[0014] The tenth technical solution is based on any one of the first to ninth technical solutions, wherein a shoe comprises a sole and an upper mounted on the sole, and the upper adopts the above-mentioned breathable and waterproof upper.
[0015] 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:
[0016] In the first technical solution and related embodiments, the upper base layer adopts a unique TPU core-spun yarn back and forth interweaving weaving process to form at least one layer of TPU core-spun yarn arrangement layer. The winding gap formed therein promotes air circulation, effectively relieves the stuffiness of the feet, and ensures lasting breathable comfort; the inner layer close to the foot side integrates a breathable and waterproof layer, which not only blocks external moisture from penetrating into the shoe through the winding gap and maintains the dry state of the shoe cavity, but also ensures good air permeability, which complements the air permeability of the upper base layer to ensure the overall air exchange freedom; the upper design takes into account the characteristics of breathability and waterproofness, which is suitable for the refreshing needs in high temperature environments in summer, and also meets the waterproof protection in rainy seasons or humid environments, effectively isolating rainwater intrusion and ensuring the continuous dryness and health of users' feet; the waterproof design also provides users with additional protection against accidental liquid splashes, etc., which enhances the practical value and safety performance of shoes in a variety of daily and special situations.
[0017] In the second technical solution and related embodiments, the breathable waterproof layer adopts a microporous film structure of TPU material, and TPU microporous membrane is selected as the core waterproof material. This material is derived from advanced thermoplastic polyurethane. Its uniqueness lies in its fine and evenly distributed microporous structure, which allows air and water vapor molecules to pass freely, while forming an effective barrier to liquid water, achieving a balance between breathability and waterproofness; the application of TPU microporous membrane not only effectively isolates external moisture and humidity from invading the inside of the shoe cavity, maintains the continuous dryness and hygiene of the shoe environment, but also ensures sufficient air circulation, effectively alleviates the problems of moisture and overheating of the feet, and creates a refreshing and comfortable microenvironment inside the shoe for the wearer.
[0018] In the third technical solution and related embodiments, in the breathable and waterproof upper, the performance and durability of the upper are further improved by the double-layer TPU core-spun yarn structure. Specifically, the upper base adopts a double-layer TPU wire structure - the first TPU wire is the core support, and the melting point ranges from 160°C to 180°C, which ensures the structural strength and stability of the upper at high temperatures; the second TPU wire is tightly attached to the outside of the first TPU wire in a coated form, and its melting point is low, set in the range of 90°C to 100°C. This design can first melt during the hot pressing process, tightly wrap and firmly bond the first TPU wire, forming a stable and layered composite structure. Such a design not only strengthens the structural stability of the upper and prevents deformation or wear under long-term use, but also optimizes the hot melt pressing process by combining TPU wires with different melting points, improves production efficiency and combination accuracy, ensures the uniformity and durability of the entire upper structure, and provides the wearer with a more solid, durable and comfortable wearing experience.
[0019] In the fourth technical solution and related embodiments, a third TPU thread is implanted at the intersection and overlap nodes of the TPU core-spun yarn as a fixed thread. This fixed thread not only plays a positioning role to ensure the exact position of each TPU core-spun yarn in the upper layout, but also tightly combines with the surrounding TPU core-spun yarn during the hot pressing process to create a reinforcement structure similar to a locking mechanism; this structure, like "locking", greatly enhances the binding strength between the TPU core-spun yarns and the stability of the overall structure. The addition of the third TPU thread effectively increases the hot pressing bonding points, further consolidates the interconnection of the TPU core-spun yarn, and the connection between the threads remains firm in the face of external tension; through the integration of the third TPU thread, not only the ability of the upper to withstand impact is greatly improved, but also the wear resistance and durability of long-term wear are significantly improved, ensuring the high performance and long service life of the footwear product in intense exercise or long-term use.
[0020] In the fifth technical solution and related embodiments, a third TPU wire with a melting point also set in the range of 90°C to 100°C is used as a fixed wire. This choice matches the melting point range of the second TPU wire, the covering wire in the TPU core-spun yarn. In the hot pressing step, the third TPU wire can quickly respond to heat energy and melt, and then tightly fuse with the second TPU wire to form a high-strength connection node. This design makes full use of the low melting point characteristics. Even at relatively low temperatures, the fixed wire can show good fluidity, combined with the TPU core-spun yarn arrangement layer, fix the position of the TPU core-spun yarn, and effectively prevent the dislocation or separation between fibers.
[0021] In the sixth technical solution and related embodiments, in the design of the breathable and waterproof upper, the antibacterial and deodorizing layer and the cool and comfortable layer are added to further improve the overall performance of the upper. The antibacterial and deodorizing layer is located between the cool and comfortable layer and the waterproof layer, which can effectively inhibit the growth of bacteria and reduce the odor caused by long-term wear. This design ensures the cleanliness and hygiene inside the shoe and provides users with a healthier and more comfortable wearing environment. The cool and comfortable layer directly contacts the instep, which can quickly conduct the heat of the foot, reduce the temperature of the foot, and bring a cool and comfortable wearing experience to the user. This design is particularly practical in hot weather or when walking for a long time, and can significantly reduce the stuffiness of the feet.
[0022] In the seventh technical solution and related embodiments, the provision of airflow channels effectively improves the air permeability of the upper. These channels promote the free circulation of air between the cool and comfortable layer and the antibacterial and deodorizing layer, accelerate the discharge process of heat and moisture in the shoe, and ensure the lasting dryness and high comfort of the shoe cavity environment. Specifically, the provision of airflow channels optimizes the air circulation path, significantly improves the heat dissipation efficiency of the cool and comfortable layer, effectively and quickly takes away the heat from the feet, and significantly alleviates the feeling of stuffiness when wearing. As a direct result, the dry environment in the shoe not only improves the immediate wearing comfort, but also indirectly inhibits the reproduction of bacteria, because bacteria are more likely to breed in a humid environment. In this way, a higher level of hygiene and freshness is maintained in the shoe. At the same time, the antibacterial and deodorizing layer can maintain its dry state for a long time thanks to the continuous ventilation brought by the airflow channel, further enhancing its antibacterial and deodorizing functionality, effectively controlling the generation of odor, and maintaining the cleanliness and health of the environment in the shoe.
[0023] In the eighth technical solution and related embodiments, the cool and comfortable layer is carefully woven with ice silk cool fibers. With its good thermal conductivity, this material can instantly transfer heat energy from the skin surface, giving the wearer an immediate cool feeling, especially in high temperature or long-distance walking scenarios, significantly relieving the stuffiness of the feet and greatly improving the wearing comfort. The ice silk cool fibers, with their delicate and soft texture, gently fit the skin of the feet, effectively reduce friction and discomfort, and further optimize the softness and comfort of the wearing experience.
[0024] In the ninth technical solution and related embodiments, the antibacterial and deodorizing layer uses high-performance bamboo charcoal fiber material. The material has excellent antibacterial and deodorizing properties, can effectively curb the growth of various bacteria, and significantly reduce the generation of odor in the shoes. This is due to the strong adsorption performance of bamboo charcoal fiber, which can effectively capture and decompose harmful substances and odor molecules in the shoe cavity. The fabric structure formed by bamboo charcoal fiber is both tight and breathable and absorbent, which promotes the natural circulation of air in the shoes, further inhibits bacterial reproduction and odor generation, and also promotes the natural breathing of the foot skin, bringing a more refreshing and healthy wearing experience to the wearer.
[0025] In the tenth technical solution and related embodiments, the upper structure of the present application integrates a base layer woven with TPU core-spun yarn to ensure structural stability and air permeability, the breathable and waterproof layer constructed with TPU microporous membrane realizes dual protection of air permeability and watertightness, the cool and comfortable layer composed of ice silk cool fiber brings an instant cool experience, and the antibacterial and deodorizing layer made of bamboo charcoal fiber effectively maintains the hygiene inside the shoe. In addition, the airflow channel further optimizes the overall air permeability performance, and under the joint action, multiple functions of air permeability, waterproofness, cool and comfortable feeling, and antibacterial and deodorizing are realized, creating a healthy, comfortable and multifunctional wearing environment for the wearer.

[0038] See also Figures 1 to 4 ,like Figure 1 As shown, a breathable and waterproof upper comprises an upper base layer 1, a breathable and waterproof layer 2, an antibacterial and deodorizing layer 3 and a cool and comfortable layer 4 which are connected in sequence to meet the multiple requirements of breathability, waterproofness, cool and comfortable feeling and antibacterial and deodorizing.
[0039] Upper base 1, such as Figure 2As shown, it is composed of a plurality of TPU core-spun yarns 5, which are fibers made of thermoplastic polyurethane (Thermoplastic Polyurethane) material. TPU is a polymer material with excellent elasticity and wear resistance. It also has multiple properties such as oil resistance, chemical resistance, and low temperature resistance. The upper base layer 1 is woven by a plurality of TPU core-spun yarns 5 in an interlaced manner to form at least one layer of TPU core-spun yarn 5 arrangement layer. Each TPU core-spun yarn 5 is fixedly connected at the overlapping position by hot melt pressing technology, and a breathable winding gap is formed between the TPU core-spun yarns 5 after weaving.
[0040] The TPU core-spun yarn 5 includes a first TPU line 6, a second TPU line 7 and a third TPU line 8. Figure 3 As shown, the second TPU line 7 is coated on the outside of the first TPU line 6, wherein the melting point of the first TPU line 6 ranges from 160°C to 180°C, and the melting point of the second TPU line 7 ranges from 90°C to 100°C. In the breathable and waterproof upper, the performance and durability of the upper are further improved by the double-layer TPU core-spun yarn 5 structure. Specifically, the upper base layer 1 adopts a double-layer TPU line structure - the first TPU line 6 is the core support, and the melting point ranges from 160°C to 180°C, which ensures the structural strength and stability of the upper at high temperatures; the second TPU line 7 is tightly attached to the outside of the first TPU line 6 in a coated form, and its melting point is relatively low, set in the range of 90°C to 100°C. This design can melt first during the hot pressing process, tightly wrap and firmly bond the first TPU line 6, forming a stable and layered composite structure. This design not only enhances the structural stability of the upper and prevents deformation or wear under long-term use, but also the combination strategy of TPU lines with different melting points optimizes the hot melt pressing process, improves production efficiency and bonding accuracy, ensures the uniformity and durability of the entire upper structure, and provides the wearer with a more sturdy, durable and comfortable wearing experience.
[0041] The third TPU line 8, such as Figure 4As shown, it is located at the overlapping position between the TPU core-spun yarns 5, and the third TPU thread 8 is a fixing thread used to prevent the TPU core-spun yarns 5 from sliding or separating. The melting point of the third TPU thread 8 is set to 90°C-100°C. A third TPU line 8 is implanted as a fixed line at the intersection and overlap nodes of the TPU core-spun yarn 5. This fixed line not only plays a positioning role to ensure the exact position of each TPU core-spun yarn 5 in the upper layout, but also is tightly combined with the surrounding TPU core-spun yarn 5 during the hot pressing process to create a reinforcement structure similar to a locking mechanism. This structure, like "locking", greatly enhances the binding strength between the TPU core-spun yarns 5 and the stability of the overall structure. The addition of the third TPU line 8 effectively increases the hot pressing bonding points, further consolidates the interconnection of the TPU core-spun yarn 5, and the connection between the lines remains firm in the face of external tension. The integration of the third TPU line 8 not only greatly improves the ability of the upper to withstand impact, but also significantly improves the wear resistance and durability of long-term wear, ensuring the high performance and long service life of the footwear product in intense exercise or long-term use. In this embodiment, the third TPU wire 8 with a melting point also set in the range of 90°C to 100°C is used as the fixed wire. This choice matches the melting point range of the second TPU wire 7 of the covering wire in the TPU core-spun yarn 5. In the hot pressing step, the third TPU wire 8 can quickly respond to heat energy and melt, and then tightly fuse with the second TPU wire 7 to form a high-strength connection node. This design makes full use of the low melting point characteristics. Even at a relatively low temperature, the fixed wire can show good fluidity, combined with the arrangement layer of the TPU core-spun yarn 5, fix the position of the TPU core-spun yarn 5, and effectively prevent the dislocation or separation between fibers.
[0042] Breathable waterproof layer 2, such as Figure 1 As shown, it is located on the side of the upper base layer 1 close to the foot, and the breathable waterproof layer 2 is used to prevent moisture from penetrating into the inner cavity of the shoe through the winding gap, while maintaining the air permeability of the inner cavity of the shoe. Specifically, the breathable waterproof layer 2 is a microporous film structure made of TPU material. The breathable waterproof layer 2 adopts a microporous film structure made of TPU material, and selects TPU microporous membrane as the core waterproof material. This material is derived from advanced thermoplastic polyurethane. Its uniqueness lies in its fine and evenly distributed microporous structure, which allows air and water vapor molecules to pass freely, while forming an effective barrier to liquid water, achieving a balance between breathability and waterproofness; the application of TPU microporous membrane not only effectively isolates external moisture and humidity from invading the inside of the shoe cavity, maintains the continuous dryness and hygiene of the shoe environment, but also ensures sufficient air circulation, effectively alleviates the dampness and overheating problems of the feet, and creates a refreshing and comfortable microenvironment in the shoe for the wearer.
[0043] The cooling and comfort layer 4, which contacts the instep, is composed of cooling fibers woven from ice silk material. The cooling and comfort layer 4 is carefully woven from ice silk cooling fibers. With its good thermal conductivity, this material can instantly transfer heat energy from the skin surface, giving the wearer an immediate cool feeling, especially in high temperature or long-distance walking scenarios, significantly relieving the stuffiness of the feet and greatly improving the wearing comfort. The ice silk cooling fibers, with their delicate and soft texture, gently fit the skin of the feet, effectively reducing friction and discomfort, and further optimizing the softness and comfort of the wearing experience.
[0044] The antibacterial and deodorizing layer 3 is located between the cool and comfortable layer 4 and the waterproof layer. The antibacterial and deodorizing layer 3 is woven from bamboo charcoal fibers. The antibacterial and deodorizing layer 3 uses high-performance bamboo charcoal fiber materials. The antibacterial and deodorizing properties of this material are excellent, which can effectively curb the growth of various bacteria and significantly reduce the generation of odor in the shoes. This is due to the strong adsorption properties of bamboo charcoal fibers, which can effectively capture and decompose harmful substances and odor molecules in the shoe cavity. The fabric structure formed by bamboo charcoal fibers is both compact and breathable and absorbent, which promotes the natural circulation of air in the shoes, further inhibits bacterial reproduction and odor generation, and also promotes the natural breathing of the foot skin, bringing a more refreshing and healthy wearing experience to the wearer.
[0045] In this embodiment, in the design of the breathable and waterproof upper, the antibacterial and deodorizing layer 3 and the cool and comfortable layer 4 are added to further improve the comprehensive performance of the upper. The antibacterial and deodorizing layer 3 is located between the cool and comfortable layer 4 and the waterproof layer, which can effectively inhibit the growth of bacteria and reduce the odor caused by long-term wear. This design ensures the cleanliness and hygiene inside the shoe and provides users with a healthier and more comfortable wearing environment. The cool and comfortable layer 4 directly contacts the instep, which can quickly conduct the heat of the foot, reduce the temperature of the foot, and bring a cool and comfortable wearing experience to the user. In hot weather or when walking for a long time, this design is particularly practical and can significantly reduce the stuffiness of the foot.
[0046] A number of airflow channels 9 are provided between the cool and comfortable layer 4 and the antibacterial and deodorizing layer 3. Specifically, the airflow channels 9 pass through the cool and comfortable layer 4 and the antibacterial and deodorizing layer 3 from the instep to reach the waterproof and breathable layer. The provision of the airflow channels 9 effectively improves the air permeability of the upper. These channels promote the free circulation of air between the cool and comfortable layer 4 and the antibacterial and deodorizing layer 3, accelerate the discharge process of heat and moisture in the shoe, and ensure the lasting dryness and high comfort of the shoe cavity environment. Specifically, the provision of the airflow channels 9 optimizes the air circulation path, significantly improves the heat dissipation efficiency of the cool and comfortable layer 4, effectively and quickly takes away the heat from the foot, and significantly alleviates the feeling of stuffiness when wearing. As a direct result, the dry environment inside the shoe not only improves the immediate wearing comfort, but also indirectly inhibits the reproduction of bacteria, because bacteria are more likely to breed in a humid environment. In this way, a higher level of hygiene and freshness is maintained inside the shoe. At the same time, the antibacterial and deodorizing layer 3 can maintain its dry state for a long time thanks to the continuous ventilation brought by the air flow channel 9, further enhancing its antibacterial and deodorizing functions, effectively controlling the generation of odor, and maintaining the cleanliness and health of the environment inside the shoe.
[0047] In this embodiment, the upper base layer 1 adopts a unique TPU core-spun yarn 5 interweaving and weaving process to form at least one layer of TPU core-spun yarn 5 arrangement layer, and the winding gap formed therein promotes air circulation, effectively relieves the stuffiness of the feet, and ensures lasting breathable comfort; the inner layer close to the foot side integrates a breathable waterproof layer 2, which not only blocks external moisture from penetrating into the shoe through the winding gap, maintains the shoe cavity in a dry state, but also ensures good air permeability, which complements the air permeability of the upper base layer 1 to ensure the overall air exchange freedom; the upper design takes into account the characteristics of breathability and waterproofness, which is suitable for the refreshing needs in high temperature environments in summer, and also meets the waterproof protection in rainy seasons or humid environments, effectively isolating rainwater intrusion and ensuring the continuous dryness and health of the user's feet; the waterproof design also provides users with additional protection against accidental liquid splashes, etc., which enhances the practical value and safety performance of shoes in a variety of daily and special situations.
[0048] A shoe comprises a sole and an upper mounted on the sole, wherein the upper adopts the above-mentioned breathable and waterproof upper. The breathable and waterproof upper integrates a base layer woven with TPU core-spun yarn 5 to ensure structural stability and air permeability, a breathable and waterproof layer 2 constructed with a TPU microporous membrane realizes dual protection of air permeability and watertightness, a cool and comfortable layer 4 composed of ice silk cool fibers brings an instant cool experience, and an antibacterial and deodorizing layer 3 made of bamboo charcoal fibers effectively maintains the hygiene inside the shoe. In addition, the airflow channel 9 further optimizes the overall air permeability performance, and under the joint action, multiple functions of air permeability, waterproofness, cool and comfortable feeling, and antibacterial and deodorizing are realized, creating a healthy, comfortable and multifunctional wearing environment for the wearer.
[0049] The present application provides a breathable and waterproof upper and a shoe. The shoe made with the breathable and waterproof upper can effectively prevent water from entering the shoe cavity while maintaining air permeability, thereby improving the wearing experience of the user.
