Description

Technical Field

[0001] The utility model relates to the technical field of footwear, in particular to a protective and breathable upper and a shoe. Background Art

[0002] With the rise of sports and leisure fashion, flying woven uppers are favored by consumers for their unique weaving process and lightness. Flying woven uppers are usually woven with highly elastic fiber materials. Their unique mesh structure makes the uppers have good air permeability, which can relieve the stuffiness caused by long-term wear of the feet to a certain extent and keep the environment inside the shoes dry and comfortable. However, although flying woven uppers have certain air permeability, their air permeability is still limited in practical applications. Due to the characteristics of fiber materials and the limitations of weaving technology, the size and distribution of the air holes in flying woven uppers are often not uniform, resulting in unstable air permeability of the uppers, which is difficult to meet the high requirements for air permeability in specific sports or environments. In addition, the durability of flying woven uppers is also an issue that cannot be ignored. Due to the characteristics of the weaving structure, flying woven uppers are more susceptible to wear and tear than traditional leather or synthetic material uppers. Especially in frequent sports or complex environments, the uppers are easily damaged, which not only affects the service life of the shoes, but also may threaten the safety of the wearer's feet. More importantly, the performance of flying woven uppers in terms of protection is not satisfactory. Due to its mesh structure, the Flyknit upper is not able to resist the intrusion of sharp objects, debris or liquids. During exercise, if the wearer accidentally encounters such situations, it may cause foot injuries or infections, seriously affecting the sports experience and health. Utility Model Content

[0003] The purpose of the utility model is to overcome the above-mentioned defects or problems existing in the background technology, and to provide a protective and breathable upper and shoe. The shoe adopts a protective and breathable upper material to achieve the effects of simple structure, good breathability and protective function, providing the wearer with a safe, comfortable and healthy wearing experience.

[0004] To achieve the above objectives, each embodiment of the present invention adopts the following technical solutions but is not limited to the following solutions:

[0005] The first technical solution relates to a protective and breathable upper, including an upper body, wherein the upper body is woven by a plurality of TPU yarns in an interwoven manner to form at least one TPU yarn arrangement layer, wherein the TPU yarns are fixedly connected by hot-melt pressing at overlapping positions, and breathable winding gaps are formed between the TPU yarns after weaving; a protective layer is compounded on the side of the upper body close to the foot, wherein the protective layer is woven with a material having puncture-resistant and cut-resistant properties, and wherein the protective layer is provided with a breathable grid structure.

[0006] The second technical solution is based on the first technical solution, wherein the protective layer is a carbon fiber mesh layer woven from carbon fibers.

[0007] The third technical solution is based on the first technical solution, wherein the TPU yarn includes a first TPU wire and a second TPU wire, the first TPU wire is spirally wound on the second TPU wire, and the melting point of the first TPU wire is lower than the melting point of the second TPU wire.

[0008] The fourth technical solution is based on the third technical solution, wherein the melting point of the first TPU line is 90°C-100°C, and the melting point of the second TPU line is 160°C-180°C.

[0009] The fifth technical solution is based on the first technical solution, and further includes a soft layer and an antibacterial layer connected to the protective layer in sequence, the antibacterial layer contacts the instep, and the soft layer is located between the protective layer and the antibacterial layer.

[0010] The sixth technical solution is based on the fifth technical solution, wherein the antibacterial layer is a mesh layer woven from bamboo charcoal fibers.

[0011] The seventh technical solution is based on the sixth technical solution, wherein the surface of the bamboo charcoal fiber is covered with cotton material.

[0012] The eighth technical solution is based on the fifth technical solution, wherein the soft layer is made of a foam material with a breathable mesh.

[0013] The ninth technical solution is based on any one of the first to eighth technical solutions, wherein a shoe comprises a sole and an upper installed on the sole, and the upper adopts the above-mentioned protective and breathable upper.

[0014] From the above description of the various embodiments of the present invention, it can be seen that, compared with the prior art, the various embodiments of the present invention have the following beneficial effects:

[0015] In the first technical solution and related embodiments, the upper achieves dual enhancement of protection and breathability, ensuring the safety and health of the wearer, while also ensuring the comfort and durability of the footwear, meeting the diverse needs of modern consumers for footwear products. By arranging a protective layer at a position close to the foot of the upper body, which is woven from a material with good puncture resistance and cut resistance, the risk of the upper being cut or punctured is effectively reduced. The upper body is formed by interweaving and weaving a plurality of TPU (thermoplastic polyurethane) fibers, forming at least one layer of TPU yarn arrangement layer. The winding gaps formed between these fibers and the grid structure of the protective layer greatly promote air circulation, effectively relieve the stuffiness of the feet, and ensure continuous breathable comfort. The TPU yarn is fixed by hot melt pressing at the overlapping position, which greatly enhances the overall structural stability of the upper, prevents deformation and wear that may occur during long-term wear or high-intensity activities, thereby extending the service life of the upper. Using TPU yarn and its interwoven weaving technology, this upper provides the necessary protection and breathability while still maintaining a lightweight texture, reducing the weight of the shoe body and further enhancing the wearing comfort experience.

[0016] In the second technical solution and related embodiments, carbon fiber is known for its high strength and high modulus properties, which makes the carbon fiber mesh layer woven from it have extremely high protective performance. It can effectively prevent the upper from being cut, punctured or other forms of physical damage, providing protection for the wearer's feet. Although the carbon fiber mesh layer has excellent protective performance, it still maintains good air permeability. This is because the mesh structure woven from carbon fiber allows air to flow freely, thereby reducing the stuffiness of the feet and improving the comfort of wearing. The carbon fiber mesh layer not only has excellent protective and breathable properties, but also has excellent structural stability due to its high strength characteristics. Even in the case of long-term wear or high-intensity activities, it can maintain the shape and structure of the upper and reduce deformation and wear. The carbon fiber material itself has the characteristics of lightness, which allows the mesh layer woven from it to provide strong protection while maintaining the light texture of the upper.

[0017] In the third technical solution and related embodiments, the manufacturing process and performance of the upper are further improved by adopting TPU yarn designs with different melting points. The melting point of the first TPU wire is lower than that of the second TPU wire, so that during the hot melt pressing process, the first TPU wire can be melted first and firmly bonded to the second TPU wire. This layered melting characteristic ensures a tighter and more uniform bond between the wires, and improves the stability and durability of the overall structure. The first TPU wire is spirally wound around the second TPU wire, which not only enhances the physical strength of the upper and resists external pressure and impact, but also retains the necessary flexibility, ensuring that the upper can adapt to the natural curvature of the foot and improves wearing comfort. By controlling the reaction order of TPU wires with different melting points during the hot pressing process, the hot pressing conditions can be adjusted more finely, which not only ensures the bonding effect, but also avoids damage to the material properties caused by excessive heating, thereby improving production efficiency and ensuring product quality.

[0018] In the third technical solution and related embodiments, since the melting point of the first TPU line is relatively low, in the range of 90°C-100°C, it can be more easily hot-melt pressed with the second TPU line by local heating. The second TPU line has a higher melting point, in the range of 160°C-180°C, which means it has better heat resistance and stability. Therefore, even at higher temperatures or pressures, the second TPU line can still maintain its original structure and performance, providing durable protective performance for the upper. By selecting TPU lines with different melting points and hot-melt pressing during the processing process, it can be ensured that the upper has higher durability while remaining light and flexible. This design enables the upper to withstand the wear and impact caused by long-term wear and high-intensity activities.

[0019] In the fifth technical solution and related embodiments, the design of the soft layer and the antibacterial layer further enhances the protective performance of the upper. The soft layer is located between the protective layer and the antibacterial layer, which can effectively absorb and disperse the pressure of the foot, so that the wearer can feel more comfortable when walking or exercising. At the same time, the soft layer can also relieve foot fatigue and provide the wearer with a better wearing experience. The antibacterial layer directly contacts the instep, which can effectively inhibit the growth of bacteria and reduce the risk of foot odor and infection.

[0020] In the sixth technical solution and related embodiments, the bamboo charcoal fiber itself has natural antibacterial properties, and its antibacterial rate is as high as 94%, which is much higher than many other textile materials. This antibacterial property can effectively inhibit the growth of bacteria, reduce the risk of foot odor and infection, and provide a healthier and cleaner wearing environment for the wearer. The mesh layer structure of the bamboo charcoal fiber has good air permeability, which can promote air circulation and reduce the stuffiness of the feet. The bamboo charcoal fiber has good moisture absorption and perspiration wicking properties, which can quickly absorb the sweat produced by the feet and discharge it out of the shoes. This helps keep the feet dry and reduces the possibility of bacterial growth and foot discomfort.

[0021] In the seventh technical solution and related embodiments, since the antibacterial layer contacts the instep, the cotton material is known for its soft and skin-friendly properties, and coating it on the surface of the bamboo charcoal fiber can further improve the comfort and fit of the upper. This allows the upper to provide the wearer with a softer and more comfortable touch while maintaining protection and breathability, reducing the discomfort caused by long-term wear. The cotton material has good moisture absorption and perspiration wicking properties, and can quickly absorb sweat generated by the feet and discharge it out of the shoe through the breathable structure of the bamboo charcoal fiber. This combination further enhances the moisture absorption and perspiration wicking properties of the upper, helping to keep the feet dry and comfortable.

[0022] In the eighth technical solution and related embodiments, the foam material itself has a certain air permeability, and the design of the air-permeable mesh can greatly improve the air permeability of the upper. This helps the air flow in the shoe, reduces the stuffiness of the foot, and allows the wearer to stay comfortable in various environments. At the same time, the foam material has excellent cushioning and shock-absorbing properties, which can effectively reduce the impact and vibration of the foot during walking or exercise.

[0023] In the ninth technical solution and related embodiments, the shoe achieves the technical effect of simple structure, good air permeability and protective function by adopting a special upper material with protective and breathable properties, providing the wearer with a safer, more comfortable and healthier wearing experience. The upper body is woven back and forth with TPU wire, and the winding gap formed between the wires greatly improves the air permeability of the upper. At the same time, the protective layer and the antibacterial mesh are both set in a grid. After being compounded with the upper body, the high air permeability of the upper can still be maintained, so that good gas exchange can be carried out inside the shoe cavity, ensuring that the shoes can provide a more breathable and comfortable wearing experience when worn in summer. The protective layer in the upper is made of carbon fiber, which provides excellent protection for the upper with its high strength, high modulus and good corrosion resistance. Even in the case of cutting or puncture, the upper can be effectively prevented from being cut through, thereby protecting the wearer's foot safety. This feature makes the shoes particularly suitable for wearing in scenes such as production work or outdoor adventures that require protection. The soft layer is made of foam material with breathable mesh, which brings good air permeability, cushioning and shock absorption, softness and comfort to the protective and breathable upper. The antibacterial layer is made of bamboo charcoal fiber woven mesh layer, and the surface is also covered with cotton material. These materials have natural antibacterial properties, which can effectively inhibit the growth of bacteria, reduce the risk of foot odor and infection, and provide a healthier and cleaner wearing environment for the wearer.

[0037] See also Figures 1 to 5 ,like Figure 1 As shown, a protective and breathable upper comprises an upper body 1, a protective layer 2, a soft layer 3 and an antibacterial layer 4 connected in sequence. The protective layer 2 is compounded with the side of the upper body 1 close to the foot, the soft layer 3 and the antibacterial layer 4 are connected to the protective layer 2 in sequence, the antibacterial layer 4 contacts the foot surface, and the soft layer 3 is located between the protective layer 2 and the antibacterial layer 4.

[0038] The upper body 1, such as Figure 2 As shown, it is formed by weaving a plurality of TPU yarns 5 (thermoplastic polyurethane) in an interlaced manner to form at least one layer of TPU yarn 5 arrangement layer, each TPU yarn 5 is fixedly connected by hot-melt pressing at the overlapping position, and a breathable winding gap is formed between the TPU yarns 5 after weaving. Figure 5 As shown, the TPU yarn 5 includes a first TPU yarn 6 and a second TPU yarn 7, the first TPU yarn 6 is spirally wound on the second TPU yarn 7, and the melting point of the first TPU yarn 6 is lower than the melting point of the second TPU yarn 7. Specifically, the melting point of the first TPU yarn 6 is 90°C-100°C, and the melting point of the second TPU yarn 7 is 160°C-180°C.

[0039] In this embodiment, the manufacturing process and performance of the upper are improved by adopting the design of TPU yarns 5 with different melting points. The melting point of the first TPU wire 6 is lower than that of the second TPU wire 7, so that during the hot melt pressing process, the first TPU wire 6 can be preferentially melted and firmly bonded to the second TPU wire 7. This layered melting characteristic ensures a tighter and more uniform combination between the wires, and improves the stability and durability of the overall structure. The first TPU wire 6 is spirally wound around the second TPU wire 7, which not only enhances the physical strength of the upper and resists external pressure and impact, but also retains the necessary flexibility, ensuring that the upper can adapt to the natural curvature of the foot and improves wearing comfort. By controlling the reaction order of TPU wires with different melting points during the hot pressing process, the hot pressing conditions can be adjusted more finely, which not only ensures the bonding effect, but also avoids damage to the material properties caused by excessive heating, thereby improving production efficiency and ensuring product quality.

[0040] In this embodiment, since the first TPU wire 6 has a lower melting point, in the range of 90°C-100°C, it can be more easily hot-melt-bonded with the second TPU wire 7 by local heating. The second TPU wire 7 has a higher melting point, in the range of 160°C-180°C, which means it has better heat resistance and stability. Therefore, even at higher temperatures or pressures, the second TPU wire 7 can still maintain its original structure and performance, providing durable protection for the upper. By selecting TPU wires with different melting points and hot-melt-bonding during the processing, it can be ensured that the upper has higher durability while remaining light and flexible. This design enables the upper to withstand the wear and impact caused by long-term wear and high-intensity activities.

[0041] Protective layer 2, such as Figure 1As shown, the protective layer 2 is connected to the upper body 1, and the protective layer 2 is woven with a material having good puncture resistance and cutting resistance to protect the upper from being cut or punctured; the protective layer 2 has a breathable grid structure, and specifically, the protective layer 2 is a carbon fiber mesh layer woven from carbon fibers. Carbon fiber is known for its high strength and high modulus, which makes the carbon fiber mesh layer woven from it have extremely high protective performance. It can effectively prevent the upper from being cut, punctured or other forms of physical damage, and provide protection for the wearer's feet. Although the carbon fiber mesh layer has excellent protective performance, it still maintains good air permeability. This is because the mesh structure woven from carbon fibers allows air to circulate freely, thereby reducing the stuffiness of the feet and improving the comfort of wearing. The carbon fiber mesh layer not only has excellent protective and breathable properties, but also has excellent structural stability due to its high strength characteristics. Even in the case of long-term wear or high-intensity activities, it can maintain the shape and structure of the upper and reduce deformation and wear. The carbon fiber material itself is lightweight, which allows the mesh layer woven from it to provide strong protection while maintaining the light texture of the upper.

[0042] The soft layer 3 is connected to the protective layer 2, and the soft layer 3 is made of a foam material with a breathable mesh. The foam material itself has a certain air permeability, and the design of the breathable mesh can greatly improve the air permeability of the upper. This helps the air circulation in the shoe, reduces the stuffiness of the feet, and allows the wearer to stay comfortable in various environments. At the same time, the foam material has excellent cushioning and shock-absorbing properties, which can effectively reduce the impact and vibration of the feet during walking or exercise.

[0043] The antibacterial layer 4 is connected to the soft layer 3 and contacts the foot surface. Figure 3 As shown, the antibacterial layer 4 is a mesh layer woven with bamboo charcoal fiber 8. The bamboo charcoal fiber 8 itself has natural antibacterial properties, and its antibacterial rate is as high as 94%, which is much higher than many other textile materials. This antibacterial property can effectively inhibit the growth of bacteria, reduce the risk of foot odor and infection, and provide the wearer with a healthier and cleaner wearing environment. The mesh layer structure of the bamboo charcoal fiber 8 has good air permeability, which can promote air circulation and reduce the stuffiness of the feet. The bamboo charcoal fiber 8 has good moisture absorption and perspiration properties, which can quickly absorb sweat produced by the feet and discharge it out of the shoes. This helps to keep the feet dry and reduce the possibility of bacterial growth and foot discomfort. In this embodiment, Figure 4As shown, the surface of the bamboo charcoal fiber 8 is coated with cotton material 9. Since the antibacterial layer 4 contacts the instep, the cotton material 9 is known for its soft and skin-friendly properties. Coating it on the surface of the bamboo charcoal fiber 8 can further improve the comfort and fit of the upper. This allows the upper to provide the wearer with a softer and more comfortable touch while maintaining protection and breathability, reducing the discomfort caused by long-term wear. The cotton material 9 has good moisture absorption and perspiration wicking properties, and can quickly absorb sweat generated by the foot and discharge it out of the shoe through the breathable structure of the bamboo charcoal fiber 8. This combination further enhances the moisture absorption and perspiration wicking properties of the upper, helping to keep the foot dry and comfortable.

[0044] In this embodiment, the design of the soft layer 3 and the antibacterial layer 4 further enhances the protective performance of the upper. The soft layer 3 is located between the protective layer 2 and the antibacterial layer 4, which can effectively absorb and disperse the pressure of the foot, so that the wearer can feel more comfortable when walking or exercising. At the same time, the soft layer 3 can also relieve foot fatigue and provide the wearer with a better wearing experience. The antibacterial layer 4 directly contacts the instep, which can effectively inhibit the growth of bacteria and reduce the risk of foot odor and infection.

[0045] In this embodiment, the upper achieves dual enhancement of protection and breathability, ensuring the safety and health of the wearer, while also ensuring the comfort and durability of the footwear, meeting the diverse needs of modern consumers for footwear products. By arranging a protective layer 2 near the foot of the upper body 1, which is woven from a material with good puncture resistance and cutting resistance, the risk of the upper being cut or punctured is effectively reduced. The upper body 1 is formed by a plurality of TPU yarns 5 in an interwoven and woven manner, forming at least one layer of TPU yarn 5 arrangement layer. The winding gaps formed between these fibers and the grid structure of the protective layer 2 greatly promote air circulation, effectively relieve the stuffiness of the foot, and ensure continuous breathable comfort. The TPU yarn 5 is fixed by hot-melt pressing at the overlapping position, which greatly enhances the overall structural stability of the upper, prevents deformation and wear that may occur during long-term wear or high-intensity activities, thereby extending the service life of the upper. Using TPU yarn 5 and its interwoven weaving technology, this upper provides the necessary protection and breathability while still maintaining a lightweight texture, reducing the weight of the shoe body and further enhancing the wearing comfort experience.

[0046] A shoe comprises a sole and an upper mounted on the sole, wherein the upper adopts the above-mentioned protective and breathable upper. The shoe achieves the technical effect of simple structure, good breathability and protective function by adopting a special upper material with protective and breathable properties, and provides a safer, more comfortable and healthier wearing experience for the wearer. The upper body 1 is woven by winding TPU yarn 5 back and forth, and the winding gap formed between the threads greatly improves the air permeability of the upper. At the same time, the protective layer 2 and the antibacterial mesh cloth are both arranged in a grid, and after being compounded with the upper body 1, the high air permeability of the upper can still be maintained, so that the inside of the shoe cavity can have good gas exchange, ensuring that the shoe can provide a more breathable and comfortable wearing experience when worn in summer. The protective layer 2 in the upper is made of carbon fiber, and the carbon fiber provides excellent protection for the upper with its high strength, high modulus and good corrosion resistance. Even in the case of cutting or puncture, the upper can be effectively prevented from being cut through, thereby protecting the safety of the wearer's feet. This feature makes the shoe particularly suitable for wearing in scenes such as production work or outdoor adventures that require protection. The soft layer 3 is designed with a foam material with a breathable mesh, which brings good air permeability, cushioning and shock absorption effects, softness and comfort to the protective and breathable upper. The antibacterial layer 4 is a mesh layer woven with bamboo charcoal fiber 8, and the surface is also covered with cotton material 9. These materials have natural antibacterial properties, can effectively inhibit bacterial growth, reduce the risk of foot odor and infection, and provide a healthier and cleaner wearing environment for the wearer.
