-holding capacity of the first surface layer 10 and the second surface layer 20.
[0057] Compared with the way of post-coating the mesh substrate with a hydrophilic oiling agent to achieve moisture absorption, whereby the hydrophilic oiling agent may be desorbed after long-term use and multiple washes, causing a reduced hydrophilic effect, this embodiment has the advantages that a hydrophilic layer has been formed on the outer surface of the first filament 31 during manufacturing of the weaving thread 30, so the fabric mesh substrate 100 can also maintain a long-lasting and stable hydrophilic effect to meet the needs of long-term use under external forces (e.g., scrubbing and rinsing) , cleaning with additional substances (e.g., citric acid and detergent) , and high temperature (e.g., water baths above 60℃) .
[0058] In some embodiments, the weaving thread 30 has an antibacterial layer (not shown in the figures) . The antibacterial layer of the weaving thread 30 makes the fabric mesh substrate 100 antibacterial and mildew-proof.
[0059] In some embodiments, the antibacterial layer of the weaving thread 30 may be provided on the outer surface of the first filament 31. Antibacterial agents, which may be inorganic, organic and natural extracts of multiple types, such as copper, zinc, graphene, phenols, and organic acids extracted from plants are blended and added in the process of synthesizing the weaving thread 30 from the first filaments 31. These antibacterial agents may be embedded to the weaving thread 30.
[0060] Compared with the way of post-coating the mesh substrate with an antibacterial oiling agent (e.g., quaternary ammonium salt) to achieve the antibacterial effect, whereby the antibacterial oiling agent may be desorbed after long-term use and multiple washes, causing a reduced antibacterial effect, this embodiment has the advantages that an antibacterial layer has been formed on the outer surface of the first filament 31 during manufacturing of the weaving thread 30, so the subsequent coating process may be omitted, and the fabric mesh substrate 100 can also maintain a long-lasting and stable antibacterial and mildew-proof effect to meet the needs of long-term use under external forces (e.g., scrubbing and rinsing) , cleaning with additional substances (e.g., citric acid and detergent) , and high temperature (e.g., water baths above 60℃) .
[0061] As an example, an antibacterial filament is embedded in the first filament 31, the first filament 31 and the antibacterial filament are interwoven to form the weaving thread 30, with the antibacterial filament serving as the antibacterial layer. The process of post-coating the fabric mesh substrate 100 with the antibacterial oiling agent is not needed.
[0062] In some embodiments, referring to Figs. 2 and 5, the edge 12 of the first opening 11 has a plurality of first mesh holes 13, the edge 22 of the second opening 21 has a plurality of second mesh holes 23, and two connecting fibers 40 extend from at least one of the first mesh holes 13 toward the second mesh holes 23 to connect the edge 12 of the first opening 11 and the edge 22 of the second opening 21.
[0063] The plurality of first mesh holes 13 may be arranged in sequence along the edge 12 of the first opening 11, and the plurality of second mesh holes 23 may be arranged in sequence along the edge 22 of the second opening 21. The two connecting fibers 40 extending from the single first mesh hole 13 toward the second mesh holes 23 visually are actually the same connecting fiber 40 passing through the single first mesh hole 13 in an in-and-out manner.
[0064] The connecting fiber 40 passes straight through the first mesh hole 13 and then the second mesh hole 23 sequentially. The connecting fiber 40 passes through the single first mesh hole 13 or the single second mesh hole 23 only once, which reduces the number of times that the connecting fiber 40 passes through the first mesh hole 13 and the second mesh hole 23, and simplifies the structure and achieves easy manufacturing. The first surface layer 10 and the second surface layer 20 can be reliably connected by the connecting fibers 40 and remain spaced apart from each other. It takes less steps to produce and process the fabric mesh substrate 100, with a high processing efficiency. Two connecting fibers 40 extend from the first mesh hole 13 toward the second mesh hole 23, and the air passes through the area between the first surface layer 10 and the second surface layer 20 with less resistance, thereby reducing the ventilation resistance and increasing the ventilation efficiency. It is easy to control the amount of deformation of the first opening 11 and the second opening 21, i.e., the size of an overlap between the first opening 11 and the second opening 21, by controlling the stiffness of the connecting fibers 40.
[0065] In the process of manufacturing the fabric mesh substrate 100, the first surface layer 10, the second surface layer 20, and the connecting fibers 40 are simultaneously manufactured using a conventional mesh substrate process.
[0066] Referring to Fig. 2, the edge 12 of the first opening 11 has a plurality of first mesh holes 13 arranged in sequence, the edge 22 of the second opening 21 has a plurality of second mesh holes 23 arranged in sequence, the first opening 11 is in communication with the second opening 21, and the edge 12 of the first opening 11 corresponds to the edge 22 of the second opening 21. The connecting fiber 40 may alternately pass through different first mesh holes 13 and second mesh holes 23 in an edge extension direction, i.e., the connecting fiber 40 passes through one first mesh hole 13, one second mesh hole 23, a latter first mesh hole 13, a latter second mesh hole 23, etc., thereby realizing a connection between the first surface layer 10 and the second surface layer 20.
[0067] As an example, the connecting fiber 40, when passing through some of the first mesh holes 13 or some of the second mesh holes 23, may first skip one or two of the first mesh holes 13 or the second mesh holes 23 and pass through a latter first mesh hole 13 or a latter second mesh hole 23, then back to pass through the previously skipped first mesh hole 13 or second mesh hole 23, i.e., the connecting fiber 40 does not pass through the first mesh holes 13 and the second mesh holes 23 in a completely sequential order, thereby realizing a connection between the first surface layer 10 and the second surface layer 20.
[0068] The edge 12 of the first opening 11 refers to an edge area that encloses the first opening 11. The first surface layer 10 has a plurality of first openings 11, with a common edge formed between two adjacent first openings 11. The first mesh holes 13 at the common edge may be counted into the number of first mesh holes 13 of the edge 12 of the single first opening 11 of the two adjacent first openings 11. The second mesh holes 23 of the second opening 21 of the second surface layer 20 have similar situations.
[0069] The number of the first mesh holes 13 in the whole circle of the edge 12 of the single first opening 11 and the number of the second mesh holes 23 in the whole circle of the edge 22 of the single second opening 21 are defined, and the number of times the connecting fibers 40 pass through the first surface layer 10 and the second surface layer 20 within a predetermined area is determined, so that the first surface layer 10 and the second surface layer 20 are reliably connected and remain spaced apart from each other. Moreover, it is not easy for the connecting fibers 40 to be bent toward and filled in the vertical channel between the first opening 11 and the second opening 21, thus preventing the formation of the water film after the fabric mesh substrate 100 gets wet.
[0070] As an example, the number of the first mesh holes 13 of the edge 12 of the first opening 11 and the number of the second mesh holes 23 of the edge 22 of the second opening 21 are both 16 or 24. With the connecting fibers 40 which pass through the first mesh holes 13 and the second mesh holes 23, the first surface layer 10 and the second surface layer 20 can be reliably connected and remain spaced apart from each other.
[0071] In some embodiments, the number of the first mesh holes 13 and the number of the second mesh holes 23 may be equal. The connecting fiber 40 passes through the first mesh hole 13 and the second mesh hole 23 in an in-and-out manner, which can realize a reliable connection between the first surface layer 10 and the second surface layer 20.
[0072] In some other embodiments, the number of first mesh holes 13 and the number of second mesh holes 23 may not be equal. For example, the number of the first mesh holes 13 is less than the number of the second mesh holes 23, the connecting fibers 40 may not pass through some of the second mesh holes 23 but through most of the second mesh holes 23 and all of the first mesh holes 13, which can realize a reliable connection between the first surface layer 10 and the second surface layer 20.
[0073] In some embodiments, referring to Fig. 2, the connecting fiber 40 is a single second filament, rather than a fiber synthesized from a plurality of filaments. The second filament has a filament diameter ranging from 20μm to 120μm, which is large in filament diameter. In this way, the second filament between the first surface layer 10 and the second surface layer 20 is not susceptible to substantial bending, but maintains a stiffness in the thickness direction of the fabric mesh substrate 100, and may be slightly bent.
[0074] With the large filament diameter and stiffness of the connecting fiber 40, the overall fabric mesh substrate 100 has good mechanical properties, the fabric mesh substrate 100 recovers well after being pulled and repeatedly scrubbed, and the misalignment of the first surface layer 10 and the second surface layer 20 is reduced. The connecting fiber 40 is less likely to be bent toward or be filled in the vertical channel between the first opening 11 and the second opening 21,which reduces the ventilation resistance and prevents the formation of the water film after the fabric mesh substrate 100 gets wet, achieving good amount of ventilation and humidification. If the filament diameter of the connecting fiber 40 is greater than 100μm, the water hanging or holding capacity of the fabric mesh substrate 100 will be deteriorated.
[0075] As an example, the second filament has a filament diameter ranging from 50μm to 80μm. When the second filament has a circular cross-section, the outer perimeter of the second filament ranges from 157μm to 251μm.
[0076] In some embodiments, the connecting fibers 40 are synthetic fibers, natural fibers or regenerated fibers. The synthetic fibers may be polyester, polyamide, acrylic, polypropylene, vinylon, and polyvinyl chloride fibers, etc. The natural fibers may be cotton yarn, wool, silk, and hemp, etc. The regenerated fibers may be lyocell fibers, and chitosan fibers, etc.
[0077] In some embodiments, referring to Figs. 1 and 2, the connecting fiber 40 has an antibacterial layer (not shown in the figures) . The antibacterial layer of the connecting fiber 40 makes the fabric mesh substrate 100 antibacterial and mildew-proof. Antibacterial agents added into the connecting fiber 40 may be inorganic, organic and natural extracts of multiple types, such as copper, zinc, graphene, phenols, and organic acids extracted from plants. These antibacterial agents can be attached to the surface of the connecting fiber 40.
[0078] As an example, the second filament may be a polyester fiber with a filament diameter of 56μm, and is embedded with a graphene antibacterial agent. The second filament has a certain stiffness, and will not be bent substantially. The second filament is antibacterial and mildew-proof.
[0079] In some embodiments, the surface of the second filament has water-holding grooves (not shown in the figures) . The water-holding grooves may hold more moisture, which is conducive to improving the water-holding capacity of the fabric mesh substrate 100.
[0080] In some embodiments, referring to (a) in Fig. 3, in the same weaving thread 30, some of the first filaments 31a are different from the other first filaments 31b in cross section. Some of the first filaments 31a may have cross sections in a special shape, such as a cross, a compound-leaf-like shape, a polygon, a W or a U, for forming the water-holding grooves 32. The other first filaments 31b may have circular cross sections, etc. The plurality of first filaments 31 are interwoven to form the weaving thread 30, so that the weaving thread 30 or the surface layer has characteristics of the different first filaments 31.
[0081] As an example, a first filament 31b having a circular cross-section is used as a reinforcing filament, a plurality of first filaments 31a having special-shaped cross-sections are used as water-holding filaments, and the plurality of water-holding filaments are interwoven at the periphery of the reinforcing filament. The weaving thread 30 or the surface layer has a certain strength and water-holding capacity.
[0082] In some other embodiments, referring to (b) in Fig. 3, in the same weaving thread 30, cross sections of all the first filaments 31 have the same shape. The cross sections of all the first filaments 31 may have a special shape to form the water-holding grooves 32 so as to improve the water-holding capacity of the weaving thread 30 or the surface layer.
[0083] As an example, the cross-sections of the first filaments 31 may be cross-shaped, and a higher water-holding capacity is achieved by means of a large number of water-holding grooves 32.
[0084] In some embodiments, referring to Fig. 3, the first surface layer 10 and the second surface layer 20 are made of the weaving threads 30, where the weaving thread 30 has a weight ranging from 30 g to 300 g over a length of 9000 m. The weaving thread 30 has a plurality of first filaments 31. The number of the first filaments 31 of the same weaving thread 30 ranges from 18 to 500. By defining the fineness of the weaving thread 30 and the number of the first filaments 31 in the weaving thread 30, the weaving threads 30 are woven to form the first surface layer 10 and the second surface layer 20 with good water absorption and mechanical properties and a stable structure.
[0085] Denier (D) is an expression for the fineness of a fiber and refers to the weight of the weaving thread 30 having a length of 9000 m, and is also known as Nden. A larger D represents a thicker weaving thread 30. Filament (F) indicates the number of filaments of each weaving thread 30.
[0086] As an example, the weaving thread 30 used for the first surface layer 10 and the second surface layer 20 may be a 150D / 144F polyester yarn. 150D means that the weight of the weaving thread 30 having a length of 9000 m is 150 g. The weaving thread 30 is composed of 144 filaments. The weaving thread 30 may be made using a conventional blending process, where monofilament polyester fibers having crossed or triangular cross-sections and embedded with a graphene antibacterial agent may be used.
[0087] As an example, the weaving thread 30 used for the first surface layer 10 and the second surface layer 20 may be a 150D / 96F polyester yarn. 150D means that the weight of the weaving thread 30 having a length of 9000 m is 150 g. The weaving thread 30 is composed of 96 filaments. The weaving thread 30 may be made using a conventional blending process, where monofilament polyester fibers having crossed or triangular cross-sections and embedded with a graphene antibacterial agent may be used.
[0088] As an example, the weaving thread 30 used for the first surface layer 10 and the second surface layer 20 may be a 300D / 96F polypropylene yarn. 300D means that the weight of the weaving thread 30 having a length of 9000 m is 300 g. The weaving thread 30 is composed of 96 filaments. The weaving thread 30 may be made using a conventional blending process, where monofilament polypropylene fibers having triangular cross-sections and embedded with a graphene antibacterial agent may be used.
[0089] In some embodiments, referring to Fig. 1, the first surface layer 10 is provided with a first uneven hydrophobic layer (not shown in the figures) on the surface; and the second surface layer 20 is provided with a second uneven hydrophobic layer (not shown in the figures) on the surface. The uneven hydrophobic layers can enhance the water absorption and water-holding capacity of the surface layers. The uneven hydrophobic layer may be formed by adhering hydrophobic particles on the surfaces of the first surface layer 10 and the second surface layer 20 to form tiny uneven structures that have a water-holding function. Hydrophobic particles may be ceramic particles, silica particles, etc.
[0090] In some embodiments, referring to Fig. 1, the fabric mesh substrate 100 is a double-layer woven structure, i.e., the first surface layer 10 and the second surface layer 20 are connected by the connecting fibers 40. The connecting fibers 40 serve as warp fibers and filaments of the first surface layer 10 and the second surface layer 20 serve as weft fibers. The warp density ranges from 16 ends / inch to 50 ends / inch and the weft density ranges from 14 picks / inch to 45 picks / inch. 1 in. (inch) equals 0.0254 meters (m) . By defining the fiber distribution in both the warp and weft directions of the fabric mesh substrate 100, the fabric mesh substrate 100 has good mechanical properties and a stable structure. The first filaments 31 in the first surface layer 10 and the second surface layer 20 have the water-holding grooves 32, and accordingly the fabric mesh substrate 100 has a good water-holding capacity.
[0091] As an example, the fabric mesh substrate 100 is of a double-layer woven structure with a warp density of 30 ends / inch and a weft density of 26 picks / inch. That is, within 1 inch of the weft direction, there are 30 connecting fibers 40 extending in the warp direction, and visually there are a plurality of connecting fibers 40, which, as can be seen from the preceding, may be the same connecting fiber 40 passing through the first mesh holes 13 (the second mesh holes 23) in an in-and-out manner. Within 1 inch of the warp direction, there are 26 first filaments 31 extending in the weft direction.
[0092] As an example, the fabric mesh substrate 100 is of a double-layer woven structure with a warp density of 42 ends / inch and a weft density of 30 picks / inch. That is, within 1 inch of the weft direction, there are 42 connecting fibers 40 extending in the warp direction, and visually there are a plurality of connecting fibers 40, which, as can be seen from the preceding, may be the same connecting fiber 40 passing through the first mesh holes 13 (the second mesh holes 23) in an in-and-out manner. Within 1 inch of the warp direction, there are 30 first filaments 31 extending in the weft direction.
[0093] The non-circular shape refers to a shape other than a circle, such as an ellipse and a polygon, where the polygon may refer to a rectangle, a square, a hexagon, etc. The hexagon may be a regular hexagon or a non-regular hexagon. The first opening 11 and the second opening 21 are set to be non-circular, which prevents the formation of water films in the openings after the fabric mesh substrate 100 gets wet and is conducive to reducing the ventilation resistance of the fabric mesh substrate 100 and improving the ventilation efficiency.
[0094] As an example, referring to (a) in Fig. 6, the first opening 11 and the second opening 21 are non-regular hexagons. At least two sides of the non-regular hexagon have unequal length, making it difficult to form water films in the openings, which is conducive to reducing the ventilation resistance and improving the ventilation efficiency.
[0095] As an example, referring to (b) in Fig. 6, the first opening 11 and the second opening 21 are ellipses, making it difficult to form water films in the openings, which is conducive to reducing the ventilation resistance and improving the ventilation efficiency.
[0096] In some embodiments, referring to (a) in Fig. 6, the first opening 11 or the second opening 21 is in the shape of a hexagon, a longer diagonal a1 of the hexagon has a length ranging from 3 mm to 6 mm, and a shorter diagonal a2 of the hexagon has a length ranging from 2 mm to 5 mm. The longer diagonal a1 of the hexagon is the longest diagonal and the shorter diagonal a2 is the shortest diagonal. By defining the length range of the diagonal of the hexagon, the size of the first opening 11 or the second opening 21 can be determined, so that it is less likely to form water films in the openings after the fabric mesh substrate 100 gets wet.
[0097] In some embodiments, referring to Fig. 6, the diagonal (a1, a2) of the first opening 11 and the diagonal of the second opening 21 each have a length ranging from 2 mm to 6 mm. The diagonal (a1, a2) of the first opening 11 may be the longer diagonal a1 or the shorter diagonal a2 of the first opening 11. It prevents the formation of water films across the openings after the fabric mesh substrate 100 gets wet, which is conducive to reducing the ventilation resistance of the fabric mesh substrate 100 and improving the ventilation efficiency.
[0098] It can be understood that the diagonal length of the first opening / second opening can be converted to the area of the first opening / the second opening of the fabric mesh substrate. In an example of the first opening, the product of the length of longer diagonal and the length of the shorter diagonal of the first opening is approximately equal to the area of the first opening.
[0099] As an example, the first opening 11 or the second opening 21 is in the shape of a hexagon, a longer diagonal a1 of the hexagon has a length of 4.5 mm, and a shorter diagonal a2 of the hexagon has a length of 3 mm.
[0100] In some embodiments, referring to (b) in Fig. 6, the first opening 11 or the second opening 21 is in the shape of an ellipse, a longer diagonal a1 of the ellipse has a length ranging from 4 mm to 6 mm, and a shorter diagonal a2 of the ellipse has a length ranging from 2 mm to 5 mm. The longer diagonal a1 of the ellipse is a major axis and the shorter diagonal a2 is a minor axis. By defining the length range of the diagonal of the ellipse, the size of the first opening 11 or the second opening 21 can be determined, so that it is less likely to form water films in the openings after the fabric mesh substrate 100 gets wet.
[0101] As an example, the first opening 11 or the second opening 21 is in the shape of an ellipse, the longer diagonal a1 of the ellipse has a length of 6 mm, and the shorter diagonal a2 of the ellipse has a length of 4 mm.
[0102] In some embodiments, referring to Fig. 1, the fabric mesh substrate 100 ranges from 3 mm to 20 mm in thickness D. By defining the thickness of the fabric mesh substrate 100, the fabric mesh substrate 100 may hold a predetermined amount of moisture, and the air flow and the moisture are in contact with each other for a period of time, thereby improving the humidification effect. The fabric mesh substrate 100 ranges from 80 g / m2 to 1500 g / m2 in weight. The fabric mesh substrate 100 has a proper weight and is able to hold moisture.
[0103] As an example, the thickness of the fabric mesh substrate 100 is 4.5 mm and the weight of the fabric mesh substrate 100 is 290 g / m2.
[0104] As an example, the thickness of the fabric mesh substrate 100 is 6 mm and the weight of the fabric mesh substrate 100 is 450 g / m2.
[0105] In some embodiments, referring to Fig. 1, the fabric mesh substrate 100 has a water-holding capacity per unit weight in the range from 1g / g to 5g / g. The ratio of the water-holding capacity of the fabric mesh substrate 100 to the weight of the fabric mesh substrate 100 itself can be used as a basis for type selection of the first filament 31. The fabric mesh substrate 100 is made to have a certain water-holding capacity and weight.
[0106] In some embodiments, water holding is achieved by means of the first surface layer 10 and the second surface layer 20 rather than the connecting fibers 40. As the hydrophilicity of the first surface layer 10 or the second surface layer 20 is greater than the hydrophilicity of the connecting fibers 40, the water-holding capacity of the first surface layer 10 and the second surface layer 20 is improved. The hydrophilicity refers to water retention or water absorption.
[0107] The water-holding grooves 32 provided on the surfaces of the first filaments 31 may hold more moisture 1. This is conducive to improving the water-holding capacity of the first surface layer 10 and the second surface layer 20. Water holding is achieved by means of the first surface layer 10 and the second surface layer 20 rather than the connecting fibers 40.
[0108] Referring to Fig. 7, an embodiment of the present application provides a multilayered fabric mesh 200, which includes a fabric mesh substrate 100 according to any one of the above embodiments or a plurality of fabric mesh substrates 100 stacked as described above. The multilayered fabric mesh 200 of the embodiment of the present application has the effect of the fabric mesh substrate 100 as described above.
[0109] In order to meet the overall performance requirements of the humidifier such as a predetermined humidification amount, air volume, power consumption, noises, etc., the number of fabric mesh substrates 100 is set as desired, for example, 2 to 6 layers of fabric mesh substrates 100 are stacked. When a plurality of fabric mesh substrates 100 are stacked, the plurality of fabric mesh substrates 100 may be arranged in a stacked manner. The plurality of fabric mesh substrates 100 may be fixed by means of edge sewing. The form of the plurality of fabric mesh substrates 100 is adjusted according to the form of the multilayered fabric mesh 200. The air speed of the multilayered fabric mesh 200 of this embodiment may range from 0.3 m / sec to 4.0 m / sec.
[0110] As an example, referring to Fig. 7, when a cylindrical multilayered fabric mesh 200 is desired, a plurality of fabric mesh substrates 100 are stacked, with the edges sewed, to obtain a rectangular mesh substrate substrate, and the cylindrical multilayered fabric mesh 200 is obtained by crimping long edges of the rectangular mesh substrate substrate and sewing two short edges together.
[0111] As an example, when a sheet-like multilayered fabric mesh 200 is desired, a plurality of fabric mesh substrates 100 are stacked, with the edges sewed, to obtain the sheet-like multilayered fabric mesh 200.
[0112] An embodiment of the present application provides a humidifier, including a multilayered fabric mesh 200 as described above. The humidifier of the embodiment of the present application has the effect of the fabric mesh substrate 100 as described above.
[0113] As an example, the humidifier includes a water tank, a water pump, a multilayered fabric mesh 200 and a fan. The water pump draws water from the water tank to wet the multilayered fabric mesh 200. An air flow generated by the fan passes through the multilayered fabric mesh 200, so that moisture in the multilayered fabric mesh 200 is evaporated and then blown out with the air flow, thus realizing air humidification.
[0114] The following experiments are performed on the multilayered fabric mesh and the humidifier in the embodiments of the present application. As shown in Tables 1, 2 and 3 below, in multiple groups of experiments, by varying several parameters of the multilayered fabric mesh / mesh substrate of the humidifier, such as thickness (mm) , layer number of mesh substrate, warp density (ends / inch) / weft density (picks / inch) , weight (g / m2) , filament diameter of connecting fiber, shape of first opening / second opening, and size of first opening / second opening (mm) and by controlling quantitative and non-quantitative relationships between the parameters, numerical values such as the water absorption rate, ventilation resistance and humidification amount of the multilayered fabric mesh / mesh substrate can be obtained.
[0115] Referring to Fig. 6, the first opening 11 or the second opening 21 may be a quasi-hexagon or quasi-ellipse. The quasi-hexagon may be any type of hexagon with unequal side lengths and different angles. The quasi-ellipse, known as a deformed ellipse, is a shape obtained by deforming the projection of an original ellipse. A longer diagonal a1 of the quasi-hexagon or quasi-ellipse has a length ranging from 3 mm to 6 mm, and a shorter diagonal a2 of the quasi-hexagon or quasi-ellipse has a length ranging from 2 mm to 5 mm. The multilayered fabric mesh / mesh substrate with the above opening features has a good humidification effect and superior wind resistance.
[0116] For example, as shown in Tables 1, 2 and 3 below, the thickness of a single layer of mesh substrate in this experiment can be controlled between 3.0-8.0 mm,and by increasing the layer number of the mesh substrate, the wind resistance of mesh substrates with different thicknesses can be measured. Under the same measurement conditions, according to solution 3.1, the first opening 11 or the second opening 21 is in the shape of a quasi-hexagon, with the length of the longer diagonal set to 5.0 mm and the length of the shorter diagonal set to 3.0 mm. Alternatively, according to solution 3, the first opening 11 or the second opening 21 is in the shape of a quasi-hexagon, with the length of the longer diagonal set to 4.0 mm and the length of the shorter diagonal set to 2.0 mm, where the water absorption rate of the mesh substrate may achieve 3.0 or above, the drag coefficient of the single layer of mesh substrate can be controlled to be 2.0Pa or below, and multiple layers (N≥2) of mesh substrates are stacked such that the air drag of the multi-layer mesh substrate is less than N *2.0Pa.
[0117] Preferably, the warp density of the mesh substrate is controlled to between 30-37 ends / inch, the weft density is controlled to between 23-26 picks / inch, and the thickness of the single layer of mesh substrate is controlled to between 3.0-5.0 mm. As in solution 3.1 of Table 2, when the warp density is controlled at 30.5 ends / inch, the weft density is controlled at 24 picks / inch, and the thickness of the single layer of mesh substrate is controlled at 3 mm. The use of the single layer of mesh substrate or the stacked multi-layer mesh substrate has a good humidification effect.
[0118] Preferably, the weight (g / m2) of the mesh substrate is set to 100-350 g / m2, and the humidification amount of the mesh substrate can be up to 1000 ml / h or above.
[0119] The multilayered fabric mesh / mesh substrate with the above opening features has a high water absorption rate, a low ventilation resistance and a large humidification amount.
[0120] Factors such as the number of the first / second openings, the shape and size of the first / second openings, the filament diameter of the connecting fibers, and the number of fibers will affect the water absorption and dewatering of the mesh substrate. Good water absorption can increase the weight of water absorbed by the multilayered fabric mesh / mesh substrate having the same area and weight. Good dewatering can increase the humidification effect of the multilayered fabric mesh / mesh substrate under the same air drag.
[0121] Table 1: Data of water absorption rate of multilayered fabric mesh / mesh substrate
[0122] The measurement standard used in the experiment for measuring the water absorption rate is to immerse the multilayered fabric mesh for 5 minutes, remove the multilayered fabric mesh and hang same for 2 minutes and then weigh same to obtain the total weight of the multilayered fabric mesh and the sucked water after water absorption.
[0123] Water absorption rate= (total weight of multilayered fabric mesh and sucked water after water absorption-weight of multilayered fabric mesh before water absorption) / weight of multilayered fabric mesh before water absorption.
[0124] Table 2: Data of air drag of multilayered fabric mesh / mesh substrate
[0125] Here, thickness (mm) refers to the thickness of a single layer (i.e., 1 layer) of mesh substrate. The unit of air volume is cubic meters per hour (m3 / h) . The unit of air drag is Pascal (Pa) .
[0126] Table 3: Data of humidification amount of multilayered fabric mesh / mesh substrate
[0127] Here, the temperature is measured in degrees Celsius (℃) . The humidity refers to relative humidity, which is the percentage of the vapor pressure in the air compared to the saturated vapor pressure at the same temperature. The humidification amount is measured in milliliters per hour (ml / h) .
[0128] The above description is only the preferred embodiments of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application shall fall within the scope of protection of the present application.
