Description

Technical Field

[0001] The utility model relates to the technical field of shoes, and particularly relates to a double-material string silk shoe upper and a shoe. Background Art

[0002] Fly-knitted, Jacquard or woven shoe uppers are often used in the market. Due to the limitation of the knitting method, such shoe uppers have insufficient air permeability and cannot achieve full-air permeability of the shoe upper. For this reason, Chinese Patent Application No. 202222565289.4 proposes a new type of string silk embroidered shoe upper, which forms a row of lines by winding the yarn made of thermoplastic polyurethane material back and forth, and composes the shoe upper by hot pressing and combining at the intersection or coincidence point of the yarns. However, in actual use, the connection between the yarns of the shoe upper is not firm enough, and the joint position of the yarns is prone to falling off, resulting in damage to the shoe upper. Content of the Utility Model

[0003] The purpose of the utility model is to overcome the above-mentioned defects or problems in the background art, and provide a double-material string silk shoe upper and a shoe, in which the connection between the shoe upper yarns is firm and the joint is not easy to fall off.

[0004] To achieve the above purpose, the utility model adopts the following technical solutions:

[0005] Technical Solution 1: A double-material string silk shoe upper, which includes a shoe upper layer located on the outermost side. The shoe upper layer is formed by laying polyester yarns in a single layer and / or multiple layers according to the shape of the shoe upper. The polyester yarn includes a core wire, and a polyester layer is coated on the core wire. The core wire is made of thermoplastic polyester elastomer material, and the polyester layer is made of thermoplastic polyurethane elastomer material. At the overlapping positions where the polyester yarns are laid in multiple layers, the polyester layers on the outside are integrally bonded by hot pressing, and the core wires of the two are connected.

[0006] Technical Solution 2 based on Technical Solution 1: The polyester layer is made of aliphatic thermoplastic polyurethane elastomer material.

[0007] Technical Solution 3 based on Technical Solution 2: The melting point range of the core wire is 160°C - 180°C, and the melting point range of the polyester layer is 90°C - 100°C.

[0008] Technical Solution 4 based on Technical Solution 1: It further includes a waterproof layer located inside the shoe upper layer. The waterproof layer is formed by pasting a waterproof and breathable film on the inside of the shoe upper layer. The waterproof and breathable film is made of polytetrafluoroethylene material.

[0009] Technical Solution 5 based on Technical Solution 4: It further includes an antibacterial layer located inside the waterproof layer. The antibacterial layer is formed by warp and weft knitting of bamboo charcoal fibers.

[0010] Technical solution six based on technical solution five: A plurality of ventilation holes are provided through the bamboo charcoal fiber layer in the thickness direction.

[0011] Technical solution seven based on technical solution six: It further includes a contact layer located inside the antibacterial layer. The contact layer is formed by warp and weft knitting of contact yarns. The contact yarns include ramie fibers and cotton fibers coated on the outer sides of the ramie fibers. The cotton fibers are spirally wound around the corresponding ramie fibers.

[0012] Technical solution eight based on technical solution seven: The antibacterial layer is stitched and connected to the shoe surface layer, and the contact layer is stitched and connected to the antibacterial layer.

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

[0014] As can be seen 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 double-material string silk shoe surface. The shoe surface includes a shoe surface layer located on the outermost side. The shoe surface 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 surface according to actual needs. The polyester yarns used in the shoe surface layer include inner core wires, and a polyester layer is coated on the outer side of the inner core wires. Among them, the inner core wire is made of thermoplastic polyester elastomer material. The thermoplastic polyester elastomer material has very excellent mechanical properties, with high tensile strength and elastic modulus. As the inner core wire, it can provide better structural strength for the polyester yarns, avoiding the shoe surface layer from breaking and being damaged due to intense exercise. At the same time, a polyester layer is coated on the outer side of the inner core wire. The polyester layer is made of thermoplastic polyurethane elastomer material, which has high elasticity and wear resistance, can protect the inner core wire, and can improve the overall wear resistance of the polyester yarns. And, in this technical solution, during the molding process of the shoe surface layer, due to the different melting point ranges of the thermoplastic polyester elastomer and the thermoplastic polyurethane elastomer, a certain temperature can be used for hot pressing at the overlapping positions of the polyester yarns, so that the polyester layer melts while the inner core wire remains in a solid state. After cooling, the overlapping polyester yarns can be connected into one body through the polyester layer;

[0016] In similar shoe uppers in the prior art, since only one material, thermoplastic polyurethane elastomer, is used, it is often difficult to accurately determine the appropriate hot pressing time, resulting in too low a welding degree at some overlapping positions of the yarns, and thus it is easy for the yarns to fall off at the joint points. In the present technical solution, since the diameter of the inner core wire in the polyester yarn is determined and the diameter of the polyester yarn is also fixed, the thickness of the polyester layer is determined. During the hot pressing process, a longer hot pressing time can be maintained to completely weld the outer polyester layer, that is, to connect the inner core wires of the overlapping polyester yarns, thereby ensuring a firm connection between the polyester yarns and preventing the joint points of the polyester yarns from falling off easily.

[0017] In Technical Solution 2, the polyester layer is made of 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.

[0018] In Technical Solution 3, the melting point ranges of the inner core wire and the polyester layer are limited. A larger difference in the melting point ranges can provide a greater redundant space during the manufacturing process to ensure that the produced shoe upper has the required structure.

[0019] In Technical Solution 4, the waterproof layer is formed by a waterproof and breathable membrane made of polytetrafluoroethylene (PTFE) material, which provides excellent waterproof performance to prevent external moisture from entering the shoe, while maintaining good breathability to ensure the feet are dry and comfortable. The PTFE material also has good chemical resistance and high temperature resistance, further improving the comprehensive performance of the shoe upper.

[0020] In Technical Solution 5, an antibacterial layer formed by bamboo charcoal fiber weaving is provided. Bamboo charcoal fiber can inhibit the growth of bacteria and molds, reduce odor problems caused by microbial reproduction, and has strong adsorption ability to adsorb odors and keep the shoe inner environment fresh and dry.

[0021] In Technical Solution 6, ventilation holes are also provided on the antibacterial layer, further improving the overall antibacterial effect of the shoe upper.

[0022] In Technical Solution 7, a contact layer is provided. The contact layer is formed by warp and weft weaving of contact fibers, and the contact yarns include ramie fibers and cotton fibers spirally wound around the ramie fibers. Ramie fibers have high strength and toughness, and as the core wires, they can ensure the overall strength of the contact fibers and reduce dimensional deformation. At the same time, cotton fibers are coated on the ramie fibers to improve the moisture absorption effect of the contact layer, and the cotton fibers are soft and comfortable, causing no irritation when in contact with the skin, thus improving the wearing comfort.

[0023] In Technical Solution 8, the antibacterial layer is stitched and connected to the shoe surface layer, and the contact layer is stitched and connected to the antibacterial layer to ensure a firm connection between the various layers of the shoe upper. The waterproof layer is sandwiched between the antibacterial layer and the shoe surface layer, which can prevent the waterproof layer from falling off.

[0024] In Technical Solution 9, a shoe is provided, which adopts the above-mentioned double-material string yarn shoe upper, and the connection between the shoe upper yarns is firm, and the joint points are not easy to fall off. Brief Description of the Drawings

[0038] Embodiment 1

[0039] Referring to Figure 1 , the embodiment of the present utility model provides a double-material string-wire shoe upper, and the shoe upper can be compounded to a prefabricated sole by means of bonding, hot melting or sewing, and the two cooperate to form a shoe.

[0040] Referring to Figure 2 , the double-material string-wire shoe upper provided in this embodiment sequentially includes a shoe surface layer 1, a waterproof layer 7, an antibacterial layer 8 and a contact layer 4 from outside to inside.

[0041] The shoe surface layer 1 is formed by laying polyester yarns in a single layer and / or multiple layers according to the shape of the shoe upper. Specifically, referring to Figure 3, when forming the shoe upper layer 1, a laying range can be delimited according to the shape of the shoe upper first, and then the polyester yarns are laid on a plane according to a predetermined direction. If a certain part of the shoe upper requires higher strength, the polyester yarns can be laid in multiple layers at the corresponding part. If a certain part of the shoe upper requires better breathability, the polyester yarns can be laid in a single layer at the corresponding part. At the position where multiple layers are laid, the overlapping polyester yarns form a connection relationship through hot melt pressing. At other positions, if the polyester yarns overlap during the laying process, a connection relationship can also be formed at the overlapping position through hot melt pressing. At the edge of the shoe upper, the polyester yarns arranged in other directions on the inner side can be connected into one body through the polyester yarns extending along the edge of the shoe upper. 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.

[0042] Among them, referring to Figure 3 , the polyester yarn includes a core wire 3, and a polyester layer 2 is coated on the core wire 3. The core wire 3 is made of a thermoplastic polyester elastomer material, and the polyester layer 2 is made of a thermoplastic polyurethane elastomer material; at the position where the polyester yarns are laid in multiple layers to form an overlap, the outer polyester layers 2 are bonded together by hot pressing, and the core wires 3 of the two are connected. Referring to Figure 4 , as described above, during the process of forming the shoe upper layer 1, the polyester yarns need to be connected into one body at the overlapping positions. Since the polyester layer 2 is made of a thermoplastic polyurethane elastomer material, during the manufacturing process, the polyester layer 2 of the polyester yarn can be partially melted by heating, so that the polyester layer 2 of the polyester yarn at the overlapping positions plays a connecting role and connects the polyester yarns at the overlapping positions into one body, thereby forming a mesh structure and making the shoe upper layer 1 have higher strength. Moreover, the core wire 3 is made of a thermoplastic polyester elastomer material, which has a higher melting point range compared with the thermoplastic polyurethane elastomer material used for the polyester layer 2, and has excellent mechanical properties. Its tensile strength and elastic modulus are high. As the core wire 3, it can provide better structural strength for the polyester yarn and prevent the shoe upper layer 1 from breaking and damaging due to intense exercise. During the forming process of the shoe upper layer 1, due to the different melting point ranges of the thermoplastic polyester elastomer and the thermoplastic polyurethane elastomer, a certain temperature can be used for hot pressing at the overlapping positions of the polyester yarns, so that the polyester layer 2 melts while the core wire 3 remains in a solid state. After cooling, the overlapping polyester yarns can be connected into one body through the polyester layer 2.

[0043] In similar shoe uppers in the prior art, since only one material, thermoplastic polyurethane elastomer, is used, it is often difficult to accurately determine the appropriate hot pressing time, resulting in too low a welding degree at some overlapping positions of the yarns, and thus it is easy for the yarns to fall off at the joint points. In the present technical solution, since the diameter of the inner core wire 3 in the polyester yarn is determined and the diameter of the polyester yarn is also fixed, the thickness of the polyester layer 2 is determined. During the hot pressing process, a longer hot pressing time can be maintained to completely weld the outer polyester layer 2, that is, to connect the inner core wires 3 of the overlapping polyester yarns, thereby ensuring a firm connection between the polyester yarns and preventing the joint points of the polyester yarns from falling off easily.

[0044] The polyester layer 2 is coated on the outside of the inner core wire 3. The thermoplastic polyurethane material has high elasticity, impact resistance, wear resistance and chemical stability. The polyester layer 2 can protect the inner core wire 3, and at the same time endows the shoe upper layer 1 with good elasticity and shape retention ability, enabling the shoe upper to adapt to the dynamic changes of the foot, having a better fitting effect, and further improving the structural stability of the shoe upper layer 1. Moreover, in this embodiment, the polyester layer 2 is made of aliphatic thermoplastic polyurethane material. Since the molecular structure of the aliphatic thermoplastic polyurethane material does not contain benzene rings, it can effectively reduce the chemical reactions caused by ultraviolet rays, thereby improving the yellowing resistance of the shoe upper layer 1. And instead of using a pure thermoplastic polyurethane wire directly as the yarn for manufacturing the shoe upper layer 1, the aliphatic thermoplastic polyurethane elastomer material is used as a coating layer and coated on the outside of the inner core wire 3. In this way, not only can the polyester yarn have good mechanical properties and weather resistance of thermoplastic polyurethane, but also the structural stability and waterproofness of the shoe upper layer 1 can be improved.

[0045] In this embodiment, the melting point range of the inner core wire 3 is selected to be 160°C - 180°C, and the melting point range of the polyester layer 2 is 90°C - 100°C. By defining the melting point ranges of the inner core wire 3 and the polyester layer 2, a larger difference in the melting point ranges can provide a greater redundant space during the manufacturing process to ensure that the manufactured shoe upper has the required structure.

[0046] Refer to Figure 2, the waterproof layer 7 is formed by pasting a waterproof and breathable membrane on the inner side of the shoe surface layer 1, and the waterproof and breathable membrane is made of polytetrafluoroethylene material. Setting the waterproof layer 7 on the inner side of the shoe surface layer 1 can provide a base for the waterproof layer 7 to be set and can be protected by the shoe surface layer 1 to prevent the waterproof layer 7 from falling off. The waterproof layer 7 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, while ensuring waterproofing, the waterproof layer 7 can also maintain the breathability of the shoe upper. 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 shoe surface layer 1 by pasting or methods such as hot pressing and sewing to ensure its close combination with the shoe surface layer 1 and is not easily detached or displaced.

[0047] The antibacterial layer 8 is located on the inner side of the waterproof layer 7 and is formed by weaving bamboo charcoal fibers in warp and weft directions. And a plurality of ventilation holes are provided through the bamboo charcoal fiber layer in the thickness direction. Bamboo charcoal fibers can inhibit the growth of bacteria and molds, reduce odor problems caused by the reproduction of microorganisms, and have strong adsorption ability to adsorb odors and keep the environment inside the shoes fresh and dry. Setting ventilation holes on the antibacterial layer 8 further improves the overall antibacterial effect of the shoe upper. The ventilation holes can be formed by leaving spaces at corresponding positions during the weaving process.

[0048] The contact layer 4 is located on the inner side of the antibacterial layer 8, and the contact layer 4 is formed by weaving contact yarns in warp and weft directions. Refer to Figure 5 , the contact yarn includes ramie fibers 5 and cotton fibers 6 coated on the outer side of the ramie fibers 5, and the cotton fibers 6 are spirally wound around the corresponding ramie fibers 5. The ramie fibers 5 have high strength and toughness. As the core wire, they can ensure the overall strength of the contact fibers and reduce dimensional deformation. At the same time, coating cotton fibers 6 on the outer side of the ramie fibers 5 can improve the moisture absorption effect of the contact layer 4, and the cotton fibers 6 are soft and comfortable, without irritation when contacting the skin, improving the wearing comfort. At the same time, the cotton fibers 6 are spirally wound on the outer side of the ramie fibers 5 to form the contact yarn, which can provide consistent performance in multiple directions and ensure the softness and comfort of the contact layer 4.

[0049] In addition, in this embodiment, the antibacterial layer 8 is sewn and connected to the shoe surface layer 1, and the contact layer 4 is sewn and connected to the antibacterial layer 8. At this time, the waterproof layer 7 can be clamped by the antibacterial layer 8 and the shoe surface layer 1, and at the same time, the waterproof layer 7 can also be bonded to the shoe surface layer 1. When sewing and connecting, polyester metal wire can be used. Polyester metal wire is a composite fiber obtained by plating metal on the surface of polyester or mixing metal powder with polyester fiber. It has good strength and elasticity and can ensure the firm connection between the shoe surface layer 1, the antibacterial layer 8 and the contact layer 4.

[0050] Embodiment 2

[0051] Embodiment 2 of the present utility model provides a shoe, which includes a sole and the shoe upper provided in Embodiment 1. The shoe upper is compounded with the sole by means of bonding, hot melting, sewing, etc. Since the shoe upper of Embodiment 1 is adopted, the connection between the shoe upper yarns of this shoe is firm and the bonding points are not easily detached.

[0052] The above description of the specification and embodiments is used to explain the protection scope of the present utility model, but does not constitute a limitation on the protection scope of the present utility model. Through the inspiration of the present utility model or the above embodiments, those of ordinary skill in the art, in combination with common general knowledge, ordinary technical knowledge in the art, and / or existing technologies, can obtain modifications, equivalent replacements, or other improvements to the embodiments of the present utility model or some of its technical features through logical analysis, reasoning, or limited experiments, and all of them should be included within the protection scope of the present utility model.
