Description

Technical Field

[0001] This utility model relates to the field of footwear manufacturing technology, specifically to a biomimetic fish gill flyknit upper. Background Technology

[0002] Flyknit uppers are widely used due to their advantages of being lightweight, breathable, and moldable in one piece. However, the breathability of existing flyknit uppers largely relies on static diffusion through the material's pores. When users are exercising or when foot heat increases dramatically, their breathability is insufficient to quickly expel hot and humid air, resulting in a stuffy and humid environment inside the shoe, affecting wearing comfort, and potentially even causing health problems. Utility Model Content

[0003] The purpose of this invention is to solve the problem that the breathability of existing flyknit shoe uppers relies mainly on the static diffusion of the material's pores. When the user is exercising and the heat generated by the foot increases dramatically, the breathability is insufficient to quickly expel hot and humid air, resulting in a stuffy and humid environment inside the shoe and affecting wearing comfort.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A biomimetic fish gill flyknit upper, characterized by: comprising The upper body is made of one-piece knitted flyknit, and the upper body consists of an outer layer, a middle support layer, and an inner layer from top to bottom. At least one biomimetic fish gill-like air-permeable area that runs through the surface layer, the middle support layer, and the inner layer; The intermediate support layer forms a three-dimensional hollow channel in the biomimetic fish gill ventilation area; The outer and inner layers are provided with dynamic ventilation holes in the areas corresponding to the three-dimensional hollow channels, and the dynamic ventilation holes are woven from highly elastic transparent yarn.

[0005] A further improvement is that the cross-sectional shape of the three-dimensional hollow channel is a circular, elliptical, or gill-like multi-segment curve.

[0006] A further improvement is that the high-elastic transparent yarn is woven into an elastic coil or corrugated structure, and the dynamic ventilation holes are in a slightly closed state when the main body of the shoe upper is static, and open when dynamically bent or when the internal air pressure increases.

[0007] A further improvement is that the high-elastic transparent yarn is a transparent polyurethane (TPU) yarn or silicone fiber.

[0008] A further improvement is that the intermediate support layer is made of hydrophobic monofilament yarn woven by jacquard or weft insertion; the hydrophobic monofilament yarn is polyester monofilament.

[0009] A further improvement is that the surface layer is made of polyester or nylon woven together; this ensures wear resistance and aesthetics.

[0010] A further improvement is that the inner layer is woven from a moisture-wicking and quick-drying functional yarn; the moisture-wicking and quick-drying functional yarn is Coolmax® fiber; it is close to the skin to enhance comfort.

[0011] A further improvement is that the layout of the biomimetic fish gill breathable area on the main body of the shoe upper corresponds to the sweaty areas of the human foot.

[0012] A further improvement is that the biomimetic gill ventilation area is arranged in an array or gradient density distribution.

[0013] Compared with existing technologies, the above technical solution has the following advantages: Biomimetic structure: mimicking the stacked multi-layered structure of fish gills, the three-layer composite design and three-dimensional hollow channels increase the surface area for gas exchange and provide airflow channels; Functional biomimicry: mimicking the opening and closing of fish gills with the water flow during respiration, the elasticity of highly elastic transparent yarn allows the dynamic ventilation holes to automatically open and close when the foot moves (simulating the respiratory muscle movement of fish). During movement, the air pressure inside the shoe increases and the fabric deforms, causing the ventilation holes to open and release air; when stationary, the ventilation holes elastically retract, effectively blocking the intrusion of external dust or a small amount of moisture. Combining craftsmanship and materials: Utilizing the designability of the flyknit process, functional structures are directly woven into shape, and transparent materials are applied to the ventilation area, enhancing the aesthetic value of the product while ensuring functionality; Active dynamic breathability: It changes the traditional breathability mode of fabrics that relies on static diffusion, and realizes active breathing function that increases with the intensity of exercise; Highly efficient heat dissipation and dehumidification: The synergistic effect of three-dimensional channels and air vents can quickly expel hot and humid air from inside the shoe, significantly improving wearing comfort; Lightweight and stable structure: The one-piece flyknit construction ensures the integrity and lightweight nature of the fabric, while the middle support layer provides breathability and also ensures the support and shape stability of the upper.

[0017] See Figures 1-2 As shown, the technical solution adopted in this specific embodiment is: a biomimetic fish gill flyknit upper, comprising: The shoe upper body 1 is made of one-piece knitted fly knit, and the shoe upper body 1 consists of an outer layer 11, a middle support layer 12, and an inner layer 13 from top to bottom; At least one biomimetic fish gill ventilation area 2 that penetrates the surface layer 12, the intermediate support layer 12 and the inner layer 13; The intermediate support layer 12 forms a three-dimensional hollow channel 3 within the biomimetic fish gill ventilation area 2; The outer layer 11 and the inner layer 13 are provided with dynamic ventilation holes 4 in the area corresponding to the three-dimensional hollow channel 3. The dynamic ventilation holes 4 are woven from high-elastic transparent yarn.

[0018] The cross-sectional shape of the three-dimensional hollow channel 3 is a circular, elliptical, or gill-like multi-segment curve.

[0019] The highly elastic transparent yarn is woven into elastic coils or a corrugated structure. The dynamic ventilation holes are slightly closed when the main body of the shoe upper 1 is static, and open when dynamically bent or when the internal air pressure increases. Specifically, these yarns are designed as elastic coils or corrugated structures in the weaving structure. In a natural state (static), the coils tighten, keeping the ventilation holes slightly closed. When the shoe upper bends due to walking or running, or when the internal temperature and air pressure increase, the elastic coils are stretched, thereby opening the dynamic ventilation holes and forcing airflow exchange. This process simulates the opening and closing of fish gill valves in rhythm with breathing.

[0020] The high-elastic transparent yarn is a transparent polyurethane (TPU) yarn or silicone fiber.

[0021] The intermediate support layer 12 is made of hydrophobic monofilament yarn woven by jacquard or weft insertion; the hydrophobic monofilament yarn is polyester monofilament.

[0022] The outer layer 11 is made of polyester or nylon and is responsible for wear resistance and appearance.

[0023] The inner layer 13 is woven from a moisture-wicking and quick-drying functional yarn; the moisture-wicking and quick-drying functional yarn is Coolmax® fiber; it is close to the skin to enhance comfort.

[0024] The layout of the biomimetic fish gill breathable area 2 on the main body of the shoe upper 1 corresponds to the sweaty area of ​​the human foot.

[0025] The biomimetic fish gill ventilation region 2 is arranged in an array or gradient density distribution.

[0026] The working principle of this invention is as follows: The shoe upper is woven in one step on a flyknitting machine through computer programming; the outer layer mainly uses conventional shoe flyknitting yarns (such as polyester and nylon) to be responsible for wear resistance and appearance; the inner layer preferentially selects moisture-wicking and quick-drying functional yarns (such as Coolmax®) to be close to the skin to improve comfort; the middle support layer uses monofilament yarns (such as polyester monofilament) with slightly higher stiffness and hydrophobic properties, woven by jacquard or weft insertion to form three-dimensional hollow channels in a preset area; the cross-section of these channels can be circular, elliptical, or irregularly shaped more like fish gills. In the surface and inner regions corresponding to the three-dimensional hollow channels, highly elastic transparent yarns (such as transparent TPU yarns) are introduced for weaving. These yarns are designed as elastic coils or corrugated structures in the weaving structure. In the natural state (static), the coils are tightened, keeping the ventilation holes in a slightly closed state. When the shoe upper bends due to walking or running, or when the temperature and air pressure inside the shoe increase, the elastic coils are stretched, thereby opening the dynamic ventilation holes and forcing airflow exchange. This process simulates the opening and closing of fish gill valves with the respiratory rhythm. The layout of the biomimetic fish gill ventilation area is scientifically designed based on the heat and moisture distribution map of the human foot. It can be mainly placed on areas prone to sweating, such as the back of the foot, the corresponding parts of the toe joints, and the outer arch of the foot. These areas can be arranged in an array, or a gradient density distribution can be adopted according to the amount of sweating (that is, the more prone the area to sweating, the denser the distribution of ventilation units).

[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions provided are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection of this utility model as defined by the appended claims and their equivalents.
