Description

Technical Field

[0001] This application relates to the field of textile manufacturing technology, and in particular to a method, apparatus, system for manufacturing multi-band protective camouflage clothing, and multi-band protective camouflage clothing. Background Technology

[0002] Mainstream multi-band compatible camouflage technologies primarily achieve camouflage in the visible, near-infrared, and thermal infrared bands by coating or laminating materials with specific spectral characteristics onto the fabric surface. For example, near-infrared reflective pigments are added to simulate the "red-edge effect" of vegetation, while low-infrared emissivity coatings suppress thermal radiation signals. However, simulating the near-infrared "red-edge effect" of vegetation requires materials with high reflectivity in the 700-1100nm wavelength range, which fundamentally conflicts with the color absorption characteristics required for visible light camouflage and the low emissivity design for the thermal infrared band in terms of material spectral properties. Furthermore, the dense metallized coatings or films used to achieve low infrared emissivity severely sacrifice the fabric's breathability and moisture permeability.

[0003] Therefore, how to jointly improve the camouflage performance and wearing comfort of protective camouflage clothing has become a technical problem that this application urgently needs to solve. Summary of the Invention

[0004] The main objective of this application is to provide a method, apparatus, system for manufacturing multi-band protective camouflage clothing, and a multi-band protective camouflage clothing, aiming to solve the technical problem of how to jointly improve the camouflage performance and wearing comfort of protective camouflage clothing.

[0005] To achieve the above objectives, this application proposes a method for manufacturing a multi-band protective camouflage suit, the method comprising: A mesh-like base is prepared, and flexible camouflage elements with preset composite functions are fixed on the mesh-like base in an uneven cluster manner to obtain a three-dimensional breathable disturbance outer layer; A replaceable spectrally adapted middle layer is obtained by printing spectrally regulated functional dyeing materials onto a pre-set standard camouflage fabric. A passive thermal management inner layer is obtained by treating the pre-set basic functional fabric with low infrared emissivity. Combining the three-dimensional breathable disturbance outer layer, the replaceable spectral adaptation middle layer, and the passive thermal management inner layer yields a multi-band protective camouflage suit.

[0006] In one embodiment, the step of preparing a mesh-like substrate and fixing flexible camouflage elements with a preset composite function treatment on the mesh-like substrate in a non-uniform cluster manner to obtain a three-dimensional breathable disturbance outer layer includes: A mesh-like substrate is prepared based on a preset mesh size; The flexible camouflage element is impregnated or coated with an adhesive system containing functional fillers for composite functional treatment; The flexible camouflage elements after the composite function processing are clustered and mixed in an uneven manner or attached individually to the mesh-like base mesh to obtain the three-dimensional breathable disturbance outer layer.

[0007] In one embodiment, the flexible camouflage element includes natural fiber elements, artificial functional mesh strips, and a hybrid element that combines the natural fiber elements and the artificial functional mesh strips; the step of impregnating or coating the flexible camouflage element with an adhesive system containing functional fillers to perform a composite functional treatment includes: The natural fiber elements are drawn into sheets or filaments; Near-infrared shielding fabric strips or low-emissivity fabric strips are used as the artificial functional mesh fabric strips; The artificial functional mesh strips and natural fiber elements drawn into sheets or filaments are twisted or woven into composite strips to obtain the mixed elements; The artificial functional mesh strip, the mixed elements, and the natural fiber elements drawn into sheets or filaments are impregnated or coated with an adhesive system containing functional fillers. The adhesive system containing functional fillers includes near-infrared modulating materials and low emissivity functional materials.

[0008] In one embodiment, the step of printing a spectrally regulated functional dyeing material onto a preset standard camouflage fabric to obtain a replaceable spectrally adapted middle layer includes: Collect typical background spectral data from different combat areas, and design at least two contrasting color regions based on the typical background spectral data; The contrasting color regions are spectrally modulated to obtain daytime segmented colors and daytime blended colors; Based on the day-night perception, the grayscale relationship between the daytime segmented color and the daytime blended color is reversed to obtain the nighttime segmented color and the nighttime blended color; The functional dyeing material is prepared based on the daytime segmented color, the daytime blended color, the nighttime segmented color, and the nighttime blended color; The functional dyeing material is printed on the standard camouflage fabric to obtain a replaceable spectrally adapted middle layer.

[0009] In one embodiment, the step of performing low infrared emissivity treatment on a preset basic functional fabric to obtain a passive thermal management inner layer includes: A phase change material layer or a high thermal conductivity diffusion layer is composited onto the basic functional fabric to obtain the initial passive thermal management inner layer. The initial passive thermal management inner layer is processed using a double-layer mesh composite process to obtain a second passive thermal management inner layer; The passive thermal management inner layer is obtained by applying a low infrared emissivity coating to the surface of the second passive thermal management inner layer.

[0010] In one embodiment, the step of combining the three-dimensional breathable perturbation outer layer, the replaceable spectral-adaptive middle layer, and the passive thermal management inner layer to obtain a multi-band protective camouflage suit further includes: The three-dimensional breathable disturbance outer layer is trimmed and arranged, and a quick-disassembly connector is installed at a preset position on the three-dimensional breathable disturbance outer layer; The quick-detachable connector is installed in the middle layer of the replaceable spectral adapter; The quick-release connector is installed in the passive thermal management inner layer.

[0011] In one embodiment, the step of combining the three-dimensional breathable perturbation outer layer, the replaceable spectral-adaptive middle layer, and the passive thermal management inner layer to obtain a multi-band protective camouflage suit includes: Based on the quick-disassembly connectors, the three-dimensional breathable disturbance outer layer, the replaceable spectral adaptation middle layer, and the passive thermal management inner layer, a multi-band protective camouflage suit is obtained.

[0012] Furthermore, to achieve the above objectives, this application also proposes a multi-band protective camouflage clothing manufacturing apparatus, which includes: A three-dimensional breathable disturbance outer layer manufacturing module is used to prepare a mesh-like base mesh, and to fix flexible camouflage elements with preset composite functions in an uneven cluster manner on the mesh-like base mesh to obtain a three-dimensional breathable disturbance outer layer. A replaceable spectrally adapted mid-layer manufacturing module is used to print spectrally regulated functional dyeing materials on a preset standard camouflage fabric to obtain a replaceable spectrally adapted mid-layer. The passive thermal management inner layer manufacturing module is used to process the preset basic functional fabric with low infrared emissivity to obtain the passive thermal management inner layer. The combination module is used to combine the three-dimensional breathable disturbance outer layer, the replaceable spectral adaptation middle layer, and the passive thermal management inner layer to obtain a multi-band protective camouflage suit.

[0013] In addition, to achieve the above objectives, this application also proposes a multi-band protective camouflage clothing manufacturing system, the device comprising: a memory, a processor, and a computer program stored in the memory and executable on the processor, the computer program being configured to implement the steps of the multi-band protective camouflage clothing manufacturing method described above.

[0014] In addition, to achieve the above objectives, this application also provides a multi-band protective camouflage suit, which includes: a three-dimensional breathable disturbance outer layer, a replaceable spectral adaptation middle layer, and a passive thermal management inner layer.

[0015] One or more technical solutions proposed in this application have at least the following technical effects: First, the three-dimensional breathable disturbance outer layer, through its non-uniformly clustered and fixed flexible camouflage elements, simulates the complex spatial morphology and shadows of natural vegetation, disrupting the two-dimensional and three-dimensional outlines of the human body in the visible and near-infrared bands, thus enhancing camouflage performance. Furthermore, the airflow channels and thermal turbulence created by the three-dimensional structure promote heat and sweat dissipation, improving wearing comfort. Second, the replaceable spectrally adapted middle layer, through spectrally regulated functional dyeing materials, allows the camouflage pattern to effectively disrupt the target outline under both daytime visible light and nighttime low-light conditions, enhancing the camouflage effect. Additionally, the low infrared emissivity treatment of the passive thermal management inner layer suppresses thermal radiation signals, improving thermal infrared camouflage performance. Simultaneously, the high moisture-wicking and quick-drying properties of the basic functional fabric rapidly absorb and dissipate sweat, keeping the skin dry and improving wearing comfort. In summary, the combination of the three-dimensional breathable disturbance outer layer, the replaceable spectrally adapted middle layer, and the passive thermal management inner layer collectively enhances the camouflage performance and wearing comfort of the protective camouflage clothing.

[0019] The purpose, features, and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0020] It should be understood that the specific embodiments described herein are merely illustrative of the technical solutions of this application and are not intended to limit this application.

[0021] To better understand the technical solution of this application, a detailed description will be provided below in conjunction with the accompanying drawings and specific implementation methods.

[0022] The main solution of this application embodiment is as follows: a mesh-like base mesh is prepared, and flexible camouflage elements with preset composite functions are fixed on the mesh-like base mesh in a non-uniform cluster manner to obtain a three-dimensional breathable disturbance outer layer; a spectrally regulated functional dyeing material is printed on a preset standard camouflage clothing fabric to obtain a replaceable spectrally adapted middle layer; a preset basic functional fabric is treated with low infrared emissivity to obtain a passive thermal management inner layer; and the three-dimensional breathable disturbance outer layer, the replaceable spectrally adapted middle layer, and the passive thermal management inner layer are combined to obtain a multi-band protective camouflage clothing.

[0023] In this embodiment, for ease of description, the multi-band protective camouflage clothing manufacturing system will be used as the subject of the description.

[0024] This application's embodiments take into account that: Currently, with the rapid development of optoelectronic reconnaissance technology, single-band or simply layered camouflage clothing is no longer sufficient to cope with multi-spectral composite detection threats in complex battlefield environments. Modern soldiers face reconnaissance methods that have expanded from single visible light visual observation to a comprehensive system encompassing low-light night vision, thermal infrared imaging, and even radar detection. Therefore, multi-band compatible camouflage technology has emerged, but it still has a series of key shortcomings that urgently need to be addressed in terms of engineering and practical application, specifically as follows: First, existing technologies suffer from fundamental contradictions in multi-band performance coordination. For example, low-infrared emissivity materials, such as metallic coatings or composite materials, are commonly used to achieve thermal infrared camouflage. However, while low-emissivity coatings effectively suppress their own thermal radiation, they also reflect strong ambient infrared radiation (such as sunlight). Under thermal imagers, this can create a "thermal mirror" effect with a stark contrast to the low-temperature background, thus exposing the target. Simultaneously, to simulate the "red-edge effect" of vegetation in the near-infrared band, materials need high reflectivity in the 700-1100 nm range. This conflicts with the color absorption required for visible light camouflage and the low emissivity design for the thermal infrared band in terms of material spectral characteristics. Furthermore, reflectivity decreases at 1200 nm to accommodate water droplet reflection.

[0025] Secondly, existing solutions struggle to balance comfort and camouflage effectiveness, a trade-off particularly acute in tropical regions. To achieve low infrared emissivity, many technologies employ dense metallized coatings or films, severely sacrificing the fabric's breathability and moisture permeability. In the hot and humid tropical environment, soldiers wearing such camouflage clothing experience significant heat buildup due to the inability to dissipate heat and sweat, severely impacting their sustained combat capability and health. Furthermore, the elevated body surface temperature itself becomes a significant source of thermal infrared radiation, rendering the camouflage ineffective. In addition, traditional flat camouflage fabrics lack a three-dimensional structure, failing to simulate the complex spatial forms and shadows of natural backgrounds (such as bushes and grass), making them easily detectable under low-light night vision devices and side lighting due to unnatural light and shadow contours.

[0026] Therefore, this application provides a solution. First, through non-uniformly clustered and fixed flexible camouflage elements, the three-dimensional breathable disturbance outer layer can simulate the complex spatial morphology and shadows of natural vegetation, disrupting the two-dimensional and three-dimensional contours of the human body in the visible and near-infrared bands, thus improving camouflage performance. Furthermore, the airflow channels and thermal turbulence formed by the three-dimensional structure can promote heat and sweat dissipation, improving wearing comfort. Second, the replaceable spectrally adapted middle layer, through spectrally regulated functional dyeing materials, enables the camouflage pattern to effectively disrupt the target contours under both daytime visible light and nighttime low-light conditions, enhancing the camouflage effect. Additionally, the low infrared emissivity treatment of the passive thermal management inner layer can suppress thermal radiation signals, improving thermal infrared camouflage performance. Simultaneously, the high moisture-wicking and quick-drying properties of the basic functional fabric rapidly absorb and dissipate sweat, keeping the skin dry and improving wearing comfort. In summary, the combination of the three-dimensional breathable disturbance outer layer, the replaceable spectrally adapted middle layer, and the passive thermal management inner layer collectively improves the camouflage performance and wearing comfort of the protective camouflage clothing.

[0027] It should be noted that the executing entity in this embodiment can be a computing service device with data processing, network communication, and program execution functions, such as a tablet computer, personal computer, or mobile phone, or an electronic device capable of performing the above functions, a multi-band protective camouflage clothing manufacturing system, etc. The following description uses a multi-band protective camouflage clothing manufacturing system as an example to illustrate this embodiment and the subsequent embodiments.

[0028] Based on this, the embodiments of this application provide a method for manufacturing a multi-band protective camouflage suit, referring to... Figure 1 , Figure 1 This is a flowchart illustrating the first embodiment of the multi-band protective camouflage clothing manufacturing method of this application.

[0029] In this embodiment, the multi-band protective camouflage clothing manufacturing method includes steps S10 to S40: Step S10: Prepare a mesh-like base mesh, and fix flexible camouflage elements with preset composite functions on the mesh-like base mesh in an uneven cluster manner to obtain a three-dimensional breathable disturbance outer layer; By preparing a three-dimensional breathable disturbance outer layer, the human body contour can be physically broken, while achieving multi-band camouflage and passive thermal management. The three-dimensional structure of the three-dimensional breathable disturbance outer layer can not only destroy the two-dimensional and three-dimensional contours of the human body in the visible light and near-infrared bands, but also actively manage heat transfer through structural design, assisting in thermal infrared camouflage and improving the adaptability and wearing comfort of camouflage clothing in complex environments.

[0030] It should be noted that, in the embodiments of this application, the mesh-like base mesh refers to a fabric with a large mesh structure, which serves to provide a fixed carrier for flexible camouflage elements while ensuring the breathability of the camouflage clothing.

[0031] Flexible camouflage elements refer to flexible materials with camouflage functions, including natural fiber elements, artificial functional mesh strips, and mixed elements.

[0032] Preset composite function processing refers to the process of coating or impregnating a flexible camouflage element with a preset visible light color, a specific reflectivity in the 700-1100nm wavelength band, and a low infrared emissivity in the 8-14μm wavelength band by coating or impregnating it with an adhesive system containing functional fillers.

[0033] The non-uniform clustering method refers to fixing flexible camouflage elements in a non-uniform, clustered manner on a grid-like base network to form a loose, chaotic three-dimensional structure.

[0034] Specifically, the system first prepares a mesh-like base net, then fixes flexible camouflage elements, which have undergone preset composite function treatment, onto the mesh-like base net in a non-uniform cluster manner. The treated flexible camouflage elements, ranging in length from 5-15cm, are clustered together or individually bound, sewn, or adhered to the nodes of the mesh fabric, ensuring that the elements extend freely upwards and outwards in three-dimensional space, forming a fluffy, chaotic, three-dimensional cluster with a depth of 10-30cm. Finally, the outer layer of the finished product is finished by trimming excessively long fibers to obtain a three-dimensional, breathable, and perturbed outer layer.

[0035] Step S20: Print the spectrally regulated functional dyeing material on the preset standard camouflage fabric to obtain a replaceable spectrally adapted middle layer. By creating a replaceable spectrally adapted middle layer, day-night adaptive camouflage can be achieved, enabling the camouflage clothing to effectively disrupt target outlines and blend into the background under visible light during the day and low light conditions at night. At the same time, the replaceable design allows the camouflage clothing to be quickly adjusted according to different combat terrain backgrounds, improving the battlefield adaptability and logistical convenience of the camouflage clothing.

[0036] It should be noted that, in the embodiments of this application, the preset standard camouflage fabric refers to a basic camouflage fabric that meets certain standards and requirements and has good breathability and durability.

[0037] Spectral-modulated functional dyeing materials refer to inks containing specific near-infrared reflective pigments, which can be precisely controlled in terms of reflectivity in the visible light and 700-1100nm near-infrared bands.

[0038] The replaceable spectral-adaptive middle layer refers to the middle layer of the camouflage clothing that can be replaced according to combat needs. The color segmentation relationship of its camouflage pattern can be functionally reversed according to lighting conditions.

[0039] Specifically, the system first presets a standard camouflage fabric, then selects a spectrally regulated functional dyeing material to print camouflage patterns on the standard camouflage fabric. Using digital printing technology, a specially formulated functional dyeing material containing near-infrared reflective pigments is used to print camouflage patterns for different war zones on the standard camouflage fabric. The fabric is then cut and sewn into standardized middle-layer garment components with connectors, resulting in a replaceable spectrally adapted middle layer.

[0040] Step S30: The preset basic functional fabric is subjected to low infrared emissivity treatment to obtain a passive thermal management inner layer. By fabricating a passive thermal management inner layer, passive thermal management can be achieved close to the skin, creating stable surface conditions for thermal infrared camouflage and solving the problems of heat accumulation and unstable thermal signals in existing camouflage clothing. Furthermore, the low infrared emissivity treatment of the passive thermal management inner layer effectively suppresses its own thermal radiation, while its integrated passive thermal management technology can regulate body surface temperature, maintaining the long-term effectiveness of thermal infrared camouflage.

[0041] It should be noted that, in the embodiments of this application, the preset basic functional fabric refers to a functional fabric with high moisture wicking, quick drying and certain thermal conductivity, such as a fabric with added graphene fiber or cooling fiber.

[0042] Low infrared emissivity treatment refers to the process of applying or impregnating a fabric with a coating containing low infrared emissivity fillers to give the fabric a lower emissivity in the 8-14μm wavelength band.

[0043] Passive thermal management inner layer refers to the inner layer of camouflage clothing that is close to the skin. Its core task is to manage body heat passively and create stable surface conditions for thermal infrared camouflage.

[0044] Specifically, the system coats the outer surface (the side facing the middle layer) of the basic functional fabric with a coating containing a low infrared emissivity filler, either wholly or partially, and then dries and sets the coating. Simultaneously, a phase change material layer or a high thermal conductivity diffusion layer is laminated onto the basic underwear fabric, and a structural heat dissipation zone is formed using a double-layer mesh composite process. Finally, the fabric is cut and sewn into an inner garment assembly with connectors, resulting in a passive thermal management inner layer.

[0045] Step S40: Combine the three-dimensional breathable disturbance outer layer, the replaceable spectral adaptation middle layer, and the passive thermal management inner layer to obtain a multi-band protective camouflage suit.

[0046] The system combines a three-dimensional breathable disturbance outer layer, a replaceable spectral-adaptive middle layer, and a passive thermal management inner layer. Specifically, users can first wear the passive thermal management inner layer according to mission requirements, then secure the selected replaceable spectral-adaptive middle layer to the passive thermal management inner layer using quick-release buckles, and finally drape the three-dimensional breathable disturbance outer layer and secure it to the replaceable spectral-adaptive middle layer using quick-release buckles and an emergency drawcord system, thus completing the combination of the complete multi-band protective camouflage suit.

[0047] This embodiment provides a method for manufacturing multi-band protective camouflage clothing. Through non-uniformly clustered, fixed flexible camouflage elements, the three-dimensional breathable disturbance outer layer can simulate the complex spatial morphology and shadows of natural vegetation, disrupting the two-dimensional and three-dimensional outlines of the human body in the visible and near-infrared bands, thus improving camouflage performance. Furthermore, the air circulation channels and thermal turbulence formed by the three-dimensional structure can promote heat and sweat dissipation, improving wearing comfort. Secondly, the replaceable spectrally adapted middle layer, through spectrally regulated functional dyeing materials, enables the camouflage pattern to effectively disrupt the target outline under both daytime visible light and nighttime low-light conditions, enhancing the camouflage effect. Additionally, the low infrared emissivity treatment of the passive thermal management inner layer can suppress thermal radiation signals, improving thermal infrared camouflage performance. Simultaneously, the high moisture-wicking and quick-drying properties of the basic functional fabric rapidly absorb and dissipate sweat, keeping the skin dry and improving wearing comfort. In summary, the combination of the three-dimensional breathable disturbance outer layer, the replaceable spectrally adapted middle layer, and the passive thermal management inner layer collectively improves the camouflage performance and wearing comfort of the protective camouflage clothing.

[0048] Based on the first embodiment of this application, a second embodiment of this application is proposed. In the second embodiment of this application, content that is the same as or similar to that in the first embodiment described above can be referred to the above description and will not be repeated hereafter.

[0049] Based on this, please refer to Figure 2 , Figure 2 This is a flowchart illustrating the second embodiment of this application, as shown below. Figure 2As shown, step S10, which involves preparing a mesh-like substrate and fixing flexible camouflage elements with a pre-defined composite function to the mesh-like substrate in a non-uniform clustered manner to obtain a three-dimensional breathable permeable outer layer, may include steps S11 to S13: Step S11: Prepare a mesh-like substrate mesh based on a preset mesh size; It should be noted that, in this embodiment, the preset mesh size refers to the mesh size of the grid-like base fabric pre-set according to the usage scenario and performance requirements of the camouflage clothing. A suitable mesh size allows flexible camouflage elements to be better fixed on the base fabric, while providing sufficient space for air circulation, thereby improving the heat dissipation performance and camouflage effect of the camouflage clothing.

[0050] In one possible implementation, the preset mesh size can be adjusted according to different operational environments. For example, in tropical jungle environments, to ensure better breathability and heat dissipation, the preset mesh size can be set to 10-15cm; in temperate grassland environments, the preset mesh size can be set to 8-12cm. The mesh base can be made of large-mesh synthetic fiber or blended mesh fabric, which has good abrasion resistance and corrosion resistance.

[0051] Specifically, the system first determines the preset mesh size based on the combat environment, then selects a suitable fabric material and prepares a mesh-like base net with that mesh size through weaving or cutting. During the preparation process, it is necessary to ensure the uniformity of the mesh and the overall strength of the base fabric.

[0052] Step S12: Impregnate or coat the flexible camouflage element with an impregnating material or adhesive system containing functional fillers to perform composite functional treatment. It should be noted that, in the embodiments of this application, the impregnation or adhesive system containing functional fillers refers to the impregnation material and adhesive system containing functional fillers such as near-infrared modulation materials and low emissivity functional materials, the function of which is to enable the flexible camouflage element to obtain specific spectral characteristics.

[0053] Multifunctional treatment refers to the process of enabling flexible camouflage elements to possess multiple functions simultaneously by impregnating or coating them with an adhesive system containing functional fillers.

[0054] In one possible implementation, the near-infrared modulating material in the adhesive system containing functional fillers can be titanium dioxide (TiO2), chromium oxide, indium oxide (ITO) with special surface coating treatment, etc., and the low emissivity functional material can be sheet-like aluminum powder, modified graphene, lanthanum hexaboride (LaB6) ultrafine powder, etc. The flexible camouflage element can be sheet-like or filamentous materials made of jute or sisal filaments, raffia or mesh strips, near-infrared resistant strips with specific near-infrared reflectance spectra, low-emissivity strips with low infrared emissivity, and composite strips formed by twisting or weaving natural fibers and functional strips together, etc.

[0055] The system impregnates or coats flexible camouflage elements with an adhesive system containing functional fillers for composite functionalization. Specifically, the system first prepares an impregnating material or adhesive system containing functional fillers, then impregnates the flexible camouflage element into the impregnating material or adhesive system, or coats the surface of the flexible camouflage element with the impregnating material or adhesive. After processing, the flexible camouflage element is dried and set to obtain the preset spectral characteristics.

[0056] Step S13: The flexible camouflage elements after the composite function processing are clustered and mixed in an uneven manner or attached individually to the mesh-like base mesh to obtain the three-dimensional breathable disturbance outer layer.

[0057] It should be noted that, in the embodiments of this application, "non-uniform method" refers to mixing flexible camouflage elements on a mesh-like base network in a non-uniform, clustered, or individual manner. Clustered mixing refers to mixing multiple flexible camouflage elements together to form a cluster, which is then fixed to the mesh-like base network. Individual attachment refers to directly fixing a single flexible camouflage element to the mesh-like base network.

[0058] In one possible implementation, the system can use automated or semi-automatic equipment to non-uniformly cluster and individually attach flexible camouflage elements, after composite functional processing, to a mesh-like base network. For example, a robotic arm can be used to randomly place the flexible camouflage elements on the mesh-like base network, and then secure them by binding, stitching, or adhesive. During the mixing process, the type, color, and mixing ratio of the flexible camouflage elements can be adjusted according to different operational environments and camouflage requirements.

[0059] Additionally, it should be noted that the system non-uniformly clusters or individually attaches the composite-processed flexible camouflage elements to the grid-like base mesh. Specifically, the system first classifies and organizes the composite-processed flexible camouflage elements, and then uses automatic or semi-automatic equipment to non-uniformly cluster or individually attach them to the nodes of the grid-like base mesh. During the mixing process, the flexible camouflage elements are ensured to extend freely upwards and outwards in three-dimensional space, forming fluffy, disordered, three-dimensional clusters with a depth of 10-30cm. Finally, the outer layer of the finished product is finished, and excessively long fibers are trimmed to obtain a three-dimensional, breathable, and perturbed outer layer.

[0060] In this embodiment, a mesh-like base with a preset mesh size provides a stable and breathable support for the flexible camouflage elements. The flexible camouflage elements, processed with composite functions, possess visible light mimicry, near-infrared spectral matching, and low thermal infrared radiation characteristics. Furthermore, through a non-uniform, random, clustered fixing method, a loose and chaotic three-dimensional structure is formed. This series of operations not only completely disrupts the regular contours of the human body, achieving deep integration with the natural background in the visible and near-infrared bands, but also effectively solves the problem of heat accumulation in low-emissivity materials by utilizing the thermal turbulence and air convection channels generated by the three-dimensional structure. Simultaneously, it achieves the dual effectiveness of multi-band camouflage and passive thermal management, significantly improving the concealment and wearing comfort of the camouflage clothing in complex battlefield environments.

[0061] In one feasible implementation, step S12 may include steps S121 to S124: Step S121: The natural fiber element is drawn into sheets or filaments; By drawing natural fiber elements into sheets or filaments, their surface area can be increased, allowing for better absorption of impregnating materials or adhesive systems containing functional fillers, thus enhancing the effectiveness of composite functional treatments. Furthermore, sheet or filament-shaped natural fiber elements can better mimic the morphology of natural vegetation, enhancing the camouflage effect of the camouflage clothing. Simultaneously, when sheet or filament-shaped natural fiber elements are fixed to a mesh-like base, they can form a more fluffy, irregular three-dimensional structure, improving the breathability and heat dissipation of the camouflage clothing.

[0062] It should be noted that, in the embodiments of this application, natural fiber elements refer to fiber materials extracted from natural plants, such as jute, sisal, and raffia. Drawing into sheets or filaments refers to processing natural fiber elements into sheet or filament form through processes such as stretching and cutting.

[0063] In one possible implementation, the system can use mechanical stretching to draw natural fiber elements into sheets or filaments. For example, a filament-drawing machine can be used to draw jute fiber bundles into filaments, while high-temperature pressing can be used to press raffia into sheets. During the drawing process, the thickness and width of the sheets or filaments can be adjusted as needed to meet different camouflage requirements.

[0064] Step S122: Use near-infrared shielding fabric strips or low emissivity fabric strips as the artificial functional mesh fabric strips; It should be noted that, in the embodiments of this application, the near-infrared protection strip refers to a strip of fabric that has undergone special treatment and has high reflectivity in the 700-1100nm near-infrared band. The low emissivity strip refers to a strip of fabric that has undergone special treatment and has low emissivity in the 8-14μm thermal infrared band. The artificial functional mesh strip refers to an artificial fabric strip with specific functions, used to improve the multi-band camouflage performance of the camouflage clothing.

[0065] In one possible implementation, the near-infrared shielding strip can be a polyester fiber strip containing near-infrared reflective pigments. These pigments can be titanium dioxide (TiO2), chromium oxide, indium oxide (ITO) with special surface coating treatment, etc. The low-emissivity strip can be a nylon strip containing low-infrared emissivity fillers. These fillers can be flake aluminum powder, modified graphene, lanthanum hexaboride (LaB6) ultrafine powder, etc.

[0066] Specifically, the system selects appropriate near-infrared resistant or low-emissivity fabric strips as artificial functional mesh strips based on the usage scenario and performance requirements of the camouflage suit. During the selection process, parameters such as the fabric's color, material, reflectivity, or emissivity need to be considered to ensure that it meets the multi-band camouflage requirements of the camouflage suit.

[0067] Step S123: The artificial functional mesh strip and the natural fiber elements drawn into sheets or filaments are twisted or woven into a composite strip to obtain the mixed elements; In one possible implementation, the system can create composite strips by mechanically twisting or weaving artificial functional mesh strips and natural fiber elements drawn into sheets or filaments. For example, the artificial functional mesh strips and natural fiber elements can be twisted together using a twisting machine, or woven into strips using a weaving machine or by hand. During the twisting or weaving process, the proportion and arrangement of the artificial functional mesh strips and natural fiber elements can be adjusted according to different camouflage requirements.

[0068] Step S124: Impregnate or coat the artificial functional mesh strip, the mixed elements, and the natural fiber elements drawn into sheets or filaments with an adhesive system containing functional fillers. The adhesive system containing functional fillers includes near-infrared modulating materials and low emissivity functional materials.

[0069] The system can select appropriate impregnation or coating methods based on the characteristics of different flexible camouflage elements. For artificial functional mesh strips and hybrid elements, impregnation can be used to ensure full absorption of the adhesive system containing functional fillers; for natural fiber elements drawn into sheets or filaments, coating can be used to evenly apply the impregnating material or adhesive to their surface. During the impregnation or coating process, it is necessary to control the concentration and temperature of the impregnating material or adhesive to ensure that the flexible camouflage elements obtain a uniform coating and good spectral characteristics.

[0070] Based on the first and / or second embodiments of this application, a third embodiment of this application is proposed. In the third embodiment of this application, content that is the same as or similar to the first and / or second embodiments described above can be referred to the above description and will not be repeated hereafter.

[0071] Based on this, please refer to Figure 3 , Figure 3 This is a schematic diagram of the process of the third embodiment of this application, as shown below. Figure 3 As shown, in this embodiment, step S20, which involves printing a spectrally regulated functional dyeing material onto a preset standard camouflage fabric to obtain a replaceable spectrally adapted middle layer, may include steps S21 to S25: Step S21: Collect typical background spectral data of different combat areas, and design at least two contrasting color regions based on the typical background spectral data; It should be noted that, in the embodiments of this application, different combat areas refer to combat zones with different natural environmental characteristics, including temperate jungles, tropical deserts, and cold grasslands.

[0072] Typical background spectral data refers to the data obtained by spectral measurement of representative natural backgrounds (such as vegetation, soil, rocks, etc.) in different combat areas, reflecting the reflectivity characteristics of the background at different wavelengths.

[0073] Contrast color areas refer to color areas that differ in hue, brightness, or saturation under visible light, used to disrupt the outline of a target and achieve a camouflage effect.

[0074] In one possible implementation, a spectrometer can be used to collect spectral data in typical background areas of different operational zones. The collection time can be selected under different lighting conditions, such as sunny days, cloudy days, early morning, and evening, to obtain more comprehensive background spectral data. Based on the collected spectral data, at least two contrasting color regions are designed using data analysis and image processing software. The selection of color regions can be adjusted according to the main color characteristics of the background.

[0075] Step S22: Perform spectral modulation on the contrasting color regions to obtain daytime segmented colors and daytime blended colors; It should be noted that, in the embodiments of this application, spectral modulation refers to changing the reflectivity characteristics of a color region at different wavelengths by adjusting the composition and structure of the color region, so as to achieve the preset spectral requirements.

[0076] Daytime segmentation color refers to a color that contrasts sharply with the background under visible daylight conditions, used to disrupt the outline of a target.

[0077] Daytime blending color refers to a color that blends with the average hue of the background under daytime visible light conditions, reducing the visibility of the target.

[0078] In one possible implementation, the system can perform spectral modulation by adding different types and amounts of pigments or dyes to the color regions. For example, for daytime blending colors, pigments similar to the background color can be added, and their amounts adjusted so that the reflectivity of the color region under visible light matches the background; for daytime segmentation colors, pigments with significantly different background colors can be added to create a clear contrast. Simultaneously, the spectral characteristics can be further adjusted by changing the surface structure of the color regions, such as by employing texturing.

[0079] Specifically, the system determines the target reflectance of daytime segmentation colors and daytime blending colors under visible light based on collected typical background spectral data. Then, by adding specific pigments or dyes to the contrasting color regions and adjusting their content and proportions, the system performs spectral modulation on the color regions. For daytime blending colors, the reflectance under visible light is made similar to the average reflectance of the background to achieve fusion with the background; for daytime segmentation colors, the reflectance under visible light is made to create a clear contrast with the background, disrupting the target outline. Finally, the spectral measurements of the modulated color regions are performed to verify whether they meet the preset spectral requirements.

[0080] Step S23: Based on day and night perception, reverse the grayscale relationship between the daytime segmented color and the daytime blended color to obtain the nighttime segmented color and the nighttime blended color; Specifically, reversing the grayscale relationship between the daytime segmented color and the daytime blended color based on day and night perception refers to adjusting the near-infrared reflectivity of the daytime segmented color and the daytime blended color to reverse their grayscale relationship and obtain the nighttime segmented color and the nighttime blended color.

[0081] In one possible implementation, the system can adjust the near-infrared reflectivity of the daytime segmented color and the daytime blended color by adding near-infrared reflective pigments or adjusting the pigment content. For example, for the nighttime blended color, a pigment with high near-infrared reflectivity can be added to increase its reflectivity in the near-infrared band, resulting in a brighter grayscale under low-light night vision equipment, thus becoming the nighttime blended color. Without the addition of pigments with high near-infrared reflectivity, the reflectivity in the near-infrared band is generally lower, resulting in a darker grayscale under low-light night vision equipment, thus becoming the nighttime segmented color.

[0082] Additionally, it should be noted that the system determines the target reflectance of the nighttime segmented color and the nighttime blended color in the near-infrared band based on the spectral characteristics of the nighttime background and the working principle of the low-light night vision equipment. Then, by adding specific near-infrared reflective pigments or adjusting the pigment content in the daytime segmented color and the daytime blended color, their near-infrared reflectance is adjusted. This reduces the reflectance of the daytime segmented color in the near-infrared band, making it appear as a relatively dark gray under low-light night vision equipment, thus becoming the nighttime segmented color; and it deviates the spectrum of the daytime segmented color in the near-infrared band from the color of green vegetation, making it the daytime blended color, thereby reversing their grayscale relationship. Finally, near-infrared spectral measurements and low-light night vision equipment observations are performed on the adjusted color areas to verify whether they achieve the preset nighttime camouflage effect.

[0083] Step S24: Prepare the functional dyeing material based on the daytime segmented color, the daytime blended color, the nighttime segmented color, and the nighttime blended color; In one possible implementation, the system can select appropriate raw materials such as pigments, resins, and solvents to prepare functional dyeing materials based on the spectral characteristics of daytime segmented colors, daytime blended colors, nighttime segmented colors, and nighttime blended colors. For example, for colors requiring high near-infrared reflectivity, raw materials containing near-infrared reflective pigments can be selected; for colors requiring low near-infrared reflectivity, raw materials containing light-absorbing pigments can be selected. During the preparation process, the proportions and mixing methods of the raw materials are adjusted to ensure that the functional dyeing material meets the preset spectral requirements.

[0084] Step S25: Print the functional dyeing material on the standard camouflage fabric to obtain a replaceable spectral-adaptive middle layer.

[0085] Digital printing technology is used to print functional dyeing materials onto standard camouflage fabrics. Digital printing is characterized by high precision and flexibility, allowing for the rapid production of camouflage patterns tailored to different operational areas and camouflage requirements. During the printing process, printing parameters such as nozzle height, printing speed, and ink volume can be adjusted to ensure the printing quality and spectral characteristics of the functional dyeing materials on the fabric.

[0086] In this embodiment, by collecting typical background spectral data of different combat areas and designing contrasting color regions, the adaptation benchmark of camouflage clothing to the environment is accurately anchored; the daytime and nighttime segmented colors and fusion colors are obtained through spectral modulation, realizing the precise switching of daytime and nighttime camouflage logic; functional dyeing materials endow the camouflage pattern with multi-band spectral response capabilities; thereby greatly improving the camouflage clothing's all-time and all-area concealment capabilities and operational flexibility in complex battlefield environments.

[0087] Based on the above embodiments of this application, a fourth embodiment of this application is proposed. In this fourth embodiment, content that is the same as or similar to that in the above embodiments can be referred to the above description, and will not be repeated hereafter.

[0088] In this embodiment, step S30, which involves processing the preset basic functional fabric with low infrared emissivity to obtain a passive thermal management inner layer, may include steps S31 to S33: Step S31: Composite a phase change material layer or a high thermal conductivity diffusion layer onto the basic functional fabric to obtain the initial passive thermal management inner layer. The system first selects a suitable basic functional fabric according to design requirements, then encapsulates phase change material microcapsules within the fabric interlayer to form a phase change material layer; alternatively, it laminates or weaves materials with high thermal conductivity in areas prone to heat accumulation to form a high thermal conductivity diffusion layer. During the lamination process, it ensures a strong bond between the phase change material layer or the high thermal conductivity diffusion layer and the basic functional fabric, without affecting the fabric's breathability and comfort. Finally, the laminated fabric undergoes quality testing, such as measuring the phase change temperature of the phase change material and the thermal conductivity of the high thermal conductivity diffusion layer, to ensure it meets the preset performance requirements, thus obtaining the initial passive thermal management inner layer.

[0089] In one possible implementation, the system can employ a hot melt adhesive lamination process to laminate the phase change material layer onto the base functional fabric. Phase change material microcapsules are uniformly distributed within the hot melt adhesive, which is then heated to melt and bond the phase change material layer to the base functional fabric. For the high thermal conductivity diffusion layer, a weaving process can be used to weave carbon fiber yarns into the heat-accumulating areas of the base functional fabric, forming a high thermal conductivity diffusion structure.

[0090] Step S32: The initial passive thermal management inner layer is processed using a double-layer mesh composite process to obtain the second passive thermal management inner layer; The system places the initial passive thermal management inner layer between two pre-prepared layers of mesh fabric, with the mesh nodes of the two layers staggered. Then, the two mesh layers are bonded together with the initial passive thermal management inner layer using processes such as sewing or bonding, forming a stable air gap. During the bonding process, the thickness of the air gap is ensured to be uniform, so as not to affect the function of the phase change material layer or high thermal conductivity diffusion layer of the initial passive thermal management inner layer. Finally, the breathability of the bonded fabric is tested to ensure that it meets the preset breathability requirements, resulting in the second passive thermal management inner layer.

[0091] In one possible implementation, the system can employ an ultrasonic stitching process to laminate two layers of mesh fabric. The mesh nodes of the two layers are aligned in an alternating pattern, and ultrasonic vibration melts and bonds the contact surfaces of the mesh fabric together, forming a stable air gap. During the lamination process, the density and strength of the stitching are controlled to ensure the stability and breathability of the air gap.

[0092] Step S33: Apply a low infrared emissivity coating to the surface of the second passive thermal management inner layer to obtain the passive thermal management inner layer.

[0093] The system first fixes the second passive thermal management inner layer onto the spraying equipment, and cleans and pre-treats the surface to be treated to ensure it is clean and smooth. Then, a low-infrared emissivity material is mixed with an adhesive to form a coating solution, which is then uniformly sprayed onto the surface using the spraying equipment, controlling the coating thickness to be between 10-20 μm. After spraying, the second passive thermal management inner layer is dried and cured to ensure the coating adheres firmly to the surface. Finally, the treated inner layer undergoes a low-infrared emissivity test to ensure its emissivity in the 8-14 μm wavelength band is below 0.5, thus obtaining the passive thermal management inner layer.

[0094] In one possible implementation, the system can employ a spraying process to apply a low-infrared emissivity coating. Low-infrared emissivity materials (such as flake aluminum powder, modified graphene, lanthanum hexaboride ultrafine powder, etc.) are mixed with an adhesive to form a coating solution. This coating solution is then uniformly sprayed onto the surface of the second passive thermal management inner layer using a spraying device. During the spraying process, the thickness and uniformity of the coating are controlled to ensure its low-infrared emissivity performance.

[0095] In this embodiment, a phase change material layer or a high thermal conductivity diffusion layer is composited onto the basic functional fabric, laying the foundation for passive thermal management and enabling heat storage and rapid diffusion. The double-layer mesh composite process further optimizes thermal management performance, promoting micro-air circulation through air gaps and preventing the formation of enclosed heat zones. A low infrared emissivity coating treatment endows the inner layer with excellent thermal infrared camouflage performance, working in conjunction with the middle layer to form a controllable thermal radiation surface. This significantly enhances the camouflage clothing's concealment capability in the thermal infrared band.

[0096] Based on the above embodiments of this application, a fifth embodiment of this application is proposed. In this fifth embodiment, content that is the same as or similar to that in the above embodiments can be referred to the above description, and will not be repeated hereafter.

[0097] Based on this, please refer to Figure 4 , Figure 4 This is a schematic flowchart of the fifth embodiment of this application, as shown below. Figure 4 As shown, before step S40, which combines the three-dimensional breathable disturbance outer layer, the replaceable spectral adaptation middle layer, and the passive thermal management inner layer to obtain a multi-band protective camouflage suit, steps S01 to S03 are also included: Step S01: Trim and arrange the three-dimensional breathable disturbance outer layer, and install a quick-disassembly connector at a preset position on the three-dimensional breathable disturbance outer layer; The system first inspects the three-dimensional breathable disturbance outer layer, trimming excessively long camouflage elements to maintain the length of the three-dimensional clusters between 5-15cm and the depth between 10-30cm, enhancing the camouflage effect. Then, quick-release connectors are installed at predetermined locations such as the shoulders, waist, and main seams of the three-dimensional breathable disturbance outer layer using sewing or gluing methods. During installation, it is ensured that the connectors are securely installed without affecting the breathability and camouflage performance of the three-dimensional breathable disturbance outer layer. Finally, functional tests are performed on the three-dimensional breathable disturbance outer layer with the connectors installed, such as testing the connection strength and quick-release performance of the connectors, to ensure that they meet the preset requirements.

[0098] In one possible implementation, the system can employ laser trimming technology to prune and refine the outer layer of the three-dimensional breathable disturbance. By precisely cutting excessively long camouflage elements with a laser, the three-dimensional clusters become more regular or conform to the interlacing characteristics of natural vegetation. For the installation of quick-release connectors, a sewing process can be used to sew a composite quick-release system integrating quick-connect buckles and emergency pull ropes to preset positions on the outer layer of the three-dimensional breathable disturbance, ensuring a secure connection and convenient operation.

[0099] Step S02: Install the quick-detachable connector in the middle layer of the replaceable spectral adapter; The system first determines the installation position on the replaceable spectral adapter middle layer based on the location of the quick-release connectors on the three-dimensional breathable disturbance outer layer and the passive thermal management inner layer. Then, suitable quick-release connectors are selected and installed in the corresponding positions on the replaceable spectral adapter middle layer by means of sewing, gluing, or heat pressing.

[0100] Step S03: Install the quick-disassembly connector on the passive thermal management inner layer.

[0101] The system first determines the installation position on the passive thermal management inner layer based on the location of the quick-release connectors on the three-dimensional breathable disturbance outer layer and the replaceable spectral adaptation middle layer. Then, suitable quick-release connectors are selected and installed in the corresponding positions on the passive thermal management inner layer by means of sewing, welding, or gluing.

[0102] In this embodiment, by installing quick-disassembly connectors on the three-dimensional breathable disturbance outer layer, the replaceable spectral adaptation middle layer, and the passive thermal management inner layer, the rapid combination and separation of the various layers of the camouflage suit can be achieved, facilitating both combined and independent use.

[0103] In one possible implementation, step S40 may include step S41: Step S41: Based on the quick-disassembly connector, the three-dimensional breathable disturbance outer layer, the replaceable spectral adaptation middle layer, and the passive thermal management inner layer are combined to obtain a multi-band protective camouflage suit.

[0104] For example, the soldier first wears the passive thermal management inner layer, then combines the replaceable spectral-adaptive middle layer with the passive thermal management inner layer via quick-release connectors, ensuring that the camouflage pattern of the middle layer matches the background of the combat area. Finally, the three-dimensional breathable disturbance outer layer is combined with the replaceable spectral-adaptive middle layer via quick-release connectors, allowing the three-dimensional clusters to extend freely upwards and outwards, forming a fluffy, messy three-dimensional structure.
