[0002] Due to good air permeability and comfortable wearing, knitted shoe uppers have been widely used in various sports shoes. The tongue of a traditional knitted shoe upper is usually formed by cutting and sewing a single material. Before sewing, the tongue is in a flat structure and needs to rely on shaping treatment to form a curved surface structure. However, although the shaping treatment can make the flat tongue form a curved surface structure, the tongue is prone to deformation after being used for a period of time, affecting the comfort and wrapping property of the shoe upper.
[0003] In view of this, the inventor of the present invention has conducted in-depth research on the above problems, and thus this case has arisen. Summary of the Invention

A spacing is formed between two adjacent first knitting areas, and the number of the second knitting areas is the same as that of the first knitting areas and they are arranged in one-to-one correspondence.
[0008] As an improvement of the present invention, the yarns used in the first knitting area and the second knitting area are both TPU-coated high-strength yarns or silicone-coated high-strength yarns.

[0021] The corresponding labels in the figure are as follows: 10 - surface layer; 11 - first knitting area; 20 - bottom layer; 21 - second knitting area; 30 - shrink knitting structure. Detailed Implementation Modes
[0022] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the terms "first", "second", etc. involved in the present invention are used to distinguish different objects, rather than describing a specific order.
[0023] This embodiment provides a knitted shoe upper, including a shoe upper body and a tongue connected to the shoe upper body, wherein the tongue is a knitted tongue. The shoe upper body and the tongue can be integrally connected by knitting, or can be connected by sewing, or can also be connected by gluing. It should be noted that when the knitted tongue is not integrally connected to the shoe upper body, the knitted tongue can be sold or used independently, that is, this embodiment essentially also provides a knitted tongue.
[0024] As Figures 1-2 shown, this embodiment provides a knitted tongue, including a surface layer 10 and a bottom layer 20 connected to each other. The specific connection structure between the surface layer 10 and the bottom layer 20 can be a conventional structure, using connecting yarns to fixedly connect the surface layer 10 and the bottom layer 20 to each other, or allowing the yarn part of the bottom layer 20 to be interwoven on the surface layer 10 to achieve connection, etc., which will not be elaborated here.
[0025] The surface layer 10 has a first knitted area 11 with a curved surface shape. The bottom layer 20 has a second knitted area at a position corresponding to the first knitted area, and the second knitted area is also curved. The number, position and curvature of the knitted areas can be selected according to actual needs to ensure that the curved surface of the tongue can accurately fit the physiological curve of the human foot, so as to improve the wearing comfort and fit of the shoes. In this embodiment, there are multiple first knitted areas 11, and all or part of the first knitted areas 11 are arranged side by side in sequence along the length direction or width direction of the surface layer 10. There is a spacing between two adjacent first knitted areas 11. The number of the second knitted areas is the same as that of the first knitted areas 11 and they are arranged in one-to-one correspondence, so that the curved surface shape of the tongue can be controlled by controlling the range, position and indirect of each knitted area when designing the tongue, and then the tongue can form a curved surface with a specific shape.
[0026] The first knitted area 11 and the second knitted area are pulled against each other to make the tongue twist and form a curved surface structure. In order to realize the mutual pulling of the first knitted area 11 and the second knitted area, one or more of the following structures can be set on the knitted area. In this embodiment, the following six structures are set on the knitted area at the same time as an example for description: The first structure is that the shrinkage rate of the yarn used in the first knitting area 11 is less than or greater than the shrinkage rate of the yarn used in the second knitting area, that is, the shrinkage rates of the yarns in the two corresponding knitting areas are different. In this way, a three-dimensional curved surface shape can be formed on the tongue of the shoe by using the natural shrinkage of the yarn. For example, when it is necessary to make a certain area of the tongue of the shoe arch upward, the shrinkage rate of the yarn in the first knitting area 11 can be made less than the shrinkage rate of the yarn in the second knitting area. The greater the difference in shrinkage rate between the two, the more obvious the curved surface of this area will be.
[0027] The second structure is that the diameter of the yarn used in the first knitting area 11 is less than or greater than the diameter of the yarn used in the second knitting area, that is, the thicknesses of the yarns in the two corresponding knitting areas are different. In this way, a three-dimensional curved surface shape can also be formed on the tongue of the shoe. The greater the difference in the thickness of the yarns between the two, the more obvious the curved surface of this area will be. It should be noted that the diameter of the yarn described here not only refers to the diameter of a single yarn, but also includes the diameter of a whole strand of yarn formed by arranging or twisting multiple yarns side by side.
[0028] The third structure is that the coil density of the first knitting area 11 is less than or greater than the coil density of the second knitting area, that is, a three-dimensional curved surface shape is formed on the tongue of the shoe by using the different coil densities of the two corresponding knitting areas. The greater the difference in coil density between the two, the more obvious the curved surface of this area will be.
[0029] The fourth structure is that the number of coil rows in the first knitting area 11 is less than or greater than the number of coil rows in the second knitting area, that is, a three-dimensional curved surface shape is formed on the tongue of the shoe by using the different numbers of coil rows in the two corresponding knitting areas. The greater the difference in the number of coil rows between the two, the more obvious the curved surface of this area will be. It should be noted that the number of coil rows refers to the stitch pitch occupied by a single coil during knitting, and the stitch pitch refers to the number of stitches per inch or per centimeter.
[0030] The fifth structure is that the thickness of the first knitting area 11 is less than or greater than the thickness of the second knitting area, that is, a three-dimensional curved surface shape is formed on the tongue of the shoe by using the different thicknesses of the two corresponding knitting areas. The greater the difference in thickness between the two, the more obvious the curved surface of this area will be.
[0031] The sixth structure is as Figure 3 shown. The number of coil rows in the area of the surface layer outside the first knitting area and the area of the bottom layer outside the second knitting area are both greater than the number of coil rows in the first knitting area or the second knitting area, and the number of coil rows in the first knitting area and the second knitting area are the same, and the positions of the first knitting area and the second knitting area correspond. Since the number of coil rows in the middle (the first knitting area and the second knitting area) of the surface layer and the bottom layer in the first knitting area and the second knitting area is less than that on both sides (the area outside the first knitting area and the area outside the second knitting area), an inward force will be formed by the extrusion of both sides towards the middle, so that the tongue of the shoe can naturally warp and stand up at this position. The standing angle can be adjusted according to needs, and multiple such structures can be knitted on the tongue body.
[0032] The yarns in each knitting area can be selected according to actual needs. In this embodiment, the yarns used in the first knitting area 11 and the second knitting area are both high-strength yarns with TPU coating or high-strength yarns with silicone coating. By setting the above-mentioned multiple structures at the same time, the mutual cooperation between different structures can be utilized to better control the curved surface shape and improve the fitting degree.
[0033] Preferably, the knitted tongue provided in this embodiment further includes a shrinkage knitting structure 30 integrally connected between the surface layer and the bottom layer. The shrinkage knitting structure 30 is located at the periphery of the surface layer 10 or the bottom layer 20. The specific structure of the shrinkage knitting structure 30 can be a conventional structure, such as ribbing, etc., as long as it can enhance the strength of the tongue periphery, and will not be elaborated here.
[0034] This embodiment also provides a manufacturing method for the above-mentioned knitted upper or knitted tongue, which includes the following steps: S1, design a three-dimensional tongue with a curved surface as shown in Figures 1-2 The three-dimensional tongue includes a surface layer 10 and a bottom layer 20 connected to each other. The surface layer 10 has a first knitting area 11 with a curved surface shape, and the bottom layer 20 has a second knitting area at a position corresponding to the first knitting area 11.
[0035] S2, make a knitting pattern as shown in Figure 4 According to the three-dimensional tongue. In the figure, A and B represent the yarn nozzles of the knitting machine, represents the moving mode of the knitting machine table, the abscissa represents the number of fabric columns, and the ordinate represents the number of fabric rows.
[0036] Then, knitting is carried out on the knitting machine according to the knitting pattern. The yarn used for knitting is a shaping yarn, preferably a high-strength yarn with TPU coating or a high-strength yarn with silicone coating. During the knitting process, one or more of the following methods are used to make the first knitting area 11 and the second knitting area pull on each other and form a curved surface structure on the tongue. In this embodiment, all of the following methods are used: The first method is that the shrinkage rate of the yarn used for knitting the first knitting area 11 is less than or greater than the shrinkage rate of the yarn used for knitting the second knitting area. Of course, the yarn needs to be pre-installed on the knitting machine before knitting.
[0037] The second method is that the diameter of the yarn used for knitting the first knitting area 11 is less than or greater than the diameter of the yarn used for knitting the second knitting area. The yarn also needs to be pre-installed on the knitting machine before knitting.
[0038] In the third method, the coil density of the first knitting area 11 is less than or greater than that of the second knitting area. There are multiple ways to adjust the coil density difference between the knitting areas. For example, during the knitting process, the coil density of the first knitting area 11 and the second knitting area can be adjusted by adjusting the clamping force of the yarn antenna clip of the knitting machine, adjusting the rotation speed of the yarn feeder of the knitting machine, and / or adjusting the tension of the yarn slingshot of the knitting machine. In addition, the adjustment of the coil density difference can also be achieved by setting the stitch density section in the knitting parameters on the control panel of the knitting machine. For example, the stitch density section corresponding to the first knitting area 11 is set to "8", and the stitch density section corresponding to the second knitting area 12 is set to "9", so that the coils on the first knitting area are loose and the coils on the second knitting area are compact, thereby forming a coil density difference.
[0039] In the fourth method, the number of coil rows in the first knitting area is less than or greater than that in the second knitting area.
[0040] In the fourth method, the knitting thickness of the first knitting area 11 is less than or greater than that of the second knitting area. As Figure 5 shown, in this embodiment, the number of coil rows in the second knitting area 21 of the bottom layer 20 is less than the number of coil rows in the area of the bottom layer 20 that is not the second knitting area, while the number of coil rows in the area of the surface layer 10 corresponding to the area on the bottom layer 20 Figure 5 is the same as the number of coil rows in the area of the bottom layer 20 that is not the second knitting area, and the number of coil knitting rows in the first knitting area 11 corresponding to the second knitting area 21 of the bottom layer 20 is greater than that of the second knitting area 21; Or as Figure 5 shown, the coil situation of the first knitting area corresponding to the surface layer 10 is the same as that of the non-second knitting area of the bottom layer 20, which is full knitting, and the second knitting area 21 of the bottom layer 20 is empty needle knitting (the knitting action of the empty needle knitting is the same as that of the 37th - 38th knitting columns in the 24th knitting row as Figure 4 shown).
[0041] In the fifth method, the knitting thickness of the first knitting area 11 is less than or greater than that of the second knitting area.
[0042] In the sixth method, the number of coil rows in the area of the surface layer where there is no first knitting area and the area of the bottom layer where there is no second knitting area are both greater than the number of coil rows in the first knitting area or the second knitting area, and the number of coil rows in the first knitting area and the second knitting area are the same. As Figure 4 shown in, when the first knitting area and the second knitting area are in the 40th - 47th knitting rows, the coil knitting rows on the left side of the surface layer and the bottom layer (the 3rd - 9th knitting columns) are more than those in the first knitting area and the second knitting area (the 10th - 54th knitting columns) (as Figure 4 shown in the part without knitting action (the 40th - 37th knitting rows), the number of coil rows is less). It should be noted that Figure 3 shown in the effect),Figure 3 The reference numeral 21 in the drawing at the second knitting area is from the perspective of a bottom plan view. There is actually a surface layer 10 below it, and the first knitting area 11 of the surface layer 10 is Figure 3 in one-to-one correspondence with the second knitting area 21, and the position 20 of the bottom layer corresponds to the position 10 of the surface layer one by one.
[0043] After knitting, a knitted blank is obtained. If there is no post-treatment requirement, the knitted blank can be directly used as a knitted shoe tongue. In order to improve the accuracy of the curved surface size of the shoe tongue, in this embodiment, the knitted blank is also subjected to a shaping treatment. The shaping treatment can be a conventional heat setting treatment, an injection molding treatment, a coating treatment or a compression molding treatment, which will not be elaborated here.
[0044] The present invention has been described in detail above with reference to the drawings. However, the embodiments of the present invention are not limited to the above embodiments. Those skilled in the art can make various deformations to the present invention according to the prior art, and these all belong to the protection scope of the present invention.
