Description

Technical Field

[0001] This invention belongs to the field of special clothing technology, specifically relating to a thermal infrared camouflage garment and its design method. Background Technology

[0002] Traditional individual camouflage uniforms are insufficient to meet the needs of modern warfare for individual soldier concealment, especially with the development of infrared thermal radiation reconnaissance technology based on thermal infrared imagers, posing a significant challenge to the survival of individual soldiers on the battlefield. Due to human body temperature, infrared radiation is continuously emitted, resulting in high levels of infrared thermal radiation. Based on wavelength range, the infrared band can be subdivided into near-infrared (NIR, 0.76–1.5 μm), short-wave infrared (SWIR, 1.5–3 μm), mid-wave infrared (MWIR, 3–8 μm), long-wave infrared (LWIR, 8–15 μm), and far-infrared (FIR, 15–1000 μm). Most of the infrared radiation emitted by the human body is absorbed by the atmosphere and dissipated. However, due to the existence of two natural atmospheric windows (3–5 μm and 8–14 μm), infrared radiation in these two bands can be radiated into outer space with minimal loss. Thermal infrared imagers utilize these atmospheric windows, precisely adjusting their detection band to these two atmospheric window ranges to achieve infrared reconnaissance. Because thermal infrared imagers are almost unaffected by weather and can work normally both day and night, they can accurately detect the precise location of the human body. Compared with visible light camouflage, thermal infrared camouflage is more difficult to protect against.

[0003] Thermal infrared camouflage clothing works by actively reducing the intensity of the human body's external thermal radiation, making the human body's thermal radiation more consistent with the environment, thus effectively blending into the environment and evading detection by infrared thermal imagers. CN219757119U discloses a thermal infrared camouflage clothing. This technical solution consists of the clothing body, a hood, and a camouflage curtain. It reduces human body thermal radiation by using low infrared emissivity fabric, employs a camouflage curtain, and uses a one-piece fabric between the body and sleeves to reduce the visibility of the human body's outline, thereby achieving individual soldier thermal infrared camouflage stealth. However, it has at least three drawbacks:

[0004] (1) All clothing fabrics are made of low infrared emissivity fabrics, which are only suitable for scenes with low ambient temperature. Once the surrounding environment is temperate or tropical, the ambient temperature is high and the thermal radiation is high, while the soldiers wearing the camouflage clothing have low thermal radiation. Therefore, the soldiers wearing the camouflage clothing will be more obviously different from the environment in the thermal infrared imager and will be easier to detect.

[0005] (2) Insufficient practicality of the clothing structure. In order to reduce the visibility of the human body silhouette, the body and sleeves are made of one-piece fabric, and a camouflage curtain is added to the back of the clothing. Such a design can reduce the human body silhouette to a certain extent, but in the actual combat environment of a single soldier, the one-piece fabric structure will greatly restrict the soldier's tactical operation, and the design of the camouflage curtain will increase the risk of the clothing getting caught in the complex surrounding environment, and will also restrict the soldier's rapid march.

[0006] (3) The visible light camouflage effect of the clothing is insufficient. Although the use of one-piece fabric and camouflage curtain design can reduce the outline of the human body to a certain extent in the detection of thermal infrared imagers, this irregular structure actually increases the risk of visible light detection. Under visual detection with a telescope, any irregular structure will increase the probability of being detected. Summary of the Invention

[0054] Some embodiments disclose design methods for thermal infrared camouflage clothing, including:

[0055] Human body thermal distribution modeling and distribution design, specifically including:

[0056] A database of human infrared thermal distribution is established by measuring the surface temperature distribution of people using an infrared thermal imager.

[0057] Based on the human body thermal infrared distribution database, the human body is divided into three thermal functional zones; among them, the core trunk, armpits, and head are high-heat zones, the proximal extremities are medium-heat zones, and the distal extremities and clothing edges are low-heat zones.

[0062] Some embodiments disclose a design method for thermal infrared camouflage clothing, which also includes the design of a detachable 3D camouflage net integrated module, specifically including: designing a fixing connecting loop on the outer surface of the infrared camouflage clothing; making the 3D camouflage net module using materials that are compatible with the environment; and fixing the 3D camouflage net module using the connecting loop.

[0063] The technical details are further illustrated below with reference to the embodiments.

[0064] Example 1

[0065] In Example 1, the design method for thermal infrared camouflage clothing includes:

[0066] Step 1: Human Body Thermal Distribution Modeling and Zoning Design

[0067] A "human infrared thermal distribution database" was established by measuring the surface temperature distribution of a large number of people in typical environments and under different activity states using infrared thermal imagers. Based on the database, the main trunk and limbs of the human body were divided into multiple thermal functional zones. For example, they can be divided into three thermal functional zones: high-temperature zone, medium-temperature zone, and low-temperature zone. The high-temperature zone includes the core trunk, armpits, and head; the medium-temperature zone includes the proximal extremities; and the low-temperature zone includes the distal extremities and clothing edges.

[0068] Step 2: Preparation and stitching of gradient infrared emissivity fabric

[0069] Fabric base material selection: Select textile fabrics with good durability, breathability and certain heat insulation properties, such as aramid, nylon and polyester-cotton blended fabrics as base materials.

[0070] Emissivity modulation treatment: Functional layers with different infrared emissivity ε are prepared on the substrate using coating, film deposition, or composite processes. At least three key fabrics are prepared: a low emissivity fabric with ε≤0.3, used to simulate low-temperature backgrounds and suppress radiation from high-temperature areas; a medium emissivity fabric with 0.3<ε≤0.7, used to simulate common backgrounds such as vegetation and soil; and a high emissivity fabric with 0.7<ε≤0.95, used to simulate objects close to ambient temperature or to achieve dynamic adjustment.

[0071] Gradient seam design: Based on the thermal functional zoning design in step one, fabrics with different emissivity are cut into irregularly shaped pieces and sewn together: the lowest emissivity fabric is used in the center of the high-heat zone, transitioning outwards with medium emissivity fabric; medium emissivity fabric is mainly used in the medium-heat zone, gradually transitioning with the fabrics of adjacent high and low heat zones; in the low-heat zone and at the edges of the garment outline, high emissivity fabric or the emissivity fabric that best matches the environment is used, so that the thermal outline of the human body transitions naturally with the background, achieving an edge melting effect.

[0072] Step 3: Design of Detachable 3D Camouflage Net Integrated Module

[0073] Modular design: The outer surface of the gradient infrared camouflage suit made in step two is designed with fixed connecting loops to fix the 3D camouflage net module.

[0074] 3D camouflage net module: Made of materials that match the environment, such as imitation leaves, grass clumps, and scraps of cloth, the 3D camouflage net module has visible light color and near-infrared reflective properties similar to natural vegetation.

[0075] like Figure 1 The diagram shown is a schematic of the thermal infrared camouflage clothing designed in Example 1. The clothing includes a top and trousers. Figure 1 In the image, the left image shows the front of the garment, the middle image shows the back of the garment, and the right image shows the visual effect of the 3D camouflage net module fixedly connected to the back of the garment.

[0076] Example 2

[0077] In Example 2, the design of the thermal infrared camouflage suit includes:

[0078] A thermal infrared camouflage suit was designed using the design method disclosed in Example 1.

[0079] The garment is constructed from three types of emissivity fabrics. The low and medium emissivity areas utilize a functional fabric coating with low ε=0.1 and medium ε=0.5, while the high emissivity areas use a multi-terrain camouflage fabric with high ε=0.9. This combination of functional and camouflage fabrics achieves a multi-dimensional camouflage effect for the product.

[0080] The clothing features a two-piece design, including a spliced ​​top and trousers. The top consists of a connected body and sleeves; a hood is attached to the top of the body. The hood can be integrated with a camouflage mask via snaps. The mask is made of high-performance infrared-resistant stealth fabric, with laser-drilled holes designed to ensure that the infrared-resistant material's performance is not compromised while maintaining the wearer's vision. The mask is detachable and can be folded away when not in use, providing enhanced camouflage for the face. Camouflage netting loops are designed on the back of the hood and body. The camouflage netting is made of high-performance infrared-resistant stealth material, laser-cut to create a three-dimensional camouflage surface, and connected to the hood and back loops via buckles. This enhances stealth capabilities in the large infrared heat source area on the back, making it more suitable for combat and improving camouflage effectiveness. Other features include a vertically opening quick-access pocket on the chest; a large, slanted, waterproof pocket at the hem; ergonomic arm pockets on the upper arms; and adjustable Velcro loops at the cuffs and hems.

[0081] like Figure 2 The image shows a thermal infrared camouflage outfit designed in Example 2. The camouflage outfit includes a top and trousers. Figure 2 In the image, the left image shows the front of the garment, the middle image shows the back of the garment, and the right image shows the visual effect of the 3D camouflage mesh wear-resistant block being fixedly connected to the back of the garment.

[0082] Figure 3 The camouflage effect diagram of the thermal infrared camouflage clothing designed for Example 2; Figure 3 In the middle, the left side shows ordinary clothing, and the right side shows the thermal infrared camouflage clothing of Example 2.

[0083] Example 3

[0084] In Example 3, the design of the thermal infrared camouflage cloak includes:

[0085] Referring to the design method of Embodiment 1, Embodiment 3 designs a thermal infrared camouflage cloak. The cloak body is made of dozens of irregularly shaped, unequal-sized, and differently emissive thermal infrared functional fabrics, irregularly spliced ​​together according to a thermal simulation model. The splicing seams are designed as discontinuous, asymmetrical curves and folds. The cloak can effectively conceal the natural contours of the human body, such as the armpits and sides of the legs. The cloak is a hooded design, and a porous, low-emissivity fabric mask is used for the face and breathing area, which does not affect vision and breathing, and effectively reduces the high heat radiation of the face. The mask and hood are connected by snap fasteners and are detachable.

[0086] The fabric employs three emissivity levels: low (ε=0.3), medium (ε=0.6), and high (ε=0.8). Low-emissivity fabric is used for high-heat areas such as the head and chest, high-emissivity fabric for low-heat areas such as the arms and legs, and medium-emissivity fabric for the remaining areas. The low-ε areas create "cold spots," the high-ε areas reflect ambient temperature or simulate heat points, and the medium-ε areas act as a transition, resulting in varying local thermal contrast between any point on the target surface and the background, alternating between positive and negative values, thus "dissolving" into the background at the pixel level.

[0087] The thermal infrared camouflage clothing and design method disclosed in the embodiments of the present invention have at least the following beneficial technical effects:

[0088] (1) Based on the distribution pattern of human body temperature, three functional fabrics with high, medium and low infrared emissivity are used as the main fabric of the camouflage clothing. The aim is to divide the high infrared thermal radiation of the human body, reduce the visibility of the human body outline in the thermal infrared imager, and enable the human body to better integrate into the temperature characteristics of different regions after wearing the camouflage clothing to achieve excellent thermal infrared camouflage and stealth capabilities.

[0089] (2) The 3D camouflage net integrated module design is adopted to achieve a high degree of integration between the human body and the environment under visible light visual reconnaissance, so that the camouflage clothing has excellent visible light camouflage and stealth functions.

[0090] (3) It can better meet the temperature characteristics of different regions, realize multiple uses of one garment, and has strong applicability and economy.

[0091] (4) The camouflage uniform is designed based on the individual combat uniform pattern. It adopts camouflage pattern stitching technology, integrates 3D camouflage net and integrated module design, so that the camouflage uniform has excellent visible light-thermal infrared compatible camouflage function. The design of quick-access bags, adjustment loops, etc. improves the efficiency of carrying other equipment, wearing comfort and movement flexibility of the camouflage uniform, adapts to the needs of high-intensity tactical marches, and does not require individual soldiers to add extra changing procedures in actual application. It can better meet the actual combat needs of individual soldiers for day and night visible light and thermal infrared camouflage and stealth.
