Description

Technical Field

[0001] This utility model relates to the field of footwear technology, specifically to an abrasion-resistant outdoor footwear 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] Although the existing technologies mentioned above can solve the corresponding technical problems, they still have certain drawbacks: when the existing shoe uppers are used for outdoor sports, such as mountaineering, the environment is often harsh, and the feet are easily exposed to splashing water droplets and gravel. Sometimes, due to terrain factors, the feet may also directly rub against the ground, which can easily cause the shoe uppers to wear out. Damaged shoe uppers will significantly reduce their fit and waterproof performance, making it difficult for existing shoe uppers to withstand long-term use when used for outdoor sports. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing an outdoor shoe upper that is wear-resistant, has a long service life, and is durable.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an abrasion-resistant outdoor shoe upper, comprising an upper body woven from abrasion-resistant yarn and an entrance integrally formed on the upper body at the heel of the human foot, wherein an abrasion-resistant reinforcing structure is fixed at the edge of the upper body by a flat embroidery process, and a zipper reinforcing structure extending from the side to the forefoot of the upper body is sewn and fixed on the side of the upper body.

[0006] A further improvement is that the wear-resistant reinforcement structure includes a mesh reinforcement layer fixed to the edge of the shoe upper body by a flat embroidery process, and a suede piece fixed to the upper surface of the mesh reinforcement layer by a flat embroidery process.

[0007] A further improvement is that the wear-resistant reinforcement structure also includes a reinforcing film that is fixed to the edge of the suede piece at the forefoot position of the upper body by a seamless hot-stamping process.

[0008] A further improvement is that the cable reinforcement structure includes a first cable sewn and fixed to the edge of the abrasion-resistant reinforcement structure on the upper body. The first cable extends from the heel of the upper body to the forefoot of the upper body. The first cable is woven into shape using high-density yarn and a high-density weaving method.

[0009] A further improvement is that the cable reinforcement structure also includes a second cable sewn to the side of the upper body and extending to the forefoot position of the upper body. The second cable is woven into shape using a high-density weave method with high-density yarn.

[0010] A further improvement is that a water-repellent layer woven from waterproof yarn is fixed between the cable reinforcement structure and the insertion point using a flat embroidery process.

[0011] A further improvement is that several ventilation holes are formed by punching holes on the forefoot area of ​​the shoe upper.

[0012] A further improvement is that the upper body is also provided with a suede reinforcing layer at the edge of the insertion opening.

[0013] A further improvement is that a penetration reinforcement sheet is fixed to the penetration reinforcement layer using a seamless hot-film process.

[0014] After adopting the above technical solution, the beneficial effects of this utility model are as follows: When worn, the forefoot area of ​​the upper body of this utility model has a wear-resistant reinforced structure, which covers the area of ​​the upper body that is prone to contact with external gravel and ground. Therefore, when the upper body is impacted by gravel and rubs against the ground during outdoor sports, the damage to the upper body can be greatly reduced, and the wear resistance of the upper body can be greatly improved. This ensures the integrity of the upper body and the wrapping performance of the foot, improves the wrapping protection and service life of the upper body, and is suitable for long-term use in outdoor sports.

[0017] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0018] See Figs. 1-2As shown, the technical solution adopted in this specific embodiment is: an abrasion-resistant outdoor shoe upper, comprising an upper body 1 woven from abrasion-resistant yarn and an opening 2 integrally formed on the upper body 1 at the heel of the human foot. The abrasion-resistant yarn is 500D high-strength nylon yarn, twill woven, with a weaving density of 50 yarns per inch. An abrasion-resistant reinforcement structure is fixed to the edge of the upper body 1 using a flat embroidery process. The abrasion-resistant reinforcement structure includes a mesh reinforcement layer 5 fixed to the edge of the upper body 1 using a flat embroidery process and a suede piece 3 fixed to the upper surface of the mesh reinforcement layer 5 using a flat embroidery process. A cable reinforcement structure extending from the side to the forefoot of the upper body 1 is sewn and fixed to the side of the upper body 1. The cable reinforcement structure includes... A first drawstring 7 is sewn and fixed to the edge of the abrasion-resistant reinforcement structure of the upper body 1. The first drawstring 7 extends from the heel of the upper body 1 to the forefoot. The first drawstring 7 is woven into shape using high-density yarn and a high-density weaving method. During the shaping process, the fabric used for the upper body 1 is first woven with abrasion-resistant yarn. After the fabric is shaped, the upper body 1 is cut and shaped. Then, the insertion opening 2 is formed by cutting. Subsequently, a mesh reinforcement layer 5 is fixed to the outer edge of the upper body 1 using a flat embroidery process. The flat embroidery process uses 2 strands of polyester embroidery thread with a stitch length of 2mm, and embroiders one layer. The mesh reinforcement layer 5 is a mesh-like layer structure formed by high-strength yarn. Specifically, the mesh reinforcement layer 5 is made of 300D high-strength polyester. The upper is woven with nylon yarn, with a mesh size of 3mm×3mm. Suede pieces 3 are fixed to the edges of the mesh reinforcement layer 5 using a flat embroidery process. Suede pieces 3 have high abrasion resistance and are not easily damaged by friction, thus significantly improving the strength of the edges of the upper body 1—the areas most likely to contact the ground and be scratched by gravel—preventing rapid breakage during contact with the ground and gravel. Simultaneously, a first cable 7 is sewn and fixed to the upper body 1. The first cable 7 is woven with high-density yarn using a high-density weaving method. Specifically, the high-density weaving method uses 600D high-strength nylon yarn with a weaving density of 100 yarns per inch, providing high tensile and deformation resistance. After being sewn and fixed to the upper body 1, it improves the strength of the edges of the upper body 1. The upper and forefoot provide excellent support and resistance to deformation, effectively locking the foot inside the upper body 1 during outdoor activities. Even with slight damage to the upper body 1, it effectively secures the foot. The upper is then sewn into the midsole, and the laces are threaded through the front of the insertion opening 2. The foot is then inserted into the shoe through the insertion opening 2 and the laces are tightened. When worn, the forefoot area of ​​the upper body 1 features a durable, reinforced structure made of a mesh reinforcement layer 5 and suede sheets 3, covering areas of the upper body 1 that are prone to contact with gravel and the ground. Therefore, during outdoor activities, when the upper is impacted by gravel or rubs against the ground, the suede sheets 3 absorb most of the friction and impact damage.Furthermore, the mesh reinforcement layer 5 holds the upper body 1 in place, preventing excessive deformation due to friction and impact. This significantly reduces damage to the upper body 1, greatly improving its abrasion resistance. Consequently, it ensures the integrity of the upper body 1 and its support for the foot, enhancing the upper's protective fit and lifespan, making it suitable for extended use in outdoor sports. The wear-resistant reinforcement structure also includes a reinforcement film 4 fixed to the edge of the suede piece 3 at the forefoot position of the upper body 1 by a seamless hot-stamping process. The reinforcement film 4 is a thermoplastic polyurethane film with a thickness of 0.2mm. The hot-stamping process parameters are: temperature 140℃, pressure 0.4MPa, and time 20s. This is beneficial to further improve the strength of the forefoot edge of the upper body 1 through the reinforcement film 4. When moving forward, the strength of the forefoot position of the foot, which is most susceptible to gravel impact and ground friction, is further improved. At the same time, the reinforcement film 4 supports the forefoot position of the upper body 1, so that it will not deform excessively and squeeze the foot when subjected to gravel impact, thus making it safer to wear. The cable reinforcement structure also includes a second cable 8 sewn and fixed to the side of the upper body 1 and extending to the forefoot position of the upper body 1. The second cable 8 is formed in the same way as the first cable 7. The second cable 8 is woven with high-density yarn using a high-density weaving method, which is conducive to forming a support strip structure that wraps around the side of the foot and the forefoot position by working together with the first cable 7, further improving the support and wrapping of the foot on the side and forefoot position of the upper body 1. Between the cable reinforcement structure and the through-hole 2, a water-repellent layer 10 woven from waterproof yarn is fixed by a flat embroidery process. The waterproof yarn is 400D nylon yarn treated with fluorocarbon hydrophobic agent, with a surface water contact angle of 115°, which helps to improve the waterproof performance of the shoe upper body 1, and thus makes it more suitable for outdoor sports. The forefoot area of ​​the upper body 1 also has several ventilation holes 9 formed by punching. The ventilation holes 9 have a diameter of 2mm and a spacing of 10mm, and are distributed in a rectangular array, which helps to improve the breathability of the upper body 1 and make it more comfortable to wear. The upper body 1 is also provided with a suede reinforcing layer 6 at the edge of the insertion opening 2, which helps to improve the strength of the upper body 1 at the insertion opening 2 and makes it less prone to cracking; The insertion reinforcement layer 6 is also fixed with an insertion reinforcement piece 11 by a seamless hot-stamping process. The insertion reinforcement piece 11 is a thermoplastic polyurethane film with a thickness of 0.15mm. The hot-stamping process parameters are the same as those of the reinforcement film 4, which helps to further improve the strength of the upper body 1 at the insertion 2 position. At the same time, after tightening the shoelaces, the upper body 1 is less likely to be damaged due to the tension of the shoelaces.

[0019] To verify the comprehensive performance of the abrasion-resistant outdoor shoe upper of this utility model, a series of tests were conducted on the shoe upper sample prepared according to the preferred embodiment of this utility model (made with the specific parameters described above, such as 500D high-strength nylon upper body, 300D polyester mesh layer, and 0.2mm TPU reinforcing film), and compared with the upper of a mainstream outdoor hiking shoe on the market (comparison sample). The test results are as follows: 1. Abrasion resistance test Test standard: Refer to GB / T 21196.2-2007 "Textiles - Martindale Method for Determination of Abrasion Resistance of Fabrics".

[0020] Test conditions: pressure 12 kPa, abrasive is standard wool felt.

[0021] Test results: The sample of this utility model, after 25,000 rubs, showed no yarn breakage, holes or significant thinning in the key wear area of ​​the forefoot (the composite area of ​​the suede and the reinforcing film), only a slight increase in surface fuzzing.

[0022] Comparative samples: After 8,000 rubs, localized yarn wear and thinning appeared on the edge of the shoe upper; after 15,000 rubs, tiny holes appeared.

[0023] Conclusion: The abrasion resistance of the shoe upper of this invention is more than three times that of the comparative sample, and the abrasion resistance is significantly improved.

[0024] 2. Tear resistance test Test standard: Refer to GB / T 3917.3-2009 "Textiles - Tear properties of fabrics - Part 3: Determination of tear strength of trapezoidal specimens".

[0025] Test area: The area where the side of the shoe upper is stitched with reinforced cable structure.

[0026] Test results: The sample of this utility model has an average tear strength of 256 N. The failure mode is mainly the gradual breakage of the yarn, and the cable structure effectively prevents the tear from extending.

[0027] Comparative sample: Average tear strength was 158 N. The crack propagated rapidly upon failure.

[0028] Conclusion: Due to the presence of the cable-reinforced structure, the tear resistance of this invention is increased by approximately 62%.

[0029] 3. Water-repellent performance test Test standard: Refer to AATCC 22-2017 "Water resistance: Spray test".

[0030] Test results: This utility model sample: After spraying, the surface only had a small number of fine water droplets and was not wetted, achieving a rating of 90 points (level 4). This is mainly due to the water-repellent layer woven from waterproof yarn.

[0031] Comparison sample: Some wet patches appeared on the surface, with a rating of 70 points (level 3).

[0032] Conclusion: This invention has superior immediate water-repellent capability.

[0033] 4. Moisture permeability and air permeability test Test standard: Refer to GB / T 12704.2-2009 "Textiles - Test methods for moisture permeability of fabrics - Part 2: Evaporation method".

[0034] Test results: The sample of this utility model has a moisture permeability of 4,200 g / (m²·24h). The vents and fabric structure work together to ensure the expulsion of moisture.

[0035] Comparative sample (non-directional pore design): moisture permeability is 3,100 g / (m²·24h).

[0036] Conclusion: This invention enhances protection while increasing moisture permeability by approximately 35%, effectively improving wearing comfort.

[0037] 5. Comprehensive fatigue simulation test Test method: Place the finished shoe in a footwear bending tester to simulate walking, with the forefoot bending angle at 60° and the frequency at 1Hz, and test continuously for 100,000 times.

[0038] Post-test check: The sample of this utility model has the following characteristics: the upper structure is intact, without delamination or cracking; the drawstrings are not loose, and the stitching is firm; there is no glue separation at the junction of the reinforcing film and the suede sheet.

[0039] Comparison sample: There are obvious creases and localized frayed areas at the bends of the shoe upper, and some seams show signs of wear.

[0040] Conclusion: After simulating long-term use, the upper of this invention maintains structural integrity better and has superior durability.

[0041] The above experimental data fully demonstrate that this utility model, through the synergistic design of the "wear-resistant reinforced structure" and the "cable reinforced structure," and supplemented by specific material and process parameters, achieves a comprehensive and significant improvement in wear resistance, tear resistance, protection, and comfort, thus fulfilling the purpose of the utility model.

[0042] The working principle of this utility model is as follows: During the molding process, the upper body 1 is first woven with abrasion-resistant yarn. After the fabric is shaped, the upper body 1 is cut and formed. Then, the insertion opening 2 is formed. Subsequently, a mesh reinforcement layer 5 is fixed to the outer edge of the upper body 1 using a flat embroidery process. The mesh reinforcement layer 5 is a mesh-like layer structure formed by high-strength yarn. Suede pieces 3 are fixed to the edges of the mesh reinforcement layer 5 using a flat embroidery process. Suede pieces 3 have high abrasion resistance and are not easily damaged by friction, thus significantly improving the strength of the edges of the upper body 1, i.e., the areas that easily come into contact with the ground and are scratched by gravel, preventing rapid breakage when in contact with the ground and gravel. Simultaneously, a first pull cord 7 is sewn and fixed to the upper body 1. The first pull cord 7 is woven with high-density yarn using a high-density weaving method, possessing high tensile and deformation resistance. After being sewn and fixed to the upper body 1, it improves the support and deformation resistance of the sides and forefoot of the upper body 1, allowing for better performance during outdoor activities. The shoe fully locks the foot inside the upper body 1, effectively securing it even after slight damage. The upper is then sewn into the midsole, and the laces are threaded through the front of the insertion point 2. The foot is then inserted through the insertion point 2 and the laces are tightened. When worn, the forefoot area of ​​the upper body 1 features a durable, reinforced structure made of a mesh reinforcement layer 5 and suede sheets 3, covering areas prone to contact with gravel and the ground. During outdoor activities, the suede sheets 3 absorb most of the friction and impact damage when the upper is impacted by gravel or rubbed against the ground. The mesh reinforcement layer 5 holds the upper body 1 in place, preventing excessive deformation due to friction and impact, significantly reducing damage and greatly improving its abrasion resistance. This ensures the integrity of the upper body 1 and its support for the foot, enhancing its protection and lifespan, making it suitable for extended use in outdoor activities.
