[0013] In addition, the present utility model also provides technical solution nine: A shoe, which includes a sole, and the sole is compounded with a high-strength string silk shoe upper as described in any one of technical solutions one to eight.

[0014] From the above description of the present utility model, compared with the prior art, the present utility model has the following beneficial effects:

[0015] Technical solution one provides a high-strength string silk shoe upper. The shoe upper includes a shoe upper layer located on the outermost side. The shoe upper layer is formed by laying polyester yarns. The single-layer or multi-layer laying method can adjust the structural strength and air permeability of different positions of the shoe upper according to actual needs. The polyester yarn used in the shoe upper layer includes a core wire, and a polyester layer is coated outside the core wire. Among them, the core wire uses liquid crystal polymer fiber. Liquid crystal polymer fiber has the advantages of high strength and high modulus. As the core wire, it can significantly improve the structural strength of the shoe upper layer and is less likely to be pulled and broken. At the same time, liquid crystal polymer fiber also has the characteristic of light weight. As a component material of the shoe upper, it can reduce the overall weight of the shoe, which is beneficial to improving the wearing comfort of users. In addition, the coating layer outside the core wire is made of thermoplastic polyurethane material, which can protect the core wire and endow the shoe upper layer with good elasticity and shape retention ability, so that the shoe upper can adapt to the dynamic changes of the foot, has a better fitting effect, and can further improve the structural stability of the shoe upper layer.

[0016] In technical solution two, the polyester layer is an aliphatic thermoplastic polyurethane material. Since the molecular structure of the aliphatic thermoplastic polyurethane material does not contain benzene rings, it can effectively reduce chemical reactions caused by ultraviolet rays, thereby improving the yellowing resistance of the shoe upper layer.

[0017] In technical solution three, the waterproof layer is formed by a waterproof and breathable membrane made of polytetrafluoroethylene (PTFE) material, which provides excellent waterproof performance, prevents external moisture from entering the shoe, and at the same time maintains good air permeability to ensure that the feet are dry and comfortable. PTFE material also has good chemical resistance and high temperature resistance, further improving the comprehensive performance of the shoe upper.

[0018] In technical solution four, the health care layer is woven by magnetic fibers. The magnetic fibers can promote blood circulation in the feet, relieve fatigue, provide additional health care functions, and improve the comfort and health experience of the wearer.

[0019] In Technical Solution Five, co - blended spinning magnetic fibers or surface - coated magnetic fibers can be used, and different magnetic intensities and health care effects can be selected according to needs. The co - blended spinning magnetic fibers have good uniformity and stability, while the surface - coated magnetic fibers can provide a stronger magnetic effect to meet the needs of different users.

[0020] In Technical Solution Six, the wear - resistant layer is woven from liquid crystal polymer fibers, which further improves the wear - resistance and strength of the shoe upper and extends the service life of the shoes. At the same time, the liquid crystal polymer fibers have the characteristics of light weight and high strength, and will not increase the weight of the shoes, ensuring the portability of wearing.

[0021] In Technical Solution Seven, the accommodating part provides an additional storage space, which can be used to store functional materials such as spices or desiccants. The design of the volatilization holes can ensure that the smell of the internal functional materials can be effectively dissipated.

[0022] In Technical Solution Eight, the polyvinyl chloride (PVC) material has good wear - resistance and chemical resistance. By using the hot - pressing technology to fix the accommodating part on the shoe upper layer, its firmness and stability can be ensured, and at the same time, it does not affect the overall aesthetics and service performance of the shoe upper.

[0023] In Technical Solution Nine, a shoe is provided, which adopts the above - mentioned high - strength string - type shoe upper, has higher structural strength, and can better adapt to intense application scenarios. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] Embodiment 1

[0037] Refer to Figure 1 An embodiment of the present invention provides a high-strength string wire upper surface 1, which can be compounded to a prefabricated sole by means of bonding, hot melting or sewing, and the two cooperate to form a shoe.

[0038] Reference Figure 2 The high-strength string silk upper 1 provided in this embodiment includes an upper layer 1 located on the outermost side, and a waterproof layer 12, a health layer 13 and a wear-resistant layer 14 located on the inner side of the upper layer 1 and arranged in sequence from the outside to the inside.

[0039] The upper layer 1 is formed by laying the polyester yarn in a single layer and / or multiple layers according to the shape of the upper 1. Specifically, when forming the upper layer 1, a laying range can be first defined according to the shape of the upper 1, and then the polyester yarn can be laid on a plane according to a predetermined direction, wherein if a certain part of the upper 1 needs to have higher strength, the polyester yarn can be laid in multiple layers at the corresponding part, and if a certain part of the upper 1 needs to have better air permeability, the polyester yarn can be laid in a single layer at the corresponding part, and at the position where multiple layers are laid, the overlapping polyester yarns can be connected by hot-melt pressing. At the rest of the positions, if the polyester yarns overlap during the laying process, the connection relationship can also be formed by hot-melt pressing at the overlapping positions. At the edge of the upper 1, the polyester yarns arranged in other directions on the inner side can be connected as a whole by the polyester yarns extending along the edge of the upper 1. Through this laying method, the polyester yarns are wound back and forth, and a mesh structure can be formed through the nodes at the overlapping positions, thereby providing higher strength and stability.

[0040] Among them, refer to Figure 3 , the polyester yarn includes an inner core wire 112, and a polyester layer 111 is coated on the outer surface of the inner core wire 112, the inner core wire 112 is a liquid crystal polymer fiber 141, and the polyester layer 111 is a thermoplastic polyurethane material. The inner core wire 112 uses a liquid crystal polymer fiber 141, that is, an LCP fiber. In this embodiment, the LCP fiber produced by Shanghai Pulit Company is used as a raw material. LCP fibers have very high tensile strength and modulus, which means that they can withstand greater tension and pressure without being easily broken or deformed. This characteristic makes the upper 1 more durable and long-lasting during use and not easy to be damaged. At the same time, the density of LCP fibers is low, so the weight is light. This means that the upper 1 made of this fiber will not significantly increase the weight of the shoe while providing sufficient strength, ensuring the comfort and lightness of wearing. In addition, LCP fibers have low hygroscopicity, which can reduce the ability of the shoe to absorb moisture, thereby keeping the inside of the shoe dry and enhancing the comfort of wearing. In addition, LCP fibers have high dimensional stability when heated or stressed, and are not easy to deform. This enables the upper 1 to maintain its shape and performance under various environmental conditions.

[0041] The polyester layer 111 is made of thermoplastic polyurethane material, especially aliphatic thermoplastic polyurethane material. Since the molecular structure of the aliphatic thermoplastic polyurethane material does not contain benzene rings, it can effectively reduce chemical reactions caused by ultraviolet rays, thereby improving the yellowing resistance of the upper layer 1; moreover, instead of using pure thermoplastic polyurethane threads directly as the yarn for manufacturing the upper layer 1, the aliphatic thermoplastic polyurethane material is used as a coating layer to coat the outer core thread 112, which not only enables the polyester yarn to have good mechanical properties and weather resistance of thermoplastic polyurethane, but also improves the structural stability and waterproofness of the upper layer 1.

[0042] Refer to Figure 2 , on the inner side of the upper layer 1, a waterproof layer 12 is adhesively provided. The waterproof layer 12 is formed by pasting a waterproof and breathable membrane on the inner side of the upper layer 1, and the waterproof and breathable membrane is made of polytetrafluoroethylene material. Setting the waterproof layer 12 on the inner side of the upper layer 1 can provide a base for the waterproof layer 12 to be set and can protect the upper layer 1 to prevent the waterproof layer 12 from falling off. The waterproof layer 12 itself is made of polytetrafluoroethylene material, which has a unique microporous structure that can allow water vapor to pass through but can effectively block liquid water. Therefore, this waterproof layer 12 can ensure waterproofness while maintaining the breathability of the upper 1. When the user wears the shoes, the moisture inside the shoes can be quickly discharged, keeping the feet dry and improving the wearing comfort. The waterproof and breathable membrane is fixed on the inner side of the upper layer 1 by pasting or methods such as hot pressing and sewing to ensure its close combination with the upper layer 1 and is not easy to fall off or shift.

[0043] On the inner side of the waterproof layer 12, a health care layer 13 is adhesively provided. The health care layer 13 is formed by cross-weaving magnetic fibers. The magnetic fibers can be selected from blended spinning magnetic fibers or surface-coated magnetic fibers. The health care layer 13 is made of magnetic fibers, and these magnetic fibers can promote blood circulation in the feet and relieve fatigue through the action of the magnetic field, providing the effect of foot health care. Among them, the magnetic fibers can be selected as blended spinning magnetic fibers. Blended spinning magnetic fibers are fibers made by mixing magnetic materials with other fiber materials during the fiber manufacturing process. This kind of fiber has good uniformity and stability, and the magnetic materials are evenly distributed in the fiber to ensure the continuity and stability of the magnetic field action. Or, the magnetic fibers can be selected as surface-coated magnetic fibers. Surface-coated magnetic fibers are fibers made by coating a layer of magnetic material on the fiber surface. The magnetic effect of this kind of fiber is stronger, and the magnetic materials are concentrated on the fiber surface, which can provide a more significant magnetic field action. It is suitable for the health care layer 13 that requires a stronger magnetic effect. When fixing the health care layer 13, it can be sewn on the upper layer 1 through the waterproof layer 12.

[0044] On the inner side of the health care layer 13, a wear-resistant layer 14 is adhesively provided. The wear-resistant layer 14 is formed by cross-weaving liquid crystal polymer fibers 141. Specifically, refer to Figure 4, which shows the structure of the wear-resistant layer 14. Since the wear-resistant layer 14 is made of liquid crystal polymer fibers 141, after being woven into fiber cloth pieces, it has good wear resistance. Setting it on the innermost layer of the shoe upper 1 can protect the shoe upper 1 when the shoe upper 1 is rubbed by the foot.

[0045] In addition, referring to Figure 1 , a receiving member 3 is further provided on the outer surface of the shoe upper 1 layer. A receiving cavity is formed in the receiving member 3 or a receiving cavity is formed in cooperation with the shoe upper 1 layer. The receiving cavity has an opening, and the receiving member 3 is provided with a volatilization hole 2 communicating with the receiving cavity. At the same time, the receiving member 3 is made of polyvinyl chloride material, and it is hot-pressed on the shoe upper 1 layer. When wearing, functional materials such as mosquito repellent tablets and scented tablets can be put into the receiving cavity from the opening of the receiving cavity. Then, during the wearing process, the smell of these functional materials will disperse from the volatilization hole 2 on the receiving member 3, thereby achieving corresponding effects. The receiving member 3 is made of polyvinyl chloride material, that is, PVC material. PVC material has excellent wear resistance, chemical resistance and waterproofness, which can protect the functional materials inside it from the influence of the external environment. At the same time, the receiving member 3 is fixed to the shoe upper 1 layer through hot-pressing technology, which can tightly combine the receiving member 3 with the shoe upper 1 layer and ensure the durability and reliability of the receiving member 3 during use.
