Description

Technical Field

[0001] This utility model relates to the field of shoe upper technology, specifically to a translucent jacquard reinforced shoe upper. Background Technology

[0002] Shoes are a type of clothing accessory whose function is to protect and cover the user's feet. They are basically composed of a sole and an upper. The sole is the lower part that contacts the ground, while the upper is the upper part that is located on top of the sole. The upper covers the user's foot and connects with the sole to fix the sole to the user's foot, preventing the sole from falling off. The design of the upper can effectively improve the integration of the shoe and foot, and make the shoe more protective of the foot and provide better warmth.

[0003] While the aforementioned existing technologies can solve the corresponding technical problems, they still have certain drawbacks: In order to obtain higher tensile strength, existing shoe uppers often use high-density weaving methods combined with high-strength yarns to form the upper. Although this can improve the tensile strength of the upper and make it suitable for high-intensity sports, it will lead to increased hardness and decreased porosity of the upper. This can easily cause the feet to feel tight and stuffy when worn. Furthermore, when the upper is in contact with the foot for a long time, it can easily rub against the foot, causing injury. An additional inner lining layer is needed, which further increases the weight of the upper and reduces breathability, making it difficult to balance the strength of the upper and the comfort of wearing. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing a permeable jacquard reinforced shoe upper with high tensile strength and high comfort.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a permeable jacquard reinforced shoe upper, comprising a shoe upper body formed by low-density weaving of elastic yarn and an opening formed integrally by cutting the shoe upper body at the heel position of the human foot. The shoe upper body also has several three-dimensional protrusions formed by jacquard process on both sides and at the forefoot position of the human foot. The shoe upper body also has several diagonally distributed tensile permeable layers formed by jacquard process at the edge of the shoe upper body.

[0006] A further improvement is that the sides and forefoot of the shoe upper are also formed with diagonally thickened lines using a jacquard process.

[0007] A further improvement is that the upper body is also equipped with a reinforcing layer for the insertion opening, which is fixed by heat pressing at the edge of the insertion opening.

[0008] A further improvement is that the tensile permeable layer is composed of several tensile frame edges bonded together, and the tensile frame is a hexagonal yarn structure formed on the shoe upper body by jacquard process.

[0009] After adopting the above technical solution, the beneficial effects of this utility model are as follows: During the wearing process, the upper body of this utility model is formed by low-density weaving of elastic yarn, thus having a high degree of fit and softness to the foot, as well as high breathability. There is an anti-tensile permeable layer at the edge of the upper body. The anti-tensile permeable layer is formed by connecting multiple hexagonal yarn structures, which can improve the strength of the forefoot and edge of the upper body, thus making the upper body less prone to excessive deformation and cracking at the forefoot and edge. Moreover, the anti-tensile permeable layer composed of hexagonal yarn has a certain deformation capacity and can quickly recover after deformation, thereby ensuring the softness and comfort of the upper body and preventing a stiff touch. Combined with three-dimensional raised dots, the strength of the side and forefoot of the upper is greatly improved, and the anti-stepping ability of the forefoot is enhanced. Thus, it has high anti-deformation ability and protection while also having high comfort. Attached Figure Description

Detailed Implementation

[0012] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0013] See Figure 1-2As shown, the technical solution adopted in this specific embodiment is: a permeable jacquard reinforced shoe upper, including a shoe upper body 1 formed by low-density weaving of elastic yarn and an opening 2 formed by cutting and integrally forming the shoe upper body 1 at the heel position of the human foot. Several three-dimensional protrusions 6 are formed by jacquard process on both sides of the shoe upper body 1 and at the forefoot position of the human foot. Several diagonally distributed tensile permeable layers 3 are formed by jacquard process at the edge of the shoe upper body 1. The tensile permeable layers 3 are composed of several tensile frame edges bonded together. The tensile frame is a hexagonal yarn structure formed by jacquard process on the shoe upper body 1. During the forming process, the fabric of the shoe upper body 1 is first formed by low-density weaving method combined with high-elasticity yarn. Low-density weaving refers to a weaving method with ≤10 stitches per inch. Then, the shape of the shoe upper body 1 is formed by cutting. Specifically, spandex core-spun yarn with an elastic elongation rate ≥150% is used as the weaving yarn. Using a computerized warp knitting machine or computerized jacquard flat knitting machine equipped with multiple combs and electronic jacquard devices as the knitting equipment, the knitting structure of different areas is controlled by a preset program. In the large area corresponding to the main body of the shoe upper, the program-controlled equipment performs low-density knitting with a mesh structure or warp flat structure with ≤10 stitches per inch to form a soft, breathable and elastic shoe upper body 1 base. The entry point 2 is formed at the heel of the shoe upper body 1 by cutting. Subsequently, at the edge of the shoe upper body 1 and the forefoot, a tensile permeable layer 3 is formed by jacquard process. The tensile permeable layer 3 is obliquely distributed and is composed of multiple hexagonal yarn structures. The side length of the hexagonal yarn structure of the tensile permeable layer 3 is 1-3mm. The edges of adjacent hexagons are close together and have a certain deformation capacity. After deformation, it can quickly recover. Specifically, in the key stress areas of the shoe upper edge and the forefoot, the program-controlled equipment uses relatively thicker elastic yarns to knit a continuous hexagonal grid structure by warp knitting weft weaving. The hexagons have a side length of 1-3mm, and adjacent hexagons share yarns and are connected to each other. During weaving, this hexagonal mesh structure interweaves and integrates with the surrounding low-density matrix, forming a reinforced layer that combines tensile strength and breathability. Finally, multiple three-dimensional raised dots 6 are formed on the sides and forefoot of the upper body 1 using a high-density jacquard process. The height of the raised dots 6 is 0.5-2mm, and the diameter is 1-3mm. These raised dots give the forefoot and sides of the upper body 1 high tensile strength and resistance to trampling, preventing collapse. Specifically, on the sides and forefoot of the upper, the equipment automatically switches to a local padding or flattened structure, introducing additional padding yarns or increasing yarn tension to accumulate yarns in this area, forming a solid structure higher than the matrix surface. By controlling the weaving cycle, this structure forms an array of raised dots with a height of 0.5-2mm and a diameter of 1-3mm.These raised dots are woven seamlessly into the base material in one piece. The formed upper is then sewn into the midsole of the shoe. The laces are inserted through the front of the insertion port 2, and the foot is then inserted through the port 2. Tightening the laces completes the shoe-wearing process. The aforementioned jacquard process uses a computerized jacquard machine to control yarn tension and change the weave structure during the weaving process, forming three-dimensional raised dots 6 and a tensile-resistant permeable layer 3 on the upper body 1. During wear, the upper body 1 is woven with elastic yarn at a low density, resulting in a high degree of fit and softness to the foot, as well as high breathability. Tensile-resistant material is present at the edges of the upper body 1. The permeable layer 3, a tensile-resistant permeable layer 3, is formed by connecting multiple hexagonal yarn structures. This improves the strength of the forefoot and edge areas of the upper body 1, making the upper body 1 less prone to excessive deformation and cracking in these areas. The tensile-resistant permeable layer 3, composed of hexagonal yarns, also has a certain degree of deformability, allowing it to quickly recover after deformation. This ensures the softness and comfort of the upper body 1 and prevents a harsh feel. Combined with the three-dimensional raised dots 6, this significantly increases the strength of the sides and forefoot of the upper, and enhances the anti-stepping ability of the forefoot area. Thus, it offers high resistance to deformation and protection while also providing high comfort. On both sides and the forefoot of the upper body 1, diagonal thickened yarn layers 5 are formed using a jacquard process. These diagonal thickened yarn layers 5 form an angle of 30-60° with the horizontal direction. The elastic yarn is spandex core-spun yarn with an elastic elongation ≥150%. The jacquard process for forming the diagonal thickened yarn layers 5 is the same as the jacquard process described above. Specifically, on specific paths on the sides and forefoot of the upper, the program-controlled equipment uses double-stranded spandex core-spun yarn and switches to a tucked or chain-knitted structure, weaving along a trajectory at an angle of 30-60° with the horizontal direction, thereby forming diagonal reinforcing ribs with higher strength on the base material. These reinforcing ribs are also directly woven into the base material during the weaving process, which helps to further improve the strength of the upper body 1 at the gap of the tensile permeable layer 3 through the diagonal thickened yarn layers 5, thus further improving the deformation resistance and protective performance of the upper body 1. The upper body 1 is also reinforced with a TPU film strip at the edge of the insertion opening 2 by heat pressing. This improves the tear resistance of the upper body 1 at the edge of the insertion opening 2. The shoe lace body 1 is also less likely to crack at the insertion opening 2 when the shoelaces are tightened or when worn for a long time, thus improving its service life.

[0014] To verify the technical effect of the translucent jacquard reinforced shoe upper provided by this utility model, a third-party authoritative testing laboratory was commissioned to conduct a comparative test on the sample of the embodiment of this utility model (hereinafter referred to as "the shoe upper of this utility model") and a commercially available sports shoe upper using traditional high-density weaving technology (hereinafter referred to as "the comparative shoe upper") in accordance with relevant national standards.

[0015] 1. Sample Preparation This utility model sample is prepared according to the process described in the specific embodiments of this specification. The upper base is made of low-density (10 needles / inch) spandex core-spun yarn and is integrally molded with three-dimensional raised dots, hexagonal tensile-resistant permeable layer and diagonal thickened yarn layer.

[0016] Comparative sample: The upper of the shoe is made of mainstream high-strength sports shoes, using high-density (22 needles / inch) plain weave polyester fiber, without any special local reinforcement structure.

[0017] 2. Test Items and Results

[0018]

[0019] 3. Experimental Conclusions The above experimental data fully demonstrates that the permeable jacquard reinforced shoe upper provided by this utility model successfully combines "high strength" and "high comfort". Specifically: In terms of key mechanical properties (tear resistance and puncture resistance), it reaches or even surpasses traditional high-density uppers, meeting the needs of sports protection.

[0020] It has an overwhelming advantage in indicators that directly affect comfort, such as breathability, resilience, and pressure distribution, fundamentally solving the pain points of traditional high-performance shoe uppers that are "hard, stuffy, and cause blisters".

[0021] The comprehensive performance data supports the beneficial effects described in this utility model and confirms the practicality and progressiveness of this technical solution.

[0022] The working principle of this utility model is as follows: During molding, the upper body 1 is first formed using a low-density weaving method combined with high-elasticity yarn. Then, the upper body 1 is cut to form its shape, and an opening 2 is created at the heel position of the upper body 1. Subsequently, a tensile-resistant permeable layer 3 is formed at the edges and forefoot of the upper body 1 using a jacquard process. The tensile-resistant permeable layer 3 is obliquely distributed and composed of multiple hexagonal yarn structures. The edges of these hexagonal yarn structures are interlocked, providing a certain degree of flexibility. The shoe has good shape retention and can quickly recover after deformation. Finally, multiple three-dimensional raised dots 6 are formed on the sides and forefoot of the upper body 1 using a high-density jacquard process. These raised dots 6 give the forefoot and sides of the upper body 1 high tensile strength and anti-stepping performance, preventing collapse. The formed upper is then sewn into the midsole. The shoelaces are threaded through the front of the insertion opening 2, and the foot is then inserted through the opening 2. Tightening the shoelaces completes the wearing process. During wear, the upper body 1 is formed by low-density weaving of elastic yarn. This results in a high degree of fit and softness for the foot, along with high breathability. A tensile-resistant permeable layer 3 is located at the edge of the upper body 1. This layer 3 is formed by multiple hexagonal yarn structures, which increases the strength of the forefoot and edge areas of the upper body 1. This makes the upper body 1 less prone to excessive deformation and cracking in these areas. Furthermore, the hexagonal yarn tensile-resistant permeable layer 3 has a certain degree of deformability, allowing it to quickly recover after deformation, effectively dispersing and bearing tensile stress during exercise, preventing… Excessive deformation or cracking of the upper, and the inherent elasticity of the mesh structure, ensures the softness and comfort of the upper body 1 without compromising comfort, preventing a harsh touch. Combined with three-dimensional raised dots 6, the strength of the sides and forefoot of the upper is greatly improved, and the anti-stepping ability of the forefoot area is enhanced. This design of "low-density soft matrix" and "high-density functional structure integrated weaving" fundamentally solves the contradiction between strength and comfort in traditional uppers, thus achieving high resistance to deformation and protection while also providing high comfort.
