Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of shoe uppers, and specifically relates to a three-dimensional shoe upper formed integrally. Background Art
[0002] Traditional three-dimensional shoe uppers are mostly formed by offset printing and seamless methods. Although this post-process method can make the shoe upper have a certain three-dimensional sense, due to the need for colloid for pasting, glue marks may appear around the three-dimensional decorative parts pasted on the shoe upper, and the overall integration of the shoe upper is not strong. To solve the above problems, this case is proposed. Summary of the Invention
[0003] The utility model provides a three-dimensional shoe upper formed integrally, which overcomes the deficiencies described in the background art.
[0004] The technical solution adopted by the utility model to solve its technical problems is as follows:
[0005] A three-dimensional shoe upper formed integrally includes a basic shoe upper, and a plurality of surface layers with filling spaces are integrally sewn or integrally formed by knitting on the basic shoe upper. High-temperature fusible yarns are filled in the filling spaces, and the surface layers are integrally adhered to the basic shoe upper by melting the high-temperature fusible yarns.
[0006] A preferred technical solution: Non-high-temperature fusible yarns are also arranged in the filling spaces.
[0007] A preferred technical solution: The high-temperature fusible yarns and the non-high-temperature fusible yarns are filled in different regions through a partition layer. The surface layer is divided into a flat region and a three-dimensional region. The high-temperature fusible yarns are filled in the flat region or the three-dimensional region, and the non-high-temperature fusible yarns are filled in the three-dimensional region.
[0008] A preferred technical solution: The surface layer filled with high-temperature fusible yarns forms a three-dimensional structure and / or a flat structure on the surface layer through a hot press.
[0009] A preferred technical solution: The surface layer filled with high-temperature fusible yarns forms a three-dimensional structure and / or a flat structure on the surface layer through a thermoforming machine.
[0010] A preferred technical solution: The three-dimensional structure and the flat structure cooperate to form a concave-convex structure.
[0011] A preferred technical solution: Multiple three-dimensional structures are combined to form a layered three-dimensional structure or a three-dimensional texture structure.
[0012] A preferred technical solution: The high-temperature fusible yarn is any one of hot melt yarn, thermoplastic polyurethane elastomer yarn, and thermoplastic polyester elastomer yarn.
[0013] A preferred technical solution: The non-high-temperature fusible yarn is any one of polyester yarn, cotton yarn, linen yarn, and wool yarn.

[0023] Embodiment 1
[0024] As Figures 1-3 shown, this embodiment provides an integrally formed three-dimensional shoe upper, including a basic shoe upper 1. A plurality of surface layers 11 with filling spaces 12 are integrally sewn or integrally formed and woven on the basic shoe upper 1. High-temperature fusible yarns 13 are filled in the filling spaces 12, and the surface layers 11 are integrally attached to the basic shoe upper 1 by melting the high-temperature fusible yarns 13.
[0025] Furthermore, non-high-temperature fusible yarns 14 are also provided in the filling spaces 12.
[0026] Further, the high-temperature fusible yarn 13 and the non-high-temperature fusible yarn 14 are filled in different regions through the partition layer 15. The surface layer 11 is divided into a flat region 21 and a three-dimensional region 22. The high-temperature fusible yarn 13 is filled in the flat region 21 or the three-dimensional region 22, and the non-high-temperature fusible yarn 14 is filled in the three-dimensional region 22. The partition layer 15 can be formed by sewing with a needle and thread. For example, when the flat region 21 is adjacent to the three-dimensional region 22, they are separated by the partition layer 15, and are efficiently filled in the corresponding regions through a yarn filling device. Usually, the filling connection point is located on the back side of the shoe upper.
[0027] Further, the surface layer 11 filled with the high-temperature fusible yarn 13 is hot-pressed on the surface layer 11 by a hot press to form a three-dimensional structure and / or a flat structure.
[0028] Further, the three-dimensional structure and the flat structure cooperate to form a concave-convex structure.
[0029] Further, the high-temperature fusible yarn 13 is any one of a heat-melting wire, a thermoplastic polyurethane (TPU) elastomer yarn, and a thermoplastic polyester elastomer (TPEE) yarn. Among them, the thermoplastic polyurethane elastomer yarn refers to the TPU yarn, and the thermoplastic polyester elastomer yarn is the TPEE yarn. Taking the TPU yarn as an example, its melting point is about 200°C. When preparing by hot pressing on a hot press, the hot pressing temperature of the machine should be higher than 200°C. To ensure the hot melting effect, the hot pressing temperature in actual application is usually set at 230°C.
[0030] Further, the non-high-temperature fusible yarn 14 is any one of a polyester thread, a cotton yarn, a linen yarn, and a wool yarn.
[0031] Not limited to the above yarns, the non-high-temperature fusible yarn 14 in the present utility model can be understood as any ordinary conventional yarn. Since the non-high-temperature fusible yarn 14 does not need to play a pasting role in the filling space 12, any discarded yarn can be used. In the knitting industry, there are often yarns with unqualified physical properties that cannot be used, or yarns with unqualified colors. These "discarded" yarns can be filled into the three-dimensional region 22. By filling enough yarns, the corresponding surface layer 11 is supported to present a three-dimensional structure. These yarns can be recycled to turn waste into treasure, and to a certain extent, the preparation cost of the shoe upper is reduced.
[0032] Embodiment 2
[0033] This embodiment provides a one-piece molded three-dimensional shoe upper. The difference between this embodiment and Embodiment 1 is that the surface layer 11 filled with the high-temperature fusible yarn 13 forms a three-dimensional structure and / or a flat structure on the surface layer 11 through a thermoforming machine. The existing thermoforming machine also has a heating function, which can melt the high-temperature fusible yarn 13 so that the high-temperature fusible yarn 13 plays a pasting role.
[0034] Embodiment 3
[0035] This embodiment provides a three-dimensional shoe upper formed integrally. The difference between this embodiment and Embodiment 1 is that a plurality of three-dimensional structures are combined to form a layered three-dimensional structure or a three-dimensional texture structure. When using an existing hot press machine to prepare, it can be selected to change the mold on the hot press machine, so that after hot pressing, the corresponding layered three-dimensional structure or three-dimensional texture structure is formed at the corresponding position of the shoe upper.
[0036] Embodiment 4
[0037] This embodiment provides a three-dimensional shoe upper formed integrally. The difference between this embodiment and Embodiment 1 is that a front lining area is provided in the toe area of the basic shoe upper 1, and high-temperature fusible yarn 13 is filled in the front lining area, and a front lining piece is integrally formed by melting the high-temperature fusible yarn 13.
[0038] The integrally formed front lining piece in the present utility model can replace the traditional front lining. First, the process of pasting the front lining piece can be omitted. Second, for the integrally formed front lining piece in the present utility model, after the shoe upper is made into a shoe, the comfort during wearing can be improved to a certain extent.
[0039] The above is only a preferred embodiment of the present utility model, and thus the scope of implementation of the present utility model cannot be limited thereby. That is, equivalent changes and modifications made according to the scope of the present utility model patent and the content of the specification should still fall within the scope covered by the present utility model.
