Description

Technical Field

[0001] This utility model relates to the technical field, specifically to a flyknit shoe upper that mimics the protective support of the human skeleton. Background Technology

[0002] Flyknit uppers are widely popular due to their lightweight, breathability, and good fit. However, traditional flyknit materials are mainly composed of flexible yarns, which have relatively weak structural support and impact resistance. During exercise, key areas of the foot, such as the metatarsals and ankle joints, are easily subjected to external impacts or require additional support to ensure stability.

[0003] In existing technologies, the following methods are commonly used to enhance the support of flyknit uppers: one is to heat-press or glue independent TPU support pieces to the outside of the flyknit layer. This method increases the manufacturing process, and the joint between the support piece and the flyknit layer is easy to peel off, affecting the overall integrity and aesthetics; the other is to increase the number of flyknit layers or use thicker yarns, but this method will significantly increase the weight and stiffness of the fabric, sacrificing the lightweight and breathable advantages of flyknit uppers. Utility Model Content

[0004] The purpose of this invention is to solve the problems of insufficient support, weak protective performance, and poor overall integrity with existing flyknit shoe uppers.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A biomimetic skeletal protective support flyknit upper includes a main body of the upper, integrally woven from flyknit fibers. The main body comprises a base flyknit layer and a biomimetic protective support structure region disposed on the base flyknit layer. The biomimetic protective support structure region includes a reinforcing layer woven from TPU fibers. The reinforcing layer has a mesh topology composed of multiple connected polygonal grid units. The reinforcing layer is integrally woven with the base flyknit layer. The reinforcing layer uses TPU fibers as weft yarns or filler yarns, interwoven with the yarns of the base flyknit layer.

[0006] A further improvement is that the polygonal grid unit is at least one of hexagons, pentagons, or triangles.

[0007] A further improvement is that the connecting nodes of the polygonal mesh unit are provided with a thickened structure.

[0008] A further improvement is that the width and / or thickness of the connecting ribs of the polygonal mesh unit is greater than the fiber density of the internal region of the polygonal mesh unit.

[0009] A further improvement is that the connection nodes of the polygonal grid units form a thickened structure by increasing the number or density of TPU fiber padding during weaving.

[0010] A further improvement is that the width and / or thickness of the connecting ribs of the polygonal mesh unit is greater than the fiber density of the internal region of the polygonal mesh unit by increasing the amount of TPU fiber used.

[0011] A further improvement is that the biomimetic protective support structure area corresponds to at least one of the metatarsal area, ankle area, and arch area of ​​the human foot.

[0012] A further improvement is that the TPU fibers in the reinforcing layer are transparent or semi-transparent fibers.

[0013] A further improvement is that the mesh density and / or fiber thickness of the mesh topology vary in a gradient within the biomimetic protective support structure region.

[0014] A further improvement is that the base flyknit layer is made of polyester, nylon, or a blend of polyester and nylon; it mainly provides basic wrapping, breathability, and comfort for the shoe upper.

[0015] Compared with existing technologies, the above technical solution has the following advantages: The layout of the biomimetic protective support structure simulates the distribution of human foot bones (such as metatarsals and ankle bones), and provides targeted reinforcement in key areas that require support and protection. The reinforcement layer adopts a polygonal mesh topology similar to wire mesh. This structure has been proven in materials science and structural mechanics to achieve maximum structural stability with minimal materials. At the same time, by thickening the nodes and strengthening the connecting ribs, the stress transmission path of the trabeculae in the bones is further simulated. By leveraging the programmability of the flyknit process, the soft base material (basic flyknit layer) and the supportive TPU reinforcement layer are completed simultaneously in a single weaving process, achieving a seamless connection. This avoids the delamination risks associated with traditional bonding processes, ensuring the integrity and aesthetics of the fabric. The TPU fibers themselves have a certain degree of transparency, and when woven into a mesh structure and combined with other flyknit yarns, they can create a unique visual appearance that showcases both technological aesthetics and the design flexibility of the shoe upper. Excellent directional support and protection: The biomimetic protective support structure is arranged according to the biomechanical needs of the foot, providing precise support and impact protection for specific areas.

[0016] Good balance: While providing enhanced support, the mesh structure ensures that the fabric maintains good flexibility and breathability in non-reinforced areas, achieving a balance between support and flexibility.

[0017] Lightweight and durable: The one-piece molding process avoids additional adhesives and bonding processes, reducing the overall weight and eliminating the risk of delamination at the seams, thus improving the product's durability.

[0018] High degree of design freedom: By adjusting the size, shape, density of the mesh, as well as the thickness and color of the TPU fibers, a wide variety of appearances and performance characteristics can be created to meet different design needs. Attached Figure Description

[0021] Explanation of the attached labels: 1. Main body of the shoe upper; 2. Basic flyknit layer; 3. Bionic protective support structure area; 4. Reinforcing layer. Detailed Implementation

[0022] See Figure 1 As shown, the technical solution adopted in this specific embodiment is: a human skeletal protective support flyknit upper, comprising an upper body 1 integrally woven from flyknit fibers, characterized in that: the upper body 1 includes a base flyknit layer 2 and a biomimetic protective support structure region 3 disposed on the base flyknit layer 2; the biomimetic protective support structure region 3 includes a reinforcing layer 4 woven from TPU fibers; the reinforcing layer 4 is a mesh topology structure composed of multiple polygonal grid units connected together; the reinforcing layer 4 is integrally woven with the base flyknit layer 2 through flyknitting. The reinforcing layer 4 uses TPU fibers as weft yarns or filler yarns interwoven with the yarns of the base flyknit layer 2.

[0023] The polygonal mesh unit is at least one of hexagons, pentagons, or triangles. The mesh topology is preferably a hexagonal honeycomb mesh, as hexagons have been proven to be one of the most efficient structures in nature (such as honeycombs) and in engineering, effectively dispersing stress.

[0024] The connection nodes of the polygonal mesh unit are provided with a thickened structure.

[0025] Wherein, the width and / or thickness of the connecting ribs of the polygonal mesh unit is greater than the fiber density of the internal region of the polygonal mesh unit.

[0026] The connection nodes of the polygonal grid units are thickened by increasing the number or density of TPU fiber padding during weaving.

[0027] The width and / or thickness of the connecting ribs of the polygonal mesh unit are greater than the fiber density of the internal region of the polygonal mesh unit by increasing the amount of TPU fiber used.

[0028] The biomimetic protective support structure region 3 corresponds to at least one of the metatarsal region, ankle region, and arch region of the human foot.

[0029] The TPU fibers in the reinforcing layer 4 are transparent or semi-transparent fibers.

[0030] The mesh density and / or fiber thickness of the mesh topology of the reinforcing layer 4 vary in a gradient within the biomimetic protective support structure region 3.

[0031] The basic flyknit layer 2 is made of polyester, nylon, or a blend of polyester and nylon; it mainly provides basic wrapping, breathability and comfort for the shoe upper.

[0032] The working principle of this invention is as follows: The base flyknit layer uses conventional shoe flyknit yarns, such as polyester, nylon, or their blends, mainly providing basic wrapping, breathability, and comfort functions for the shoe upper; the biomimetic protective support structure is woven in specific functional areas of the shoe upper (e.g., the metatarsal area corresponding to the five metatarsal bones of the foot, the ankle area covering the ankle, and the arch area requiring support) through flyknit computer programming. In these areas, TPU fibers are introduced as weft yarns or filler yarns, interwoven with the yarns of the base flyknit layer to form the reinforcing layer; the mesh topology is preferably a hexagonal honeycomb mesh, because hexagons have been proven to be one of the most efficient structures in nature (such as honeycombs) and in engineering, effectively dispersing stress. The size of the mesh can be adjusted according to the required support strength. For example, a smaller mesh is used in areas with higher expected impact (such as the toe and outer ankle), and a slightly larger mesh is used in areas where flexibility is required; During the weaving process, by increasing the number or density of TPU fiber padding, a thickened structure is formed at the connection nodes of the grid. At the same time, the width and / or thickness of the connecting ribs that make up the grid border can also be greater than the fiber density in the inner area of ​​the grid by increasing the amount of TPU fiber. This design simulates the characteristic of dense bone distribution along the stress path in the skeleton, so that stress can be effectively transmitted and dispersed through the reinforced nodes and ribs, further optimizing mechanical properties. TPU fibers are preferably made of transparent or semi-transparent materials, which makes them look more technological and can create a layering effect with the base layer color, increasing the aesthetic appeal of the design.
