Description

Technical Field

[0001] The invention relates to the technical field of special clothing, in particular to a pair of stab-proof, bullet-proof and warm-keeping clothing and trousers for military and police use. Background Art

[0002] As social security needs continue to increase, the risks faced by military and police personnel when performing their tasks are also increasing. Traditional protective equipment often only focuses on protective performance, while ignoring comfort and practicality. Under extreme climatic conditions, military and police personnel need equipment that can provide effective protection while maintaining physical comfort. Although existing stab-proof bulletproof vests have certain protective capabilities, they are insufficient in terms of warmth and comfort. In addition, these equipment are often bulky, limiting the wearer's flexibility and mobility.

[0003] Therefore, developing a military and police dual-purpose stab-proof and bullet-proof thermal underwear with high protective performance, good warmth retention and comfort is of great significance for improving the work efficiency and safety of military and police personnel. Summary of the invention

[0004] The technical problem to be solved by the present invention is to reduce the thickness of clothing and improve the wearing flexibility while ensuring the stab-proof, bullet-proof and warm-keeping effects of clothing. To solve the above technical problems, the technical solution provided by the present invention is as follows:

[0005] A military and police dual-purpose stab-proof, bullet-proof and warm-keeping clothing and trousers, comprising a coat and trousers, wherein the coat and trousers are provided with stab-proof, bullet-proof and warm-keeping materials;

[0006] The stab-proof, bullet-proof and warm-keeping material comprises an aromatic polyamide fiber laminate layer, an organic aerogel and a carbon fiber mesh layer;

[0007] The aromatic polyamide fiber pressing layer is formed by pressing multiple layers of aromatic polyamide fibers, and the carbon fiber mesh layer is formed by staggeredly stacking multiple layers of carbon fiber meshes;

[0008] The organic aerogel and the carbon fiber mesh layer are arranged in the middle of the stab-proof, bullet-proof and thermal insulation material, and the aromatic polyamide fiber pressing layer sandwiches the organic aerogel and the carbon fiber mesh layer from the top and bottom respectively and presses them into shape; after pressing and shaping, the organic aerogel fills all the gaps in the stab-proof, bullet-proof and thermal insulation material.

[0009] As an improvement, the number of layers of aromatic polyamide fibers in the aromatic polyamide fiber pressing layer is 6-32.

[0010] As an improvement, the number of layers of mesh carbon fibers in the carbon fiber mesh layer is 2-5 layers.

[0011] As an improvement, the mesh aperture of the mesh carbon fiber is 0.2-1.2 cm, and the mesh aperture of the carbon fiber mesh layer after multiple layers of mesh carbon fiber are staggered and stacked is no more than 0.4 cm.

[0012] As an improvement, the gaps include gaps produced when aromatic polyamide fibers and mesh carbon fibers are woven, interlayer gaps when multiple layers of aromatic polyamide fibers are pressed together, interlayer gaps when multiple layers of mesh carbon fibers are superimposed, and interlayer gaps between pressed layers of aromatic polyamide fibers and mesh layers of carbon fibers.

[0013] As an improvement, the pore volume of the organic aerogel is greater than 99% and the thermal conductivity is lower than 0.016w (mK).

[0014] As an improvement, the stab-proof, bullet-proof and thermal insulation material further includes a second structure, which does not include aerogel and is formed only by laminating an aromatic polyamide fiber laminate layer and a carbon fiber mesh layer.

[0015] As an improvement, the main material of the top and pants is the stab-proof, bullet-proof and warm-keeping material;

[0016] The top is provided with a stand-up collar at the neckline and cuffs at the cuffs;

[0017] The coat and pants are provided with stab-proof, bullet-proof and warm-keeping materials of a second structure at the corresponding crotch, armpits, elbows and knees;

[0018] The stab-proof, bullet-proof and thermal insulation material and the stab-proof, bullet-proof and thermal insulation material of the second structure are filled into a mold at corresponding positions and then pressurized and formed at one time.

[0019] As an improvement, the jacket and the trousers are connected and tightened by a buckled belt.

[0020] As an improvement, the top is designed with a long upper body, a short back, wide shoulders, and a tight waist, and the top is in a V shape that is wide at the top and narrow at the bottom.

[0021] As an improvement, the trousers are provided with cover cloths at the corresponding crotch and coccyx positions, and the top of the cover cloth is sewn and fixed to the trouser body; the cover cloth is made of stab-proof, bullet-proof and warm-keeping material.

[0022] The present invention has the advantages that:

[0023] 1. The present invention uses an aromatic polyamide fiber laminated layer in combination with an organic aerogel and a carbon fiber mesh layer to produce a stab-proof, bullet-proof and warm-keeping material. Aromatic polyamide fibers have good mechanical properties, heat resistance and insulation properties. Organic aerogel has the characteristics of light weight, low density, high specific surface area and high porosity, and has a strong heat insulation and warmth-keeping effect. In addition, organic aerogel has good impact resistance, and compounding in the material can effectively improve the material's stab-proof and bullet-proof effects. The present invention adds multiple layers of superimposed grid carbon fibers to the material. The carbon fibers have the characteristics of light weight and high strength, and can effectively prevent gun or dagger penetration. In addition, the grid structure of the carbon fibers can play a role of skeleton support when compounding the aerogel, and can form a mesh tension in the aerogel, further improving the aerogel's stab-proof and bullet-proof capabilities.

[0024] 2. The present invention adopts a one-time pressurized molding process when making the stab-proof, bullet-proof and warm-keeping material. During the pressurization process, the aerogel can fill the gaps in the aromatic polyamide fiber laminate layer and the carbon fiber mesh layer, effectively improving the bonding effect of the layers in the stab-proof, bullet-proof and warm-keeping material, improving the integrity of the material, and improving the stab-proof and warm-keeping effects of the material. In addition, pressurized molding can effectively reduce the thickness of the material, avoid the clothing being too bulky, and affect the flexibility when wearing.

[0025] 3. The present invention arranges a second structure of stab-proof, bullet-proof and warm-keeping material at the corresponding joint positions with a higher degree of mobility, and reduces the thickness of the material by not providing or reducing the addition of aerogel, thereby improving the flexibility of the clothing at the corresponding joints.

[0026] 4. The present invention provides targeted protection at the neck, chest, back, abdomen, shoulder blades and other critical or vulnerable areas, which can effectively protect the life of the wearer. The present invention optimizes the shape of the top, using a V-shaped design that is wide at the top and narrow at the bottom, which can effectively cover up the bloated appearance caused by the filler and often give the wearer an upright and strong posture.

It is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0039] In addition, the terms "horizontal", "vertical", "overhanging" and the like do not mean that the components must be absolutely horizontal or overhanging, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0040] In the description of the embodiments of the present invention, "plurality" means at least 2.

[0041] In the description of the embodiments of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0042] Example 1

[0043] The present embodiment discloses a pair of stab-proof, bullet-proof and warm-keeping clothes and trousers for military and police use, comprising a coat 1 and trousers 2, on which stab-proof, bullet-proof and warm-keeping materials 3 are provided.

[0044] The stab-proof, bullet-proof and thermal insulation material 3 comprises an aromatic polyamide fiber laminate layer 31 , an organic aerogel 32 and a carbon fiber mesh layer 33 .

[0045] The aromatic polyamide fiber laminated layer 31 is formed by laminating multiple layers of aromatic polyamide fibers, and the carbon fiber mesh layer 33 is formed by staggered stacking of multiple layers of mesh carbon fibers 331;

[0046] The organic aerogel 32 and the carbon fiber mesh layer 33 are arranged in the middle of the stab-proof, bullet-proof and thermal insulation material 3, and the aromatic polyamide fiber pressing layer 31 sandwiches the organic aerogel 32 and the carbon fiber mesh layer 33 from the top and bottom respectively and presses them into shape; after pressing and shaping, the organic aerogel 32 fills all the gaps in the stab-proof, bullet-proof and thermal insulation material.

[0047] The voids include voids generated when aromatic polyamide fibers and mesh carbon fibers are woven, voids between layers when multiple layers of aromatic polyamide fibers are pressed together, voids between layers when multiple layers of mesh carbon fibers are superimposed, and voids between pressed layers of aromatic polyamide fibers and mesh layers of carbon fibers. The pore volume of the organic aerogel is greater than 99%, and the thermal conductivity is less than 0.016w (mK). Filling the voids with organic aerogel 32 can effectively improve the bonding effect of the layers in the stab-proof, bullet-proof and thermal insulation material, improve the integrity of the material, and improve the stab-proof and thermal insulation effects of the material.

[0048] The number of layers of aromatic polyamide fibers in the aromatic polyamide fiber laminated layer 31 is 6-32.

[0049] The number of layers of mesh carbon fiber in the carbon fiber mesh layer 33 is 3. The mesh aperture of the mesh carbon fiber is 0.2-1.2 cm. After the 3 layers of mesh carbon fiber mesh are staggered and superimposed, the carbon fiber mesh layer 33 has a smaller aperture, and its mesh aperture is not greater than 0.4 cm. Therefore, it can effectively prevent the puncture of gun bayonets and daggers. At the same time, because the organic aerogel 32 is filled into the gaps in the carbon fiber mesh layer 33, the relative displacement of the layers of the carbon fiber mesh layer 33 can be effectively avoided, thereby avoiding the movement of local mesh carbon fibers during puncture and avoiding excessive expansion of the aperture, thereby improving the puncture-proof and bullet-proof effects.

[0050] The stab-proof, bullet-proof and thermal insulation material further comprises a second structure 4 , which is not provided with aerogel but is only formed by laminating an aromatic polyamide fiber laminate layer 31 and a carbon fiber mesh layer 33 .

[0051] like Figure 1-3 As shown, the main material of the jacket 1 and the pants 2 is stab-proof, bullet-proof and warm-keeping material 3.

[0052] The coat 1 is provided with a stand-up collar 11 at the neckline and a cuff 12 at the cuff. The stand-up collar 11 is made of stab-proof, bullet-proof and warm-keeping material 3. The coat 1 is designed with a long upper body, a short back, wide shoulders, and a tight waist. The overall shape is wide at the top and narrow at the bottom. It can effectively cover up the bloated appearance caused by the filler and often gives the wearer an upright and strong posture.

[0053] The coat 1 and the trousers 2 are provided with stab-proof, bullet-proof and warm-keeping materials of the second structure 4 at the corresponding positions of the crotch 21 , the armpits 13 , the elbows 14 and the knees 22 .

[0054] The stab-proof, bullet-proof and thermal insulation material 3 and the stab-proof, bullet-proof and thermal insulation material of the second structure 4 are filled into the clothing mold at corresponding positions and then pressurized and formed at one time.

[0055] The jacket 1 and the trousers 2 are connected and tightened by a buckled belt 5 .

[0056] In this embodiment, the aromatic polyamide fiber laminated layers 31 at the top and bottom of the stab-proof and bullet-proof thermal insulation material 3 are both pressed with 16 layers of aromatic polyamide fibers. The thickness of the 16 layers of aromatic polyamide fibers after compaction is about 0.5 cm, and the thickness of the organic aerogel 32 is 4 cm. After the carbon fiber mesh layer 33 is pressed and formed into one piece, the overall thickness of the thermal insulation material is about 2 cm, which can effectively avoid the appearance being too bloated.

[0057] The trousers are provided with stab-proof, bullet-proof and warm-keeping materials of the second structure 4 at the positions corresponding to the crotch 21, the armpit 13, the elbow 14 and the knee 22. The stab-proof, bullet-proof and warm-keeping materials of the second structure 4 are not provided with aerogel, but are only formed by laminating 6 layers of aromatic polyamide fibers and a carbon fiber mesh layer 33, which can further reduce the thickness and ensure the flexibility of the joint positions.

[0058] Example 2

[0059] In this embodiment, the trousers 2 are provided with a cover cloth 6 at the corresponding crotch 21 and coccyx position. The cover cloth 6 is made of stab-proof, bullet-proof and warm-keeping material 3, and the top is sewed and fixed to the main body of the trousers 21.

[0060] The cover cloth 6 can further protect the crotch 21 and coccyx of the wearer.

[0061] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
