Description

Technical Field

[0001] This utility model relates to the field of functional textile materials technology, specifically a single-layer jacquard lightweight and wear-resistant shoe upper. Background Technology

[0002] Currently, the manufacturing of athletic shoe uppers commonly employs multi-layer composite processes, using hot melt adhesives to bond multiple functional materials to achieve breathability, support, and fit. However, this approach has significant drawbacks: multi-layer structures are prone to interfacial separation due to insufficient interlayer bonding, leading to a high risk of delamination after long-term use; traditional mesh fabrics often increase weight to improve tear resistance, making it difficult to balance breathability and lightweight; homogeneous weaving density designs cannot adapt to the biomechanical characteristics of the foot, creating a conflict between forefoot flexibility and heel lockdown requirements; production processes are inefficient, with conventional dyeing processes consuming large amounts of water and causing severe wastewater pollution, hindering sustainable development; and color performance is limited by traditional jacquard techniques, making it difficult to meet the demands of the high-end market for color accuracy and customization. Therefore, we propose a single-layer jacquard lightweight and durable upper. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a single-layer jacquard lightweight and wear-resistant shoe upper that combines functional integration, environmentally friendly production and wearability, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a single-layer jacquard lightweight and wear-resistant shoe upper, comprising a single-layer jacquard fabric. The single-layer jacquard fabric is designed with a three-dimensional topological structure and integrally formed by knitting warp knitting process, integrating an adhesive layer, a tear-resistant layer and a breathable layer. The surface of the single-layer jacquard fabric is provided with a palm extension area and a heel locking area. The single-layer triple composite structure is achieved through three-dimensional jacquard weaving, which can effectively prevent delamination.

[0005] Furthermore, the single-layer jacquard fabric is dyed using a supercritical CO2 dyeing process, and its color fastness to washing is ≥4.

[0006] Furthermore, the breathable layer has a biomimetic honeycomb mesh structure with an adjustable mesh size of 0.8-2.5mm and a warp breathability of 3800g / m² / 24h. The tear-resistant layer is embedded with 20D high-strength polyester jacquard yarn with a weaving density of 30-50 threads / cm². The bonding layer uses hot melt yarn with a melting point of 120℃, distributed in a mesh pattern. The biomimetic honeycomb mesh and microgroove dual-module breathable design achieves a moisture permeability of 4000g / m² / 24h, which is effectively improved compared to traditional fabrics.

[0007] Furthermore, the single-layer jacquard fabric has a knitting density of 12-25 stitches / inch gradient distribution. The metatarsal portion of the forefoot extension area of ​​the single-layer jacquard fabric is denser to 18 stitches / inch, with a tensile modulus of 12MPa. The gradient density knitting technology enables the lateral elongation rate of the forefoot area to reach 35%±5%, and the longitudinal elongation rate of the heel locking area to be ≤8%, which effectively improves the foot fit compared to traditional mesh fabrics.

[0008] Furthermore, the lateral elongation rate of the forefoot extension area of ​​the single-layer jacquard fabric is 35%±5%, and the longitudinal elongation rate of the heel locking area of ​​the single-layer jacquard fabric is ≤8%.

[0009] Furthermore, the bonding layer contains a bio-based spandex component at a content of 30%, and the surface of the breathable layer is hydrophobically treated with a water contact angle >130°.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: This single-layer jacquard lightweight and wear-resistant shoe upper has the following advantages:

[0011] 1. A single-layer triple composite structure is achieved through three-dimensional jacquard weaving, eliminating the risk of interlayer delamination in traditional 3-5 layer composite fabrics and effectively preventing delamination.

[0012] 2. Gradient density weaving technology enables the lateral extension rate of the forefoot area to reach 35%±5%, and the longitudinal extension rate of the heel locking area to be ≤8%, which effectively improves the foot fit compared with traditional mesh fabric.

[0013] 3. The biomimetic honeycomb mesh and microgroove dual-module breathable design achieves a moisture permeability of 4000g / m² / 24h, which is effectively improved compared with traditional fabrics;

[0014] 4. Compared with traditional multi-layer fabrics, single-layer fabrics have a significantly reduced unit weight and are more wear-resistant. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 This embodiment provides a technical solution: 1. A single-layer jacquard lightweight and wear-resistant shoe upper, comprising a single-layer jacquard fabric, the single-layer jacquard fabric being integrally formed by a three-dimensional topological structure design and a knitted warp knitting process, integrating an adhesive layer 1, a tear-resistant layer 2, and a breathable layer 3, the surface of the single-layer jacquard fabric being provided with a palm extension area 5 and a heel locking area 6, the single-layer triple composite structure being achieved through three-dimensional jacquard weaving, which can effectively prevent delamination;

[0023] Single-layer jacquard fabrics are dyed using supercritical CO2 dyeing process, with a color fastness to washing of ≥4 grade;

[0024] The breathable layer 3 has a biomimetic honeycomb mesh structure with an adjustable mesh size of 0.8-2.5mm and a warp breathability of 3800g / m² / 24h. The tear-resistant layer 2 is embedded with 20D high-strength polyester jacquard yarn with a weaving density of 30-50 threads / cm². The bonding layer 1 uses hot melt wire 41 with a melting point of 120℃, which is distributed in a mesh pattern. The biomimetic honeycomb mesh and microgroove dual-module breathable design achieve a moisture permeability of 4000g / m² / 24h, which is effectively improved compared with traditional fabrics.

[0025] The single-layer jacquard fabric has a knitting density of 12-25 stitches / inch gradient distribution. The metatarsal part of the forefoot extension zone 5 of the single-layer jacquard fabric is denser to 18 stitches / inch, with a tensile modulus of 12MPa. The gradient density knitting technology makes the lateral extension rate of the forefoot area reach 35%±5%, and the longitudinal extension rate of the heel locking area ≤8%, which effectively improves the foot fit compared with traditional mesh fabric.

[0026] The lateral elongation rate of the forefoot extension zone 5 of the single-layer jacquard fabric is 35%±5%, and the longitudinal elongation rate of the heel locking zone 6 of the single-layer jacquard fabric is ≤8%.

[0027] The bonding layer 1 contains a bio-based spandex component of 30%, and the surface of the breathable layer 3 is hydrophobically treated with a water contact angle >130°.

[0028] The working principle of this invention, a single-layer jacquard lightweight and wear-resistant shoe upper, is as follows: Through 0.01mm displacement control using RJ series electronic yarn guide needles, three functional structures are simultaneously formed during single-layer weaving. The upper layer, with 0.8-2.5mm honeycomb holes, provides ventilation channels; the middle layer, with 30-50 threads / cm² of 20D high-strength polyester yarn, forms a tear-resistant network; and the lower layer, with hot-melt wires, melts during shoe last heat setting to form a three-dimensional foot-fitting structure. The dual-module airflow channels, through the synergistic effect of active ventilation in the forefoot area and passive moisture wicking in the arch area, maintain the humidity inside the shoe at 50-55%RH (at 25℃). It is worth noting that the 120℃ hot-melt wire bonding technology used in this invention indirectly achieves antibacterial function while realizing three-dimensional molding—experiments show that hot-pressing treatment can reduce the survival rate of Staphylococcus aureus to 7.2%.

[0029] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
