Description

Technical Field

[0001] This utility model relates to the field of stab-proof clothing fabric technology, and specifically discloses a lightweight stab-proof clothing breathable structure. Background Technology

[0002] Stab-resistant vests in the field of personal protective equipment are crucial for law enforcement, security, and defense personnel to protect themselves from stab and cut injuries caused by sharp objects. Traditional soft stab-resistant vests typically use high-performance fibers such as ultra-high molecular weight polyethylene and aramid to form the main protective layer through a multi-layered, densely laminated structure. The high strength and high modulus of these fibers absorb and disperse the kinetic energy of the puncture. This type of solution is technologically mature, offers reliable protection, and has become the mainstream in the market.

[0003] However, due to limitations in material properties and structural design, these types of stab-proof vests generally suffer from poor breathability and heat dissipation. The tightly packed structure of numerous fibers significantly hinders air circulation and the expulsion of perspiration, resulting in a hot and humid microenvironment inside the garment. Furthermore, to maintain the required protection level, a large amount of material is often used, leading to a heavy overall weight and poor flexibility. These problems severely impact the wearer's comfort and freedom of movement, especially during prolonged or high-intensity duty, easily leading to increased physical exertion and heat stress, thus reducing the practicality of the equipment. Utility Model Content

[0004] This invention proposes a lightweight stab-proof vest with a breathable structure. By constructing multi-level breathable channels, it effectively promotes air circulation and heat and moisture removal inside and outside the vest, solving the problem of stuffiness and dampness in traditional products. The structure is stable, reliable, and durable, and is suitable for various duty scenarios that require wearing stab-proof vests for extended periods of time, significantly improving users' willingness to wear it and their duty efficiency.

[0005] This utility model is implemented as follows: a lightweight stab-proof and breathable structure includes an outer protective layer, a middle buffer layer and an inner comfort layer arranged sequentially from the outside to the inside. The middle buffer layer is composed of multiple independent buffer units arranged in an array, and a first breathable channel for air circulation is formed between adjacent buffer units.

[0006] The inner comfort layer has multiple three-dimensional protrusions on the side that is close to the human skin, and the three-dimensional protrusions form a second breathable channel for air circulation between the human skin and the human skin.

[0007] The outer protective layer has multiple micro-ventilation holes, the positions of which correspond to the first ventilation channel and are interconnected.

[0008] As a preferred embodiment of the lightweight stab-proof garment breathable structure of this utility model, the cushioning unit includes a flexible bladder, the interior of which is filled with stab-proof material, and the cross-sectional shape of the flexible bladder is one of a circle, a regular hexagon, and a square.

[0009] As a preferred embodiment of the lightweight stab-proof and breathable structure of this utility model, the flexible bladder is made of thermoplastic polyurethane elastomer.

[0010] As a preferred embodiment of the lightweight stab-proof garment breathable structure of this utility model, the stab-proof material is one or more composite materials selected from ultra-high molecular weight polyethylene fiber felt, aramid nonwoven fabric, or metal wire mesh.

[0011] As a preferred embodiment of the lightweight stab-proof and breathable structure of this utility model, the three-dimensional raised structure is one of the following: a grid-like rib, an array of hemispherical protrusions, and a wavy ridge integrally formed on the inner wall of the inner comfort layer.

[0012] As a preferred embodiment of the lightweight stab-proof garment breathable structure of this utility model, the inner comfort layer is made of moisture-wicking and quick-drying fabric, which is polyester quick-drying fabric.

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0023] Please see Figure 1-4 A lightweight stab-proof garment with a breathable structure includes an outer protective layer 1, a middle buffer layer 2, and an inner comfort layer 3 arranged sequentially from the outside to the inside. The middle buffer layer 2 is composed of multiple independent buffer units 4 arranged in an array, and a first breathable channel 5 for air circulation is formed between adjacent buffer units 4.

[0024] The inner comfort layer 3 has multiple three-dimensional raised structures 6 on the side close to human skin, and the three-dimensional raised structures 6 and human skin form a second breathable channel 10 for air circulation.

[0025] The outer protective layer 1 has multiple micro air vents 7, the positions of which correspond to the first air vent 5 and are interconnected.

[0026] In this embodiment, a three-layer breathable structure is used to achieve heat dissipation. Specifically, the micro-ventilation holes 7 on the outer protective layer 1 are precisely aligned and connected with the first breathable channel 5 naturally formed by the array of multiple independent buffer units 4 in the middle buffer layer 2, forming the main path for external air to enter. The three-dimensional protrusion structure 6 on the inner side of the inner comfort layer 3 supports the fabric in contact with human skin, forming a second breathable channel 10 that allows for micro-air circulation. This allows external cold air to enter the first breathable channel 5 through the micro-ventilation holes 7 and flow laterally. Through convection and heat transfer, the hot and humid air accumulated in the second breathable channel 10 is displaced and discharged. Thus, without weakening the core protective capability provided by the puncture-resistant materials 9 such as ultra-high molecular weight polyethylene fiber felt filled in the flexible bladder 8, a highly efficient and active air circulation structure is constructed, significantly improving the overall coolness and comfort of the wearer.

[0027] As a technical optimization of this utility model, the buffer unit 4 includes a flexible capsule 8, the interior of which is filled with puncture-resistant material 9, and the cross-sectional shape of the flexible capsule 8 is one of a circle, a regular hexagon, and a square.

[0028] In this embodiment: the buffer unit 4 adopts a flexible capsule 8 structure with internal puncture-resistant material 9, which discretizes the traditional large-area continuous solid protective layer into multiple independent units. Each unit can deform independently and absorb energy when subjected to puncture impact, avoiding excessive stress diffusion. At the same time, the gap between the units naturally forms the first ventilation channel 5, which takes into account both protection and ventilation.

[0029] As a technical optimization of this utility model, the flexible capsule 8 is made of thermoplastic polyurethane elastomer.

[0030] In this embodiment: the high strength, high toughness and good hot melt weldability of thermoplastic polyurethane elastomer can reliably encapsulate the internal stab-proof material 9, preventing it from shifting or agglomerating, ensuring uniform and stable protective performance, while the soft capsule material does not affect the overall flexibility of the garment.

[0031] As a technical optimization of this utility model, the stab-resistant material 9 is one or more composite materials selected from ultra-high molecular weight polyethylene fiber felt, aramid nonwoven fabric or metal wire mesh.

[0032] In this embodiment, the extremely high strength of these materials is used to resist and dissipate the piercing kinetic energy of the sharp blade, providing the entire structure with the proven and reliable protective force required to meet the protection standards, which is the basic guarantee of the protective performance.

[0033] As a technical optimization of this utility model, the three-dimensional protruding structure 6 is one of the following: a grid-like rib, an array of hemispherical protrusions, and a wave-shaped protrusion, which are integrally formed on the inner wall of the inner comfort layer 3.

[0034] In this embodiment, the contact surface between the fabric and the skin is permanently opened by physical structures such as mesh ribs or protrusions, ensuring that the second ventilation channel 10 can continue to exist regardless of whether the garment is compressed, thus guaranteeing the stability and reliability of the moisture-wicking and heat-dissipating effect.

[0035] As a technical optimization of this utility model, the inner comfort layer 3 is made of moisture-wicking and quick-drying fabric, which is polyester quick-drying fabric.

[0036] In this embodiment: the moisture-wicking and quick-drying fabric is a polyester quick-drying fabric, which accelerates the absorption of sweat and its rapid evaporation on its large surface area, further enhancing the dryness of the skin. Together with the second breathable channel 10, it improves comfort.

[0037] As a technical optimization of this utility model, the outer protective layer 1 is made of Oxford cloth, and the outer protective layer 1, the middle buffer layer 2 and the inner comfort layer 3 are fixedly connected by peripheral stitching.

[0038] In this embodiment, a highly abrasion-resistant fabric is selected to protect the internal structure, and a sturdy stitching method is used to ensure that the three-layer structure does not shift, thus guaranteeing the product's durability, overall structural integrity, and the longevity of each layer's function.

[0039] The working principle and usage process of this utility model: The micro-ventilation holes 7 on the outer protective layer 1 serve as air exchange inlets, communicating with the first ventilation channel 5 located directly below and between the buffer units 4 in the middle buffer layer 2; when the wearer moves, there is a temperature and pressure difference between the air inside and outside the garment, and the cooler external air is drawn into the first ventilation channel 5 through the micro-ventilation holes 7 and flows laterally in these crisscrossing mesh channels; the flowing air exchanges heat with the walls of the buffer unit 4, carrying away some heat; at the same time, the sweat and heat generated by the human skin are initially absorbed and diffused by the quick-drying fabric used in the inner comfort layer 3, and are further absorbed by the three-dimensional raised structure 6. The space maintained by the second ventilation channel 10 is accommodated; finally, the heated air flowing in the first ventilation channel 5 pushes the hot and humid air in the second ventilation channel 10 upward and outward through convection, so that it is discharged through other micro ventilation holes 7, completing a continuous breathing cycle; when threatened by puncture, the impact force is transmitted from the outer protective layer 1 to the specific buffer unit 4 that is hit. The puncture-resistant material 9 in the unit absorbs and disperses the puncture kinetic energy through the stretching, shearing and friction of the fibers. Since the units are independent of each other, the impact force is effectively constrained locally, avoiding rigid deformation of the overall plate and minimizing the blunt force injury transmitted to the human body.

[0041] However, the above description is only a specific embodiment of this utility model and should not be construed as limiting the scope of implementation of this utility model. Therefore, any substitution of equivalent components or equivalent changes and modifications made in accordance with the scope of protection of this utility model should still fall within the scope of the claims of this utility model.
