[0086] Based on Embodiment 1, Embodiment 2, or Embodiment 3, the method further includes: adjusting the elasticity value of the jacquard mesh fabric by selecting different proportions of yarns during the weaving process. The yarns include yarns with elastic properties and yarns without elastic properties. The term "yarn with elastic properties" in this application does not limit the material, processing technology, or yarn structure, as long as the yarn is stretchable or imparts elasticity to the mesh fabric. Common yarns include: spandex core-spun yarn, semi-dull environmentally friendly low-elasticity lightweight mesh yarn, PTT yarn, bio-based elastic yarn, PTT blended yarn, TPEE blended yarn, etc.

[0087] Optionally, the jacquard protrusions 42 are divided into several protrusion areas, and the thickness of the jacquard protrusions 42 in different protrusion areas is different. The different protrusion areas are arranged adjacently and continuously or spaced apart.

[0088] Optionally, the jacquard protrusions 42 include at least two colors and are divided into a first-color jacquard protrusion and a second-color jacquard protrusion. The multi-comb jacquard three-dimensional jacquard mesh fabric containing the first-color jacquard protrusion and the second-color jacquard protrusion is woven by at least three jacquard combs.

[0089] Optionally, the thickness of the raised area can vary from the inside out or from the outside in, with the thickness varying in the horizontal or / and vertical direction.

[0090] Optionally, the upper can be made of multi-combed jacquard mesh, with elastic yarns woven in at least one location on the side, opening, or heel of the upper.

[0091] Optionally, the upper can be made of multi-combed jacquard mesh, with elastic and non-elastic areas customized by selecting yarns and / or basic weave structure.

[0092] Optionally, the upper is made of multi-combed jacquard mesh fabric, with jacquard protrusions 42 forming a support skeleton on the upper, which is woven from yarns that do not have elastic properties.

[0094] like Figure 4 As shown, Figure 4 The diagram shows a simplified illustration of jacquard protrusions 42 on surface layer 1, specifically, the outer jacquard protrusions 42 are thinner than the inner jacquard protrusions 42. For example... Figure 5 As shown, Figure 5A simple diagram of setting jacquard protrusions 42 on the surface layer 1 is given, specifically the thickness of the jacquard protrusions 42 in different protrusion areas is different, and different protrusion areas are arranged adjacent to each other.

[0095] Take the multi-bar jacquard three-dimensional mesh fabric as an example, which is used as the upper fabric, and the structure of the whole upper fabric includes the structure in the multi-bar jacquard three-dimensional mesh fabric, which is referred to as jacquard upper fabric, such as the structure of the jacquard protrusions 42 on the jacquard upper fabric.

[0096] Next, the application direction of the jacquard upper fabric is taken as an example. First, the elasticity of the shoe can be customized according to different areas, that is, at least one position of the shoe side, shoe opening and shoe heel of the shoe can be knitted with elastic yarns to change the elasticity of the corresponding position of the shoe; or, the yarns without elastic properties are used to lock the elasticity of the corresponding area to limit the elasticity of the corresponding area; or, the yarns with elastic properties or / and the yarns without elastic properties are arranged in the non-specified areas of the shoe to meet the daily life, sports, anti-rolling, and replace the original shoe structure, wherein the replacement of the original shoe structure includes replacing the original sponge in the shoe heel area by knitting jacquard protrusions 42;

[0097] Second, the height of the jacquard protrusions 42 of the shoe can be customized. One upper fabric can set jacquard protrusions 42 at multiple positions, or set jacquard protrusions 42 in a large area, or set jacquard protrusions 42 in a small area, or the jacquard protrusions 42 in the same area are continuously thickened or thinned, or the jacquard protrusions 42 in different areas of the shoe present a hierarchical transition, such as the first area jacquard protrusions 422mm, the second area jacquard protrusions 423mm, and the third area jacquard protrusions 425mm.

[0098] Finally, the jacquard structure such as the knitting pattern and the check pattern can be customized at the position of the shoe other than the jacquard protrusions, or the bottom surface can be non-holed, regularly holed, or custom holed, wherein the size, length and shape of the holes in the custom holed can be customized.

[0099] In the above, at least three jacquards are required to achieve custom holed, and two jacquards can achieve regular holed.

[0100] The following six kinds of jacquard uppers are taken as examples. The first kind, the upper structure comprises: jacquard protrusions 42, holes or / and no holes are opened on the jacquard protrusions 42, patterns are arranged on the non-jacquard protrusion positions on the upper, and corresponding structures are arranged on the face layer 1 and the bottom layer 2, and the upper formed by weaving 32 needles or more is more delicate; the second kind, the bottom layer 2 is not perforated or regularly perforated, and the face layer 1 is perforated or not perforated on the jacquard protrusions 42; the third kind, the jacquard protrusions 42 are arranged on the upper, and the jacquard protrusions 42 are freely perforated or jacquard, and the non-jacquard protrusion part can also be jacquard or perforated; the fourth kind, the subsequent jacquard protrusions 42 on the upper are gradually changed, and the direction of the gradual change of the jacquard protrusions 42 is not limited, which can be simultaneously gradually changed to the middle from the left and right sides, or simultaneously gradually changed to the left and right sides from the middle, or simultaneously gradually changed to the middle from the upper and lower sides, or simultaneously gradually changed to the upper and lower sides from the middle; the gradual change mode can be continuous or discontinuous; the fifth kind, the upper adopts double-color jacquard protrusions 42, taking red and blue jacquard protrusions 42 as an example, there are several red jacquard protrusions 42 and blue jacquard protrusions 42 on the upper; the sixth kind, the jacquard protrusions 42 on the upper are provided with gradually changed jacquard, the jacquard protrusions can also be perforated, the non-jacquard protrusions are freely perforated, and the bottom layer 2 is not freely perforated, and the bottom layer 2 can be regularly perforated.
